Current Trends In Complete Denture Education In Undergraduate Dental Colleges Of Pakistan.

To determine the current trends in complete denture education in undergraduate dental colleges. The survey-based study was conducted in April and May 2020 at undergraduate dental colleges of Pakistan, and comprised heads of the Prosthodontics Department at all dental colleges across Pakistan having at least one batch of final year dental students. Data was collected using an online predesigned questionnaire that explored theoretical and practical teaching patterns of complete denture prosthodontics in the undergraduate years, and the materials and practices of students when constructing complete dentures in the clinics. The participants were given the option of choosing more than one option where needed. Data was analysed using SPSS 23. Of the 49 subjects approached, 40(81.6%) returned the forms duly filled; 11(27.5%) from public-sector institutions and 29(72.5%) from the private sector. There were 26(65%) institutions which required that their undergraduate students fabricate 2-4 conventional complete dentures. In all 40(100%) colleges, faculty gave live clinical demonstrations before students fabricated conventional complete dentures in the outpatient departments. Teaching strategy included small group discussions in 25(62.5%) institutions. Green stick 40(100%), zinc oxide eugenol 40(100%) and impression compound 39(97.2%) were the materials of choice for various steps of impression making. In all the 40(100%) institutions, students fabricated conventional complete dentures during their prosthodontics rotation. Immediate, copy and overdentures were constructed by students in 8(20%), 3(7.5%) and 8(20%) institutions, respectively. Majority of the dental schools used similar impression materials and techniques for fabricating conventional complete dentures. Didactic teaching of conventional and unconventional complete dentures was being carried out at a huge majority of the dental institutions studied.

Preprinted anterior tooth guides used to assist complete denture tooth arrangement

Although many advancements have been made in preventive and reconstructive dentistry, treating edentulism still remains a challenge.1 One of the challenges in complete denture prosthodontics is communicating information regarding the optimal shape and position of the maxillary anterior teeth to the dental laboratory technician.

Base Metal Denture Bases - Clinical indications

It has been more than eight decades since the introduction of polymethylmethacrylate (PMMA) in prosthetic dentistry. Despite so many advances in material science, the use of PMMA is unabated. Its ability to be molded into desired shape and biocompatibility, are significant for its success. Certain clinical conditions do however contraindicate its uses in prosthesis, and pave way for base metal alloy denture bases. These conditions are so common, yet they are missed clinically by even most astute clinicians. This case series in the form of multiple case reports provides the reader a glance into the clinical indications for metal denture bases in complete denture prosthodontics. Each case has been explained on the basis of its particular indication. The advantages and disadvantages of metal denture bases in such situations has been discussed. A case of menopause, sorption related denture changes, need for improving oral stereognostic ability and cases where poor adaptation of denture base acrylic is inevitable are key description of this article.

ATTITUDE OF CLINICIANS TOWARDS CLINICAL DECISION-MAKING IN PROSTHODONTICS

Objective: To assess the attitude of resident and consultant Prosthodontists towards clinical decision-making in complete denture prosthodontics
 Study Design: A cross-sectional study.
 Place and Duration of Study: Armed Forces Institute of Dentistry, Rawalpindi, from Nov 2019 to Jan 2020.
 Methodology: Fifty trainee and consultant prosthodontists from all over the country were included in the study. A questionnaire consisting of 10 questions aimed at assessing the approach towards clinical decision-making in complete denture prosthodontics was circulated among the study subjects using Google Forms. Data was analyzed using SPSS version 24.
 Results: Around 20 (40%) prosthodontists regarded patient’s personal values and preferences to be “very important” in clinical decision-making in contrast to their own values. Most of the clinicians 47 (94%) believed their patients were quite satisfied with them and around 31 (62%) prosthodontists believed that “choice of the best treatment results from negotiation between patients and clinicians after they have shared technical information as well as their values and preferences about the options”. No significant difference was observed in choice of response between males and females or between prosthodontists with varying clinical experience for any of the questions asked (p>0.05).
 Conclusion: Prosthodontists participating in the present study demonstrated a positive attitude towards shared decisionmaking in complete denture prosthodontics. No differences were observed between males and females in terms of attitude towards shared decision-making practices.

Problems faced with complete dentures by elderly people attending clinics in dental hospital, Peradeniya

Purpose: This study aimed at assessing physical, social and psychological problems faced by complete denture wearers and to identify the association of socioeconomic factors of the individual with the problems related to complete denture-wearing for early identification and treatment planning to improve their oral health and wellbeing. Materials and Methods: This was a descriptive cross-sectional study conducted at the Dental Hospital, among 96 complete denture wearers, who were 60 years and above. A pre-tested and structured interviewer-administered questionnaire was used to collect data through telephone interviews. Descriptive statistics were obtained as frequencies and percentages. Chi-Square test was used to assess the association between selected demographic variables and denture information. Results: Most of the participants (71.9%) used their present dentures for 0-5 years. Gender and occupation significantly influenced the frequency of cleaning the mouth. The most common problems were loose dentures, longer time is taken to complete meals, consciousness while eating, difficulty in chewing and food accumulation beneath dentures. Occupation, family support and family income had significant associations with some problems related to complete dentures. Family support was the major factor that had significant association with social interactions such as difficulty in speaking, limitation in facial expression, avoiding going to parties and avoiding leaving home/resident environment. Most of the socioeconomic factors had a strong influence on participants' self-confidence. Conclusion: Complete denture prosthodontics should focus on patients' physical and psychosocial problems with their socioeconomic background to identify problems, to restore their confidence level and improve quality of life.

A Review on Occlusal Plane Analysis in Edentulous Patients

Aim: The Purpose of the present review was to determine the occlusal plane in edentulous patients.Objective : Occlusal plane orientation is an important factor in the construction of a complete denture.Occlusal plane could be oriented using landmarks in the maxillary arch as well as the mandibular arch .Many methods have been used to establish the occlusal plane in complete dentures , but no method seemsto be fully acceptable. So it is always challenging for the prosthodontist to restore the existing occlusalcondition with a suitable prosthesis.Materials and Methods : : An electronic search engine without time/ language restrictions was taken fromGoogle Scholar .Conclusion: This article reviews different techniques to determine and correct occlusal plane. HIP wasparallel to the occlusal plane , Ala-tragal line passing through lower part of the ala of the nose to inferiorposition of the tragus was relatively parallel to maxillary residual ridge. Therefore, this may be a viablereference in complete denture prosthodontics.

Evolution of the Temperament Theory and Mental Attitude in Complete Denture Prosthodontics: From Hippocrates to M.M. House

Some 2,500 years ago Hippocrates developed the "Temperament Theory" of the four humors (fluids) he identified as blood, phlegm, yellow bile, and black bile which then led to the ancient medical concept known as "humorism." In Greco-Roman medicine, these humors were believed to be the influencers of an individual's relative wellness or ill-health, served as a means to classify illnesses, and subsequently guided medical diagnosis and treatment. Centuries later modifications to Hippocrates' hypothesis were suggested for use in dentistry when selecting denture teeth and later as a means to classify the mental status and personality of complete denture patients. This paper examines the historic transition of the terminology, characteristics, and thinking behind the four humors with mention of key thinkers in this journey. Of particular note is the evolution in the application of this theory from its suggested use in medicine, proposed by Hippocrates, to the descriptions of mental attitudes and personalities of complete denture patients first described by Neil and subsequently popularized by M. M. House.

Assessment of Microbial Adherence on Conventional and CAD/CAM Complete Denture

Purpose: The aim of the study was to assess microbial adherence on maxillary complete denture carried by different fabrication techniques; the conventional and CAD/CAM ( computer-aided design and computer-aided manufacturing) techniques. Material and methods : Ten completely edentulous patients were selected and divided into randomly two equal groups: group I, patients received maxillary and mandibular complete dentures made of conventional heat-cured acrylic resin and group II, patients received maxillary CAD/CAM complete denture and mandibular conventional complete denture. Assessment of the microbial colonization of maxillary dentures for both groups was carried out after 3, 6 and 9 months after denture insertion. The tested microorganisms are Candida albicans (C. albicans), Staphylococcus aureus (S. aureus), Streptococcus mutans (S. mutans) and Escherichia coli (E. coli). Results: Comparison of microbial colonization count represented in colony forming unit per ml (CFU/ml). Change between group I and group II revealed that, group II has statistically significant lower CFU/ml than group I for all the tested microorganisms during the study period (P-value <0.05) except for E. coli after 3 months the difference between both groups was statistically non significant (p = 0.139). And there was a gradual increase in the microbial count during the time of using both types of dentures. Conclusion: CAD/CAM dentures showed less microbial colonization than conventional heat cure acrylic resin dentures. Further short-term and long-term clinical studies are needed to validate CAD/CAM technology in complete denture prosthodontics.

Preprosthetic surgery: An adjunct to complete denture therapy

Pre-prosthetic surgery is an integral part of Complete denture Prosthodontics. The ultimate goal of pre-prosthetic surgery is to prepare a mouth to receive a dental prosthesis by redesigning and smoothening bony edges which would otherwise cause hindrance in restoration of optimum health and function. This case report discusses how reduction of severe bony prominences and smoothening of irregular ridges resulted in achieving a better denture foundation which if left untreated otherwise would have resulted in sore spots and immense discomfort to the patient.

Resection of Large Ameloblastoma with Immediate Reconstruction: a Case Report

A 34-year-old woman attended the surgery service complaining of pain, dysphagia, dysphonia, and increased volume in the right hemiface since 10 years prior. Clinical examination showed a large bulge in the right mandibular region, with a firm consistency upon touching. Oral and lingual bulging caused protrusion of tongue. Dental dislocation and trauma to the lesion caused by the upper teeth were also observed. Imaging showed multilocular areas, bone expansion, and extension of the lesion to the contralateral molar region. Incisional biopsy was performed, and a diagnosis of multicystic ameloblastoma of plexiform pattern was made. The tumor was resected, and microscopic analysis confirmed the diagnosis. The patient underwent immediate reconstruction of the area using a customized acrylic resin prosthesis with a reconstruction plate of 2.4. Three months after surgery, the patient was free of painful symptomatology and was adequately rehabilitated with complete denture prosthodontics.

Survey of current materials and impression techniques for Complete Dentures among Nepalese Prosthodontists

ABSTRACTBackground: Impression making is one of the critical factors in determining success or failure of complete denture therapy. The precise reproduction of edentulous foundation is essential for retention, stability, and support of the removable prosthesis. Evidence suggests that there is variability in materials and techniques regarding impressions making for complete dentures. There is little published information on studies conducted among Nepalese Prosthodontists. The purpose of this study was to evaluate current materials andmethods for impressions for complete denture prosthodontics in Nepal. Materials &amp; Methods: A questionnaire based survey was conducted among Nepalese Prosthodontists. Ethical approval for the beginning of the study was obtained via Institutional Review Committee, Nepal Medical College. A self-administered anonymous questionnaire was distributed to the participants. Data were analyzed by using frequency distribution.Results: Majority of responses indicated use of irreversible hydrocolloid in stock metal tray for making the preliminary impression. The selective pressure was the predominantly used impression philosophy (78.3%). The most common material for the fabrication of custom trays was autopolymerizing acrylic resin (96.7%). All respondents border molded the custom tray prior to making the final impression. The final impression materials used were zinc oxide eugenol impression paste (73.3%), polyvinylsiloxane (11.7%), polyether (11.7%) and polysulphide (3.3%). Conclusion: Although there is variability in impression materials andtechniques used by Prosthodontists in Nepal for the fabrication of complete dentures, the results showed interesting trends. Most practitioners followed the traditional techniques of complete denture impression procedures.Keywords: complete denture; custom tray; edentulism; impression.

Effect of mucostatic and selective pressure impression techniques on residual ridge resorption in individuals with different bone mineral densities: A prospective clinical pilot study

Statement of problemAlthough different impression techniques have been advocated for complete denture prosthodontics, objective studies that predict their effect on alveolar bone resorption are lacking. PurposeThe purpose of this prospective clinical pilot study was to objectively evaluate the effect of complete dentures fabricated by different impression techniques on mandibular residual ridge resorption in individuals with different bone mineral density. Material and methodsNinety-six participants with edentulism, selected according to inclusion criteria, underwent bone mineral density assessment and were divided into normal, osteopenic, and osteoporotic groups. Half of the participants in each group were provided with dentures fabricated by selective pressure impression technique (subgroup SIT), and the other half were provided with dentures fabricated by mucostatic impression technique (subgroup MIT). Computed tomographic scans of the mandible were made at denture delivery and 1 year after prosthesis use to assess alveolar bone height and width difference at marked locations at and after denture delivery. The data obtained were analyzed with the Student t test (α=.05). ResultsSignificantly less reduction in mandibular ridge height and width was found in the MIT versus the SIT subgroups in both osteopenic and osteoporotic participants (P<.05). No significant subgroup difference was found for normal bone mineral density group, although resorption increased in height and width for the SIT subgroup. ConclusionsMandibular residual ridge resorption was reduced for dentures fabricated using the mucostatic impression technique compared with the selective pressure impression technique in individuals with diminished bone density.

DIGITAL TECHNOLOGY IN COMPLETE DENTURE PROSTHODONTICS: A REVIEW OF LITERATURE

Background: Computer-aided design and computer-aided manufacturing (CAD/CAM) technology has expanded to embrace implant, maxillofacial and removable prosthodontics including the fabrication of complete dentures. However, despite that the implementation of computer-aided technology with edentulous patients seemed to improve and simplify complete denture treatment as it significantly reduced the number of patient visits, yet still a limited number of reports described its use for complete denture fabricationObjective: This literature review will cast light on digital technology and its implementation in complete denture prosthodontics including its advantages, limitations, techniques and will present the articles that reported or investigated this topic and their outcomes including clinical or patient-based outcomesMaterials and methods: An independent electronic search of the English language literature was conducted by 2 investigators (authors), in bibliographic database MEDLINE, EMBASE, the Cochrane Library and Google up to March 2017 using certain key words. The electronic search was conducted in 3 stages in a systematic order. Stage 1, involved acquiring a record of titles from the electronic databases, which was then independently analysed by each investigator to extract relevant titles based on the predetermined inclusion criteria. The investigators independently applied the exclusion criteria, and any inconsistency was resolved by discussion. In uncertainty situations, the disputed article was included in the second (abstract) stage for contemplation. Stage 2 involved screening the abstracts of all selected titles by both investigators separately. Once more, any disagreement between the investigators was discussed, and, in uncertain situations, the abstract was included in the third and last stage of full-text analysis. At stage 3, all full text articles that were included were studied by the two investigators. This was followed by applying the final exclusion criteria and reviewing the final list of articles thoroughly and in depth to extract all relevant qualitative and quantitative data. Results: The review included a total of 20 articles. 2 studies described techniques for digital arrangement of denture teeth, 13 studies described techniques for digital fabrication of digital complete dentures either using rapid prototyping technology or computerized numerical control milling. The other 5 articles were clinical studies that assessed the clinical and patient-based outcomes of digitally-fabricated dentures.Conclusions: Digitally fabricated dentures can be an effective and time-efficient option for completely edentulous patients with favourable clinical and patient-centered outcomes. They are preferred by clinicians and patients as they significantly reduced clinical time and number of appointments, improved retention as well as digital archivability and hence reproducibility. However, dental literature lacks short-term and long term prospective clinical studies in this field to be able to reach definitive conclusions.

A comparative study to find out the relationship between the inner inter-canthal distance, interpupillary distance, inter-commissural width, inter-alar width, and the width of maxillary anterior teeth in Aryans and Mongoloids.

BackgroundOne of the most confusing and difficult aspects of complete denture prosthodontics is the selection of appropriately sized maxillary anterior denture teeth. Various guidelines have been suggested for determining the size of anterior teeth, but different opinions have been reported regarding their significance. In the study reported here, the relationships between facial measurements and the width of maxillary anterior teeth in two ethnic groups, namely Aryans and Mongoloids, were determined.ObjectiveThe aims of the study were to determine the inner inter-canthal distance (ICAD), inter-pupillary distance (IPD), inter-commissural width (ICOW), inter-alar width (IAW), and the combined width of maxillary anterior teeth (CW) in Aryans and Mongoloids and to determine the relationships between these measurements.Materials and methodsImpressions of the teeth of 170 dentulous subjects (85 males and 85 females) were made with alginate then Type IV gypsum product was poured in. Measurements of the cast maxillary anterior teeth at their widest dimension (contact areas) were made with the Boley gauge. ICAD, IPD, ICOW, and IAW distances were also measured with a Boley gauge.ResultsFor all 170 subjects, 85 Aryans and 85 Mongoloids, Pearson’s correlation coefficient (r) for IAW, IPD, ICOW, ICAD, and CW was calculated. In Aryans, highly significant (P<0.001) but weak correlations were found between CW and IAW, IPD, and ICOW. In Mongoloids, a highly significant (P<0.001) and weak correlation was found only between CW and IPD.ConclusionWithin the limitations of this study, the results suggest that the IAW, IPD, and ICOW for Aryans and IPD for Mongoloids can be used as a preliminary method for determining the width of the maxillary anterior teeth in edentulous patients.
