摘要
对４２名患者种植国产ＣＤＩＣ牙种植体６２枚，根据临床结果，评价影响种植体种植后成败的相关因素．种植体为国产ＣＤＩＣ系列，种牙机为瑞士产ＣＨ－９４００型牙种植机；部份病例在模板诱导下定位，部分于唇侧补偿填入可降解的α－磷酸三钙．术后暂冠修复或不修复，术后３～６月行上部结构永久修复．术后１月～２ａ复诊，因松动拔除５枚，失败率为８％．其中叶状体为３％，二段式种植体为８３％，锥状种植体为３３％；牙槽骨异常而未植骨者为５０％，植骨者无失败病例；术中模板诱导者为４５％，无模板诱导者为１０％．因此，受植骨床足够的数量及较好的质量是种植成功的关键；在薄弱的唇侧植入可降解的α－磷酸三钙，利于种植体的骨结合固位；术中模板诱导定位可使种植体在颌骨中的位置更适应咬关系要求；暂冠早接触是造成失败的首要因素．
Sixty - two CDIC dental implants were implanted in 42 cases since October,1995.In some case, - tricalcium phosphate ceramic was injected into the defect side of alveolar bone.The temporary prosthesis were made in 0～2 weeks.The perpetul prosthesis were made in 3～6 months.After two years' observation,5 implants had to be pulled out due to loosening.Failure rate is 8 %.Among the failure cases,the failure rate of blade implants is 3 % ; one - stage cone shape implant is 32 % ; two - stage columnar spiral implant is 8.3 % ; the failure rate of unusual alveolar is 25 % ; the unusual alveoalr bone with or without artificial bone is 50% ; the failure rates with or without guiding model implement are 4.5 % and 10 % respectively.We believed that enough quantity and quality of bone,guiding model implement used in the design of operation and avoid prematurity of temporary prosthesis are key factors for successful implantment.
