Prevalence of (alveolar ridge defect) using Seibert's classification in fixed partial denture patient.

Background: Alveolar ridge defect may occur due to injury, trauma, denture wears, and periodontitis. Based on Seibert's Classification, it can be classified into three classes: Class I (buccolingual loss of tissue), Class II (apicocoronal loss of tissue), and Class III (both loss of tissue). It is important to close the ridge defect by replacing the tooth loss and to achieve good esthetic, phonetic, and mastication. According to the classification, proper treatment plan and alternative can be determined for successful outcomes. Aim: The aim of this study is to assess the prevalence of alveolar ridge defect using Siebert's classification in fixed partial denture patient among Indian population. Materials and Method: This study was conducted in the Department of Prosthodontics, Saveetha Dental College. A total number of 55 of 60 patients with alveolar ridge defect are selected. Based on the Siebert's Classification (Class I, Class II, and Class III), the amount of destruction is analyzed to determine the alveolar ridge defect using this classification. Therefore, the statistical analysis is performed using Chi-squared test. Results: Based on the result, the prevalence of alveolar ridge defect due to trauma is 91.6% (55 of 60). According to Siebert's classification, the most common alveolar ridge destruction was Class III defect which is both buccolingual and apicocoronal loss of tissue of alveolar ridge, 24 (40.0%). This was followed by Class I defect which is buccolingual loss of tissue of alveolar ridge with 20 (33.3%) number of patients. Class II defect was the least with 11 (18.3%) which is apicocoronal loss of tissue of alveolar ridge. Conclusion: The prevalence of Siebert's classification helps in suggestion of various management techniques or treatment planning to the patient to ensure that the prognosis and treatment outcomes turn out to successful.
