Abstract
OBJECTIVES: Rehabilitation of edentulous ridges to promote the insertion of dental implants has been the key indicator for retaining osseous structures since tooth extraction. Recombinant Bone Morphogenetic Protein-2(rhBMP-2) is exploited for bone augmentation due to its osteoinductive capacity. The objective of the study to determine the effectiveness of bone induction for implant placement by rhBMP-2 delivered on beta-tricalcium phosphate graft (β-TCP) and PRF following tooth extraction. RESULTS: Minimal changes in the width of the crestal bone relative to baseline values were found three months after socket grafting. A bone loss in the mesiodistal and buccolingual aspects of 0.6 ± 0.13 mm and 0.5 ± 0.13 mm was found, respectively. While drilling before the implant placement, the bone's clinical hardness evaluated through tactile was analogous to drilling into spruce or white pine wood. Total radiographic bone filling was seen in 3 months and no additional augmentation was needed during implant placement. Besides, histology shows no residual graft of bone particles. Therefore, the data from this study demonstrated that the novel combination of rhBMP-2 + β-TCP mixed with PRF has an effect on de novo bone formation and can be recommended for socket grafting before implant placement.
