应用锥形束CT评价前牙唇舌侧牙槽骨高度及厚度的研究
Evaluation of quantitative measurement of labial and lingual alveolar height and thickness in anterior teeth by cone-beam computed tomography
摘要
Abstract
Objective To evaluate the accuracy of in vitro and in vivo measurement of labial and lingual alveolar height and thickness in anterior teeth by cone-beam computed tomography ( CBCT). Methods Anterior teeth sockets in 10 dry mandibles were examined by CBCT, and the alveolar height and thickness were measured and compared with direct measurement. Twenty-two anterior teeth, that had been determined to extract, were examined by CBCT, and the alveolar height and thickness were measured and compared with direct measurement after the extraction. Results In vitro experiments , no significant difference was found between the data obtained by CBCT and direct measurements ( P > 0.05 ) . In vivo experiments, no significant difference was found between the data obtained by CBCT and direct measurements except for the labial alveolar height. The difference might be caused by the trauma from the extraction and patient mobility during the projection. Conclusion CBCT could provide accurate information of labial and lingual alveolar height and thickness in anterior teeth.关键词
