Fabrication of complete dentures for an older patient with mobility impairment in three appointments: A dental technique.

To describe the clinical procedures of complete denture set fabrication in three appointments. Simplified approaches have proven not to be inferior to conventional ones in terms of quality, patient satisfaction and masticatory ability. The patient was a 77-year-old edentulous adult with mobility impairment seeking dental rehabilitation in a small number of appointments due to commuting difficulties. A set of complete dentures was delivered within three appointments. The second appointment was dedicated to set-up trial due to the patient's aesthetic demands. Under certain circumstances and after a thorough study of each case, dental clinicians may propose the fabrication of complete dentures in a three-appointment protocol incorporating a set-up trial session.

Evaluating the chewing efficiency of complete dentures using bilateral balanced occlusion and lingualized occlusion: A comparative study

Background -Dentistry plays one of the major role in the battlefield of medical sciences. It covers the major part of the human body which deals with the complex orofacial structures and associated complex stomatognathic system. The complex stomatognathic system has to be maintained in every pathological or abnormal condition like partial to complete edentulism. The maintainance of the stomatognathic system is significantly dependent on the branch of dentistry that deals with the part or complete replacement of lost or missing functional and complex structures known as prosthodontics. The occlusion serves the basic function of the complete denture prosthesis as one of the central goal of complete denture therapy is restoring occlusion. The occlusal scheme is still the topic of debate (that which occlusal scheme is best suited for the complete denture prosthesis), as no occlusal scheme has proved best in all cases. It is revealed that the choice of occlusal scheme used in complete denture prosthesis is primarily to the practitioners personal preference and experiences that varies from patient to patient. Aim -The purpose of this study was to evaluate the chewing efficiency of two different occlusal schemes i.e. conventional bilateral balanced occlusion and bilateral balanced lingualized occlusion in complete denture patients. Method- 20 edentulous patients aged between 40 - 70 years with a mean age value of 55 years attending among the out-patient department of Patna Dental College and Hospital Patna, were selected for the present study. A thorough screening of general and systemic health is carried out and found free of all major systemic diseases. After the selection of the patients it was decided that all the 20 patients were provided complete denture with conventional bilateral balanced occlusion and after 45 days of post insertion of the newly fabricated complete dentures, the patients were recalled and asked for the subjective qualities of the complete denture. Result -Confirming better chewing ability by BBLO than CBBO. Conclusion- The result of the present study concludes that the complete dentures with BBLO performed significantly better chewing ability than CBBO Since in the present study, all the test were carried out with same set of complete dentures by modifying CBBO to BBLO upon the same patient, which had not been taken into account by any of the previous studies. All the previous studies had used two different set of complete dentures with two different patients. Thus, this is a remarkable milestone in the present study providing a definite authenticity of the study.

SINGLE IMPLANT-RETAINED MANDIBULAR OVERDENTURE: A CASE REPORT

Edentulism is a public health problem, impacting the quality of life of many people worldwide. Factors related to the mandibular ridge minimal support may hinder the common use of complete dentures. The use of overdentures supported by a minimum of one implant can be considered as reliable approach in this situation. Aim: To present a case report of a single implant-supported overdenture in the mandibular symphysis fot public health policies. Case report: A 65-year-old edentulous patient complaining of discomfort in a mandibular denture was referred to the Universidade Federal Fluminense. On clinical examination, residual mandibular ridge resorption and soft tissue trauma were observed, which was in line with the reported discomfort. A mandibular overdenture retained by a single implant in the symphysis region was planned. A hex-type 4.0 mm in diameter and 11.0 mm in length implant was placed and a new set of complete dentures were made till the date of complete osseointegration. After four months, a second surgery exposed the implant platform to fit a ball attachment with a 32 N.cm torque. The denture was relieved on its tissue surface for the placement of a metal attachment matrix with a rubber O-ring inside, using a fast-curing resin, and the patient was locked into maximum intercuspidation during the acrylic polymerization process. Excessive resin was removed and the region was polished for daily use after the process. The patient reported an improvement in chewing condition and restorative esthetics. Conclusions: A minimum requirements protocol has achieved relevant results and may be feasible in public health policies. Maintenance visits are recommended to maintain retention quality and to decrease the risk of failures.

Precision and accuracy of digital smile analysis in removable complete denture

Background/aim Digital Smile Design (DSD) software is a beneficial approach to the potential of patient smile enhancement by producing an esthetic treatment plan. This study aimed to evaluate the precision and accuracy of hand calibrated, photo analysis, and DSD method in removable complete dentures and correlate them with different types of denture teeth. Patients and methods This study was conducted on 29 completely edentulous patients selected from the Outpatient Clinic of Prosthodontic Department, Faculty of Oral and Dental Medicine, Badr University, Egypt. Each patient received two sets of complete dentures as follows: the first denture was constructed from a conventional complete denture with cross-linked resin teeth and served as the control group (group I), and the second denture was constructed from conventional complete denture with nanohybrid composite teeth and served as the test group (group II). Each group was further subdivided into three subgroups, according to the different smile analysis techniques performed: subgroup A, hand calibrated method; subgroup B, photo analysis method, and subgroup C, DSD method. Then, precision and accuracy were evaluated for each smile variable. Results Mean absolute difference was calculated between group I and group II for each smile analysis technique, revealing that the least amount of difference between groups was illustrated in the subgroup A followed by subgroup C and finally subgroup B, which revealed the maximum amount of difference between groups ranged from 0.0031 to 0.2623. Cronbach's Α was calculated for group I and group II between each smile analysis technique, revealing that all was less reliable (less accurate), except lower teeth exposure in group II was rather reliable (rather accurate) ranging from 0.023 to 0.784. Conclusion With the respect to limitations of this study regarding individualized anatomical variations and distortion liability of the image, it was concluded that nanohybrid resin composite denture teeth had less deviation (higher precision) than the conventional acrylic resin denture teeth regarding the ratio of different smile parameters with facial proportions.

Correlation of Salivary Cortisol Levels with Anxiety in Type II Diabetes Mellitus Patients before and after Complete Denture Rehabilitation - An in vivo Study

Background: Complete edentulism constitutes health care burden, resulting in alterations in physical, psychological and emotional behavior. Also, a reduction in quality of life is expressed by patients, raising their levels of stress and anxiety. Stressful situations cause increased blood pressure and heart rate resulting in the secretion of cortisol hormone, which stimulates gluconeogenesis and glycogenolysis causing hyperglycemia, which may favor the occurrence of Diabetes. As the diabetic’s population is rapidly rising, Prosthodontists are certain to see a greater number of diabetic edentulous patients. Thus, there is a need to assess the relationship of complete denture rehabilitation with the generic health of edentulous patients which can be done by checking the stress levels, and their effects on systemic health.
 Objectives: To determine anxiety levels and Salivary Cortisol levels in Type II Diabetes Mellitus patients and compare and correlate them before and after rehabilitation with Complete Dentures.
 Methodology: It will be a cross-sectional study, carried out on edentulous diabetic patients aged 50-70 years visiting the Department of Prosthodontics of Sharad Pawar Dental College and Hospital. With consent for participation, Glycated Hemoglobin and anxiety levels will be determined, along with fabrication of complete dentures. Patients will be assessed at two stages; before and 1 month after complete denture rehabilitation.
 Results: The research has been approved by the Institutional Ethical Committee. The results expected are the significant reduction in anxiety levels after Complete Denture Rehabilitation and thus, a definitive correlation between anxiety and salivary cortisol levels.
 Conclusion: Adaptation of patients to their new set of Complete dentures can be improved by their clinicians by acquisition of the knowledge of relationship of the general health of the patient and correlating it to the dental rehabilitation.

Masticatory efficiency in complete denture and single implant-retained mandibular overdenture wearers with different occlusion schemes: A randomized clinical trial

Statement of problemHow the masticatory function of complete denture wearers is influenced by the positioning and occlusion of posterior teeth or by the presence of a single mandibular implant is unclear. PurposeThe purpose of this randomized crossover clinical trial was to evaluate the masticatory efficiency of wearers of bimaxillary complete dentures and of wearers of maxillary complete denture and single implant-retained mandibular overdentures, both with bilateral balanced occlusion and lingualized occlusion. Material and methodsParticipants received 2 sets of complete dentures with interchangeable teeth in the mandibular prosthesis to allow a change in the occlusion scheme. Subsequently, 1 implant was placed in the mandibular symphysis region, and the mandibular complete dentures were converted to overdentures. The masticatory efficiency was measured by the sieve method for both occlusal schemes. ResultsRepeated measures ANOVA showed no statistically significant difference in the masticatory efficiency with the 2 occlusal schemes for conventional complete dentures (P=.707) or overdentures (P=.407). When comparing the type of prosthesis, statistical differences were found for masticatory efficiency (P=.012), with improved mastication for the overdentures. ConclusionsA mandibular single implant improved the masticatory efficiency of patients with complete dentures, but the occlusal scheme did not influence this factor.

Comparing Oral Health-related Quality of Life (OHIP-14) and Masticatory Efficiency with Complete Denture Treatment.

To measure impact of oral health in complete denture wearers and its effects on masticatory efficiency with new complete dentures over the period of three months. Experimental study design. Department of Prosthodontics, Bahria University Medical and Dental College, Karachi, Pakistan from September 2019 to December-2019. Oral health impact profile (OHIP) was used to measure the oral health impact; and chewing gum method was used to measure the masticatory efficiency in this study. All participants were old denture wearers having the experience of at least 3 years and requiring new set of complete dentures. A total of 31 patients were asked to chew the gum from the routine site of mastication for 20 seconds. The weight reduction corresponded to the masticatory efficiency. The OHIP-14 score and masticatory efficiency was recorded at baseline and after three months of complete denture treatment. The data was analysed on SPSS version 23. The average values of masticatory efficiency were significantly reduced from median (IQR) value 1.20 (1.20-1.30) to 0.90 (0.70-0.90), respectively (p <0.001). There was a moderate positive correlation for physical pain and disability (0.407 and 0.455) at baseline and strong positive correlation (0.771 and 0.825) after 3 months of complete denture treatment with p-value <0.001 on OHIP-14 scale. Statistically significant improvement was observed in both quality of life and masticatory efficiency after 3 months of treatment with conventional complete dentures. Masticatory efficiency was highly correlated with all subscales of OHIP-14 after treatment. Key Words: Complete denture treatment, Masticatory efficiency, Oral health impact profile-14 (OHIP-14).

A Seven-year Follow-up Study of Patient Satisfaction with Three-implant-retained Mandibular Overdentures

PURPOSE: This study aimed to compare patients’ satisfaction with mandibular overdentures retained by three-splinted implants versus conventional complete denture wearers during a 7-year follow-up study period. MATERIALS AND METHODS: Thirty edentulous male patients (mean age: 60 years) were carefully selected and divided into two equal groups. All patients received a new set of complete dentures. Group I patients received three implants in the anterior mandible and were connected after 3 months with bars, clips, and loaded. Group II patients received conventional complete dentures. Patients’ satisfaction was recorded for both groups at 3 weeks (baseline) and after 1, 3, 5, and 7 years. Patients were then asked to grade their overdentures/dentures on a visual analog scale and written questionnaire to evaluate their overall satisfaction. RESULTS: Satisfaction scores of Group I patients were found to be statistically significantly higher than that of Group II patients (p &lt; 0.05) at 3, 5, and 7 years follow-up, meanwhile, no statistically significant difference was found at baseline or after 12 months. CONCLUSION: The long-term results suggest that three-implant-retained mandibular overdenture with a clip-bar attachment appears to be a successful rehabilitation strategy which is superior to conventional dentures for patients with advanced ridge resorption.

Effectiveness of silicone-based resilient denture liners on masticatory function: A randomised controlled trial

ObjectivesThis randomised controlled trial aimed to compare the masticatory function between the silicone-based resilient denture liner and conventional denture among edentulous patients. MethodsThe trial included edentulous patients who were willing to have a new set of complete dentures. Participants were randomly assigned to receive mandibular complete dentures with either a 1) conventional denture base (CD group) or (2) silicone-based resilient denture liner (RD group). Masticatory performance (evaluated with gummy jelly) and the maximum occlusal force were measured at baseline, on final adjustment, and at 3 months after the final adjustment. The outcomes were analyzed using two-way mixed analysis of variance and a paired t-test. The statistical significance was set at p < 0.05. ResultsThe masticatory performance was lower in the RD group than in the CD group; it increased significantly over time in the CD group, but not in the RD group. The maximum occlusal force in the RD group was significantly higher than that in the CD group; it increased significantly over time in the RD group, but not in the CD group. ConclusionsSilicone-based RD liners applied to mandibular complete dentures are effective in improving the maximum occlusal force but not the masticatory performance, as measured with gummy jelly. Clinical significancePrior evidence has suggested that mandibular complete dentures with resilient denture liners improve masticatory function. However, the results of this study indicate that difficulties may remain with the mastication of foods with a certain texture (e.g., gummy jelly).

Effectiveness of silicone-based resilient denture liners on the patient-reported chewing ability: A randomized controlled trial.

This randomized controlled trial (RCT) aimed to elucidate the effectiveness of silicone-based resilient denture liners on perceived chewing ability. The RCT included completely edentulous patients on both the maxilla and mandible, who were willing to fabricate a new set of complete dentures. A random permuted block method (block size: 4) was used to assign groups to receive maxilla conventional complete denture and mandibular with either a conventional complete denture (CD) or complete demure relined with silicone-based resilient denture liner (RD). The patient-reported chewing ability of six foods, soybean curd, fish sausage, soybean sprout, cubic rice cracker, hard rice cracker, and dry squid, on a 100-mm visual analog scale was measured and reported at the final adjustment and three months after the final adjustment. Mann-Whitney U test was used to analyze the differences between the CD and RD (p < 0.05). Edentulous patients wearing mandibular complete denture with RD had a higher patient-reported chewing ability than those wearing a CD, but the fish sausage did not in the RD three months after the final adjustment. It also took three months for the patient-reported masticatory ability to improve for cubic rice crackers, hard rice crackers, and dry squid and to show a difference between the RD and CD groups. Although limited to some food types, mandibular complete dentures relined with silicone-based liners improved patient-reported chewing ability.

Comparison of chewing activity in patients requiring complete denture with two different occlusions

Background and Objectives: The loss of natural teeth causes many problems; one of major problems that are associated with edentulousness is the hypotonicity of muscles of mastication and decreasing the ability of the patient to chew food properly. Treatment of edentulous patients with complete denture will increase the muscle tonicity and chewing activity. The purpose of this study is to clinically compare patient's chewing ability between lingualized occlusion complete denture and bilaterally balanced occlusion complete dentures. Materials and methods: Two sets of complete dentures with different occlusions were fabricated for ten patients. The patients received bilaterally balanced occlusion (BBO) complete denture and lingualized occlusion (LO) complete denture in random order. The patients wear each set of complete denture for one month. During this month, chewing activity tests were performed for the patients in four different time intervals. The results of these tests were analyzed using t-test and paired t-test to compare between the lingualized occlusion and bilaterally balanced occlusion complete denture and also to compare the results of each time interval with each other. Results: The mean amount of the walnuts that passed through the sieve in LO dentures were (1.78g), during the fourth visit while it was (1.18g) in BBO. There were statistically significant difference between LO and BBO schemes of complete denture when measuring the amount of the chewed walnuts that passed through the sieve in second, third and fourth visit (p=0.037, 0.001 and 0.000). Conclusion: Within the limitations of this study, it has beenconcluded that the chewing ability was higher in patients who were provided with complete dentures fabricated with the LO scheme as compared to those patients who received complete dentures made with BBO scheme. This was due to the fact that LO technique resulted in functionally better complete dentures as compared to the ones made by BBO technique

Is a Ridge Classification Helpful when Assessing Edentulous Patients?

The edentulous ridge classifications most commonly used have their limitations in treatment planning. They do not provide an indication of the complexities that may occur when constructing a new set of complete dentures. The new classification system suggested in this article helps with improved record-keeping, information exchange between colleagues, and communication between patient and clinician. CPD/Clinical Relevance: The new edentulous ridge classification system links the various edentulous ridge shapes to possible complications that could arise during denture construction.

The effects of silicone-based resilient denture liners on pain: A randomized controlled trial

PurposeThis randomized controlled trial aimed to study the effects of lining mandibular complete dentures with silicone-based resilient denture liners, especially with respect to sensation. MethodsThe trial included completely edentulous patients who were willing to fabricate new set of complete denture. A random permuted block method (block size: 4) was used to assign participants to one of the following groups: mandibular conventional denture (CD) group or mandibular denture with resilient denture liner (RD) group. The outcomes were evaluated using both, objective measures (current perception threshold (CPT) and pain threshold (PT)) for external stimuli measured using the Neurometer CPT® and subjective measures (physical pain and psychological discomfort measured using the Japanese version of Oral Health Impact Profile for Edentulous patients—OHIP-EDENT-J). The outcomes were measured twice, at immediately after completion of denture adjustments (first measurement), and 3 months after the completion of denture adjustments (second measurement). All outcomes were analyzed using the Student t-test. A p-value of <0.05 was considered statistically significant. ResultsCPT was significantly higher with RD than CD only at second measurement with frequency level of 2000 Hz and 5 Hz. The pain thresholds were significantly higher in the RD group than the CD group. The physical pain and psychological discomfort scores were significantly lower in the RD group than in the CD group. ConclusionThis study concludes that edentulous patients wearing mandibular complete dentures with silicone-based resilient denture liners dull perception mandibular ridge mucosa and felt less pain than those without the liners.

An in vivo study to record bite force until denture dislodgement of an existing and new maxillary denture with and without use of denture adhesive

OBJECTIVES: Thoughadequate retention is a basic requirement, there are situations in which it is not possible to obtain desirable optimal retention. Because of ill effects to supporting tissues due to many mechanical aids for retention, many patients frequently resort to the use of denture adhesives. Due to technique sensitivity and limitations of many techniques to measure the retention of a complete denture, this study was planned to evaluate and compare the BFDD with the following aims and objectives; • To measure BFDD in an existing denture without and with use of denture adhesive. • To measure BFDD in new denture without and with use of denture adhesive. • To compare BFDD between an existing and new denture without and with use of denture adhesive. METHODOLGY: Among total of twenty edentulous subjects, Group I&amp; Group II for Method A &amp; B were made. The data obtained by BFDD measurements were statistically analyzed using ANOVA for different time intervals and student’s t-test for group wise comparison. RESULTS AND CONCLUSION: The results of the study showed that consistent improvements were observed in BFDD when adhesive was used. The p-value was highly significant (p&lt;0.001 HS) at all time intervals for both existing and new set of complete dentures.

The Extent and Scope of Prosthodontic Practice in Iowa.

The purpose of this questionnaire was to ask general dentists in private practice in the state of Iowa about the extent and scope of their prosthodontic practice. A 22-item questionnaire was developed and tested on 5 general dentists. The Iowa Dental Association agreed to electronically distribute the survey to all general practice dentists in their database. After three rounds, a total of 289 responses were received from the 996 general dentists in the database. The average age of the respondents was 50.3 ± 13.2 years (range 28 to 78 years), and 56.3% were in solo practice. The respondents stated that 68.1% had made at least one set of complete dentures and 88.9% had made a removable partial denture (RPD) in the last 3 months, while 76.4% had restored a least one implant in the last 3 months and 11.6% had surgically placed one. Nearly 20% of the respondents had a digital impression scanner in their office. There was a statistically significant difference between the dentists who had made complete dentures in the past 3 months and those who had not with regard to age, gender, and years in practice (p < 0.05 for all instances). No significant difference was found between the general dentists who had made an RPD in the past 3 months and those who had not. Compared to their counterparts, general dentists who had an AEGD or GPR training (p = 0.0312), whose primary practices were in cities of 50,000+ (p = 0.0065), or had a digital scanner (p = 0.0062) and a CAD/CAM milling machine (p = 0.0504) in their office were more likely to have restored an implant in the last 3 months. Furthermore, the general dentists who had surgically placed an implant in the last 3 months were more likely to be male (p = 0.0301) or have a digital impression scanner (p < 0.0001) and/or a CAD/CAM milling machine (p = 0.0007) in their office. The majority of general dentists in this survey are still making complete and partial removable dentures, and a majority is using implants, while only a minority is surgically placing them. PRACTICAL IMPLICATIONS: Although Iowa general dentists are carrying out sophisticated procedures such as implant placement and restoring implants, as well as using digital technology, there is still a need for removable prosthodontic services in their practices. Therefore, these skills will still need to be taught in dental school.

Three-year Prospective Evaluation of Immediately Loaded Mandibular Implant Overdentures retained with Locator Attachments

Immediate implant-loading protocol has progressed because of various clinical advantages offered by this treatment approach. However, available studies on edentulous patients are still few compared to those in which delayed implant-loading protocol was applied. This prospective study was to evaluate the implant survival rate and the peri-implant tissue response in a group of patients who received two unsplinted immediately loaded dental implants in the mandibular anterior region to retain a complete overdenture using locator attachments. A total of 24 edentulous patients with a mean age of 63.4 years were involved in this study following certain inclusion criteria. All patients received a new set of complete dentures before implant positioning. Two Prima Connex tapered implants were put in the interforaminal area of the mandible with a flapless surgical procedure, and the prefabricated dentures were immediately retained with a zest locator attachment. Clinical and radiographic records of the patients were reviewed immediately after placement of the implant, at 3 months, and at 1, 2, and 3 years following fixture installation. The obtained data were analyzed using paired samples t-test and the Wilcoxon signed-rank test at 0.05 significance level. At 3 years, all implants had osseointegrated with a 100% survival rate. In addition, the total mean marginal bone change was -0.89 ± 0.14 mm, and the mean periotest value was -7.631 ± 0.921. Results of this study propose that immediate loading of mandibular implant overdentures that are retained with locator attachments was a feasible treatment alternative for this particular group of patients. Immediate implant- loading of mandibular implant overdentures that are retained with locator attachments is a reliable treatment option Keywords: Immediate implant loading, Implant survival rate, Locator attachments, Overdenture.

Does immediate loading affect clinical and patient-centered outcomes of mandibular 2-unsplinted-implant overdenture? A 2-year within-case analysis

ObjectiveTo provide 2-year clinical- and patient-oriented data with regard to mandibular overdenture assisted by 2 immediately loaded unsplinted implants. Material and methodsIn this pre-post design, Phase-I clinical trial, 18 edentate individuals (62.4±7.7years) received a new set of complete denture. Then, following standard procedures, 3 threaded implants (OsseoSpeed TX™, Dentsply Implants, Mölndal, Sweden) were placed in the mandible in each patient, and locator abutments (Zest Anchors LLC, Escondido, U.S.A.) were inserted on the right and left side implants. The midline implant served as a control for within-patient comparison. The immediate loading was conducted within 24h of surgery. Data were collected at baseline (T0), 12 (T1) and 24 (T2) months after immediate loading. The clinical outcomes included implant survival rate, crestal bone level changes and implant stability. These criteria were assessed through clinical and radiographic examinations as well as resonance frequency analysis. Patient-centered outcomes included patient satisfaction and oral health-related quality of life measured using validated questionnaires. Brunner-Langer approach was used for statistical analysis. ResultsImplant survival rate for immediate loaded implants was 91.7% at 2-year follow-up. None of the unloaded implants failed. There was no statistically significant difference at baseline and follow-ups with regard to clinical outcomes between loaded and unloaded implants. Patient satisfaction and quality of life improved (p<0.0001) from baseline to 2-year follow-up. ConclusionImmediate loading protocol did not negatively affect clinical outcomes, satisfaction and quality of life of patients wearing 2-unsplinted-implant mandibular overdenture for 2 years. This conclusion requires confirmation by randomized control trials. Clinical significance statementMandibular overdenture assisted by two immediately-loaded unsplinted implants is successful treatment based on 2-year clinical and patient-based outcomes.

Influence of guidance concept in complete dentures on oral health related quality of life – Canine guidance vs. bilateral balanced occlusion

PurposeTo compare the impact of canine guided vs. bilateral balanced occlusion on oral health related quality of life (OHRQoL) as a patient-reported outcome measure. MethodsIn this randomized single-blind crossover trial, 19 patients have been provided with new complete dentures in the maxilla and mandible. OHRQoL was assessed using the 49-item Oral Health Impact Profile (OHIP-49) before the start of the prosthodontic treatment (B), 3 months after insertion of the new dentures (T1), and 3 months after rework into the alternative concept (T2). Multilevel mixed-effect linear regression models were computed to determine the effect provided by the new set of dentures and the specific impact of the occlusal concept on OHRQoL using summary scores of the OHIP-49 and of a 19-items subset specific for edentulous patients (OHIP-EDENT). ResultsAt baseline, participants’ OHRQoL was substantially impaired indicated by an average OHIP-49 score of 42.1 points and an OHIP-EDENT score of 21.1 points. The effect of provision of a new set of complete dentures was a statistically significant decrease of 8.3 points (OHIP-49) and 4.0 points (OHIP-EDENT), respectively, representing a clinically relevant improvement in OHRQoL. When wearing dentures with bilateral balanced occlusion, participants showed on average 1.6 points higher OHIP-49 scores and 0.9 points higher OHIP-EDENT scores compared to canine guided dentures. This effect of the occlusal concept was neither statistically nor clinically significant. ConclusionsBoth investigated occlusal concepts for complete dentures were comparable in their effect on patients’ perceptions with none being considerably superior in terms of OHRQoL.

Dentist-Patient Communication and Denture Quality Associated with Complete Denture Satisfaction Among Taiwanese Elderly Wearers.

The aim of this study was to explore individual (ie, sociodemographic characteristics, patient personality) and clinical factors (ie, dentist-patient communication, denture quality) associated with complete denture satisfaction among the Taiwanese elderly population. A multistage sampling and cross-sectional design was used to collect data. A total of 387 fully edentulous citizens, aged 65 years and older and who had received new sets of complete dentures, were selected. The participants completed clinical dental examinations and questionnaires by personal interview to collect information on denture satisfaction and associated variables. The relationship among three groups of these participants (satisfied, neutral, and dissatisfied) and potential factors were simultaneously examined using polytomous logistic regression analysis. Overall, 36.7% of the participants were dissatisfied with their dentures. Living status (crude odds ratio [COR] = 2.04), personality (COR = 4.86), dentist-patient communication (COR = 7.46), and denture quality (COR = 5.02) were associated with complete denture satisfaction. The multivariate regression model showed that dentist-patient communication (adjusted odds ratio [AOR] = 6.41) and denture quality (AOR = 4.40) were significant complete denture satisfaction factors that diluted the effect of living status and personality. Inadequate dentistpatient communication and low denture quality were associated with the dissatisfaction of patients with dentures. To increase complete denture satisfaction, the importance of training programs aimed at enhancing dentist-patient communication and denture quality cannot be overemphasized.
