치과 임플랜트를 이용한 보철수복시 자연지대치와의 연결형태에 따른 응력의 광탄성학적 분석 = A study on the photoeastic analysis of stresses induced by the connection modalites between natural tooth abutment and dental implant

다국어 초록 (Multilingual Abstract)

The connection between natural tooth abutment and implant has been studied with various methods. This study compared the stress distribution during the function of four prosthesis with variant connection modalities design between natural tooth abutment and implant fixture. The four connection types are rigid, non-rigid, telescopic crown and free standing. Each specimen was examined and taken the photograph with 30Kg force.
the results were as follows.
1. Generally, the implant fixture has more stress concentration than the natural tooth abutment.
2. The specimens using the free standing type and the telescopic crown connection showed less stress concentration than the other specimen.
3. Although maximum fringe order was not equal, stress distribution of the specimen using rigid connector was similar with that of used telescopic connection. But of the showed even stress distribution at the natural tooth abutment and implant fixture.
4. In the specimen using non-rigid connector, more and wide stress distribution was seen around implant fixture comparing with the other specimen.
5. In case of connecting the implant and natural tooth abutment, using the telescopic crown connection is adventageous in stress distribution, and manintenance of prothesis because of easy removal and reinsertion.
