An insufficient volume of the alveolar bone may prevent implants from being placed in the prosthetically optimal position. Complex restoration of bony structures is required to achieve long-term peri-implant bone stability and represents an adequate prosthetic solution. : The shell technique has become a widespread and important method for guided bone regeneration in dentistry. Allogeneic bone materials appear to be the most similar substitution for autogenous bone transplants. However, there are few studies using cortical bone allografts in combination with a mix of autogenous and xenograft materials for the augmentation of horizontal ridge defects. This combination offers the advantage of reduced patient morbidity while adding adequate volume and contour to the alveolar ridge. : The present case study aimed to clinically and radiographically evaluate the efficacy of allogenic cortical bone lamina combined with a composite bone graft in the augmentation of a horizontal bone defect in the edentulous maxilla during a 6-year follow-up period. Three CB CT scans taken before treatment, 6 months after the augmentation period/before implant placement, and after a 6-year follow-up period, were analyzed using stable referent points. After the 6 -year follow-up period, the average resorption rate was 21.65% on the augmented buccal side, with no implant exposure being observed. : The bone shell technique used in conjunction with allogenic bone plates combined with autogenous bone, xenografts, and collagen membranes is an effective technique to manage horizontal ridge defects.
牙槽骨量不足可能会妨碍将种植体放置在最佳的修复位置。为了实现长期的种植体周围骨稳定性，需要对骨结构进行复杂的修复，这代表了一种合适的修复解决方案。：壳技术已成为口腔医学中引导骨再生的广泛而重要的方法。同种异体骨材料似乎是自体骨移植最相似的替代品。然而，很少有研究使用皮质骨同种异体移植物与自体和异种移植物材料的混合物来增加水平牙槽嵴缺损。这种组合的优点是减少了患者的发病率，同时为牙槽嵴增加了足够的体积和轮廓。：本病例研究旨在通过临床和影像学评估在 6 年的随访期内，使用同种异体皮质骨板联合复合骨移植物对无牙上颌骨水平骨缺损进行增强的效果。在治疗前、增强期/种植体放置前 6 个月和 6 年随访期后，使用稳定的参考点对 3 次 CB CT 扫描进行分析。在 6 年随访后，增强颊侧的平均吸收率为 21.65%，未观察到种植体暴露。：联合使用同种异体骨板和自体骨、异种骨和胶原膜的骨壳技术是一种有效的方法，可用于治疗水平牙槽嵴缺损。
