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 intei face. 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 Bianemark system was
connected with Steri - Oss fixture (28.10± 6.69fnn)
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±3.43/AM), the
case of Steri-Oss HL Hexed abutment (396±l.15;um), the case of 3i Gold UCLA
abutment (3.01±1.3514n).
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.
