Prevalence of Ridge Defects According To Sieberts Classification in Patients Undergoing Fixed Partial Denture - A Retrospective Analysis

Abstract

In prosthetic dentistry, dentists may face challenges in treating patients with alveolar ridge defects in
edentulous areas. Alveolar ridge defect may occur due to injury, trauma, denture wear and periodontitis.
Based on Sieberts classification, it can be classified into three classes. class I- buccolingual loss of tissue ,
class II - apicoronal loss of tissue and class III - both loss of tissue. It is important to close the ridge defect
by replacing the tooth loss and achieve good esthetic, phonetic and mastication . According to classification,
a proper treatment plan and alternative can be determined for successful outcomes.The aim of this study is
to assess the association of sieberts classification for edentulous ridges in selecting the pontic design in FPD.
This study was conducted in saveetha dental college. A total number 778 patients with alveolar ridge defects
was selected. The data was collected using patient treatment details used in SIMATS and data was analysed
using SPSS software. Based on results, class I ridge defect was more common among all age groups and also
in all 6 sextrants . Class III ridge defect was more common in males compared to females. The p<0.005 which
is statistically significant . As age increases the ridge defects vary. It was concluded that the prevalence of
Sieberts classification helps in suggesting various management techniques or treatment planning to ensure
that the prognosis and treatment outcomes can be better and successful.
