PREVALENCE OF ALVEOLAR RIDGE DEFECT ACCORDING TO SEIBERT’S CLASSIFICATION IN PATIENT WITH FIXED PARTIAL DENTURES - A RETROSPECTIVE STUDY

Abstract

Alveolar ridge defect occurs due to complex extraction of tooth which leads to a certain amount of bone loss and it occurs due to injury, congenital defects, Denture wear, periodontitis and truama. Alveolar ridge defects were classified by Seibert's Classification which identified the ridge defect. Alveolar ridge defects can be classified as a loss of labial cortical or medullary bone or sometimes both. Thereby replacing the missing tooth and to restore good esthetics, phonetic, and mastication. To provide a proper treatment plan and treatment options can be assessed for successful outcomes. Hence, the purpose of this study was to assess the prevalence of alveolar ridge defect using the Seibert's classification in patients with fixed partial dentures. The retrospective study was conducted among patients with Fixed partial dentures. The data were reviewed of 86,000 patient records between 1st June 2019 and March 30st 2020 from which 407 subjects of fixed partial dentures were assessed for alveolar ridge defects using the seibert's classification. The Collected data was tabulated in the excel sheet which was imported to SPSS software Version 20 for statistical analysis. Out of 407 patients 226 (55.53 %) were more prevalent than females 186 (44.47%). Most commonly involved age group among 31-40 years (29.24%). Class III was the most commonly observed type of defect 49.14%, followed by class I 44.96% and Class II 5.90%. Sextant II (36.36%) was most commonly affected followed by Sextant VI (22.11%). Male patients were more commonly affected than the female patients, the most common age group was 31-40 years of age.
