Severely resorbed mandible: predictable reconstruction with soft tissue matrix expansion (tent pole) grafts.

Purpose: Attempts to reconstruct the severely resorbed mandible (
Material And Methods: A novel surgical approach using dental implants as "tent poles," along with bone grafting, is described, and the long-term follow-up of 64 cases is presented.

Results: The results revealed that all 64 grafts maintained 15 mm of bone height, with a follow-up ranging from 3 to 10 years and a mean follow-up of 4.9 years. The starting bone heights ranged from 3 to 6 mm, with a mean height of 4.8 mm. The mean bone height gain was 10.2 mm, with a range of 9 to 13 mm. All patients progressed to a functional denture that remained in function at the time of their follow-up. Short-term paresthesia (or=3 years).

Conclusions: The novel strategy of this surgery whereby bone grafts consolidate and maintain their volume by dental implants that creates a tenting effect offers predictable long-term reconstruction of the severely resorbed mandible without the complications observed with other approaches.
