目的：应用从种植截骨区取出的混合骨充填材料和自体骨碎屑，应用复合人工骨进行垂直牙槽骨扩弓，为牙槽骨萎缩的美容种植修复提供一例。材料：使用体积比为1：2：2的不可吸收和可吸收羟基磷灰石与脱矿冻干同种异体骨颗粒。钛微网用于牙槽骨形态和固位。术后8个月行种植体植入及种植体间植骨。结果：共完成了15 mm垂直和10 mm水平骨强化。随访4年后，负重病例的边缘骨高度和种植体周围粘膜保持稳定。结论：该方法在牙槽骨高度萎缩的美容种植修复中具有潜在的应用价值。
Purpose:To present a vertical ridge augmentation with a composite synthetic bone graft by the mixed bone-filling materials and autogenous bone chips retrieved from the implant osteotomy site for a case for esthetic implant prosthesis on the atrophied alveolar bone. Materials:Nonresorbable and resorbable hydroxyapatite and demineralized freeze-dried bone allograft particles were used at ratio of 1:2:2 (volume ratio). Titanium micromesh was used for alveolar ridge configuration and retention. After 8 months, implant placement and interimplant bone augmentation were performed. Results:15-mm vertical and 10-mm horizontal bone augmentation has been achieved. Marginal bone heights and periimplant mucosa remained stable in cases of loading after >4 years of follow-up. Conclusion:These results suggest that this method has the potential for use in esthetic implant rehabilitation on the highly atrophied alveolar bone.
