임프란트 환자의 유형 및 분포에 대한 연구

Abstract

Nowdays, the implant treatment has become a widely accepted treatment for the patients and even for the general dentists. Unlike the other treatment like bridges or dentures, this can preserve the adjacent teeth without any modification and the existing bone. The following results on patient type and implant distribution were compiled from 7654 implant cases of 2763 patients treated at the periodontal dept. of Yonsei University Hospital during 1992 to 2006. 1. There are no dissimilarities between men and women, with patients in their 40, 50s accounting for 52.7% of patients and 53.8% of implant the largest share of patients and implant treatments. 2. Mn. posterior area accounted for 52.4% of implant treatments followed by Mx. posterior area(31.4%), Mx. anterior area(11.0%) and Mn. anterior area(5.0%). 3. The major cause of tooth loss is periodontal disease, followed by dental trauma and congenital missing. 4. In the distribution of bone quality for mandible, type II was most, followed bytype III, type IV and type I.As the maxilla, type III most followed by type II, type IV, and type I. 5. In the distribution of bone quantity for maxillae, type B was most(49.9%), followed by type C, type D, type A, and for type E. 6. The majority of implants were those of 10-15mm in length (89.0%) and wide diameter in width (52.6%). The results provided us with basic data on patient type, implant distribution, bone condition, etc. We wish that our results coupled with other research data helps assist in the further study for better implant success/survival rates, etc.
