背景
几十年来的纵向临床结果有助于了解导致种植失败或并发症的潜在因素,并在治疗方法的选择方面提供帮助。


方法
对1984 - 1990年间在七个私人诊所接受钛等离子体喷涂表面种植体治疗并修复的所有病例进行了回顾性分析。用Kaplan-Meier生存曲线计算累积存活率,种植体周围炎累积发生率和无并发症修复率,并且对影响种植体存活率和种植体周围炎发生率的因素作为单一变量进行单因素分析和多因素分析。

结果
大约92例患共有223例植入物和106例修复体。62%的种植体和患者在治疗后25年内脱落。10年,15年和25年种植体累积生存率分别为97.4%,95.4%和89.8%。在种植位点观察到显著差异。10年,15年和25年种植体周围炎累积发生率分别为15.3%,21.0%和27.9%。在性别,种植体类型和种植体周围角化黏膜的宽度方面观察到显著差异。无并发症修复体在10年,15年和25年的累积生存率分别为74.9%,68.8%和56.4%。修复体类型的差别导致显著差异。

结论
随访期间高脱落率表明确定长期(> 25年)预后较困难。性别、位置和角化粘膜宽度影响种植体周围炎的发展,导致晚期失败。种植覆盖义齿经常修理。牙-种植体支持修复体不利于长期存活。
