中部地区居民上颌前牙矢状向牙根位置与周围牙槽骨的CBCT研究
CBCT study of sagittal root position and surrounding alveolar bone of maxillary anterior teeth in residents in Central China
摘要
Abstract
Objective:To analyze the sagittal root position of healthy maxillary anterior teeth of residents in the cen-tral area through CBCT imaging data,and to measure the thickness of the alveolar bone on the labial and palatal sides,the width and height of the alveolar bone,and apical bone height.This is to provide the basis for preoperative planning and prog-nosis judgment of immediate implantation in maxillary anterior tooth area.Methods:CBCT images of healthy maxillary anteri-or teeth from 70 residents in the central region were selected,and the sagittal root position classification of maxillary anterior teeth was qualitatively analyzed.The thickness of the alveolar bone on the labial and palatal sides was measured,alveolar bone width,alveolar bone height,apical bone height,and the correlation with sagittal root position were analyzed.Results:92.4%of maxillary anterior teeth root sagittal position was class Ⅰ,3.3%was class Ⅱ,and 4.3%was Ⅳ.The labial bone thickness at 2 mm apical to bone crest was smallest in class Ⅰ(P=0.014).The labial bone thickness at middle third of root was largest in class Ⅱ(P=0.001).The labial bone thickness at root apex was class Ⅳ<Ⅰ<Ⅱ(P<0.001).The palatal bone thickness was class Ⅳ<Ⅱ<Ⅰ(P<0.001).The alveolar ridge width was largest in class Ⅰ(P<0.01).The alveolar ridge height was class Ⅰ<Ⅱ<Ⅳ(P>0.05).The apical bone height was class Ⅰ<Ⅳ<Ⅱ(P=0.005).Conclusion:Through the evaluation of sagittal root position and the surrounding alveolar bone,including the thickness of the alveolar bone on the labial and palatal sides,the size of the alveolar bone,and the height of the apical bone,all have important guiding significance for the immediate implantation of the maxillary anterior teeth.关键词
