CLINICAL AND RADIOGRAPHIC ASSESSMENT OF BOND APATITE IN HORIZONTAL BONE AUGMENTATION AROUND DENTAL IMPLANTS: A RANDOMIZED CONTROLLED TRIAL

Background:Bond apatite is a composite graft, composed of two-thirds biphasic calcium sulfate and one-third hydroxyapatite granules of various sizes and shapes. Oral implants are used to secure dental prostheses in cases of partial or total edentulism. The outcomes of correctly completed dental-implant procedures result in high rates of success and survival of dental prostheses. Objective:The aim of this study was to assess Bond Apatite use in horizontal bone augmentation around dental implants, clinically and radiographically. Materials and Methods:This research included sixteen patients, six men and ten women, with an average age of thirty years having missing maxillary anterior or premolar teeth with insufficient horizontal bone. The patients were divided into two groups: group I patients (N=8) received dental implants with Bond apatite, while group II patients (N=8) received dental implants with Bio-Oss bone graft material and pericardium bioresorbable membranes. All patients were evaluated clinically usingthe modified plaque index (MPI), modified gingival index (MGI) and probing depth (PD) and radiographically to assess bone width dimensions. Results: There was a statistically significant difference between groups regarding MGI(p = 0.038)andperi-implant buccal PD [mm](p = 0.026). There was no statistically significant difference between the tested groups regarding age(p = 0.608), sex(p = 0.123), MPI(p = 0.608),orperi-implant palatalPD [mm](p = 0.118). There was no statistically significant difference between the two groups regarding postoperative bone width (p = 0.187). Conclusion:Bond apatitemay be used as one of the materials of choice for horizontal bone augmentation around dental implants with similar promising results compared to Bio-Oss. Finally, the use of Bond apatite preparation is a straightforward, affordable, and considered successful bone graft material that could be used in osseous defect reconstruction procedure. Trial registration:The study is listed on www.clinicaltrials.gov with registration number (NCT06043258) 22/09/2023. The study was conducted in accordance with the seventh revision of the Helsinki Declaration in 2013 and approved by the Institutional Review Board (IRB) (M07061119) of the Faculty of Dentistry, Mansoura University, Egypt.
