牙植入物宏观结构没有影响全门下假肢即时加载的临床性能或生存率. 穿孔三角线 (CT) 的圆柱体和结合线 (TST) 的圆柱体缩植入物都表现出可预测的结果.
科学领域:
- 牙科植入物学 牙科植入物学
- 生物材料科学 生物材料科学
- 牙修复 牙修复 牙修复 牙修复 牙修复
背景情况:
- 具有水友表面的牙植入物对于骨质整合至关重要.
- 植入物宏观结构设计影响主要稳定性和长期临床结果.
- 评估不同的宏观结构对于优化即时加载协议至关重要.
研究的目的:
- 为了比较两个水友牙科植入物宏观结构的临床性能:带有穿孔三角线 (CT) 的圆柱体和带有组合线 (TST) 的圆柱体.
- 评估存活率,初级和二级稳定性,边缘骨水平变化,以及植入周边临床参数.
- 确定两种类型的植入物适合于立即加载全门下假肢的适用性.
主要方法:
- 一个多中心,分口,单盲,随机对照试验.
- 30名患者在无牙下中接受了CT和TST植入物.
- 通过插入扭矩和共振频率分析 (RFA) 测量初级稳定性;在24个月内评估临床参数和RFA;通过X射线评估边缘骨水平变化.
主要成果:
- 28名患者完成了为期2年的随访.
- CT的生存率为99.16%,TST植入器的生存率为100%.
- 在边缘骨水平变化或其他临床参数方面,CT和TST植入物之间没有发现显著差异.
结论:
- 植入物宏观结构 (CT与TST) 没有影响生存率,稳定性,边缘骨损失或植入周围健康.
- 这两种植入物设计都适合立即加载全门下假肢.
- 这些发现支持这些水友植入物的可预测性使用,无论评估的宏观结构如何.
