摘　　要：目的探讨对经牙周治疗的重度慢性牙周炎患者拔除剩余牙齿后同期植入种植体并采用全颌种植义齿修复的可行性。方法对12例重度慢性牙周炎患者行牙周治疗,控制病情后,拔除剩余牙齿并同期植入种植体,5～6个月后行全颌种植义齿修复。根据临床、X 线检查和患者主诉评价修复效果。结果共计108枚种植体植入20个牙弓,其中37枚种植体即刻植入拔牙窝内。种植体平均承载3年,所有种植体均无松动。2枚种植体发生种植体周围炎,有进行性骨吸收,其中1枚为即刻植入拔牙窝内的种植体。除2枚有进行性骨吸收的种植体外,其余种植体周围的骨吸收高度平均为(1.33±0.10)mm。108枚种植体的存留率为98.1%,37枚即刻种植体的存留率为97.3%。结论对重度慢性牙周炎患者行牙周治疗后拔除剩余牙齿并同期植入种植体,采用全颌种植义齿修复,可减少牙槽骨的吸收、缩短种植修复疗程,在定期的口腔卫生维护下获得理想的修复效果。Objective To evaluate clinical results of implant-supported complete denture of 12 patients with severe chronic periodontitis. Methods After systematically periodontic treatment and controlling the inflammation, 12 cases with severe chronic periodontitis were extracted the residual teeth and received immediate implant placement. The implant-supported complete dentures were finished at 5 or 6 months after operation. Restorative results were evaluated with clinical examination, radiological examination and chief complaints of the patients. Results A total of 108 implants were placed into 20 dental arches, including 37 immediate implants. Average loading was for 3 years and all implants were stable. Progressive bone resorption was observed around two implants. The average bone resorption of other peri-implants was （1.33 ± 0. 10） mm. The implant survival rate was 98. 1%. The immediate implant survival rate was 97.3%. Conclusions After periedontic treatment, the patients with severe chronic periedontitis could be restored using immediate implant placement and implant-supported complete denture. It can shorten the treatment period, reduce absorption of alveolar and obtain a favorable result by oral health care.
