Immediate nonfunctional loading of implants placed simultaneously using computer-guided flapless maxillary crestal sinus augmentation with bone morphogenetic protein-2/collagen matrix
Clinical Implant Dentistry and Related Research Aug 16, 2019
An X, et al. - In this investigation, researchers assessed the impacts of simultaneously placed immediate non-functional loaded implants and bone morphogenetic protein-2 (BMP-2)-loaded Bio-Oss collagen, on bone formation and implant stability in patients with a severely atrophic posterior maxilla using crestal approach during the early healing stages. They assessed 33 cases presenting posterior maxillary residual alveolar bone height of 1-3 mm. Using preoperative and postoperative cone beam computed tomography, the bone height was evaluated. According to findings, the implant survival rate was 100% and the implant gingiva stayed healthy. All implants stayed integrated, and radiographic bone formation was demonstrated by all sinus grafts. The findings showed elevated bone density levels and excellent implant stability, resulting in minimal marginal bone loss after 37.3 months. In the posterior maxillary region exhibiting poor bone quantity, this technique could be used.
