摘要
目的研究分析CBCT测量颏孔区的解剖结构。方法：回顾性分析我院收治的单侧颏孔区缺牙口腔患者病历资料。设为观察组，选择同一时期单侧颏孔区有牙口腔患者作为对照组。测量观察患者的颏孔解剖结构的大小形态及位置，结合参数的评价，做好解剖结构效果的分析。结果：（1）CBCT图像清晰率和检出率均为100％，口腔曲面断层片清晰率仅为60％，检出率仅为88％，CBCT图像测量较优，P〈0．05，表示有统计学意义；（2）左右侧正颏孔出现均为100％，左侧副颏孔出现概率10％，右侧副颏孔出现概率23．3％。（3）对照组有牙区和观察组无牙区的管嵴距、孔嵴距、管舌距、颏管的长度的变化进行比较，存在显著差异（P〈0．05）。结论：CBCT测量颏孔区的清晰度和检出率较高，同时颏孔区种植体尖端和颏孔之间的距离需要进行全面的评估，并做好常规影像学的检查。
Objective To study the anatomical structure of CBCT measurement of mental foramen. Methods： A retrospectiveanalysis of our hospital mental foramen unilateral edentulous patients with oral medical records, observation group, choose thesame period of unilateral mental foramen mouth with teeth in patients as a control group. Measuring the size and shape andposition of observation mental foramen anatomy of the patient, combined with evaluation parameters, good analysis ofanatomical structure effect. Results： （1） CBCT image clarity rate and the detection rate was 100%, oral panoramic radiographsclear rate of 60%, the detection rate was 88%, CBCT image measurement optimum, P 〈0.05, showing statistically significant;（2） left and right sides appear positive mental foramen were 100% probability of occurrence of the left deputy mental foramen10%, on the right mental foramen deputy occurrence probability of 23.3%. （3） in the control group and observation group den-tal area toothless ridge area of pipe from the hole from the ridge, away from the tube tongue, chin tubes of varying lengthswere compared, there was a significant difference （P 〈0.05）.Conclusion： CBCT foramen area of clarity and a higher detectionrate, also the foramen area planting distance between body tip and mental foramen the need for a comprehensive assessmentof, and do a good job of conventional imaging examination.
