Flapless crestal sinus augmentation surgery was performed using BMP\u20102\u2010loaded Bio\u2010Oss collagen, with non\u2010functional implants immediately loaded after surgery. The bone height was assessed using preoperative and postoperative cone beam computed tomography (CBCT). Bone density of the sinus graft sites and implant stability (after 3\u2009months) were evaluated using postoperative CBCT scans and Periotest, respectively. The periodontal parameters and marginal bone loss around the implant were checked after 37.3\u2009months of final prosthesis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The survival rate of the implants was 100% and the gingiva around the implants remained healthy.
