2、种植体周围骨组织和牙龈组织的状况.比较两组种植体边缘骨吸收量和周围软组织红色美学指数。利用统计学方法分析所得数据。结果不同连接方式种植修复后种植体周围边缘骨吸收量与红色美学指数具有显著差异.平台转换种植体的骨吸收量明显少于传统基台连接组。红色美学指数也高于传统基台连接结论平台转换种植体在上颌美学区单牙种植修复相较于传统基台连接种植体能更有效的保留周围骨组织且美学效果较佳。【关键词】美学区;单牙种植;平台转换;骨吸收Clinicalcomparisonofdiferentabutmentconnectiononperi·implanttissuesWuYalin,LuoZhibin,Zhua
