Clinical application of the sinus floor elevation using osteotome technique guided by CBCT
摘要
Abstract
Objective To Explore the accuracy of posterior maxillary bone height by CBCT and assess the clinical results after a modified osteotome technique to lift sinus floor without grafting materials. Methods 55 cases with tooth lost in maxillary posterior were taken CBCT;the objects that would be taken sinus floor elevation using osteotome technique without grafting materials were decided by the analysis of bone height results,then to evaluate the clinical results after the restoration of the tooth. Results 45 cases were detected with a lacking of maxillary posterior alveolar bone height,and 1 case was diagnosed as maxillary radicular cyst,2 cases were found as sinus mucosal hyperplasia,and 4 cases whose sinus alveolar bone height were less than 4mm recommended the using of maxillary sinus wall of windows surgery, 38 patients completed the sinus floor elevation using Osteotome Technique and finished the restorations at last.The success rate was 100％ within one year. Conclusion CBCT has an important role in determining the quality of the bone in maxillary posterior and in preoperative guidance before the implant operation.关键词
