Intra Oral Mucosal Conditions in Older Patients With and Without Complete Dentures: A Cross-sectional Study.

Objectives: To obtain baseline information on Oral Mucosal Conditions (OMCs) and its relation to age, sex, medical history and the use of complete denture in a sample of edentulous patients. Materials and methods: Edentulous patients attending a university hospital were examined for the presence of OMCs, and demographic data were recorded. Statistical analysis was carried out on SPSS software; the following statistical tests were utilized: descriptive statistics, The Mann Whitney U test, Spearman’s Rho rank correlations, and The hierarchical logistic regression analysis. Results: A total of one hundred and sixty-one participants were examined (34 females and 127 males with a mean age of 59.08 years). More than half of the participants (59.6 %) were non-denture wearers and (40.6%) were denture wearers. Longer edentulism, using dentures for longer duration, and the use of more previous dentures were associated with higher Atwood’s ridge classification. Smoking was associated with higher prevalence of OMCs, particularly hairy tongue, frictional keratosis, smokers’ palate, and leukoedema. Denture wearers had more denture stomatitis and denture induced hyperplasia, and less frictional keratosis than non-denture wearers. Participants with cardiac disease had more incidences of geographic tongue and tie tongue. Conclusion: Mucosal changes with increased age, smoking, medical conditions, and medications may be superimposed by wearing complete dentures.

Importance of Osseoperception and Tactile Sensibility during Masticatory Function in Different Prosthetic Rehabilitations: A Review

Background and Objectives: Tactile sensibility is an important characteristic for evaluating the masticatory efficiency in different occlusal situations. When a tooth is extracted, relevant proprioceptors from the periodontal ligament get lost; and after the rehabilitation of this abscess by means of oral prosthesis, this sensibility decreases influencing masticatory function. Osseoperception is a sensitive phenomenon associated with dental implants that allows an increased tactile sensibility to those wearing implant prostheses. The purpose of this study was to determine the difference in tactile sensibility values between implant prosthesis, complete dentures, and natural teeth through a review of the available literature. Materials and Methods. In order to dissect the information, 24 articles from 2004 to 2021 were analyzed from MEDLINE, PubMed Central, and Web of Science databases. These articles were directly related to measuring tactile sensibility in different situations and demonstrating the influence of osseoperception in an improved masticatory function. Results: Tactile sensibility in implant prosthesis is slightly reduced compared with natural dentition but presents improved values with regard to complete dentures. Conclusions: Implant prosthesis are more effective during masticatory function than complete dentures, as they present an increased tactile sensibility, very similar to that present in natural dentition. This enhanced sensibility in implants is due to the osseoperception phenomenon.

Patients’ Satisfaction and Oral Health-Related Quality of Life of Edentulous Patients Using Conventional Complete Dentures and Implant-Retained Overdentures in Saudi Arabia

The aim of this study was to compare patients’ satisfaction and quality of life (QoL) when using implant overdentures vs. conventional dentures. The QoL of Saudi patients who were provided mandibular implant-supported overdentures was assessed using a structured questionnaire. Overall satisfaction; ability to speak, eat, and chew food; comfort; esthetics; stability; and satisfaction of general oral health were measured. A total of 48.3% vs. 6.9% were, overall, very satisfied with their implant overdentures and conventional dentures, respectively. A total of 37.9% of the patients were very satisfied regarding speaking with their implant overdentures vs. 17.2% with conventional dentures. Furthermore, 41.4% were very comfortable with their implant overdentures vs. 5.2% were very comfortable using conventional dentures. However, only 15.5% were very satisfied with the esthetics of the conventional dentures compared to 43.1% being satisfied with implant overdentures. Only 1.7% were very satisfied with the stability of conventional dentures vs. 44.8% being satisfied using implant overdentures. About 8.6% of the candidates were very satisfied regarding chewing food with conventional dentures vs. 36.2% being very satisfied using implant overdentures. Approximately 10.3% were very satisfied with their general oral health using conventional dentures compared to 29.3% being very satisfied using implant overdentures. Mandibular implant overdentures had a strong impact on patients’ quality of life over conventional complete dentures and should be considered the minimum standard of care provided to completely edentulous patients.

DIGITAL OCCLUSAL ANALYSIS AND ORAL HEALTH-RELATED QUALITY OF LIFE OF PATIENTS WITH 3D PRINTED COMPLETE DENTURES VERSUS CONVENTIONAL DENTURES

Background: 3D printed complete dentures fabrication with computer-aided designing and computer-aided manufacturing (CAD/CAM) techniques is becoming popular nowadays. However, studies that analyzed the occlusal forces distribution using recent digital methods as T-scan III and further evaluated the dentures effect on patient`s life quality were lacking. Objectives: Evaluation of the occlusal forces distribution using T-scan III, and evaluation of the oral health-related quality of life (OHRQoL) using Oral Health Impact Profile for Edentulous Patients (OHIP-EDEN) questionnaire for 3D printed complete dentures and comparing it with conventional denture fabrication techniques. Methods: Twenty completely edentulous patients were selected and divided randomly into two equal groups according to manufacturing technique group I (patients who received conventional complete dentures), and group II (patients who received 3D printed complete dentures). For all patients, occlusal force analysis (percentage of applied occlusal force on both sides) was performed using the T-Scan III (digital occlusal analysis system). Also, OHRQoL was assessed using (OHIP-EDENT) questionnaire. Results: In the digital occlusal analysis, comparison between right and left sides regarding occlusal forces distribution revealed a significant difference in group I (conventional denture), while in group II (3D printed denture), it revealed an insignificant difference. Regarding, OHIP-EDENT patients in group I (conventional denture) revealed higher scores than group II (3D printed dentures). Also, the correlation between occlusal forces & (OHIP-EDENT) scores revealed a strong negative significant correlation. Conclusions: The 3D printed complete dentures fabricated using CAD/CAM technology proved to be more superior over conventional methods in terms of digital occlusal force analysis and Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT). However, further studies are required on more patients to decide the exact superiority of one technique over the other after long-term follow-up periods.

Association Between Depression and Dissatisfaction with Complete Dentures

Objective: The aim of this study was to find out the role of depression in complete denture dissatisfaction and to determine frequencies of depression among the satisfied and dissatisfied patients. Study design: A cross sectional survey was carried out at Department of Prosthodontics, De’Montmorency College of Dentistry. Punjab Dental Hospital. The sample size was 80 edentulous patients having adequate maxillary and mandibular ridges. Methodology: The patients selected would be wearing complete dentures for the first time. All dentures were carefully designed. A socio-demographic form and depression rating questionnaire was filled by every participant involved in the study. After six months, satisfaction or dissatisfaction with the provided complete denture set was assessed through a separate questionnaire. The patients’ opinion concerning satisfaction with their dentures and depression was recorded and statistical analysis done. The results showed that 36.25% depressed versus 63.75% non-depressed. 28.75% were dissatisfied versus 71.25% satisfied. Conclusion: It was concluded that depression played a significant role in decreasing the satisfaction rating in first time denture wearers. Keywords: Depression, dissatisfaction, complete dentures,

Evolution of Chewing Force in Geriatric Edentulous Patients

Objective The aim of this study was to assess the evolution of chewing force in edentulous geriatric patients rehabilitated with complete dentures. Chewing function is compromised in individuals who lose all their teeth, as well as in those with complete dentures. The maintenance and recovery of the chewing function in these patients require replacement of the lost natural teeth. Materials and Methods In this study, the chewing force was evaluated by electromyographic analysis of the temporalis and masseter muscle endings in 120 patients with old and new bimaxillary complete dentures. Results Replacement of complete dentures was shown to improve stability, retention, occlusion, and support of the prosthesis. All jaw movements were evaluated using electromyography to assess the evolution of chewing force with and without occlusal adjustment, identify premature contact points, identify occlusal interference, respect the balanced occlusal scheme, and assess the increase in muscle strength. This study found that muscle strength in patients with prosthesis without occlusal adjustment was 527.1 N but was higher for prostheses with occlusal adjustment at 614.7 N, and this strength of 614.7 N was maintained after 1 month of control. Conclusion The chewing force evolved in patients with complete dentures, and an increase was observed when occlusal adjustment was performed.

Management of Buccal Screw Access Hole Positioning for Implant Fixed Complete Dentures: A Report of Two Patients and a Proposed Decision Tree

The present report demonstrated the use of two methods to correct the positioning of buccal screw access holes in both implant- and abutment-level implant-supported fixed complete dentures in two patients. The report suggests that nonaxially tightened abutments (in this report, dynamic abutments), angled multi-unit abutments, and the use of a milled framework with individual crowns aid in masking buccal screw access holes while maintaining the benefits of a screw-retained design. A decision tree is also proposed to facilitate the workflow when faced with such clinical scenarios.

Clinical guide to border moulding and secondary impression in complete dentures

One of the major reason for a successful denture treatment is a good impression and the cast made out of it. It’s a well known fact, that the denture can only be as good as the impressions made. Therefore, attention to every detail and depth of the impressions plays a pivotal role for a successful clinical result, for which border moulding is an essential procedure for the same. Impressions convey operator’s extent of knowledge, understanding and the clinical results that can follow. A combination of a sound knowledge, along with acquired skill, experience, and patience can result in a successful and aesthetic prosthesis with adequate retention, stability and support with minimal post placement corrections. This article gives an insight into the necessary requisites to be followed during border moulding and secondary impression in making of a successful complete dentures.
