Impact of Removable Partial Denture Type on Patient Satisfaction and Abutment Survival Rate-RCT

Abstract

BACKGROUND:Patient’s satisfaction and the preservation of abutments is the most important outcomes that the clinician seeks during fabrication of any dental treatment, especially when it is concerned with removable prosthodontic rehabilitation.AIM:The present study evaluates three different Removable Partial Denture (RPD) types restoring mandibular class II modification I edentulous cases with regards to patient’s satisfaction and abutments survival.METHODS:Forty-two partially edentulous patients were divided into three groups (Group I rehabilitated with Vitallium RPD, Group II rehabilitated with Vitallium RPD where the modification area restored with the surveyed bridge, Group III rehabilitated with Thermopress RPD). The patients were followed up for twenty-four months. Using a questionnaire, prosthodontic maintenance required was documented at the delivery and after 3 months.RESULTS:There was a significant difference regarding patient satisfaction for group III (P-value <0.05) while for groups I and II there was a non-significant difference (P-value >0.05). Regarding the survival rate, there was a non-significant difference between the three groups (P-value >0.05) at the end of twenty-four months of follow up.CONCLUSION:Patient satisfaction and abutment survival were better with Thermopress RPD than conventional Vitallium RPD or Vitallium RPD with a surveyed bridge restoring the modification area. Although a non-statistically significant difference was found in the survival rate of abutments between groups, a clinically important result was revealed as no abutments failures were reported in the Thermopress group.

Factors affecting patient satisfaction among patients undergone removable prosthodontic rehabilitation

“…Material used in removable prosthesis fabrication also have an impact on the patient sastisfaction which was reported in a study done by Sherif A. Sadek and Dina Elawady[ 16 ] in which they concluded that patient satisfaction was improved with thermopress removable prosthesis as compared with vitallium removable prosthesis. In one of the clinical trials done by Fueki K[ 17 ] et al reported that patient satisfaction was higher when the removable prosthesis was fabricated with thermoplastic resin as compared with metal clasp retained removable prosthesis.…”

Radiographic Evaluation of Telescopic Pier Abutments in Mandibular Distal Extension Cases

“…Abutment teeth were peri-apically radiographed to notice any carious lesions, assess pulp size, inspect length, size, shape, number and inclination of roots. Moreover, this played role in assessing abutment's supporting structure, investigating lamina dura's continuity, periodontal space's width, crown/root ratio and detecting of any periapical or periodontal lesions (5).…”

Evaluation of the Empower model of care for partial denture clients in a public oral health care setting

“…Considerable variations exist in removable partial denture design, materials (acrylic vs. cobalt‐chrome), span and indication. Data from the literature would indicate that the survival rate of abutment teeth supporting the denture has been reported in the literature to be from 7.5% to 15% per year 22–24 . Estimates of the necessary sample size were based on Hsieh and collaborators 25 and Bujang and collaborators 26 recommendations for minimum sample size to conduct a multiple logistic regression analysis.…”

Using a survival rate of 15%, as a proxy to the need to include additional teeth in removable partial dentures, [22][23][24] some 534 are required to perform a multiple logistic regression analysis yielding a power of 0.80, at a two-sided significance level of 0.05, using up to 8 independent variables.…”
