| Research Abstract |
Alveolar ridge tends to absorb by periodontal diseases or aging, and its augmentation technique is required in many cases before dental implantation. However alveolar ridge augmentation is not an easy surgery. The purpose of this study was to evaluate the best material or method to reserve a required space for periosteum augmentation. We used PLLA/PLGA membrane as the periosteum lifting auto-swelling material on rat calvaria model. As a temporary insertion usage, the membrane should be removed within 3 weeks before its self resorption. Interestingly, ectopic bone formations in the PLLA/PLGA membrane were observed after 9 week. Insertion of PLLA/PLGA membrane underneath the periosteum might be an alternative method for alveolar ridge augmentation.
