In the internal connection system, the loading transfer mechanism within the inner surface of the implant and also the
stress distribution occuring to the mandible can be changed according to the abutment form. Therefore it is thought to be
imperative to study the difference of the stress distribution occuring at the mandible according to the abutment form. The
purpose of this study was to assess the loading distributing characteristics of three different abutments for GS II¨Þ implant
fixture(Osstem, Korea) under vertical and inclined loading using finite element analysis. Three finite element models were
designed according to three abutments; 2-piece TransferTM abutment made of pure titanium(GST), 2-piece GoldCastTM
abutment made of gold alloy(GSG), 3-piece ConvertibleTM abutment with external connection(GSC). This study simulated
loads of 100N in a vertical direction on the central pit(load 1), on the buccal cusp tip(load 2) and 30¡Æ inward inclined
direction on the central pit(load 3), and on the buccal cusp tip(load 4). The following results were obtained. 1. Without regard to the loading condition, greater stress was concentrated at the cortical bone contacting the upper part of the implant fixture and lower stress was taken at the cancellous bone. 2. When off-axis loading was applied, high stress concentration observed in cervical area. 3. GSG showed even stress distribution in crown, abutment and fixture. GST showed high stress concentration in fixture and abutment screw. GSC showed high stress concentration in fixture and abutment. 4. Maximum von Mises stress in the surrounding bone had no difference among three abutment type.
In GS II¨Þ conical implant system, different stress distribution pattern was showed according to the abutment type and
the stress-induced pattern at the supporting bone according to the abutment type had no difference among them.
