Migration of epithelial cells on materials used in guided tissue regeneration.

abstract：BACKGROUND AND OBJECTIVE:Following tooth extraction, bone resorption is especially severe in cases complicated with buccal dehiscence bone defects. To minimize this, various bone graft materials have been used for alveolar ridge preservation. This study aimed to evaluate additional effects of the concomitant use of rec...
