PURPOSE
This is a pilot study which aims to evaluate the accuracy of cone-beam computed tomography (CBCT) to assess the configuration and extent of ligature-induced peri-implantitis defects.
MATERIALS AND METHODS
Radiographic evaluation of advanced ligature-induced peri-implantitis defects (n = 9) in canine was performed using CBCT (central cross-sections) and compared with the corresponding histomorphometrical measurements of the respective site serving as a validation method. Deviations were calculated for the supracrestal (SC), and intrabony (IC) defect components, as well as defect width (DW) assessed at both vestibular (v) and oral (o) aspects.
RESULTS
Mean differences between CBCT and histological analyses were -0.53 ± 1.48 mm (SC), +0.49 ± 1.18 mm (IC), and +0.18 ± 0.54 mm (DW) at vestibular aspects, and -0.13 ± 0.44 mm (SC), -0.05 ± 0.62 mm (IC), and +0.15 ± 0.48 mm (DW) at the oral aspects (P > 0.05; paired t test, respectively).
CONCLUSION
CBCT may represent an accurate diagnostic tool to estimate the histological extent of advanced peri-implantitis defects.
目的
本研究为一项初步研究，旨在评估锥形束计算机断层扫描（CBCT）评估结扎诱导性种植体周围炎缺损的形态和范围的准确性。
材料与方法
使用CBCT（中心横截面）对犬类中晚期结扎诱导性种植体周围炎缺损（n = 9）进行影像学评估，并与作为验证方法的相应部位的组织形态计量学测量结果进行比较。计算龈上（SC）和骨内（IC）缺损成分以及在前庭（v）和口腔（o）方面评估的缺损宽度（DW）的偏差。
结果
CBCT与组织学分析之间的平均差异在前庭方面为-0.53±1.48毫米（SC）、+0.49±1.18毫米（IC）和+0.18±0.54毫米（DW），在口腔方面为-0.13±0.44毫米（SC）、-0.05±0.62毫米（IC）和+0.15±0.48毫米（DW）（P>0.05；配对t检验）。
结论
CBCT可能是一种准确的诊断工具，可用于估计晚期种植体周围炎缺损的组织学范围。
