摘要
目的:利用锥体束计算机断层扫描(cone-beam computed tomography,CBCT)图像评估上颌前牙牙弓形态、中切牙牙根矢状位置(sagittal root position,SRP)与牙槽骨厚度的关系,并根据年龄、性别对其分组,临床医生在即刻种植体植入时应考虑这些因素.方法:对符合纳入标准的160例患者的CBCT影像进行分析,根据牙弓形态、年龄、性别对其分组,对患者的320张上颌中切牙矢状位CBCT图像进行了检查,以测量唇侧骨板和腭侧骨板厚度,进行统计学分析.结果:牙槽骨厚度因牙弓形态和SRP的不同而有显著差异.方圆形牙弓型和Ⅰ类SRP在腭侧的骨厚度最高.尖圆形弓型和Ⅱ类SRP在唇侧骨厚度最高.牙弓形态与SRP之间无显著相关性.年龄、性别、牙弓形态、SRP与牙槽骨的根尖水平厚度有显著相关性.结论:患者的年龄、性别、牙弓形态和SRP与上颌中切牙的牙槽骨厚度有不同程度的相关性.因此,临床医生在计划即刻种植体植入时应考虑这些因素.
Abstract
Objective:To evaluate the relationship between arch morphology,sagittal root position(SRP),and alveolar bone thickness of maxillary anterior teeth through cone-beam computed tomography(CBCT)images,and to group them according to age and gender.Methods:The CBCT images of 160 patients who met the inclusion crite-ria in H enan Province were analyzed and grouped according to dental arch morphology,age,and gender.Three hundred and twenty sagittal CBCT images of the maxillary central incisor of these patients were examined to meas-ure the thickness of labial and palatal plates for statistical analysis.Results:The alveolar bone thickness was signifi-cantly depended on arch morphology and SRP.The bone thickness in the palatine side was the highest in the circular dental arch and grade Ⅰ SRP.Apical arch type and grade Ⅱ SRP type had the highest labial bone thickness.There was no correlation between dental arch morphology and SRP.Age,gender,arch shape,and SRP were significantly correlated with alveolar bone thickness.Conclusion:Age,gender,arch shape,and SRP were correlated with alveo-lar bone thickness of maxillary central incisor.Clinicians should consider these factors when planning implantation.
