This prospective case series evaluated the use of a new synthetic resorbable membrane with autogenous bone, either alone or in combination with anorganic bovine bone-derived mineral, for horizontal ridge augmentation and subsequent implant placement.
Particulated autogenous bone, either alone or in combination with anorganic bovine bone-derived mineral, was used for lateral ridge augmentation and covered with a new synthetic resorbable membrane (glycolide and trimethylene carbonate) to treat knife-edged ridges and prepare them for implant placement. Ridge measurements were obtained before and after augmentation, complications were recorded, and biopsy specimens were examined histologically.
Fifty-eight implants were placed in 22 patients with 25 surgical sites in knife-edged ridges. No complications were associated with this treatment. Clinical measurements revealed an average of 5.56 mm (± 1.45 mm) of lateral ridge augmentation after an average of 8.12 months (± 2.32 months) of graft healing. Clinically, all treated ridges were sufficient in width for subsequent implant placement. All implants have survived, with an average follow-up period of 45.88 months (± 12.43 months). Histologic analysis of the selected augmentation sites showed new bone formation and good incorporation of the bovine bone mineral particles.
The high implant survival rate and the low complication rate show the potential of this technique for the treatment of horizontal augmentation of lateral ridges and the efficacy of the new resorbable synthetic membrane.
本前瞻性病例系列研究评估了一种新型合成可吸收膜与自体骨联合应用（单独或与牛骨衍生的无机矿物质联合应用），用于水平骨嵴增量和随后的种植体植入。
将颗粒状自体骨单独或与牛骨衍生的无机矿物质联合应用于侧向骨嵴增量，并覆盖新型合成可吸收膜（乙交酯和三亚甲基碳酸酯），以治疗刃状嵴并准备进行种植体植入。在增量前后进行了牙槽嵴测量，记录了并发症，并进行了组织学活检。
22 名患者的 25 个手术部位中有 58 个种植体植入了刃状嵴。这种治疗方法没有相关并发症。临床测量显示，平均 8.12 个月（± 2.32 个月）的移植物愈合后，侧向骨嵴平均增加了 5.56 毫米（± 1.45 毫米）。临床上，所有治疗的牙槽嵴在宽度上都足以进行后续的种植体植入。所有的种植体都存活了下来，平均随访时间为 45.88 个月（± 12.43 个月）。对选定的增量部位进行组织学分析显示，新骨形成和牛骨矿物质颗粒的良好结合。
高种植体存活率和低并发症发生率表明，该技术具有治疗侧向骨嵴水平增量的潜力，以及新型可吸收合成膜的疗效。
