The aim of this study was to investigate the accuracy of a previously described technique for guided biopsy of osseous pathologies of the jawbone in a clinical setting. The data sets of patients who had undergone guided biopsy procedures were retrospectively examined for accuracy. Digital planning of the biopsies and manufacturing of the tooth-supported drilling template were performed with superimposed cone beam computed tomography and intraoral scans using implant planning software. After a trephine biopsy was taken using the template, the postoperative low-dose cone beam computed tomography was analyzed for accuracy using the planning software with the corresponding (digitally-planned) biopsy cylinder. The mean angular deviation was 4.35 ± 2.5°. The mean depth deviation was -1.40 ± 1.41 mm. Guided biopsy seems to be an alternative to a conventional approach for minimally invasive and highly accurate jawbone biopsy.
本研究旨在探讨先前描述的一种用于颌骨骨性病损引导活检的技术在临床环境中的准确性。回顾性检查了接受引导活检的患者的数据，以评估准确性。使用叠加锥形束 CT 和种植体规划软件进行的口腔内扫描对活检进行了数字化规划和牙支持的钻孔模板的制造。使用模板进行环钻活检后，使用相应的（数字化规划的）活检管，使用规划软件对术后低剂量锥形束 CT 进行了准确性分析。平均角度偏差为 4.35 ± 2.5°。平均深度偏差为-1.40 ± 1.41 mm。引导活检似乎是一种替代传统方法的选择，适用于微创和高度精确的颌骨活检。
