Background Mandibular continuity defects occur after tumor resection, maxillofacial injury, or osteomyelitis. Despite the current availability of a plethora of treatment modalities, bone substitutes, and various clinical adjuncts, an exact reconstructive recapitulation of large bony defects continues to be beyond reach. In this clinical pilot study, we report a novel method for reconstruction ...

BACKGROUND It has been studied that the distribution of bone morphogenetic protein 2 is regular under bone defect situation. OBJECTIVE To observe the expression of bone morphogenetic protein 2 in rabbit radial defect site with different lengths. METHODS Forty-eight New Zealand rabbits were divided into two groups randomly. 0.5 cm bone defect and 3.0 cm bone defect were made by wire saw at t...
