Three months after teeth extraction, two implant sites were bilaterally drilled, buccal bone dehiscences were created and four titanium implants were placed. Dehiscences were randomly assigned to the following groups: (1) PRP, (2) GBR, (3) PRP+GBR and (4) control. After 3 months, the animals were sacrificed and the implants and adjacent hard tissues were processed for undecalcified sections. Bone\u2010to\u2010implant contact (BIC), bone density within the limits of implant threads (BW), bone density (BD) and new bone area (BA) in a zone lateral to the implant corresponding to bone defects were obtained and measured.<\/jats:p><jats:p><jats:bold>Results: <\/jats:bold> Intergroup analysis (two\u2010way ANOVA \u2013\u03b1=5%) demonstrated that when PRP was utilized,no differences were observed for all parameters (<jats:italic>P<\/jats:italic>&gt;0.05).
