This case report aimed to describe the effects of leukocyte and platelet-rich fibrin (L-PRF) associated with deproteinized bovine bone mineral (DBBM) and absorbable collagen membrane (CM) on bone regeneration in maxillary sinus augmentation. A 59-year-old male patient was referred to the Department of Periodontology for implant rehabilitation of his edentulous upper jaw. The treatment plan involved maxillary sinus augmentation followed by implants installation. A split-mouth design was employed, in which the right maxillary sinus was filled using L-PRF, DBBM, and CM; the left side was filled with DBBM and CM...

The guided bone regeneration (GBR) technique is often applied to provide sufficient bone for ideal implant placement. The objective of this study was to evaluate whether GC membrane®, which has already been used for guided tissue regeneration (GTR), can also be available for GBR. Twenty-three implants in 18 patients were evaluated in the study. All patients underwent implant placement with GBR using GC membrane®. Cone-beam computed tomography was performed at 13-30 weeks after surgery and the amount of augmented bone was assessed...

Immediate implants are a valuable treatment option to replace natural teeth in the aesthetic region. The hypothesis of this randomized controlled clinical trial was that immediate implants grafted with autologous platelet-rich fibrin (PRF) have better clinical and radiographic outcomes than non-grafted controls. Forty-one implants were placed in 31 subjects with one or more non-restorable single-rooted teeth. Autologous PRF was placed in the peri-implant region of the study group (n=21) and no augmentation was done in the control group (n=20)...
