The purpose of this manuscript was to assess mandibular ramus block grafts used for augmentation of mandibular posterior segments, followed by subsequent implant placement. Twenty-four human subjects in need of lateral ridge mandibular augmentation were included in the current patient series.
recipient site had at least 10-mm residual height, but less than 4.3-mm bucco-lingual dimension. Autogenous bone blocks were harvested from the mandibular ramus. In the first group ramus block was used in association with platelet-rich fibrin and in the second in association with pericardium membrane. Implant surgery was performed 4 months after bone graft surgery when a total number of 44 implants were placed. Abutments were placed 4 months after implant surgery followed by final restoration. Ramus bone graft was successful in 100% patients for the first group and in 91.67% patients for the second group. Measurement on cone beam computed tomography revealed an average of 5.35 mm of lateral ridge augmentation for group 1 and 5.099 mm for group 2, achieved 4 months after surgery. All implants placed received fixed prosthetic restorations and are in use. Ramus block grafts can be used to allow optimal implant placement, with favor long-term success. Lateral ridge augmentation using mandibular ramus bone graft in association with platelet-rich fibrin is a more predictable and successful technique.
本手稿的目的是评估用于下颌后段增宽的下颌支骨块移植，随后进行种植体植入。本患者系列纳入了24例需要下颌外侧牙槽嵴增高的受试者。
受植区剩余高度至少为10毫米，但颊舌径小于4.3毫米。自体骨块取自下颌支。第一组将骨块与富血小板纤维蛋白联合使用，第二组与心包膜联合使用。骨移植手术后4个月进行种植手术，共植入44颗种植体。种植手术后4个月放置基台，随后进行最终修复。第一组100%的患者下颌支骨移植成功，第二组为91.67%。锥形束计算机断层扫描测量显示，术后4个月，第一组外侧牙槽嵴平均增高5.35毫米，第二组为5.099毫米。所有植入的种植体均接受了固定修复，且仍在使用。下颌支骨块移植可用于实现最佳种植体植入，并有利于长期成功。使用下颌支骨移植联合富血小板纤维蛋白进行外侧牙槽嵴增高是一种更可预测且成功的技术。
