Abstract

BackgroundExtensive literature exists about the use of the BFP in the treatment of oral defects but, to our knowledge, no article refers to the use of the BFP as a substitute of the membrane barriers for treatment of peri-implant bone defects. The aim was to evaluate the use of the buccal fat pad as a coating material for bone grafting in the peri-implant bone defect regeneration of immediate implants placed in the posterior maxilla.Material and MethodsA preliminary prospective study of patients involving immediate implants in which the buccal fat pad was used as a coating material to peri-implant bone defects was carried out. The outcome measures assessed were: postoperative pain and swelling, complications related to buccal fat pad surgery, implant survival and success rates and peri-implant marginal bone loss at 12 months of prosthetic loading.ResultsTwenty-seven patients (17 women and 10 men) with a mean age of 55.3 ± 8.9 years, and a total of 43 implants were included. Two-thirds of the patients reported either no pain or only mild intensity pain and moderate inflammation, two days after surgery. Post-operative period was well tolerated by the patients and no serious complications occurred. None wound dehiscence occurred. Implant survival and success rates were 97.6% and the average marginal bone loss 1 year after loading was 0.58 ± 0.27 mm.ConclusionsWithin the limits of this preliminary study, the use of the buccal fat pad as a coating material for bone grafting in peri-implant bone defects placed in the upper posterior maxilla was a well-tolerated technique by patients; high implant success rate was achieved with a minimal peri-implant marginal bone loss at 12 months of prosthetic loading. Key words:Buccal fat pad, immediate implant, peri-implant bone defect.

Highlights

Implants placed into extraction sockets have been shown to be a successfully predictable treatment modality [1]
The aim of the study was to evaluate the use of the buccal fat pad as a coating material for bone grafting in the peri-implant bone defect regeneration of immediate dental implants placed in the posterior maxilla
Material and Methods The present study is reported in accordance with the STROBE statement for strengthening the reporting of observational studies [24]. - Patient Selection We conducted a preliminary prospective clinical study involving patients with peri-implant buccal bone defects after receiving immediate implant placement in the posterior maxilla, treated with simultaneous particulate bone grafting and were the buccal fat pad was employed as a coating material

Summary

Introduction

Implants placed into extraction sockets have been shown to be a successfully predictable treatment modality [1]. The aim of the study was to evaluate the use of the buccal fat pad as a coating material for bone grafting in the peri-implant bone defect regeneration of immediate dental implants placed in the posterior maxilla This was done by assessing the postoperative pain and swelling, complications related to the fat pad technique, implant survival, implant success, and radiographic periimplant marginal bone loss at 12 months of prosthetic loading. Conclusions: Within the limits of this preliminary study, the use of the buccal fat pad as a coating material for bone grafting in peri-implant bone defects placed in the upper posterior maxilla was a well-tolerated technique by patients; high implant success rate was achieved with a minimal peri-implant marginal bone loss at 12 months of prosthetic loading
