하악골 부분 절제술후 metal plate와 PMMA를 복합 이용한 하악골 재건술의 치험례

MANDIBLE RECONSTRUCTION WITH THE COMBINATION OF METAL PLATE AND RADIOPAQUE PMMA AFTER PARTIAL MANDIBULECTOMY : Report of 2 cases

This is a report of two cases of immediate reconstruction after partial mandibulectomy by using of metal plate and radiopaque polymethylmethacrylate (PMMA, Bone cements？？) in the cases of an ameloblastoma and a dentigerous cyst with epithelial dysplasia on the mandible. We could get many advantages and the results are as follows. 1. It provided good esthetics and stress bearing area for partial denture reconstruction by the reconstruction of adequate volume and shape as its origin. 2. Because of the direct fusion of radiopaque PMMA to bone, the fixation and stability were more increased than used metal plate only. And so, IMF period was saved and masticatory function was returned in short period. 3. Alloplastic reconstruction was possible without any positional change of TMJ. 4. Post-op radiologic evaluation was easily possible in position and volume due to PMMA s radiopaque characteristics. 5. Long-term follow-up evaluation may be necessary in concerned with the histompatability of this alloplastic material.
