IMMEDIATE REPLACEMENT OF MANDIBULAR DEFECTS FOLLOWING TUMOR RESECTION

Mandibular defects caused by tumor resection, infection and trauma have resulted in manidbular deviation, atrophy of mastricatory muscle and contracture of soft tissue, and so is further complicated by facial deformity and functional disturbance. Because of such a functional and esthetic reasons, needs for the replacement of mandibular defect immediately after the resection of mandible were emphasized. Until now, it is well known that the most favorable replacement material is autegenous bone, but has some technical difficulties and contraindications for it s use in the treatment of malignant tumor. Prosthetic implant materials have many advantages over the bone graft tn view of stability, need for radiation therapy and adjustability, etc. We have obtained favorable results by replacing the mandibular defect with stainless steel metal reconstruction plate and heat curing acrylic resin implant functionally and esthetically.
