to evaluate the efficacy of dual-purpose computer-generated splint in guiding the proximal and the distal segment in bilateral sagittal split osteotomy.
It was a prospective case series study directed on 8 class III patients indicating the need of maxillary advancement and mandibular set back by bilateral sagittal split osteotomy. A CAD/CAM splint is generated to guide the distal segment to the stable maxilla and at the same time a grooved extension to engage the proximal segment ensuring the condyle in its planned position during fixation. The primary outcome was measured by calculating the difference between the pre- and post-operative condylar segment position.
The present study included five female patient and three male patient with mean age of 28.4 ± 5.1 years. The accuracy of the splint in positioning the mandibular proximal segment showed promising results ranging from 2.59 to 0.49.
The dual-purpose splint introduced in this study showed satisfied results in maintaining the pre-operative condylar position while securing the distal segment in the desired plan.
评估两用计算机生成夹板在双侧矢状劈开截骨术中引导近段和远段的效果。
这是一项前瞻性病例系列研究，针对8例III类患者，这些患者需要通过双侧矢状劈开截骨术进行上颌前徙和下颌后退。生成一个计算机辅助设计/计算机辅助制造（CAD/CAM）夹板，以引导远段至稳定的上颌骨，同时生成一个带槽延伸部分以接合近段，确保髁突在固定过程中处于计划位置。主要结果通过计算术前和术后髁突段位置的差异来衡量。
本研究包括5名女性患者和3名男性患者，平均年龄为28.4±5.1岁。夹板在下颌近段定位方面的准确性显示出良好的结果，范围为2.59至0.49。
本研究中引入的两用夹板在维持术前髁突位置的同时，将远段固定在理想位置方面显示出令人满意的结果。
