CBCT在下颌第三磨牙阻生拔除术中的应用

The Application of CBCT in the Extraction of the Third Impacted Mandible Molar

目的:对比分析我科在CBCT介导下涡轮机钻法与常规X线介导下涡轮机钻法下颌第三磨牙阻生拔除术中及术后出现并发症的情况,分析其可能原因及预防方法,并了解患者对手术主观满意度.方法:分析在CBCT介导下和常规X线片或曲面断层片介导涡轮机钻法拔除下颌第三磨牙阻生54例,出现术中或术后并发症的12例.术后患者对手术前、后主观满意度评价.结果:采用CBCT介导下涡轮机钻法拔除的26例病例中,出现术中或术后并发症的有3例,占11.5%;而采用常规X线片或曲面断层片介导下涡轮机钻法拔除的28例病例中,出现术前或术后并发症的有9例,占32%.CBCT介导组患者对手术主观满意度高于常规组.结论:CBCT介导下涡轮机钻法拔除阻生下颌第三磨牙可减少拔牙手术并发症的发生,提高患者的满意度.

Objectives ：This paper compares and analyzes the extraction of third impacted molar under the CBCT and mediated turbine drill in our department and relevant complications by the way of conven -tional X - ray .What’s more ,it also analyzes the likeliest causes and put forward some preventive meth-ods ,meanwhile it helps us to understand the subjective satisfaction of patients after operation .Methods ：This paper has analyzed 54 cases of the extraction of the third impacted mandible molars under the CBCT , conventional X - ray ,panoramic radiographs and mediated turbine drill . There are 12 cases of surgery complications during and after operation .At last ,it evaluates the subjective satisfaction of patients before and after the operation .Results ：These 26 extraction cases with CBCT mediated by turbine drill ,among which there are 3 cases with surgery complications during and after the operation .It accounts for 11 .5% ;while other 28 extraction cases under the conventional X - ray or panoramic radiographs of turbine drill , there are 9 cases of surgery complications before or after the operation ,which accounts for 32% .The pa-tients’ percentage of subjective satisfaction with CBCT mediated operation was much higher than that of conventional ones .Conclusion ：The applications of CBCT mediated turbine drill in extraction of the impact -ed third mandible molar can decrease the relevant surgery complications .In this way ,it can make the pa-tients feel satisfactory .
