Background:
Resection of mandibular tumors without proper reconstruction may lead to unfavorable esthetic and function results. The purpose of this case series was to describe clinical results and a technique to prevent tissue loss using nonvascular iliac grafts immediately following tumor resection and long-term stability of the implants.
Materials And Methods:
Three female patients presented with oral neoplasms (2 ameloblastoma and 1 ossifying fibroma). The mandibular reconstruction was performed with nonvascularized iliac grafts simultaneous with tumor removal. Subsequently, 10 dental implants were placed 6 to 9 months after reconstruction and restored. Survival and success of the implants were evaluated.
Results:
Marginal mandibulectomy in 1 patient and buccal bone resection in 2 patients was performed; the resection sites were reconstructed with an immediate nonvascularized iliac graft. All implants survived and were successful during follow-up periods between 44 and 105 months. Mean marginal bone loss of 10 implants was 0.09 mm.
Conclusions:
Immediate reconstruction with nonvascularized iliac grafts following tumor resection may be a viable treatment option for nonsegmental inlay osseous defects. In these case series, the resorption of the iliac bone was minimal after 6 to 9 months consolidation periods.
