There may be complications such as bleeding, pain, swell, dry socket, and etc, which will affect the daily life of patients. The rebuilding and absorption of alveolar bone and the reduction of bone after extraction cause the unsatisfactory clinic repair effects.

Variant acellular dermal matrix takes off all the cells of the variant epidermis and dermal, reserves the structure of acellular dermal matrix, and well preserves the basal membrane between the epidermis layer and dermal layer. The peculiar features of acellular dermal matrix include: 1. good biological compatibility; 2. collagen three-dimensional structure helping cells to move and multiply; 3. collagen,...
