To evaluate and compare the effect of diabetes and complete denture wearing on the occurrence of Mucor isolates in edentulous geriatric patients

Objectives: The objective of this study was to explore the impact of diabetes and complete denture use on the presence of Mucor isolates in edentulous geriatric patients. Material and Methods: Intraoral swab samples were collected using a sterile culture device, focusing on the center of the hard palate for all patient groups. Immediately after collection, each sample was immersed in a sterile culture-collecting device containing normal saline to prevent swab drying. Subsequently, these swabs were isolated and cultured in Sabouraud’s dextrose agar medium at a temperature range of 25–30°C. Results: Statistical analysis using the Chi-square test revealed no Mucor isolates in any of the four groups. However, the combination of diabetes and complete denture use led to the isolation of other commensal fungi in 65% of samples, contrasting with the non-diabetic, non-denture-wearing group where this occurrence was only 5%. Conclusion: The study concluded that there was no observable correlation between the occurrence of Mucor isolates in edentulous geriatric patients, irrespective of complete denture use, or diabetic status. Nevertheless, the coexistence of diabetes and complete denture use significantly increased the presence of opportunistic fungi in the oral cavity compared to non-diabetic, non-denture-wearing patients.

Microbiota of complete removable dentures

Purpose: to study the quantitative and qualitative composition of microflora on the surface of complete removable dentures after 1 and 4 years of use. Materials and methods: 40 patients were diagnosed with complete edentulism (K08.1) using complete removable acrylic dentures for no more than 4 years were examined. The composition of the microflora was determined by mass spectrometry method. Statistical processing of the results of the study was carried out using the computer package Statistica13. To assess the differences between the groups, parametric t-criteria with Bonferroni correction were used for multiple comparisons, the critical level of statistical significance of p was 0.05. Results: it was found that in 4 years the number of yeast and fungi increased by 91%, n=20 (100%); the number of actinobacteria increased by 61%, n=20 (100%); the number of gram-negative bacteria increased by 500% n=20 (100%); the number of anaerobic microorganisms increased by 50% n=20 (100%); the number of cocci and bacilli increased by 190% n=20 (100%). Conclusion: after conducting the research, we found that after 4 years of using removable dentures n=20 (100%), the number of cocci and bacilli increased from 56±5 (105 cells/gram) (p=0.03) to 107±8 (105 cells/gram) (p=0.04). The number of anaerobes increased n=20 (100%) from 68±6 (105 cells/gram) (p=0.0002) to 102±9 (105 cells/gram) (p=0.0002). The number of actinobacteria n=20 (100%) increased from 30±3 (105 cells/gram) to 143±12 (105 cells/gram) (p=0.003). The number of gram-negative bacteria n=20 (100%) increased from 4±1 (105 cells/gram) (p=0.0005) to 24±2 (105 cells/gram) (p=0.0006). The number of fungi and yeast n=20 (100%) increased from 977±90 (105 cells/gram) (p=0.0003) to 1587±136 (105 cells/gram) (p=0.003).

Indices for complete dentures after cleaning at home

Background: According to experts, there are more than 350 million fully edentulous patients globally, accounting for 7% of the world population. Edentulous patients require dentures to maintain a good quality of life. Complete dentures need to be cleaned on a regular basis to prevent their microbial contamination and inflammatory complications. Aim: To assess the efficacy of Anolit ANK Super solution for cleaning complete dentures at home. Materials and Methods: The hygiene of complete dentures was assessed using the Ulitovsky–Leontiev index. The efficacy of cleaning complete dentures with Anolit ANK Super solution compared to 0.05% chlorhexidine bigluconate solution was assessed. Moreover, statistical analysis methods were used: normality test; threshold value, or baseline significance level p=0.05; intragroup comparison (6 comparisons) with the Bonferroni correction (critical p=0.0083). Results: When assessing the hygiene of dentures using the Ulitovsky–Leontiev index, the denture cleanliness index (DCI) changed from 4.65 points (poor denture hygiene) to 3.50 points (satisfactory denture hygiene) after one month of using Anolit ANK Super solution. After three months of using Anolit ANK Super solution, the DCI changed from 3.50 points (satisfactory denture hygiene) to 2.60 points (good denture hygiene). After six months of using Anolit ANK Super solution, the DCI changed from 2.60 points (good denture hygiene) to 1.55 points (very good denture hygiene). After one month of using 0.05% chlorhexidine bigluconate solution, the DCI changed from 4.85 points (poor denture hygiene) to 4.40 points (poor denture hygiene) (p=0.0083). After three months of using 0.05% chlorhexidine bigluconate solution, the DCI changed from 4.40 points (poor denture hygiene) to 3.50 points (satisfactory denture hygiene) (p=0.0083). After six months of using 0.05% chlorhexidine bigluconate solution, the DCI changed from 3.50 points (satisfactory denture hygiene) to 2.60 points (good denture hygiene) (p=0.0083). Conclusion: The follow-up revealed that, with similar duration of exposure to test solutions, Anolit ANK Super solution for cleaning dentures at home used for 6 months decreased the DCI threefold from baseline (p=0.000002) and improved denture hygiene from poor to good.

Thirty-Year Clinical Performance of Double-Crown Retained Removable Partial Dentures - A Practice Based Retrospective Study.

This retrospective study evaluated the clinical long-term survival of 1405 double-crown retained removable partial dentures (DRPDs) over 30 years of follow-up. Kaplan Meier survival rate for DRPDs was 96.6% after 5 years, 88.2% after 10 years, 61.7% after 20 years, and 38.3% after 30 years. Survival rates of abutment teeth were 94.3% after 5 years, 80.2% after 10 years, 51% after 20 years, and 27% after 30 years. Key failure risk factors of DRPDs were age, £3 abutment teeth, and complete denture in opposing jaw. Abutment teeth failure risk factors included age, anterior abutment teeth, punctual support, and non-vital teeth.

Conversion of a muco-supported complete prosthesis into fixed implant-supported prosthesis using the NeoConvert™ solution in a maxillary rehabilitation with guided surgery and immediate loading

Modern dentistry has seen the development of different techniques aimed at improving patient satisfaction. Immediate loading and delivering a fixed implant-supported prosthesis at surgery time has become an option. This case report describes the clinical results of the immediate loading of a conventional complete denture converted into a fixed prosthesis on six implants placed under a guided surgery protocol. A male patient, systemically healthy, with total upper edentulism, attended the ILAPEO College to begin treatment with implants in the upper jaw. Six implants were placed under a guided surgery protocol, and then immediate loading was performed by converting the patient’s complete denture into a fixed prosthesis using the NeoConvert™ system. Immediate loading using the NeoConvert™ technique is a functional and predictable alternative, reducing clinical time and achieving great patient and clinician satisfaction.

Analysis of Oral Health-Related Quality of Life in Elderly Romanian Edentulous Patients: Implant-Supported Versus Conventional Complete Dentures

Analysis of Oral Health-Related Quality of Life in Elderly Romanian Edentulous Patients: Implant-Supported Versus Conventional Complete Dentures

Comparison of conventional and digital impression approaches for edentulous maxilla: clinical study.

The expectations for the clinical and laboratory phases of tissue-supported complete dentures (TSCDs) are changing. Currently, there is a trend towards fast, comfortable, reliable, and low-cost methods. In TSCD impressions, simplified impression and digital impression methods involving the use of an intraoral scanner (IOS) are becoming preferable. Given this situation, this study aims to compare different conventional and digital impression methods used in TSCDs. Patients with maxillary complete edentulism and healthy oral mucosa were included in this study. In the digital group, two different impressions were made using an IOS (Trios4) without (D1) and with (D2) artificial intelligence scanning (AI-Scan). In addition, a modified impression (D3) was made using the IOS in two steps, including the occlusal rim. In the conventional group, a two-step impression (C1) using an individual tray with zinc oxide eugenol and a one-step simplified impression (C2) using a stock tray with irreversible hydrocolloid were made. The comparison groups were determined to be C1-C2, C1-D1, D1-D2, and D1-D3. The best-fit algorithm was used to superimpose the impressions to be compared. The right and left vestibular areas, postdam area, palatal area, right and left matching area, entire surface, and borders were evaluated separately. Fifteen patients were included in this study. In the C1-C2 group, the mean deviation at the borders was statistically significant (p = 0.01). No regions in the C1-D1 and D1-D3 groups exhibited significant differences in the mean amount of deviation (p > 0,05). In the D1-D2 group, the mean deviation in the palatal area was significant (p = 0,03). In maxillary edentulism, digital impressions have shown comparable results to conventional impressions, suggesting promising implications for clinical applications. The clinical trial has been registered (ClinicalTrials.gov ID NCT06400277, registration date 06/05/2024, 'retrospectively registered').

Examination of oral health quality of life and patient satisfaction in removable denture wearers with OHIP-14 scale and visual analog scale: a cross-sectional study

BackgroundOral Health-Related Quality of Life (OHRQoL) is a term that encompasses conditions such as oral health status, living conditions, and function. OHQoL can change with the varying health conditions of the same individual. Many patients cannot afford implants or have anatomical limitations and therefore use traditional removable dentures. There are comparatively few studies investigating OHRQoL and denture satisfaction that include the patients’ sociodemographic data, denture satisfaction and related questions.AimThis study aimed to investigate OHRQoL and patients’ satisfaction with three types of dentures: upper and lower complete dentures, upper and lower partial dentures, and upper complete lower partial dentures.MethodsThe study was conducted between January 2022 and June 2023, with 150 patients using removable dentures. Patients’ age, gender, education level, place of residence, smoking status, reasons for tooth loss and visiting the clinic, type of denture and the duration of denture use were recorded. Oral Health Impact Profile (OHIP-14) and patient satisfaction with dentures as measured on a Visual Analog Scale (VAS) were used to assess patients’ satisfactions with OHRQoL and dentures respectively. Descriptive statistics, the Shapiro-Wilk normality test, the Mann-Whitney non‐parametric test and the Kruskal-Wallis test were used.ResultsStatistically significant differences were found between gender, prosthetic type, usage duration and OHIP and VAS scores (p < 0.05). Women’s OHIP scores were higher than men’s, patients using complete dentures had higher scores than those using partial dentures in both jaws, those using dentures for less than 1 year had higher scores than those that had used them for more than 1 year. The analysis revealed no statistically significant differences in OHIP and VAS scores based on age, education level, and place of residence (p > 0.05).ConclusionsPatients may find it easier to adapt to removable partial dentures compared to complete dentures. Therefore, in prosthetic planning, dentists should prioritize preserving existing teeth. Regardless of the type of prosthesis, patients adapt to their prostheses over time, leading to increased satisfaction with prolonged use. Since individuals do not have a habit of visiting the dentist when there is no known problem, dentists should encourage patients to attend regular dental check-ups.

Comparison between patients rehabilitated with full-arch fixed implant-supported prostheses and complete denture regarding well-being, self-esteem and quality of life

Objective: To evaluate and compare satisfaction and OHRQoL in patients using complete dentures or full-arch fixed implant-supported prostheses. Material and Methods: 200 patients were divided into two groups: 1) Test group (TG): patients rehabilitated with lower full-arch fixed implant-supported prosthesis; and 2) Control group - (CG): patients using complete dentures. Patients had Oral Health-related Quality of Life (OHRQoL) assessed through 4 validated questionnaires: 1) Oral Health Impact Profile (OHIP-14); 2) Rosenberg Self-Esteem Scale (RSS); 3) Orthognathic Quality of Life Questionnaire (OQLQ); and 4) Short Form Health Survey (SF-8). Statistical analysis was done by using the Wilcoxon test, considering a level of significance of 5%. Results: The results demonstrated that the TG presented better results (p&lt;0.001) than the CG in relation to OHIP-14 (9.0±2.36 and 21.0+3.17, respectively), including functional limitation, physical pain, physical and psychological disability, and social and physical disability. Moreover, TG presents better outcomes than CG for RSS (35.0+2.31 and 31.0+2.31, respectively) and OQLQ (16.0+3.19 and 27.5+3.22, respectively), but without difference (p = 0.79) for SF-8 (83.1+6.64 and 83.1+8.16, respectively). Conclusion: Patients with lower full-arch fixed implant-supported prostheses, compared to patients using complete dentures, present a better perception regarding their general well-being, higher self-esteem and quality of life.

Natural products for denture base disinfection: A scoping review.

This study aims to map the existing literature on natural products used as disinfection substances for conventional polymethyl methacrylate (PMMA) and computer-aided design and manufacturing (CAD-CAM) dentures. Denture wearers are at high risk for denture stomatitis. Natural products have attracted the interest of the scientific community as an alternative to synthetic ones. The guiding question "Which natural products have been applied to disinfect complete dentures in conventional PMMA or CAD-CAM PMMA resin?" Searches were conducted in the PubMed/MEDLINE, Embase, Web of Science, and Cochrane databases, and manual searches were performed in reference journals in the area with studies published until December 2023, without language or date restrictions. A total of 4272 articles were identified, and 46 studies were included after applying the eligibility criteria. Thirty-nine natural products were evaluated. Of the included studies, 43 presented positive findings and three obtained negative findings on the effectiveness of natural products in inhibiting or killing Candida albicans. Natural products, predominantly sourced from the Plantae kingdom, have demonstrated efficacy in reducing Candida albicans on the surface of conventional PMMA. However, the evidence primarily stems from invitro studies, underscoring the necessity for additional clinical research to validate their applicability under real microbiological conditions in prosthesis users.

Complications and Patient Satisfaction in Fully Edentulous Patients Treated with a Digital and Conventional Complete Denture, A Cross-Over Clinical Study.

The objective of this clinical study was to evaluate comfort, satisfaction, chewing ability and complications with digital complete dentures (DCD) and conventional complete dentures (CCD). For 16 edentulous patients, two sets of upper and lower dentures were fabricated by students in a university dental clinic. The impression for the DCD was done using indirect scanning of the cast. When the patients were pain free, each set of dentures was worn for four weeks. OHIP-14 and a DSI (Denture Satisfaction Index)were used to measure patient satisfaction and chewing ability respectively. Both questionnaires were administered before fabrication and after wearing each set. Adjustments made during the follow up period were included. At the end of the study, patients could express which set of dentures they preferred. The 25 dental students involved in fabricating the dentures, were questioned in terms of discomfort, preference and future use for both techniques. OHIP-14 showed significantly higher scores for the DCD for the domain concerning psychological discomfort. DSI showed no significant difference for both sets of dentures. In terms of complications, a significant difference was found for occlusion. The DCD required more occlusal adjustments. A minority of the patients (37.5%) chose the DCD as their favourite set. The students preferred the wax try-in and workflow of the CCD. The CCD and DCD showed differences in patient satisfaction. Chewing ability was comparable for both sets of dentures. More occlusal complications were seen in the DCD. Both students and patients preferred the CCD.

Comparison of masticatory performance and oral hygiene status using cream-type denture adhesives and home liners: A cross-sectional study using propensity-score matching.

Differences in the effects of cream-type denture adhesives and home liners remain unclear. This cross-sectional study aimed to clarify the differences in the oral-hygiene status and masticatory performance between participants using cream-type denture adhesives and those using home liners. Masticatory performance with and without cream-type denture adhesives and home liners was evaluated using colour-changeable chewing gum. Oral hygiene was assessed using the tongue coating index (TCI). Propensity-score matching was performed using oral moisture, presence of palatal or mandibular protuberances, type of residual ridge, denture type (complete or partial denture), and denture retention as background factors. Wilcoxon signed-rank test was used to examine the differences in masticatory performance with and without cream-type denture adhesives and home liners and differences in masticatory performance and TCI between the cream-type denture adhesive and home-liner groups. This study included 38 and 40 cream-type adhesive and home-liner users, respectively, and 17 pairs were obtained after propensity-score matching. The Wilcoxon signed-rank tests showed that masticatory performance was significantly different with and without the use of home liners, and higher values were obtained with the use of home-liners. However, the cream-type denture adhesive and home-liner groups showed no significant differences in terms of the change in masticatory performance with the use of them. Furthermore, Wilcoxon signed-rank tests showed that TCI values were significantly high in the cream-type adhesive group. The findings in this study suggest that home liners improve masticatory performance and that participants regularly using cream-type denture adhesives have poorer oral hygiene.

A comparison between the flexural strength of milled, conventional, and carbon fiber PMMA for interim implant supported fixed complete dentures: An In vitro study

Objectives: to investigate the flexural strength of three materials commonly used for interim implant-supported fixed complete dentures (ISFCDs): conventional heat cure PMMA, CAD/CAM milled PMMA, and carbon fiber-reinforced PMMA. Methods: Sixty specimens (n=60) divided equally into three groups (heat cure, milled, carbon fiber) were prepared. Samples were inspected to ensure absence of voids or irregularities and when required, minor adjustments were made to adjust the dimensions. The samples underwent thermocycling (5-55°C for 2500 cycles) and were then tested using a three-point bend test. Results: There was a statistically significant difference between heat cure PMMA and carbon fiber PMMA (p&lt;0.001), between CAD-CAM resin and carbon fiber resin (p&lt;0.001). There was no significant difference between CAD-CAM and conventional PMMA resin (p&gt;0.05). Conclusions: as clinical implications, using carbon fiber is a viable treatment option for interim ISFCDs. Veneering the material with pink and white resin would improve the overall esthetics.

Magnetically coupled tooth arrangement for an implant-supported fixed complete denture: A dental technique

Magnets have been used to help position dental components, including magnetic mounting plates for articulators and magnetic attachments for implant surgical guides. A magnetically coupled tooth arrangement technique used the fixed reference point of integrated implants to determine maxillomandibular relations and the tooth arrangement, thus improving the efficiency of the clinical appointment. The magnetic framework was screwed into the implants only once for the duration of a clinical appointment. The base was used to complete the tooth arrangement and determine the maxillomandibular jaw relationship.

Accuracy of repaired maxillary dentures from two different repairing techniques: In vitro study

BackgroundDenture fracture is a common problem with acrylic dentures. The fractured denture can be repaired using various techniques such as self-cure acrylic resin acrylic resin and fiber-reinforced acrylic resin. PurposeThe purpose of this study was to compare the accuracy of dentures repaired with self-cure acrylic resin and fiber-reinforced acrylic resin processed using two different techniques (long-cure and microwave processing). Materials and methodsA total of 20 maxillary complete dentures were processed with two techniques; heat (long cycle) processing (10 dentures) and microwave processing (10 dentures). The maxillary cast and denture surface were scanned with Medit intraoral (Medit i700, Medit, South Korea) and STL files were created. Then, the dentures were sectioned at the midline and repaired using self-cure acrylic resin and fiber-reinforced acrylic resin and scanned with Medit intraoral. Finally, adaptation deviations were analyzed from computer software (Geomagic Control X, 3D Systems Inc., USA). The adaptation deviations in each group (long cure and microwave) were compared using an Independent T-test. Two-way ANOVA was done to see whether curing techniques and repairing methods affect the accuracy of repair. A P-value of 0.05 was considered significant. ResultsThe adaptation deviation was slightly higher in the fiber-reinforced acrylic resin group (0.565 ± 0.093) than in the self-cure acrylic resin group (0.536 ± 0.066). However, there was no statistical difference in the adaptation deviations of repaired dentures with self-cure acrylic resin and fiber-reinforced acrylic resin in the long-curing (P-value 0.245) and the microwave (P-value 0.638). Similarly, the adaptation deviation was slightly higher in the long-curing group (0.577 ± 0.075) than in the microwave group (0.524 ± 0.079). However, there was a statistically significant difference in the adaptation deviation of repaired dentures between long-curing and microwave techniques with self-cure acrylic resin (P-value 0.016) but no difference in fiber-reinforced acrylic resin (P-value 0.127). The result of Two-way ANOVA shows that there is no statistically significant interaction between curing techniques (long curing and microwave) and repairing methods (self-cure acrylic resin and fiber-reinforced acrylic resin) for adaptation deviations (P-value 0.646). However, the curing techniques show statistically significant differences (P-value 0.039). ConclusionAcrylic dentures can be repaired with self-cure resin or fiber-reinforced self-cure resin using various processing methods. The accuracy of the denture after repair is unaffected by the repairing method (self-cure acrylic resin and fiber-reinforced acrylic resin) but the accuracy of the denture after repair is affected by the curing techniques (long-curing and microwave). In self-cure resin, the microwave processing showed higher adaptation deviation and less accuracy, whereas the long-curing processing showed lower adaptation deviation and high accuracy.

АНАЛИЗ КАЧЕСТВА ПОЛИМЕРИЗАЦИИ БАЗИСНЫХ ПЛАСТМАСС

The issue of restoring dental defects is relevant for modern dentistry. Restoration of the functions of the dental system is possible by partial or complete removable laminar dentures which basis is made of lamellar plastics in the most cases. It is necessary to strictly observe the temperature regime of polymerization of plastics, since structural defects in the material can form, causing complications after prosthetics. There are devices for automatic polymerization with a temperature control function, but the most common is the classical method (in a water bath) of making denture bases. Purpose of the study: compare the quality of polymerization of base plastics using the classical method and using modern equipment. Materials and methods: 8 plastic samples were made, 50% of which were polymerized using the classical method, and the other half using an apparatus for hot polymerization of plastic. An external inspection of the samples was carried out and the finishing time of the plates was estimated. After polishing, the samples were examined using an electron microscope. Results and discussion: samples, polymerized using the classical method showed signs of granular porosity, the polishing time was 8 minutes 13 seconds; electron microscopy results revealed the presence of defects, which could lead to complications. Plates polymerized by the instrumental method are homogeneous, polishing time is on average 4 minutes 42 seconds. When these plates were examined with an electron microscope, there were minor defects. Conclusion: it is recommended to polymerize base plastics using devices for hot polymerization of plastics in order to prevent complications from using removable dentures.

O-Ring and Bar-Clip: A Comparative Analysis of Retention in Overdenture Prostheses - A Systematic Review.

Mandibular implant-supported overdentures (IODs) show higher retention than conventional complete dentures. However, there is no consensus on the best attachment to ensure resistance to vertical displacement. The most used are o-ring and bar-clip. This systematic review answered "Which type of attachment for overdenture prosthesis provides higher retention: o-ring or bar-clip? The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was followed and registered in the International Prospective Register of Systematic Reviews (PROSPERO). The search was applied to 5 databases and grey literature. The selection process occurred in two blinded steps by the reviewers following the eligibility criteria: a randomized clinical trial comparing retention between o-ring and bar-clip in IODs. The risk of bias was analyzed by RoB II. 206 articles were found, and after removing the duplicates 136 were evaluated by title and abstract of which 24 were selected for full reading, 5 met the eligibility criteria, and all had a high risk of bias. The bar-clip provided higher retention than o-ring in four studies. The bar-clip system provides a higher retention rate than the o-ring. In addition, the selection of attachment systems is dependent on the patient's anatomical-functional and economic conditions.

Comparison of denture space and patient satisfaction for neutral zone versus standard-designed digital dentures restoring mandibular resorbed ridges: A crossover randomized clinical trial.

To compare neutral-zone-designed and standard-designed digital complete dentures used to restore severely resorbed ridges through differential digital analysis of teeth arrangement position, shape of the polished surface, and assessment of patient satisfaction. This study applied a within-subject comparison of two denture forms: computer-aided design and computer-aided manufacturing (CAD-CAM) dentures designed based on the bone-support concept (control group) and CAD-CAM dentures designed based on the neutral-zone concept (test group). Twelve completely edentulous patients exhibiting advanced ridge atrophy were recruited, and they were randomly assigned to use one of the two dentures before the other. A comparison between the two groups' virtual denture confines was conducted using "Medit compare" digital software. The average values of three-dimensional deviations between the two dentures at different regions were calculated. The "patient denture assessment" questionnaire was used to gauge participants' satisfaction with their dentures. The obtained scores were used to compare the two denture types. The position of the neutral zone was significantly shifted at the level of both denture teeth and denture base outer limits (p = 0.001). The greatest deviation was calculated at the region of the palatal polished surface followed by lingual flange contours, while the buccal flanges displayed the least deviations (p≤0.05). Statistically significant differences were observed between patients' satisfaction with neutral zone and standard dentures regarding function and comfort, retention, and stability of lower dentures (p≤0.05). CAD-CAM neutral-zone dentures have distinctly different anatomical confines that can be clinically correlated to their better impact on patient acceptance.

Comparative Analysis of Adaptation of Conventional and Printable Complete Denture Bases to the Underlying Casts - An In Vitro Stereomicroscopic Study.

Properly adapted complete denture bases will have adequate retention to the underlying oral mucosa. With technological advancement, there are various techniques of fabrication of complete dentures. There are studies regarding the marginal adaptation of conventional and CAD-CAM denture bases, but there is not enough research comparing the marginal adaptation and polymerisation shrinkage of conventional and 3D printed complete denture bases. In vitro study using stereomicroscopy to determine the marginal discrepancy between the denture base and the cast. Twelve gypsum casts were taken and divided into conventional and 3D-printed groups. Conventional denture bases were fabricated by adapting wax of 2 mm thickness which was subsequently processed whereas 3D printed bases were designed and the standard tessellation language (STL) files were used to print the denture bases. Three points were marked at the mid-palatal line and on both maxillary tuberosities. Digital images were then captured at the marked regions and were used to measure the maximum gap between the cast and denture base at the marked regions. Data were analysed using an independent t-test and one-way ANOVA. Conventional dentures had a significantly lesser marginal discrepancy than 3D printed dentures (P = 0.000). The left maxillary tuberosity showed the highest marginal discrepancy, significantly different from mid-palatal and right tuberosity sites. Conventional dentures perform better than their counterparts in terms of adaptation. This accurate adaptation is vital for the retention of the complete denture.

Analyzing The Correlation Between The Conventional Complete Denture Occlusal Contact Points And Patient’s Satisfaction

Background: Conventional complete dentures continue to be a vital and essential method for restoring oral function in edentulous adults. However the quality of complete dentures influences the satisfaction level, thereby improves the psychological wellbeing of dentulous adults. Aim: A prospective in vivo study aims to analyse the presence of conventional complete denture occlusal contact points significantly influence patients' satisfaction levels. Materials and methods: Thirty patients who had received complete dentures were evaluated for their occlusal contact points one the day of insertion and 2 weeks later. Patient satisfaction questionnaire, which included subjective parameters such as initial adaptability, post insertion problems, aesthetics, masticatory ability, speech, retention was conducted at day 1 (day of insertion) and 2 weeks later. Results: Number of contact points almost were same on day 1 and 2 weeks later. The overall satisfaction of the patient has improved during the time interval. But correlation of the occlusal contact points to the patient satisfaction has no statistically significant value. Conclusion: Therefore, the overall satisfaction of the patient increased while using the complete denture from 1st day of denture insertion and after 14 days irrespective of number of contact points in the conventional complete denture with same occlusal scheme
