【摘要】 目的:评价计算机导航+自制外科导板指导下的无翻瓣术在种植牙中的应用推广价值。方法:通过对比来自内蒙古自治区医院口腔科的采用此项技术的8例患者年龄范围20-73岁,共13颗种植体术前术后的CT数据,利用Simplant专用种植软件分析测量,来评价其推广应用的价值。结果:通过比较测量的数据,部分种植体颈部向颊侧偏斜约10度,可以通过角度基台调整以适应咬合关系。结论:自制外科导板还存在不足,经过改进后,使导板上的导向环真正起到固定导向作用,不仅在无翻瓣术中应用,另外在需要植骨的翻瓣术中亦可推广。它在减少术后并发症,增进医患沟通等方面具有重要意义。更多还原

【Abstract】 Objective: The aim of this study was to evaluate the value of computer navigation +precisive surgical guide technique in implantology. Methods: eight patients ranging from 20 to 73 years old were recruited from Inner Morgolia Hospital ,thirteen implants were placed. The 2.2 diameter pilot guide drill was used to create a precise, minimally invasion initial penetration through the mucosa and into bone . The parameters evaluated were depth from mucosal margin to bone crest .implant position including depth and angulation in the bone. From the preoperation and postoperation CT images, for thirteen implants placed in eight patients ,the data was statisticed (Simplant software).Results: Data obtained from this study shows that the depth and angulation in panoramic is perfect ,but the angulation in cross sectional always deflexion about 10 degree to the buccal side ,angulation abutment can adjust the dental prosthetic restoration to a correct occlusion relationship. Conlusion: The results indicate this minimally invasion technique deserve generally adopted . To improving the design of the surgical guide, retention and depth controlling will remain were successful expect .更多还原
