摘要/Abstract

摘要： ［摘要］目的测量青少年与成年患者腭骨皮质骨密度，为临床微螺钉种植体的应用提供参考。方法选择30例青少年患者(平均年龄（13.2±1.2）岁),30例成人患者(平均年龄(23.2±4.9)岁)，其中男女各半，分别拍摄CBCT。对所有患者的腭骨进行皮质骨密度测试，腭骨被分为72个测试区域。结果成年人组的骨密度(（736±5）hu)大于青少年组(（613±28）hu)；（P ＜0.01）。男性患者的骨密度大于同组的女性患者骨密度。所有患者的腭骨侧面骨密度都明显小于中间骨密度（P ＜0.01）。结论成人组的腭骨骨密度高于青少年组，女性的腭骨骨密度低于男性。

Abstract: Abstract: Objective To measure palatine cortical bone densities of adolescent and adult patients to provide,and the reference for the clinical application of micro screw implant.Methods 30 cases of adolescent patients (mean age (13.2 ± 1.2) years),and 30 cases of adult patients (mean age (23.2 ± 4.9) years) were selected,among whom there were half men and half women.CBCT was taken respectively.Cortical bone density testing was performed on all patients and palatal bones were divided into 72 test areas.Results The density of the adults group ((736 ± 5)hu)was greater than that of the adolescents group ((613 ± 28)hu; P <0.01).Bone mineral density in male patients was greater than that in female patients in the same group.The lateral bone density in all patients was significantly less than that in the middle side of the bone (P <0.01).Conclusions The palatal bone density of adult group is significantly higher than that in adolescent group,palatal bone density in women is lower than that in men.
