This often requires sinus floor elevation and bone grafting prior to implant placement. Techniques such as the lateral window approach and osteotome-mediated sinus floor elevation aim to achieve sufficient vertical bone height for successful implant placement.\n\nAutogenous bone grafts have long been considered the gold standard; however, their use is associated with limitations including donor site morbidity and graft volume loss, which has encouraged the exploration of alternative grafting materials. Sticky bone is a term used in oral surgery and implantology to describe a cohesive, moldable, and adhesive bone graft material prepared by combining particulate bone graft material (xenograft) with biological additives such as Platelet-Rich Plasma (PRP) or Platelet-Rich Fibrin (PRF).\n\nPlatelet-Rich Fibrin (PRF), which is used in the present study, is an autologous leukocyte and platelet-rich fibrin matrix containing cytokines, platelets, and stem cells. PRF acts as a biodegradable scaffold that promotes microvascularization and guides epithelial cell migration. In addition, PRF may serve as a carrier for regenerative cells and allows sustained release of growth factors over a period ranging from one to four weeks, thereby enhancing the wound healing environment.\n\nObjectives:\n\nThe study aims to assess the clinical efficacy of sticky bone as a bone graft material in sinus lift procedures compared with conventional xenograft materials.\n\nMethods:\n\nA randomized clinical trial will be conducted comparing two groups: one receiving sticky bone with simultaneous implant placement and another receiving xenograft with implant placement. Preoperative assessment will include Cone Beam Computed Tomography (CBCT) imaging, followed by postoperative monitoring to evaluate bone height and implant stability.\n\nStudy Design:\n\nPatients fulfilling the inclusion and exclusion criteria will be recruited from the dental clinic. Written informed consent will be obtained from all participants after explanation of study procedures, potential risks, and expected benefits. Eligible patients will be randomly allocated into two equal groups using a computer-generated randomization program: Group 1 (Sticky Bone group) and Group 2 (Xenograft group).\n\nStatistical Analysis:\n\nSample size calculation was performed using G\\*Power software version 3.1.9.7. The statistical test family selected was the t-test. Based on data from a previous study, a total of 16 participants were required to achieve a study power of 80% with a significance level (alpha) of 0.05. To compensate for potential dropouts, the total sample size was increased to 18 participants (9 patients per group).",[63,64,65],"Sinus Lifting","Dental Implant","Sticky Bone",[67,68,69,70,71],"Dental implants","sticky bone","bone graft","sinus lift","PRF","NOT_YET_RECRUITING","2026-05-21",{"date":75,"type":76},"2026-05-26","ACTUAL",{"date":78,"type":57},"2026-06-01",{"date":80,"type":57},"2027-04-01",{"name":5,"class":6}]
