Ojective To evaluate the effect of implatation of prosthesis under the periosteum via oral incision on mentoplasty. Methods The buccal morphology and structure of cadaver was studied with topographic methods. 43 cases of mentoplasty was treated by implatation of prosthesis under the periosteum via oral incision. Results The mandibular shape of all cases treated by mentoplasty were improved with successful and satisfactory effects. No complication occurred. Conclusions It suggested that the implatation of prosthesis under the periosteum via oral incision was a safe, effective procedure for mentoplasty.
