BACKGROUND:Prefabricated customized bone flaps have the advantages of few trauma, good vascularization, ossification with predetermined shape, and can be used to restore bone defects with compromised blood bed.
OBJECTIVE:To establish animal models of mandibular reconstruction with prefabricated, customized bone flaps.
METHODS:After computed tomography scanning of nine rhesus’ head, customized meshes were made. After loading with recombinant human bone morphogenetic protein-2-incorporated demineralized freeze-dried bone al ograft (DFDBA) or coral ine hydroxyapatite (CHA), the constructs were implanted in latissimus dorsi muscle. Meanwhile, segmental mandibular defects were created, and the customized meshes loaded with DFDBA, CHA, or recombinant human bone morphogenetic protein-2-incooperated DFDBA and CHA were implanted in situ. At 13 weeks, prefabricated bone flaps with recombinant human bone morphogenetic protein-2-incorporated DFDBA or CHA were transferred to repair segmental mandibular defects. Clinical and histological analyses were used to evaluate the ossification and vascularization of the prefabricated implants in ectopic and orthotopic sites.
RESULTS AND CONCLUSION:Segmental mandibular defects were successful y restored with prefabricated bone flaps and recombinant human bone morphogenetic protein-2-incorporated CHA in situ, but other segmental mandibular defects remained with recombinant human bone morphogenetic protein-2-incorporated DFDBA, DFDBA and CHA in situ. Moreover, mandibles reconstructed with prefabricated bone flaps revealed more regenerated and homogeneous bone formation than other reconstructions. These findings suggest that the animal model of mandibular reconstruction with prefabricated, customized bone in rhesus monkey is applicable.

BACKGROUND:Alveolar distraction osteogenesis is an important method for treating alveolar bone atrophy, the osteogenesis process and biomechanics play a crucial role in the fol owing implantation and repair. At present, no related experimental studies are found.
OBJECTIVE:To analyze the biomechanical and histological characteristics of alveolar distraction osteogenesis in a canine model.
METHODS:Twelve adult mongrel canines received premolars extraction and alveoloplasty in mandible to establish an atrophy alveolar model. After 3 months, a segmental alveolar osteotomy was performed in the randomly selected unilateral atrophy alveolar and two intra-osseous distractors were placed. After a 7-days latency period, the alveolar ridge was augmented at a rate of 1.0 mm/d for 5 days. After a consolidation of 1, 2, and 3 months, the canines were sacrificed and the specimens of the distracted alveolar bone were harvested for clinical, radiographic, histological and biomechanical analysis.
RESULTS AND CONCLUSION:The alveolar distractors obtained good healing with surrounding tissue. The atrophy alveolar bones were augmented for (4.80±0.50) mm and (5.12±0.47) mm by clinical and radiographic findings immediately after distraction, respectively. The bone trabeculae in the distracted chamber matured from 1 to 3 months of consolidation by histological analysis. The shearing force of alveolar distraction chamber increased from 1 to 3 months. After 3 months’ consolidation, the shearing force of distracted chamber was comparable to host bone. The histological and biomechanical property of distracted alveolar chamber is comparable to host bone after 3 months’ consolidation.
