Bone distraction is the process of new bone formation between the surfaces of bone segments gradually separated by incremental traction of soft tissues. These adaptive changes in the soft tissues allow for greater skeletal movements while minimizing the potential relapse. In this study, we are reporting our clinical experience with mandibular distraction used to achieve simultaneous skeletal and soft-tissue correction with distraction osteogenesis (DO).
A total of five patients who reported to the department for the treatment of mandibular deficiencies were selected. Cephalometric studies were done preoperatively and postoperatively for hard tissue assessment. Predefined reference points were used for the clinical evaluation for the evaluation of soft tissues. Results were compared between preoperative and 1-, 3-, 6-, and 12-month postoperatively.
The clinical observations in our study showed that there is a remarkable improvement in the facial esthetics. Cephalometric analysis has shown lengthening of the mandibular corpus and increase in the height of the vertical ramus. Certain minimal complications have also been noted.
Despite the few complications, DO has become a popular surgical modality due to its many advantages.
骨牵引成骨是通过软组织的渐进性牵引使骨段表面之间形成新骨的过程。软组织的这些适应性变化可实现更大的骨骼移动，同时将潜在的复发风险降至最低。在本研究中，我们报告了使用下颌骨牵引成骨术（DO）实现骨骼和软组织同步矫正的临床经验。
共选择了5名到该科室治疗下颌骨缺陷的患者。术前和术后进行头影测量研究以评估硬组织。使用预定义的参考点进行软组织的临床评估。比较术前与术后1个月、3个月、6个月和12个月的结果。
我们研究中的临床观察表明，面部美学有显著改善。头影测量分析显示下颌体延长，垂直升支高度增加。也注意到了一些轻微并发症。
尽管有一些并发症，但由于其诸多优点，DO已成为一种流行的手术方式。
