The autogenous bone core block (BCB) is a viable, biologically advantageous, and minimally invasive alternative to other augmentation procedures for small bone defects around dental implants. This study focused specifically on horizontal vestibular defects in the mandible, a frequently encountered yet underrepresented clinical situation, to evaluate the effectiveness and predictability of bone core grafting. Cylindrical autogenous bone cores, harvested from the implant-site osteotomy using trephine drills with a 2.5 internal diameter, were stabilized with osteosynthesis screws, and implants were placed simultaneously. Initial preoperative measurements of the edentulous ridge width were performed based on cone beam computer tomography (CBCT). At 4 months postoperatively, a subsequent CBCT measurement was performed for each implant site. A total of 38 augmentation procedures were analyzed with a mean horizontal bone gain of 1.8 mm ( = 0.000). Improved outcomes were observed in V-shaped defects with remaining vertical bony walls, which contributed to better graft stability and volume preservation. While Khoury et al. previously validated the general applicability of this technique across various defect types, our study refines its indication by offering a clear protocol tailored to a common clinical niche. The proposed BCB method proved to be a safe, efficient, and with reduced morbidity procedure, providing clinicians with a practical and evidence-based tool for predictable horizontal bone augmentation.
自体骨芯块(BCB)是一种可行的、具有生物学优势且微创的方法,可替代用于牙种植体周围小骨缺损的其他增量手术。本研究特别关注下颌骨水平前庭缺损这一常见但研究较少的临床情况,以评估骨芯移植的有效性和可预测性。使用内径为2.5的环钻从种植体部位截骨处获取圆柱形自体骨芯,用骨合成螺钉固定,并同时植入种植体。基于锥形束计算机断层扫描(CBCT)对无牙嵴宽度进行术前初始测量。术后4个月,对每个种植体部位进行后续CBCT测量。共分析了38例增量手术,平均水平骨增量为1.8毫米( = 0.000)。在有剩余垂直骨壁的V形缺损中观察到了更好的结果,这有助于提高移植稳定性和保持骨量。虽然Khoury等人此前已验证了该技术在各种缺损类型中的普遍适用性,但我们的研究通过提供针对常见临床情况的明确方案,进一步细化了其适应证。所提出的BCB方法被证明是一种安全、高效且发病率较低的手术,为临床医生提供了一种实用且基于证据的工具,用于可预测的水平骨增量。
