CBCT用于分析后牙区松质骨骨体积分数的可行性研究
Feasibility Study on CBCT for the Analysis of Cancellous Bone Volume Fraction in the Posterior Region
摘要
Abstract
Objective By comparing cone-beam computed tomography(CBCT)data measured by CTAn software with the bone volume fraction of cancellous bone in the proposed implant area measured by pathological tissue sections,and to investigate the feasibility of CBCT for evaluating cancellous bone quality in the jaws.Methods Implant patients attending the First Hospital of the University of Science and Technology of China(Anhui Provincial Hospital)from June 2020 to August 2021 were selected as the study subjects for this experiment.A total of 37 patients,21 women and 16 men,with a mean age of(45.03±13.23)years,had a total of 39 complete bone blocks removed from the proposed implant area.The bone blocks removed intraoperatively were made into bone tissue sections,and the cancellous bone volume fraction of the bone blocks was measured by pathological image analysis software,and the cancellous bone volume fraction of the proposed implant area was measured by the cancellous bone measurement software CTAn to compare whether there were differences in the results measured by different methods.Results The cancellous bone volume fraction measured by pathology was(43.84±11.31)%,(45.20±10.61)%and(41.67±12.03)%in the posterior,maxillary posterior and mandibular posterior regions,respectively.The cancellous bone volume fraction measured by CTAn was(43.65±11.20)%,(45.10±10.52)%and(41.32±11.86)%,respectively,with no statistical difference between the results obtained by the two measurement methods(P＞0.05).Conclusion The cancellous bone volume fraction of the jaws can be analyzed by CBCT data to make an objective evaluation ofthe cancellous bone bone quality of the jaws.关键词
