目的观察患重度牙周炎合并龈缺损及骨开裂上颌磨牙的种植修复临床效果。方法 15例重度牙周炎合并龈缺损及骨开裂的上颌磨牙患者,均使用腭侧滑行皮片行拔牙后即刻引导骨组织再生术(GBR)软组织关闭,6个月后行牙种植术,牙种植术6个月后再行修复治疗,观察其术后软组织愈合、成骨以及种植体存留情况。结果 15例患者GBR术后创口愈合正常,成骨效果良好,植入种植体存留率100%(15/15),种植体周软硬组织健康。结论重度牙周炎合并龈缺损及骨开裂患者使用腭侧滑行皮片完成即刻GBR,可获得良好的牙槽骨条件,后续种植修复治疗临床效果良好。
Objective To observe the clinical effect of implant restoration of maxillary molars with severe periodontitis complicated with gingival defect and bone dehiscence. Methods Twenty-five patients with maxillary molars with severe periodontitis complicated with gingival defect and bone dehiscence were treated with palatal gliding skin flap guided by GBR soft tissue immediately after tooth extraction. Tooth implants were performed 6 months later. Six months after implantation, the patients were rehabilitated and the postoperative soft tissue healing, osteogenesis and implant survival were observed. Results The wound healing of GBR after operation was normal in 15 patients. The osteogenic effect was good. The implant survival rate was 100% (15/15). The hard and soft tissues of implant were healthy. Conclusions Patients with severe periodontitis complicated with gingival defect and bone dehiscence who completed the immediate GBR using the palatal gliding skin flap could obtain good alveolar bone condition, and the follow-up implanting repair had a good clinical effect.
