Masticatory Efficiency

INTRODUCTION: Study aimed to investigate the influence of mandibular residual ridge shape on masticatory efficiency in complete denture wearer. MATERIAL & METHODS: Twenty-eight complete denture wearers of age group 45-65 who received their complete dentures and who had no complaints in daily use of them were selected for the study. The mandibular residual ridge was evaluated by using a replica of the ridge obtained using silicone impression material The basal area of the replica was measured by a Cercon eye scanner. The volume and the height of the replica were then mathematically calculated. Masticatory efficiency in each subject was measured by the sieving method. The data obtained were analysed through Karl Pearson’s coefficient of correlation. RESULTS: The results of this study showed significant correlation of the masticatory efficiency to the basal seat area, volume as well as to the height of the mandibular residual ridges. Among the three parameters, the basal area showed the strongest correlation. CONCLUSION: From this study, it was concluded that the basal area of the denture foundation greatly influenced the masticatory efficiency when compared to the volume and height of the mandibular residual ridge.

ABSTRACT Objective To determine the denture hygiene habits in complete denture patients according to their age and time of dentures. Methods In this study a self administered structured was developed to know the attitude of the patients regarding denture hygiene in the department of Prosthodontics. The total study sample consisted of 230 subjects including 124 (53.9%) males and 106 (46.1%) females. Data was analyzed using SPSS version 15.0 with chi-square test at p-value <0.05. Results Nearly half of the subjects clean their dentures daily once. Participants from the younger age group and who had been wearing dentures since 2 years maintain better frequency of cleaning. The majority of these subjects used water and brush for denture cleansing. After seeing the condition, half of the dentures were rated as good 50.3%, followed by fair and poor as 29.5 and 20.2% respectively. Clinical significance Poor condition of complete dentures seen in the population is mainly due to irregularly cleansing habits and also less usage of cleansing solutions. Dentists should give proper instructions regarding maintenance of denture hygiene. How to cite this article Apratim A, Shah SS, Sinha M, Agrawal M, Chhaparia N, Abubakkar A.

ABSTRACT Objectives A combination of the neutral zone and the polished surface impression techniques is a useful method to reserve the functional and physiological forms of the underlying mandibular residual ridge by enhancing both retention and stability in Malaysian geriatric patients (2-year clinical study). Materials and methods A total of 25 Malaysian geriatric patients have participated in the current study. Two sets of dentures were served to the patients. The first set was constructed according the conventional method of complete denture construction whereas the second set was constructed by using neutral zone and polished surface impression techniques. Results The patients were followed up for 2 years and the obtained results showed that all patients have stopped using the conventional dentures and continued with the test dentures. The comparative analysis exhibited significant difference (p < 0.05) in favor of test dentures. Conclusion Combination of the neutral zone and the polished surface techniques can impart a physiological reservation to the underlying residual ridge without changes. Statement of problem It is common for completely edentulous geriatric patients to have resorbed mandibular residual ridge because of the process of aging. Some surgical interactions are contraindicated for this age group of patients, so, neutral zone technique and/or polished surface impression verified effective in improving stability for lower complete dentures. In spite of the fact that the above mentioned methods often used to enhance stability of complete denture, most of the studies were relying on only one of those methods to improve stability rather than retention. Researcher hypothesis stated that a combination of the neutral zone and the polished surface impression techniques should be performed together to enhance both stability and retention and henceforth reservation of the residual ridge under mandibular complete dentures issued to the patients with a constant follow-up for two consecutive years.

Background: Ridge morphology is one of the important recognized factors affecting denture retention, stability, support and masticatory function in edentulous patients. The form of ridge affects the planning as well as determines the prognosis of treatment. The objective of this study was to assess maxillary residual ridge morphology according to American College of Prosthodontists (ACP) classification system and to find association between type of ridge morphology of maxillary arch with age and duration of edentulism.     Methods: The study was conducted among 87 completely edentulous patients above 40 years of age visiting department of prosthodontics Nepal Medical College. The morphology of maxillary residual ridges were clinically evaluated and classified according to criteria given by American College of Prosthodontists (ACP) classification system. The findings were associated with age, sex, duration of edentulism and complete       denture wear. Results: In this study, more than two thirds of the patients belonged to the age group of 60 – 80 years and their mean duration of edentulousness was seen to be 5.7 years. One fifth of the patients were using previous complete dentures. Type A maxillary ridge morphology was found to be the most prevalent. The type of maxillary ridge morphology was not found to be associated with either age or gender of an  individual however it varied significantly with length of edentulism and duration of complete denture wears.              Conclusions: Within limitations, it can be concluded that maxillary ridge morphology was not associated with age of an individual however the longer duration of edentulism or complete denture use would make the type of ridge morphology more unfavorable. Keywords: maxillary ridge; length of edentulism; residual ridge resorption; ridge morphology.

This present study describes an impression technique to rehabilitate patients with flabby ridge in pre-maxilla through complete dentures. The proposed technique consists on the association of nondisplacive impression of the flabby area in the primary and functional impression. Therefore, a primary impression was performed with irreversible hydrocolloid with a dual impression. The impression material was removed at the region corresponding to the flabby area, characterizing a window, where a re-impression was conducted with the same material in a more fluid consistency. The functional impression was executed with a custom tray with perforations at the flabby area fabricated over a primary anatomic cast previously relieved. As a result, an anatomic impression with reduced compression over the flabby ridge was obtained. Moreover, an accentuated decrease of the mucosa compression was obtained through the material overflow from the custom tray perforations at the functional impression. After the acrylization of the prosthetic piece, a delimited box corresponding to the flabby mucosa in the prosthesis base was verified. Thus, it is concluded that the association of techniques proposed in this study reduced the compression over the flabby ridge area resulting in a complete denture copying anatomically the flabby area at rest. Thereby, in this case through a precise negative reproduction, a more favorable retention of the maxillary complete denture was obtained in patients with flabby ridge at the pre-maxillary area.

ABSTRACT Aim Oral mucosal lesions are frequently observed in institutionalized elderly patients more than other age groups. The aim of this study was to determine the prevalence of epulis fissuratum and denture stomatitis and their associated causes in dependent elderly complete denture wearers. Materials and methods This study was conducted in dependent elderly complete denture's wearers living in four randomly selected nursing homes located in Tehran. Associated factors such as gender, age, use of medication, site of nursing home, denture quality and denture-wearing habit were studied. Results Overall, 674 patients were examined; 201 had complete denture. The prevalence of denture stomatitis was 36%. There was significant relationship among the prevalence of denture stomatitis with gender and denture wearing period (p < 0.05). The prevalence of epulis fissuratum was 16.4%. There was significant relationship among the prevalence of epulis fissuratum with gender, denture quality and denture wearing habit (p < 0.05). Conclusion In this particular dependent age group, the prevalence of oral mucosal lesions is high and the mentioned associated factors should be noticed. Clinical significance Dependent elderly complete denture wearers need more support and motivation for reducing the prevalence of these particular denture-associated oral mucosal lesions.

Objectives: University-led dental clinics are rarely seen as core to the national healthcare system. Thus, when publicly funded universities experience a decline in government support, dental clinic services operated by students are confronted by a potentially inadequate operating budget. Prompted by the need for strategic resource allocation, this study seeks to quantify the resources consumed in the construction of complete dentures by undergraduate students in an effort to identify opportunities for cost-cutting measures. Methods: Clinical cases were retrieved from the logbooks of graduating students of Class 2015, and patient records were reviewed to identify and quantify all clinical and laboratory procedures involved in constructing a set of complete dentures. Cost estimation was carried out using the activity-based method on the basis of direct medical costs. Results: A total of 83 patient records were reviewed. The average number of visits required to fabricate a set of complete dentures was 10 (range, 6–20 visits) with an average total cost of MYR2131±538 (€450±114). The number of visits contributed substantially to the total cost, and procedures requiring multiple visits included secondary impression and jaw relation recording. The major cost components were dental equipment (44%), laboratory costs (28%), dental consumables (17%), salaries (7%), and dental instruments (3%). Conclusion: The operating cost for training students in denture fabrication is substantial. Schools should formulate strategies to reduce the number of patient visits by ensuring that students optimize the time spent per visit. A financially sustainable model to fund dental training is necessary to ensure that quality of care is not compromised in university-led clinics.

OBJECTIVE: This study aimed to evaluate maximum bite forces (mBF) in dominant (DS) and non-dominant sides (NDS) at certain time periods after the insertion of new complete dentures based on prior experience and gender.MATERIALS AND METHODS: A total of 88 patients, complete denture wearers (CDWs), were examined. The maximum bite force at the intercuspal position between the first molars in 3 seconds was registered and recorded with piezoelectric gnathodynamometer. The procedure was repeated 3 times in identical conditions, with relaxation intervals of 1 minute between repeats and the limiting factor was the subjective feeling of pain. Testing of parametric data was performed with One Way Repeated Measurement of ANOVA test.RESULTS: The average mBF values increased during the observational period, both on the DS and NDS, with significant difference in DS, which was greater. The analysis of one-factor variance showed that there were differences of average mBF values in DS and NDS during six consecutive measurements (mBF–DS = 11.3, p = 0.0001, and mBF-NDS = 2.26, p = 0.047). Significant changes in the masticatory force (mBF) on the DS and NDS is explained by different measurement times and with the prior experience with complete dentures, BF–DS = 11.76, p = 0.0000; mBF–NDS = 2.42, p = 0.0351; mBFe–DS = 40.48; P = 0.0000 mBFe–NDS = 39.93, p = 0.0000.CONCLUSION: mBF represents a significant discriminating variable of the level of functional adaptation of new complete denture wearers (nCDWs) about the initial measurements.
