A clinical study on osseous regeneration in the jaw defects using a composite of coral and bone marrow / 医学研究生学报

ABSTRACT

Objectives:To evaluate the efficiency of packing jaw defects with a composite of coral and bone marrow.　Methods:Twelve patients (9 with jaw cyst and 3 with ameloblastoma) underwent enucleation of jaw lesion and packing with a composite of coral and bone marrow.Repair of the bone defects was evaluated at 1 week,1,6 and 12 months postoperatively by clinical examination and X-ray films.　Results:Wound healing after the operations on 10 patients was uneventful,and definite ossification around the implanted material could be detected at 1 month postoperatively.A lot of bone formation and partial resorption of coral were observed at 6 months postoperatively.Complete resorption of coral and complete bone repair were obtained at 12 months postoperatively.Wound breakdown was observed on two other patients,and the composite had to be removed completely.　Conclusions:A composite of coral and bone marrow may enhances bone healing in jaw defects after cyst or ameloblastoma removal.
