Impact of occlusal schemes on prognosis of conventional complete dentures in patients with severely resorbed alveolar ridges

Bilateral Balanced Occlusion (BBO) and Canine Guidance (CG) are occlusal schemes that have been successfully used in complete dentures (CDs). The objective of this study was to evaluate the effects of CG compared to BBO on satisfaction, oral health-related quality of life (OHRQoL) and masticatory performance in CDs wearers with severe resorbed alveolar ridge by means of a crossover trial. Sixteen edentulous patients with severe resorbed ridges were treated with new maxillary and mandibular CDs. After adaptation period, they were randomly divided into two groups according to a sequence of occlusal schemes: BBO for 30 days followed by CG for 30 days or, CG for 30 days followed by BBO for 30 days. Patient satisfaction with their dentures, OHRQoL and masticatory performance were assessed immediately 30 days after of using each occlusal scheme. The results of satisfaction and quality of life were using Wilcoxon test, and data regarding masticatory performance were analyzed through paired t-test (α = .05). The occlusal scheme used in complete dentures had no significant influence on general patient satisfaction (p = 0.06), overall quality of life (p = 0.09), or masticatory performance of patients (p = 0.182). Both BBO and CG can be considered as suitable for oral rehabilitation with CDs in patients with severe resorbed alveolar ridges. However, CG may be considered as a scheme of choice by clinicians due to its greater simplicity and shorter execution time.

Analysis of modified palatal surface for better speech in edentulous patients: A clinico-analytical study.

Phonetics with mechanics and aesthetics are considered cardinal factors contributing to the success of complete dentures. The aim of the current study was to evaluate the changes in speech in complete denture patients with and without palatal surface changes. The data collected for the study involved completely edentulous Patients (n= 80). Patients were divided into two groups. Group A: Up to 50 years (n= 40); Group B: Above 50 years (n= 40) (including male and female). Each group was further divided into four subgroups for speech analysis-without dentures (A1/B1); with conventional dentures (A2/B2); dentures with a palatogram (A3/B3) and dentures with palate sandblasted (A4/B4). The speech sounds of all patients were evaluated for pitch and intensity using a spectrophotogram (Praat software) and Likert scale. The data so obtained from the quantitative and qualitative analysis were statistically analysed through one-way ANOVA, unpaired student's t-test, and Pearson correlation coefficient. Qualitative analysis was done with the Mann-Whitney U test. The maximum mean value of the pitch and intensity in Groups A and B was subgroup A3 (Palatogram) 190.37 ± 21.50 and 77.07 ± 7.58, B3 (Palatogram) 190.87 ± 24.36 and 75.33 ± 8.12. When comparing Groups A [A1, A2, A3, A4] and B [B1, B2, B3, B4] on the basis of pitch and intensity, a statistically insignificant value was found. No changes in speech sounds (pitch and intensity) were observed in terms of age. Both quantitative and qualitative analysis results showed that speech sounds in the patients with palatogram, had the highest pitch and intensity and were most clear to the listener and there were statistically significant differences from other groups. Speech was better in palatogram-based dentures in comparison to a sandblasted denture, conventional denture and without denture in terms of qualitative and quantitative analysis. The physiologic nature of the palatogram fabrication technique produces the palatal part of the denture more compatible with the tongue, thus producing better speech.

Evaluation of Awareness Toward Various Treatment Options and Maintenance Practices among Removable Partial and Complete Denture Patients in Western Maharashtra – A Questionnaire-Based Study

ABSTRACT Introduction: Researchers must concentrate their focus on whether patients understand various treatment options available among removable complete and partial denture patients and whether they are aware of the maintenance protocol of the prosthesis Materials and Methods: All the patients who completed removable partial or complete denture treatment in a period of 6 months were included in the study. Collected data were statistically analyzed using Chi-square test at a significance level of P < 0.05. Results: Awareness needs to be increased regarding the treatment options available for removable complete and partial denture treatment causes because many subjects in this study were only aware of the removable partial denture and complete denture treatment for missing teeth and not the other options, especially among individuals in the lower socioeconomic group Conclusion: The findings indicate that awareness needs to be increased regarding the functions of prostheses such as esthetics and phonetics because many subjects in this study were only aware of the masticatory function performed by prosthesis.

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.

Comparative Evaluation of Masticatory Efficiency in Various Facial Forms of Dentate and Rehabilitated Complete Denture Patients.

To evaluate the masticatory efficiency of dentate and rehabilitated complete denture patients in various facial forms. A total of 60 subjects were selected for the study; 30 subjects belonged to the dentate group (D Group) and 30 subjects belonged to the completely edentulous group rehabilitated with conventional complete dentures (CECD Group). All patients were divided into a subgroup (brachyfacial, mesofacial, and dolichofacial facial forms) using facial index measurement and cephalometric analysis. After the subjects were divided into groups, masticatory efficiency testing was performed with spectrophotometric analysis using diluted expectorate of chewed natural beetroot test food (10, 15, and 20 strokes). The mean absorbance value was considered as the mean masticatory efficiency from which the average masticatory efficiency percentage was determined using a masticatory efficiency percentage equation and considered as the masticatory efficiency of that particular subject. Statistical analysis revealed that in the D Group, brachyfacial subjects exhibited the highest masticatory efficiency (70.9 ± 12.64%), followed by mesofacial (60.6% ± 10.66%) and dolichofacial (34.3% ± 10.81%) subjects. In the CECD groups, the results for brachyfacial were highest (52.7% ± 8.11%), followed by the mesofacial (42.3% ± 6.52%), and dolichofacial (29.3% ± 7.76%) subjects. Along with other determinant factors, facial form plays an influential role on masticatory efficiency. Brachyfacial subjects exhibited the highest masticatory efficiency, followed by mesofacial and dolichofacial subjects in both study groups.

EVALUATION OF TRAUMATIC ULCERATIONS FREQUENCY AND SITE IN POST-INSERTION ADJUSTMENT RECALL VISITS IN COMPLETE DENTURE PATIENTS VISITING A DENTAL COLLEGE IN CHITWAN

Background: During the initial days after complete denture insertion, patients can face various difficulties like traumatic ulcerations, loss of retention, unstable denture, difficulty in mastication and speech etc. The aim of the study was to assess the site and number of traumatic ulcerations in maxillary and mandibular denture bearing area in post-insertion adjustment recall visits and also to find out the total number of adjustments recall visits required until the patients become comfortable with the denture. Methods: A cross-sectional study was conducted among 75 complete denture patients to look for the number and site of traumatic ulcerations and the number of post-insertion recall visits required until they became symptom free. Descriptive (frequency and percentage) statistical analysis was done using SPSS Statistical Software Package (version 21.0). Results: In the mandibular arch 49.33% (N=34) and in the maxillary arch 12.5% (N=9) patients required adjustment visits for traumatic ulcerations. In the first recall visit after 24 hrs, 34 patients showed traumatic ulcerations on mandibular arch while only 6 patients experienced traumatic ulcerations on the maxillary arch. Conclusions: The patients required more post insertion adjustments for traumatic ulcerations in the mandibular arch in comparison to maxillary arch. Traumatic ulcerations was most frequently found in distobuccal sulcus area in the maxillary arch and labial sulcus in the mandibular arch.

Clinical Efficacy of Two Denture Adhesives Among Complete Denture Patients: A Cross-over Randomized Clinical Trial

Aims and objectives: The clinical efficacy of different forms of denture adhesives have been inconsistent among studies with unclear differences among them. The aim of this study is to evaluate the masticatory efficiency and satisfaction of complete denture wearers without and with the use of two different forms of commercially available denture adhesives.
 Material and Methods: 30 edentulous participants with new complete dentures placed one month before the commencement of the study were included in this cross-over randomized clinical trial (CTRI/2021/07/035238) which compared a powder adhesive and a cream adhesive along with no adhesive use. The objective assessment used the Edlund and Lamm index for masticatory efficiency and the subjective assessment followed a specially designed questionnaire. Both assessments were carried out on days 0,7 and 21. One-way ANOVA was used to compare the objective data and the questionnaire responses were obtained as percentages.
 Results: The one-way ANOVA test for difference between the groups was statistically insignificant for all layers (P>.05). The questionnaire responses revealed that 53.3% of the participants preferred the use of cream adhesive over powder adhesive.
 Conclusions: No significant difference in the masticatory efficiency was noted between the two denture adhesives and without adhesive use. Patient satisfaction was greater with adhesive use showing a predilection towards cream adhesive due to its longer duration of action and improved chewing ability.

The impact of residual ridge morphology on the masticatory performance of complete denture wearers

Statement of the problemMorphology of the residual ridge (RR) is expected to influence the masticatory performance (MP) of complete denture (CD) patients, but considerable details of this relationship are unknown. PurposeWe aimed to investigate the association between the objective MP and RR morphology of CD wearers and other contributory factors affecting their MP. Materials and methodsSixty-five patients with well-fitting upper and lower CDs with no complaints of pain were enrolled. The objective MP was measured using test gummy jelly and a fully automated measuring device. The RR form was divided into U-type, V-type, I-intermediate, and F-Flat, then combinations of upper and lower RR forms (combined RR) were classified. The height was measured using CD's denture basal surface replicas, while occlusal contact of CDs was assessed using a tooth contact analysis system. The relationship between surveyed factors and MP was evaluated using Spearman's rank correlation, Kruskal-Wallis test, generalized linear regression, and analysis of covariance. ResultsParticipants with F–F and V–F combined RR forms had the lowest MP, while those with U–U and U–I forms had the highest MP, regardless of RR height. Participants with low RR height had the lowest MP, and those with high RR height had the highest MP, regardless of RR form. The analysis of covariance revealed that mandibular RR height, combined RR forms, and total occlusal contact area significantly affected the MP. ConclusionsOur findings confirmed that the mandibular RR height, RR form combinations, and occlusal contact influence the MP of CD wearers.ClinicalImplications:The MP of CD wearers varied, depending on the height and form of the RR, as well as the occlusal contact area of the CDs. The results of this manuscript show that the morphology of the denture bearing area and the occlusion of the CDs are essential factors in predicting the treatment outcome of CD wearers. This allows the clinician to fabricate a complete denture with the denture basal surfaces adjusted and occlusion provided according to the patient. CD patients can be educated on how to chew to improve MP based on their own RR morphology.

Detection of Actinobacillus actinomycetemcomitans DNA in Patients with Partial and Complete Dentures by Real-Time PCR

Background: The purpose of the present study was to detect Actinobacillus actinomycetemcomitans (Aa) using RT-PCR in patients with complete and partial edentulism before (T0) and three months after (T3) treatment with removable partial dentures (RPD) and complete dentures (CD), respectively, to compare the data between these two research groups. Methods and Results: The sample comprised 60 patients: 33 men and 27 women, aged 48 to 76 years. The patients were divided into two groups. Group 1 included 30 patients with partial edentulism who were treated with RPD. Group 2 included 30 patients with complete edentulism who were treated with CD. The samples from Group 1 were taken from the gingival sulcus of the abutment teeth by means of sterile paper points. For Group 2, the samples were taken with a sterile swab from the dorsum of the tongue. The samples were taken in T0 and T3 intervals. To detect Aa DNA, we used RT-PCR and ParodontoScreen REAL-TIME PCR Detection Kit (DNA-TECHNOLOGY). Bacterial load levels of species were conventionally represented in logarithm (Lg) of genome equivalents per sample. The results were also presented in three ranges depending on the level of bacterial load: normal (< 4.0Lg), light/moderate (≥4.0 Lg), and severe (>5.0 Lg). The study found a significant difference in the amount of Aa between the T0 and T3 intervals only in patients treated with RPD (0.871.58 Lg vs. 1.28 1.96 Lg, P=0.004). Patients treated with CD, however, did not differ significantly in the amount of Aa between the T0 and T3 intervals (0.030.16 Lg vs. 0). The average bacterial load in patients with RPD was significantly higher than in those with CD three months after treatment (P=0.02) (Table 2). The range of bacterial load levels in the groups is presented in Table 3. Of the 30 patients with RPD, 2(6.7%) had a severe range, 2(6.7%) had a mild/moderate range, and 26(86.7%) had a normal range. The 30 CD patients all had a normal range. There was no significant difference in the prevalence range of bacterial load level with Aa between groups (Fisher's Exact Test = 3.537, P=0.113) / Monte Carlo Sig. (2-sided) / 0.105–0.121). However, in general, RPD causes a significant increase in Aa, so the level of periodontal pathogens may be higher in RPD patients than in CD patients.

Comparative evaluation of hemispheric and masticatory laterality in complete dentures with two occlusal schemes - A prospective cohort study.

The lateralization can influence the choice of occlusion scheme, patient comfort and success of the prosthesis. The existence of favored masticatory side in complete denture patients and its influence with various occlusal schemes is less analyzed in the literature. The study objective was to compare the masticatory and hemispheric laterality in complete denture subjects rehabilitated with 2 different occlusal schemes at different time intervals. The cohort study recruited 26 patients in each group of balanced and non-balanced occlusion with definitive criteria. Conventional procedures were followed in denture fabrication. The hemispheric and masticatory laterality for all participants were established at 0,1,3- and 6-month intervals. The laterality was categorized as preferred chewing side (CPCS), predominant preferred chewing side (PPCS) and observed preferred chewing side (OPCS). The data on chewing side preference was analyzed by chi square test. (α=0.05). Right side preference was predominant in 86.1% of non-balanced and 60.1% of balanced occlusion participants. The side preference among the 2 laterality and across time interval decreased in masticatory laterality of balanced occlusion participants (P<.05) when compared to non-balanced occlusion. (P>.05). The balanced occlusion dentures had lesser masticatory side preference when compared to non-balanced occlusion complete denture.

Masticatory muscle activity in complete denture wearers: a surface electromyographic analysis

The investigation of the adaptation process to a new denture is relevant to understand the control of muscles. Surface electromyography provide reproducible data of masticatory muscle function and helps to assess the performance of dentures. This longitudinal study simultaneously evaluated electric potential in masseter and anterior temporalis during clenching at maximum intercuspation position and mastication at 2 months after denture insertion and one year later was done in complete denture patients. The surface electrodes were placed in anterior temporalis and ma-sseter region of 22 patients during maximum voluntary clenching and chewing. Statistical analysis was performed by paired t-test. A significant increase in electrical activity was found during clenching and chewing after one year compared to two months. The overall mean EMG value of masseter was significantly higher during chewing at 2 months (p&lt;0.001) and 1 year (p&lt;0.001). A negative correlation was found with respect to age and EMG value of ma-sseter. It is concluded that the electrical activity presented statistically significant difference after one year indicating improved functional quality. A good rehabilitation improves the efficiency of muscles. Monitoring the effect of rehabili-tation on stomatognathic system help to preventively warn about dysfunctions and treatment modifications needed.

Evaluation of red-complex bacteria loads in complete denture patients: a pilot study

ObjectiveThis pilot study aimed to evaluate red-complex bacteria (RCB) loads in edentulous patients, before and after dentures’ insertion.Materials and methodsThirty patients were included in the study. Deoxyribonucleic acid (DNA) isolated from bacterial samples were obtained from the dorsum of the tongue before and 3 months after complete dentures (CDs) insertion in order to identify the presence of RCB (Tannerella forsythia, Porphyromonas gingivalis, and Treponema denticola) and quantify their loads, using real-time polymerase chain reaction (RT-PCR). Bacterial loads were represented as “Lg (genome equivalents/sample)” and the data classified according to the “ParodontoScreen” test.ResultsSignificant changes in bacterial loads were observed before and 3 months after the CDs insertion for: P. gingivalis (0.40 ± 0.90 vs 1.29 ± 1.64, p = 0.0007), T. forsythia (0.36 ±0.94 vs 0.87 ± 1.45, p = 0.005), and T. denticola (0.11 ± 0.41 vs 0.33 ± 0.75, p = 0.03). Before the CDs insertion, all patients had a normal bacterial prevalence range (100%) for all analyzed bacteria. Three months after the insertion, 2 (6.7%) of them had a moderate bacterial prevalence range for P. gingivalis, while 28 (93.3%) had a normal bacterial prevalence range.ConclusionThe use of CDs has a significant impact on increasing RCB loads in edentulous patients.

To Study the Effect of Anterior Palatal Surface Modifications of Complete Denture on Speech Intelligibility Oral Perception and Cortical Brain Function Activity: An In Vivo Study.

The classic maxillary full denture covers the whole palate,preventing the tongue from touching the denture base tissues itself.Thus, it has deleterious effects on cortical brain function and the ability to understand spoken language. This study aimed to determinethe effect of anterior palatal surface modifications of the complete denture on speech intelligibility oral perception and cortical brain function activity. This study compared the speech clarity, oral discernment, and cortical mind capability activity of complete denture wearers in three study groups: a)complete denture wearers with a small opening (SO) in the maxillary front palatal base; b) complete denture patients who wear regular complete denture; c) complete denture patients who did not wear complete denture; and d) complete denture patients who wear a functionally contoured modified palate(FCMP). Patients with no teeth at all underwent four phases of testing to assess their cognitive abilities and speech quality (pitch and volume). In the first phase, partial dentures were used. During phase 2, a conventional full denture was inserted.In the third phase, a palatal base denture was functionally altered. In phase 4, dentures with a little aperture at the front of the palatal base were used. Results:The values of pitch and intensity of sound in category A with FCMP modification I were 180.76 ± 24.12 and 73.27 ± 9.74,respectively. On the other hand, the values of pitch and intensity of sound in category B with FCMP modification I were 185.41 ± 27.29and 73.91 ± 8.31, respectively. The values of pitch and intensity of sound in category A with SO modification II were 188.52 ± 21.11 and 76.13 ± 5.21, respectively. On the other hand, the values of pitch and intensity of sound in category B with SO modification II were 194.59 ± 24.02and 75.21 ± 6.12, respectively. The findings for values of pitch and intensity were statistically significant among the four phases (p < 0.001). The highest speech intelligibility and cortical brain function were observed in phase 4 in both categories A and B, with the highest scores by experts of 3.21 and 3.42, respectively. Conclusion:Based on the findings of this in vivo investigation, it can be concluded that using modified dentures (modification types I and II) following denture installation improves speech intelligibility, oral perception, and cortical brain function activity.

Exploratory analysis of demographic data, tobacco habits, and oral health-related quality of life among complete denture patients.

The present study assessed the impact of demographics and tobacco habits on oral health related quality of life (OHRQoL) among complete denture patients. Prospective cohort study design. Two hundred and eighty four edentulous patients, aged above 30 years, were chosen as the sample for the study after taking informed consent. Information regarding demographic data and smoking status was obtained from each participant. OHRQoL was evaluated using the Oral Health Impact Profile Edentulousness (OHIP EDENT) quantifying various domains, namely functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap. Data were analyzed using the Statistical Package for the Social Sciences version 23.0 (IBM; Chicago, Illinois, USA). Mann-Whitney U test was applied to find significant differences in OHRQoL between gender, age, and smoking status. P < 0.05 was considered to be statistically significant. It was seen that complete denture wearers above 65 years had higher OHIP EDENT scores as compared to younger counterparts suggesting the compromised quality of life in the functional domain which was statistically significant. Psychological discomfort was greater in females while physical disability seemed higher in males. Smoking was found to be a factor associated with decreased OHRQoL. Older age groups, female gender, and smoking were factors associated with decreased OHRQoL among complete denture patients.

Association between Prosthesis Cleanliness and Patient’s Knowledge on Hygiene Habits among Complete Denture Patients and Partial Denture Prostheses Wearers

Introduction: To have good oral health of patients wearing denture they must maintain high standards of both oral hygiene and denture hygiene. The aim of this study was to access the level of knowledge on hygiene and prosthesis cleanliness among elderly individuals wearing removable dental prostheses. Methods: The sample consists of 382 patients visiting the Dental Outpatient Department of Dhulikhel Hospital for a period of 3 months. The oral examination was conducted using basic diagnostic tools (Mouth mirror, periodontal probe and explorer). A prepared questionnaire was developed regarding oral hygiene habits and also the cleanliness of the removable dental prosthesis and was classified according to the 3-point scoring system for all the subjects. Results: A total of 115 (67.3%) and 63(66.3%) patients above age 50 had kept their prosthesis extremely dirty and dirty in CD and RPD wearers. Patients with low education level had kept their prosthesis extremely dirty [109(73.6%) in CD wearers] and dirty [36(63.2 %) in RPD wearers]. 45(72.6 %) patients wearing RPD at night and 102(75.6 %) patients wearing CD at night had dirty and extremely dirty prosthesis respectively. Factors like age, education, duration of wearing prosthesis, prosthesis worn during night time were associated with prosthesis cleanliness. Similarly, instructions for cleaning prosthesis, method of cleaning and frequency of cleaning had significant association with prosthesis cleanliness. Conclusion: Prosthesis cleanliness was affected by age and education level. Most of the patients were uninformed about the good oral hygiene practices. More information should be provided to the patients for raising the awareness and motivating them in cleaning the denture in order to provide cleaner prosthesis.

Assessment of differences in stress markers of edentulous patients rehabilitated with complete dentures

BackgroundBiomarkers can aid in determining the success of complete denture. Fewer studies evaluated the biomarkers in edentulous patients. This can aid in planning of better qualitative care for edentulous patients. The study compared the quantities of nitric oxide (NO), salivary alpha amylase (SAA) and thiobarbituric acid reactive substances (TBARS) before and after denture insertion in complete denture patients. MethodsThe study involved 25 edentulous patients. The saliva samples were obtained from patients prior, 1 h, and 1 week after denture insertion. Standardized procedure was followed in sample management, transportation and storing. The investigations varied with the biomarkers. SAA was estimated by enzymatic assay. TBARS by lipid peroxidation and NO was assessed by Griess reaction. The obtained data were tabled and statistically analyzed. ResultsThe results displayed variation in the level of markers between before and after denture insertion. The mean levels of SAA decreased from 8.26 ± 1.32 nm/ml to 3.44 ± 1.25 nm/ml in following denture insertion. The mean of TBARS and NO increased after denture insertion to 14.33 ± 4.72 nm/ml and NO 22.92 ± 5.79 ng/ml. The results were statistically significant with p < 0.05. ConclusionThe study concluded that denture insertion decreased the levels of psychological stress marker (SAA) and increased the Oxidative stress marker (TBARS, NO).
