Objective: The purpose of the experiment is to investigate the possibility of implanting polymethylmethacrylate (PMMA) to reconstruct the alveolar bone defect after teeth extraction or radicular cyst extirpation.

Autogenous bone mesenchymal cells collagen membrane in repair of critical size cancellous bone defect;

Cancellous bone defects were created on bilateral femur condylar in 15 Japanese big ear rabbits,the left bone defects were treated with allogenic MSCs and fibrin,the right were treated with fibrin only.

Objective To evaluate X-ray and CT diagnostic value of fibrous cortical defect(FCD).

Tooth movement after restoration for alveolar bone defect with BMSC HA/TCP scaffold;

Biomechanical Evaluation on Bone Defect Repairing with Porous Carbonate Calcium Ceramics;

Effects of vascular endothelial growth factor for repairing bone defect;

Clinical application of injectable calcium sulfate with vacuum mixing for grafting bone defects;

The mechanism of repair segmental bone defects with high energy shock waves;
