摘要
目的:观察口腔颌面部严重创伤后牙缺失伴骨缺损的种植修复临床效果。方法:颌面部严重创伤后牙缺失伴骨缺损患者20例,其中多颗牙连续缺失者12例,共植入ITI Straumann等常用牙种植体65枚,其中5例行骨劈开+骨挤压+骨引导再生(guided bone regeneration,GBR)技术。2~6个月后行上部结构修复,定期随访,检查种植体骨结合情况、种植体周围软组织与修复体情况。结果:本组病例修复后经1~5年的临床观察,除1例所植入的5枚种植体中的1枚,在修复后3年脱落,其余患者各项评价指标均良好,种植体存留率为98%。结论:颌面部严重创伤后的牙列缺损,尤其多颗牙的连续缺失,很难采用其他固定修复方法来完成。种植修复具有不损伤余留牙、美观舒适、咀嚼效果好等优点,是一种良好的修复方法。
Objective: To summarize the clinical effects of dental implants in the restoration of dentition defect patients caused by serious trauma. Methods: 20 patients were retrospectively reviewed. 12 cases had multiple teeth extraction. 65 ITI Straumann dental implants were implanted. 5 cases were performed by alveolar ridge splitting + osteocondensation + guided bone regeneration (GBR) procedure. After 2-6 months, the upper part of the defect was restored. Oral health, implant osseointegration and soft tissue quality were evaluated in 1-5 years after treatments. Results: Only one patient showed prosthetic complication as one implant loss 3 years after implantation. The success rate was 98%. Patients were satisfied with these treatments. Conclusion: The dental implant technique is a good method to repair dentition defect caused by serious trauma.
