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 8634 implant cases of 3303 patients treated at the periodontal dept. of Yonsei Dental College Hospital between 1992 and 2007 1. There are no dissimilarities between men and women, with patients in accounting for 49.8% and 50.2%. 2. Mn. posterior area accounted for 50.0% of implant treatments followed by Mx. posterior area(33.1%), Mx anterior area(11.4%) and Mn anterior area(5.4%). 3. The major cause of tooth loss is periodontal disease, followed by dental caries, trauma and congenital missing. 4. In the distribution of bone quality for maxillae, type III was most, followed by type II, type IV and type I. As for the mandible, type II was most followed by type III, type IV, and type I. 5. In the distribution of bone quantity, type B was most(46.8%), followed by type C, type D, type A, and for type E. 6. The majority of implants were those of 10-15mm in length (89.1%) and standard diameter in width (53.0%). 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.
