Purpose : The purpose of this study is a finite element analysis of supporting bone according to custom abutment angle Methods : Implant fixture was selected with a diameter of 4 ㎜ and the length of 13 ㎜. The fixture and abutment was designed by a combination of the abutment screw clamping force to produce a custom abutment model of 0°, 15°, 25° and 35°. The loading condition of 176 N was applied to the lingual surface of the crown, near to the incisor edge, and horizontal load. An oblique load of 90° was applied long axis of the implant fixture analyze the stress of supporting bone. Results : The result of mechanical analysis was observed that the supporting bone stress analysis of the horizontal load, the von Mises stress values (㎫) are given in the order of TH00 (432.6) > TH25 (418.0) > TH15 (417.4) > TH35 (415.8) , the oblique load, the von Mises stress values are given in the order of TO00 (459.3) > TO15 (399.6) > TO25 (374.8) > TO35 (343.4) Conclusion : The 35° abutment over the current clinical tolerance limits will be available for clinical application.
