Abstract

Aim: This study designed to compare clinically and radiographically between
Platelet Rich Fibrin (PRF) membrane and collagen membranes in combination
with Beta tri calcium phosphate βTCP/collagen in treatment of dehiscence around
immediately placed dental implant. Subjects and methods: This study was performed
on 20 sites from 20 patients who each received an immediate implant for a single tooth
replacement at a maxillary anterior or premolar site. Patients were divided into two
groups according to the augmented materials used. One group received an immediate
implant and filling of defects using Beta Tri Calcium Phosphate/Collagen bone graft
covered with PRF membrane. The other group received an immediate implant and filling
of defects with Beta Tri Calcium Phosphate/Collagen covered with collagen membrane.
Cone beam computed tomography (CBCT) was taken before placement, and at 6 and
12 months post-surgery. Results: Both treatment procedures resulted in significant
improvements for the primary outcome regarding bone fill as well as thickness and
height of buccal bone. In addition, statistically significant differences were found in
the buccal bone height, thickness and bone density for the group treated with Beta
Tri Calcium Phosphate/Collagen combined with collagen membrane compared with
sites treated with Beta Tri Calcium Phosphate/Collagen combined with PRF membrane
.Conclusion: Beta Tri Calcium Phosphate/Collagen combined with collagen membrane
is significantly superior than Beta Tri Calcium Phosphate/Collagen combined with PRF
membrane in treatment of buccal bone dehiscence during immedite implant placement
