Purpose: This is the review the prognosis of dental implants placed in the autogenous bone grafted mandibular bed without or with myocutaneous flaps. Materials and Methods: Tomor ablative surgery was undertaken in their mandible of twelve patients (7 males and 5 females) visited Ewha Medical Center from 1990 November to 1998 June. The mandibular defect was reconstructed by autogenous bone without or with myocutaneous flap and rehabilitated by implant-supported prostheses. All thirty-eight implants on grafted autogenous bone were monitored for over one year up to 7 years, with periodical radiographic check-up and perio-test. Results: Density of grafted bone was found as Type 2-3 in 92.1%. Fixtures used comprised of Branemark 13.2%, 3i 29.0%, ITI 18.4% and Dentsply 39.4%. Fixtures of 10-13 mm length had been used most frequency in 86.8%. Peri-implant soft tissue management was required in 75% of the cases. Loss of peri-implant crestal bone was less than 1 mm in 92.1%. All implants survived over one year up to 7 yeas. Conclusion: All implants placed on grafted autogenous bone survived, irrelevant to the type and length of any implants. This indicates that dental implants placed in autogenous bone-grafted beds support effectively mandibular rehabilitated prosthesis.
