联合应用CAS-KIT工具盒和Summers骨凿的上颌窦内提升术的应用评价

Clinical evaluation of maxillary sinus lifting bone graft using CAS-KIT and Summers osteotome

目的：研究联合应用CAS-KIT工具盒和Summers骨凿的上颌窦内提升术同期植入种植体的临床效果。方法：对20例30颗垂直骨量不足的上颌后牙联合应用CAS-KIT工具盒和Summers骨凿的上颌窦内提升术同期牙种植，种植体上部结构修复完成后6～36个月定期复查。结果：观察期内，30枚种植体与周围组织均形成良好的骨性结合，能行使较好的咀嚼功能。结论： CAS-KIT工具盒和Summers骨凿的联合应用充分发挥了各自的优点，扩大了上颌窦内提升术的适应症；避开了CAS-KIT工具盒液压升降装置的使用不便和Summers骨凿在敲击中产生的不适感，是一种更为安全可靠的方法。

Objective： To study the effect of maxillary sinus floor lifting using CAS-KIT and Summers os-teotome by bone graft with instant implants placement. Method： 20 maxillary sinus underwent bone graft using CAS-KIT and Summers osteotome and instant 30 implants placement. The follow-up time was 6 to 36 months. Results： X ray examination showed good osteointegration without maxillary sinusi-tis. 30 implants had good function. Conclusion： Maxillary sinus floor lifting using CAS-KIT and Sum-mers osteotome by bone graft for instant implantation is satisfactory and safe to clinical application .
