摘　　要：目的:研究天然牙-种植体联合支持式套筒冠义齿的临床疗效。方法:用常规种植方法为20例下颌第一二磨牙缺失的患者植入种植体于第二磨牙区,下颌第二前磨牙行常规牙体预备,采用天然牙-种植体支持的套筒冠义齿修复。采用自觉症状、种植体-天然牙的临床动度、X线片、菌斑指数、牙龈出血指数和牙周袋探诊深度、种植体周围牙槽骨高度的X线片变化作为观察指标,进行为期5年的临床观察。结果:20例患者在临床观察期间,行驶功能良好,所有种植体均无松动及种植体周围X线未见异常透射影,天然牙松动度在正常范围内。种植体周围骨骨吸收量为(0.22±0.10)mm,其近远中邻面骨降低值无明显差异(P>0.05)。种植体-天然牙套筒冠修复体表面多数位点有不同程度菌斑堆积,黏膜有炎症位点占所有检测位点的31.5%;种植体所有检测位点的探针深度均值为(2.5±0.9)mm,天然牙的检测位点的探针深度均值为(2.3±0.7)mm。结论:天然牙与种植体联合支持式套筒冠义齿修复5年内的临床疗效满意,是临床上可采用的修复方式。Objective:To study the clinical efficacy of natural tooth-implant combined support telescopic dentures.Methods:Twenty patients with missing mandibular first molars were implanted with implants in the second molar area by conventional implantation methods.The second premolars of mandibular teeth were prepared by conventional dental implants with sleeve-shaped dentures supported by natural teeth and implant repair.Using observation symptoms,clinical dynamics of implant-natural teeth,X-ray films,plaque index,gingival bleeding index,periodontal pocket exploration depth,and X-ray film changes of alveolar bone height around the implant as observation indicators with a 5-year clinical observation.Results:During the clinical observation period,20 patients had good driving performance,no loosening of all implants and no abnormal transmission of X-rays around the implants.The looseness of natural teeth was within the normal range.The amount of bone and bone resorption around the implant was(0.22±0.10)mm and there was no significant difference in the bone reduction values near and near the mesial(P>0.05).Most sites on the surface of implant-natural dental sleeve crown restorations have plaque accumulation to varying degrees,and inflammation sites on the mucosa account for 31.5%of all detection sites;the average probe depth of all detection sites of the implant is(2.5±0.9)mm,the average probe depth of the detection site of the natural tooth is(2.3±0.7)mm.Conclusion:The clinical effect of the five-year restoration of telescopic dentures supported by natural teeth and implants is satisfactory,and it is a clinically applicable restoration method.
