摘要
目的锥体束CT(Cone beam computer tomography,CBCT)结合Simplant软件,术前定量判断牙种植区骨密度。方法对141例牙缺失患者进行CBCT扫描,共187个牙缺失位点,数据导入Simplant软件,对种植位点骨密度进行测量,骨密度以Hounsfield units(HU)表示,结合Lekholm和Zarb分类法进行分类统计。结果牙缺失位点骨密度平均值为(530.35±211.65)HU,下颌前牙区(783.94±109.54)HU>上颌前牙区(584.53±185.76)HU>下颌后牙区(570.88±173.07)HU>上颌后牙区(385.49±186.10)HU。上颌前牙区与下颌后牙区之间骨密度差异无统计学意义(P>0.05),男女性别差异无统计学意义(P>0.05)。结论CBCT可以反映患者术前颌骨质量信息,结合Simplant软件,对种植术前评估与规划有指导意义。
Objective By use of cone beam computer tomography(CBCT)combined with Simplant software,to assess bone density in oral implant areas before surgery.Methods 141 patients with missing teeth were scanned by CBCT.A total of 187 missing teeth were included in the data.The data were imported into the simplant software and the bone density at the implant site was measured.The bone density was expressed in Hounsfield units(HU),combined with the Lekholm and Zarb classification.Results The average bone mineral density was(530.35±211.65)HU,the anterior mandibular area(783.94±109.54)HU>was the maxillary anterior area(584.53±185.76)HU>the mandibular posterior area(570.88±173.07)HU>maxillary posterior area(385.49±186.10)HU.There was no significant difference in bone mineral density between the maxillary anterior region and the mandibular posterior region(P>0.05).There was no statistical difference between male and female genders(P>0.05).Conclusion CBCT data can reflect jaw mass information.Combined with simplant software,it has guiding significance for preoperative evaluation.
