buccal-lingual
1.Conclusion: It is feasible using designed buccal-lingual rest in repairing removable partial denture.
2.Results: Of the 84 cases,66 had successfully used buccal-lingual rest for three years and 5 were fail.
4.Methods: This experiment was carried out by using a seperate human mandible. Five clasp designs were examined in this experiment,including RPA, RPI, modified RPI (mRPI), three-arm clasps and buccal wrought wired three-arm clasps. Hologramatic measurement was applied to record the different effects of these five designs of clasps on buccal and lingual alveolar bone.
