Rehabilitation strategies for partially edentulous-prosthodontic principles and current trends

Abstract

DISCUSSION Prosthodontic 'Decision Making'The prosthodontist is daily confronted with making decisions to replace missing teeth or defective restorations, to retain or extract periodontally compromised potential abutment teeth, or to prescribe a specific occlusal scheme for a restored dentition. This process is an extension of the clinician's opinion based on his knowledge and clinical experience and strongly influences the treatment modality chosen for a particular patient. Tooth Loss-'Functional Loss'A healthy occlusion is characterized by absence of pathology, satisfactory function and adaptive capacity. Loss of one or more teeth disturbs the functional balance of the remaining teeth and may result in migration, widening of proximal contacts and food impaction, bone resorption, occlusal interferences, loss of vertical dimension, altered mastication, anterior overloading, temporomandibular dysfunction with para-functional activities, altered phonetics, and aesthetics and psychological problems such as affected self-esteem and confidence. 1 A partially edentulous dentition can be practically classified into two groups: 1. Uncomplicated impaired dentition where tooth loss is the only anomaly. 2. Complicated impaired dentition, which is characterized by presence of complicating factors such as poor oral hygiene, caries, periodontal disease, and migration due to tooth loss. Clinically, the uncomplicated impaired dentition can be treated immediately. However, in complicated cases, the causative factors should be identified and treated first and only then should the prosthetic rehabilitation be started. Current Treatment Options for Patients with Missing Single or Multiple TeethIn cases of a missing single tooth the options are interim removable partial denture, cast partial denture, resin bonded prosthesis, fixed partial denture, and implant retained prosthesis.In cases of missing multiple teeth the options are interim removable partial denture, cast partial dentures, resin bonded prosthesis (restricted by length of edentulous span and residual ridge morphology), fixed partial denture (FPD), cast partial/ FPD combinations or implant supported prosthesis.

A Viable Rehabilitation Approach with Maxillary Cast Partial Denture and Mandibular Over Denture - A Case Report

“…The choice of treatment is also critically dependent on the status of the abutment teeth, which are often periodontally involved. 5 The stress on the abutment due to the diff erence in nature and behavior of the tissues supporting RPD is critical for long term success of prosthesis. In this case, the stress control on abutment is achieved through dual impression technique, broad coverage and stable denture base, rigid design, and clasp design.…”

“…In a partially edentulous patient, the loss and continuing degradation of the alveolar bone, adjacent teeth, and supporting structures infl uence the level of diffi culty in achieving adequate prosthetic restoration. [3][4][5] Treatment options for partially edentulous patients with missing single or multiple teeth range from a provisional removable partial denture, a defi nitive cast partial denture, fi xed partial denture and Implant supported prosthesis.…”

Knowledge and Awareness of Precision Attachments among Dental Students

“…The design of precision dentures may not involve an exceptional degree of expertise and is within the domain of the specialist who will prepare teeth to obtain full crowns and install ixed bridges. (Souza et al, 2011;Tylman and Malone, 1978). Precision attachment typically consists of a strong metal receptacle (a matrix) and a closely aligned component (patrix) (Souza et al, 2011).…”

“…(Souza et al, 2011;Tylman and Malone, 1978). Precision attachment typically consists of a strong metal receptacle (a matrix) and a closely aligned component (patrix) (Souza et al, 2011). The patrix is normally the male part, and the matrix slot is the female part.…”

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

“…The problems of these cases have been solved by various concepts beginning from using the conventional RPD until introducing implants as a solution in many treatment options. Despite the problems associated with the use of the conventional partial denture; it remains the commonly used restoration [3], [4], [5].…”
