摘要
方法50例下颌畸形患者接受了Le Fort I或双侧矢状劈开截骨术。患者被分为两组：第一组接受聚乳酸迷你板系统进行骨固定，第二组接受钛迷你板系统。在术前、术后 1 个月和 6 个月时进行锥形束计算机断层扫描（CBCT）。结果两组患者术后 6 个月的上颌骨稳定性无明显差异。结论使用聚左旋乳酸迷你板系统进行上颌骨固定的术后稳定性与使用钛迷你板系统的术后稳定性相当。
Comparative three-dimensional maxillary stability assessment: Bioresorbable miniplate vs. titanium miniplate systems in Le Fort I osteotomy
Objective
This study aimed to evaluate the usefulness of bioresorbable miniplates by comparing the three-dimensional maxillary stability of poly L-lactic acid and titanium miniplate systems in Le Fort I osteotomy.
Methods
Fifty patients with jaw deformities underwent Le Fort I or bilateral sagittal split osteotomies. The patients were divided into two groups: the first group received the polylactic acid miniplate system for bone fixation, while the second group received the titanium miniplate system. Cone-beam computed tomography (CBCT) was performed before surgery and at 1 and 6 months after surgery. The acquired images were overlapped to quantify the extent of maxillary relapse by calculating the difference in the distance moved between 1 and 6 months after surgery.
Results
There was no significant difference in maxillary stability between the two groups 6 months after surgery.
Conclusions
The postoperative stability achieved using the poly L-lactic acid miniplate system for maxillary fixation was comparable to that achieved using the titanium miniplate system.
