Objective:To evaluate the method of prosthesis about the fixed partial denture which the tilted molar used as a abutment. Methods:A screw-connected fixed partial denture was used in 32 outpatients whose abutments were tilted

and the effect of prosthesis was observed. Results:After 1～2.5 years

29 outpatients ( 90.6%) were visited . All of prosthesis were successful except for 2 cases. The rate of success was 93.1%. Conclusion : It is a good method that a screw-connected fixed partial denture can be used when the tilted molar played a part of a abutment。
