One of the key factors affecting the long-term success of dental implants is the stability of the bone surrounding the implant, particularly the crestal bone around the implant neck. Implant insertion depth relative to the alveolar crest may influence peri-implant tissue health and marginal bone remodeling.\n\nThis randomized controlled clinical trial aims to evaluate the influence of implant placement depth on peri-implant health and radiographic bone changes around short dental implants placed using guided surgical protocol. All implants will be placed using the Bicon Implant System following computer-guided implant planning and surgical guide fabrication to ensure precise implant positioning.\n\nParticipants requiring implant therapy will be randomly allocated into two groups. In the test group, implants will be placed 2 mm below the crestal bone level (subcrestal placement). In the control group, implants will be placed at the crestal bone level (crestal placement). Implant placement will be performed using guided implant surgery to standardize surgical positioning and minimize variability in implant angulation and depth.\n\nClinical parameters related to peri-implant health, including Modified Plaque Index, Implant Mucosal Index, Peri-implant Mucosal Tissue Index and Probing Depth during follow-up visits at 3, 6 and 12 months. In addition, standardized radiographic examinations will be performed to measure peri-implant Crestal bone level changes at 12 months.\n\nThe primary objective of this study is to determine whether subcrestal implant placement (2 mm below the bone crest) results in improved preservation of peri-implant crestal bone compared with crestal implant placement. Secondary outcomes will include assessment of peri-implant soft tissue health and overall implant stability.\n\nThe findings of this study may help clarify the optimal implant insertion depth for short implants placed using guided surgery and may contribute to improving long-term implant success and peri-implant tissue stability.",[85,86,87],"Tooth Loss","Edentulism","Peri-implant Bone Loss",[89,90,91,92,93],"Dental Implants","Short Implants","Subcrestal Implant Placement","Peri-Implant Health","Radiographic Bone Changes","NOT_YET_RECRUITING","2026-03-09",{"date":97,"type":98},"2026-03-13","ACTUAL",{"date":100,"type":79},"2026-03-30",{"date":102,"type":79},"2027-05-30",{"name":5,"class":6},1]
