摘　　要：目的:探讨下颌后牙区"三明治"法增骨同期口腔种植的临床疗效。方法:针对下颌后牙区牙槽嵴萎缩的3例患者,采用超声骨刀行"三明治"水平截骨术,同期植入2颗种植体,以支撑并稳定要提升的骨段,并于"三明治"区植入异体骨块、骨粉,促进成骨并辅以支撑骨段作用。利用GBR技术阻断结缔组织侵入。潜入式种植术后6个月行二期手术,2周后修复。结果:3例患者术后创口均无裂开,2例局部略肿胀,经抗生素和激素治疗3 d后逐渐消退。术后6个月X线片示截骨线骨性愈合,种植体周骨整合良好,牙槽嵴平均增高约5 mm。修复获得成功。结论:选择合适的患者,后牙区"三明治"法增骨同期种植是可行的。PURPOSE： To evaluate the clinical values of alveolar ridge augment of atrophic posterior mandible using modified sandwich technique with immediate implantations. METHODS： Three patients with atrophic posterior mandible were enrolled in this study. A sandwich osteotomy was performed using a piezosurgery device, and 2 submerged implants were placed in approximal locations simultaneously to support and stabilize the osteotomy segments. Some xenografts were inserted into sandwich region and a GBR membrane was applied during operations. After 6 months, definitive prostheses were completed. RESULTS： No dehiscence of the mucosa was observed in all patients. 2 patients＇ swelling gradually disappeared after a therapy with antibiotics and dexamethasone for 3 days. Six months later, newly formed bones were observed near the osteotomized segments, and peri-implant area showed osseointegration. The mean height of augmentation was about 5mm. CONCLUSION： Augmentation of alveolar ridge with immediate implantations using modified sandwich technique is applicable.
