Abstract
Criteria for selection of removable partial denture abutment teeth is broad, depends upon many factors, and its estimation of prognosis there by is difficult. In order to establish diagnostic parameters, the degree of tooth quality must be determined.
The aim of this study was to test via statistical analysis those factors which can affect tooth quality, and provide risk factors influencing removable partial denture abutments.
Subjects including patients requiring extractions of abutment teeth were divided into two groups of vital and nonvital teeth. Data was collected based on clinical examinations, and assigned to various categories of factors.
In the vital group, factor contribution to poor prognosis included periodontal condition, bone resolution, pocket depth and CPITN, which proved to be significant risk factors. In the nonvital group, biomechanical factors, such as occlusal and prosthesis factors, were shown to be significant risk factors.
