초록
The purpose of this study is to assess the mechanical properties of the ceramic abutment with washer. In this study, ceramic abutment were used, tested with 30 ° compression load, shear fatigue, adaptation accuracy test(rotation angle, contact interval), removal torque force test, torsional breaking force test. The 30° compression load was 729 N, the shear fatigue load was 275 N, adaptation accuracy test of rotation angle was within 3°, contact interval within 10 μm, and removal torque force test value is 18.88 N·㎝, torsional breaking force test value is 35.52 N·㎝. Ceramic abutment with a washer fitted have sufficient mechanical strength and may be substituted for titanium abutment.
