【全颌种植义齿修复慢性中重度牙周炎的临床疗效】 淮安全颌种植义齿价钱
[摘要] 目的 探讨全颌种植义齿修复慢性中重度牙周炎的临床疗效。 方法 回顾性分析24例慢性中重度牙周炎患者的临床资料，该组患者经牙周治疗病情控制后采用全颌种植义齿修复，根据患者主诉、临床及X线评价修复效果。 结果 共216枚种植体植入20个牙弓，其中有2枚即刻种植于术后3周脱落，即可种植体的保留率为97.3%，种植体平均保留率为97.7%。种植体平均承载42个月，所有种植体均无松动。骨吸收高度平均为（1.73±0.13）mm。 结论 采用全颌种植义齿修复慢性中重度牙周炎可减少牙槽骨的吸收，缩短种植修复疗程，但同时要坚持定期的口腔护理。

[Abstract] Objective To investigate the clinical effect of implant-supported complete denture of patients with moderate to severe chronic periodontitis. Methods To analyze retrospectively of clinical data of 24 patients with moderate to severe chronic periodontitis, the group of patients were given the treatment of edentulous implant denture after disease control the, to evaluate the repairing effect according to patients" complaints, clinical and radiographic evaluation. Results There were 216 cases of implants were implanted in 20 dental arch, 2 of them were immediate implant in postoperative 3 weeks off, then the implant retention rate was 97.3%, the average retention rate was 97.7%. Implant 46 months average loading, all implants were not loose. The average height for bone resorption was (1.73±0.13) mm. Conclusion The implant-supported complete denture to chronic moderate to severe periodontitis can reduce the absorption of alveolar bone, shorten implant treatment, but at the same time should adhere to regular oral care.

对牙周炎患者行种植修复，临床上尚存在许多争议。部分学者认为牙周炎的致病菌易导致种植体周围炎，会降低种植的成功率。但近来有研究显示，慢性牙周炎患者病情稳定后可以行种植修复，短期疗效较牙周健康者没有差异[1]。山东省青岛市口腔医院2007年8月～2011年1月采用全颌种植义齿修复慢性中重度牙周炎患者24例，疗效满意。现报道如下：
1 资料与方法
1.1 一般资料
24例中重度慢性牙周炎患者，所有病例均符合《牙周病学》的诊断标准，经牙龈指数（GI）、牙周探诊（PD）及X线检查确诊，均有不同程度的牙列缺损，无胃肠道、心、肝、肾等主要脏器严重疾病，排除系统性疾病、孕期及哺乳期者。患者全身状况良好，无种植修复的全身禁忌证。其中男12例，女12例，年龄25～70岁，平均（52.4±4.5）岁，口腔卫生较差，牙龈充血红肿，牙石较重，探诊易出血，牙周袋探诊深度4～9 mm，附着丧失7～10 mm，有不同程度的牙齿松动，松动度≤Ⅱ°，X线显示牙槽骨水平型或角型吸收超过根长1/3，根据患者缺失牙的部位和剩余牙齿状况，患者剩余牙齿均无法保留，需采用全颌种植义齿修复。
