This study aims to investigate strategies for reducing early relapse following mandibular distraction osteotomy (MDO) in craniofacial microsomia (CFM) patients.
Forty CFM patients were divided into 2 groups: 20 underwent MDO alone, while 20 received MDO combined with orthodontic treatment (MDO-O). Preoperative, prefixation, and postfixation CT data in DICOM format were collected and reconstructed using Proplan software. Spatial geometric analysis was conducted to assess the inclination angle of the occlusal plane (OP), and OP deviation was directly measured using the software.
Patients in the MDO-O group demonstrated a statistically significant improvement in OP inclination at the end of the fixation period compared with those who underwent MDO alone ( P =0.003).
Combining MDO with a bite plate and bite glue sticks in CFM patients during the mixed dentition period enhances OP outcomes, effectively reducing short-term recurrence.
本研究旨在探讨减少颅面骨发育不全（CFM）患者下颌骨牵引成骨（MDO）术后早期复发的策略。
40 例 CFM 患者分为两组：20 例单纯接受 MDO，20 例接受 MDO 联合正畸治疗（MDO-O）。以 DICOM 格式收集术前、预牵引和固定后 CT 数据，并使用 Proplan 软件进行空间几何分析，以评估咬合平面（OP）的倾斜角，并使用软件直接测量 OP 偏斜。
MDO-O 组患者在固定期结束时的 OP 倾斜度明显优于单纯 MDO 组（P=0.003）。
在混合牙列期，将 MDO 与咬合板和咬合胶棒联合应用于 CFM 患者，可以改善 OP 结果，有效减少短期复发。
