The buccal fat pad – case reports

Introduction: The buccal fat pad is regularly used to reconstruct defects in the maxilla and to close oro-antral communications. One of its properties, the ability to convert free gingiva to keratinized mucosa, can be exploited to create beneficial conditions for peri-implant soft tissue.

Treatment method, case report 1: A 36-year old patient with insulin-dependent diabetes mellitus presented with complaints in the upper right quadrant. Tooth 16 was not worth preserving and was extracted, causing an oro-antral communication. The defect was successfully closed using a pedicled buccal fat pad flap.

Treatment method, case report 2: An oro-antral fistula was diagnosed in a 45-year old patient, persisting 6 months since extraction of the first left molar in the maxilla. After reconstruction of the bony defect using a bone block augmentation technique the soft tissue defect was reconstructed with the buccal fat pad to obtain adequate soft tissue width.

Results and discussion: The use of the buccal fat pad as a pedicled graft can be used reliably for the closure of oro-antral communications.

The use of allogeneic bone grafts for pre-implant alveolar ridge augmentation

Summary: Processed bone allografts (FDBA/DFDBA) are associated with a minimal risk of viral and non-viral transmission and do not trigger any clinically significant immune reaction. Clinical, histological and histomorphometric results in the literature and in our own experience are comparable to results with autologous bone grafts. The success of the clinically similar handling mainly depends on the soft tissue management. The main problem with both techniques is dehiscence, which may be positively influenced by resistant collagen barrier membranes. The unlimited availability, the avoidance of bone harvesting and the possibility of standardization and easy adjustment to the bone defect are major advantages in the case of severely resorbed alveolar ridges. In our opinion, processed bone allograft prior to implant placement is clinically equivalent to avascular autografts with far superior handling.
