In the control group, autogenous bone was used to cover the exposed implant surface then a layer of deproteinized bovine bone mineral (DBBM) was added. This graft combination was then combined with a collagen membrane. In the test group, the exposed implant surface was covered with a layer of freeze\u2010dried bone allograft (FDBA) in combination with the collagen membrane. Modified plaque index (mPI), modified sulcular bleeding index (mSBI), probing depth (PD), keratinized mucosa (KM), implant crown length (IC), distance from the implant shoulder radiographic bone\u2010to\u2010implant contact (DIB), pink esthetic score (PES), and white esthetic score (WES) were measured at 12\u2010months post implant loading.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All 48 implants were clinically successful, and no significant differences were observed in mPI, mSBI, PD, KM, IC, DIB, PES, and WES at 1\u2010year implant loading.
