PURPOSE
Orthognathic surgery is generally used to correct facial deformities and establish functional occlusion. Preoperative orthodontic treatment is important for stabilizing and establishing the postoperative occlusion. However, sufficient preoperative surgical orthodontic treatment might be sometimes difficult in patients with an abnormally shaped maxilla or mandible or severe jaw deformity.
METHODS
We performed this technique over 10 patients with jaw deformities after insufficient presurgical orthodontic treatment. Adhesive resins are attached to the maxillary palatal cusps to during surgery for disclusion of the premolars and molars.
RESULTS
The resins which are interfered during the postoperative orthodontic treatment can be removed gradually with a bur. Postoperative orthodontic treatment can be subsequently facilitated with a stable occlusion.
CONCLUSION
This technique should be applied for surgery-first orthognathic surgery and avoidance of multi-piece Le Fort I osteotomy, and can facilitate postoperative orthodontic treatment following gradually removal of cusp interferences.
目的
正颌外科手术通常用于矫正面部畸形并建立功能性咬合。术前正畸治疗对于稳定和建立术后咬合至关重要。然而，对于上颌或下颌形状异常或严重颌骨畸形的患者，有时可能难以进行充分的术前外科正畸治疗。
方法
我们对10例术前正畸治疗不足的颌骨畸形患者实施了该技术。在手术过程中，将粘结树脂附着在上颌腭尖上，以使前磨牙和磨牙脱离咬合。
结果
术后正畸治疗过程中受到干扰的树脂可用车针逐渐去除。随后可通过稳定的咬合促进术后正畸治疗。
结论
该技术应用于先行手术的正颌外科手术并避免多块Le Fort I截骨术，且随着尖干扰的逐渐消除可促进术后正畸治疗。
