상호 호환성 있는 임프란트 지대주와 고정체간의 적합도에 관한 연구

Dental implantology has been one of the most rapidly widespreading and developing fields of dental practice. Recently, various implant systems were supplied, especially interchangeable implant abutments and fixtures were supplied. The purpose of this study was to examine the fit of various implant interchangeable abutments - Steri - Oss fixture interface. The maginal fit was measured by means of a scanning electron micro scope(SEM). The following results were obtained: 1. The largest gap was shown when Estheticone abutment of Branemark system was connected with Steri - Oss fixture (28.10 ± 6.69/mi) 2. In case of UCLA type abutments were connected with Steri-Oss fixture, the size of gap was shown in the order of the case of Branemark UCLA abutment (5.67 土 3.43/mi)，the case of Steri-Oss HL Hexed abutment (3.96±1.15；«m)，the case of 3i Gold UCLA abutment (3.01±1.35//m). 3. It seems that the interchangeable abutments, except the case of Estheticone abutment of Branemark system, can be used because most of intechangeable abutments don t have large difference in gap.
