Abstract:

BACKGROUND: Acellular dermal matrix has good biocompatibility and absorbability and exhibits superiority in the guided bone regeneration.
OBJECTIVE: To compare the histological changes and osteogenic effects in bone defects after guided bone regeneration with acellular dermal matrix and Bio-Gide membrane.
METHODS: Mandibular second, third and fourth premolars and the first molars bilaterally were extracted from 12 beagle dogs. Three months later, four three-wall bone defect models in the mandible of each dog were made, and randomized into acellular dermal matrix plus bone graft group (acellular dermal matrix group), Bio-Gide plus bone graft group (Bio-Gide group), bone graft group, and blank control group (no treatment). In the former two groups, acellular dermal matrix and Bio-Gide were used to cover the bone grafts, respectively.
RESULTS AND CONCLUSION: After surgery, all the beagle dogs recovered well. All the groups except the control group showed dramatical improvement in histological changes and percentage of new bone area, and this improvement was more significant in the Bio-Gide and acellular dermal matrix groups. Moreover, there was no significant difference between the Bio-Gide and acellular dermal matrix groups. Therefore, the acellular dermal matrix can be a candidate for bone repair instead of Bio-Gide membrane in the clinical practice.
