Corticotomy in fixed orthodontic treatment gives a potential approach to reduce the treatment duration. Typically, this duration of rapid tooth movement lasts 4-6 months.
The aim of this study was to compare the treatment outcome and effectiveness in en masse retraction with and without corticotomy.
Thirty-two patients (male 16 and female 16) who opted to undergo surgery to reduce the orthodontic treatment time were chosen for the research, and the group consisted of 26 patients (male 13 and female 13) who did not opt for the corticotomy procedure were selected as the control. There was no blindness of the party distribution. It was focused on the patient's ability to opt for an additional minor surgical procedure that may affect orthodontic treatment length. The operation was conducted under local anesthesia (Lignox 2%). The same maxillofacial surgeon performed all the surgical operations.
The space present in the maxillary and mandibular arch at the time of retraction had no statistically significant difference in both the control and study groups ( > 0.05). In comparison, the mean amount of retraction space in the maxillary arch and maxillary arch was significant in the control and study groups at 1 month, 2 months, 3 months, and 4 months of the time interval.
It can be concluded that corticotomy-assisted retraction significantly decreases the total length of orthodontic care. Effectively stationary anchorage segment was made, thereby removing the need for other anchorage boosters, instrumental in maximum anchorage cases using corticotomy technique.
在固定正畸治疗中进行皮质切开术为缩短治疗时间提供了一种潜在方法。通常，这种快速牙齿移动的持续时间为4至6个月。
本研究的目的是比较有或没有皮质切开术的整体内收治疗效果。
选择32例选择接受手术以缩短正畸治疗时间的患者（男16例，女16例）进行研究，并选取26例未选择皮质切开术的患者（男13例，女13例）作为对照组。分组不存在盲法。研究重点在于患者选择可能影响正畸治疗时长的额外小型外科手术的能力。手术在局部麻醉（2%利多卡因）下进行。所有手术均由同一位颌面外科医生完成。
在对照组和研究组中，内收时上颌和下颌牙弓的间隙在统计学上无显著差异（P>0.05）。相比之下，在时间间隔的第1个月、第2个月、第3个月和第4个月时，对照组和研究组上颌牙弓和上颌牙弓的平均内收间隙量具有显著性差异。
可以得出结论，皮质切开术辅助内收显著缩短了正畸治疗的总时长。有效地形成了稳定的支抗段，从而无需其他支抗增强装置，这在使用皮质切开术技术的最大支抗病例中发挥了作用。
