概括

有弹性链的临时固装置 (TAD) 防止前部开口咬伤的正面切口外置. 这提高了术后的稳定性,减少了复发的可能性,改善了手术的结果.

科学领域:

牙整形和牙脸整形
牙科手术

背景情况:

术后的稳定性是前部开口咬伤手术的一个主要挑战.
预先调整的标准固定器件可能会导致牙弧平整过程中意外的切口和牙挤出.
这种挤出可能会导致复发,导致手术后正确的前部开口咬伤重新开放.

研究的目的:

介绍一种方法,以防止前部开口咬伤不良的患者在术前平整阶段的正牙治疗.
增强前部开口咬伤整形手术的术后稳定性.

主要方法:

使用两个临时固装置 (TAD) 控制膜骨的切口位置.
从门线向TAD施加被动弹性力,以抵消门平时的挤出.
进行了勒福特I骨切除术, 进行了部自旋和骨切除术.
确保手术后没有进行垂直牙移动.

主要成果:

脑力测试分析证实在手术前平整过程中没有发生前牙的挤出.
手术纠正导致了I级的切口和骨位置.
患者在手术后三个月成功解脱了可拆卸的保持器.

结论:

在前大膜骨中放置的临时固装置 (TAD),与弹性链一起,可以有效地防止意外的大切口挤出.
这种技术提高了通过直立手术实现的前部开口咬的潜在稳定性.
预防手术前挤出是实现前部开口咬伤纠正长期稳定的关键因素.

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
