Abstract

Purpose: To histologically and radiographically compare the newly formed bone (NFB) yielded following sinus floor augmentation using bone marrow aspirate concentrate (BMAC) loaded on bovine bone graft versus bovine bone graft. Methods: The current randomized clinical trial included ten patients with maxillary posterior atrophy who were presented at outpatient’s clinic of the faculty of dentistry, Cairo university. NFB was histologically assessed 4 months following sinus augmentation using BMAC/ deproteinized bovine bone (DBB) (study) versus DBB graft (control). Covariates included residual ridge height, age and sex. At second stage surgery (after 4 months) core biopsies were harvested and submitted for histologic analysis. Results: The sample included 10 eligible patients with mean age of 46.8 years. Both groups showed thin irregular bone trabculae with intervening wide bone marrow spaces, areas of woven bone and material remnants were observed. Higher magnification revealed a high inflammatory cell infiltration in contol group). Moreover, radiographic bone height on CBCT for the study group (13.34±2.76) was higher than that of the control group (10.10±2.46) after 4 months (p>0.05). Conclusions: BMAC /DBB yielded comparable bone gain to the control group. BMAC utilization for sinus floor augmentation supported healing and maintained the grafted sinus height.
