Abstract
Clinical study on immediate reconstructions of mandibular defect with various reconstructive materials following mandibular resection were carried out in 32 cases during the past 8 years. The materials for mandibular reconstruction was A-O plate 24, iliac bone 6 and alumina ceramics 2.
1) A-O plate seemed to be a useful material as it could be available regardless of the extent of bone defect. However, the complications occurring in some cases increased when it was placed in long-term.
2) Application of iliac bone graft was limited in the defect size. However, it could recover the oral dysfunction and esthetic disturbance. Therefore it was useful as an eternal reconstructive material
3) Alumina ceramics was weak in strength and it was an inconvenient material because its form could not be modified during operation. However it proved to be superior to A-O plate in recovering the facial contour.
