Corticotomy found to be effective in accelerating orthodontic treatment. The most important factors in the success of this technique is proper case selection and careful surgical and orthodontic treatment. Corticotomy facilitated orthodontics advocated for comprehensive fixed orthodontic appliances in conjunction with full thickness flaps and labial and lingual corticotomies around teeth to be moved. Bone graft should be applied directly over the bone cuts and the flap sutured in place. Tooth movement should be initiated two weeks after the surgery, and every two weeks thereafter by activation of the orthodontic appliance. Orthodontic treatment time with this technique will be reduced to one-third the time of conventional orthodontics. Alveolar augmentation of labial and lingual cortical plates were used in an effort to enhance and strengthen the periodontium, reasoning that the addition of bone to alveolar housing of the teeth, using modern bone grafting techniques, ensures root coverage as the dental arch expanded. Corticotomy facilitated orthodontics is promising procedure but only few cases were reported in the literature. Controlled clinical and histological studies are needed to understand the biology of tooth movement with this procedure, the effect on teeth and bone, post-retention stability, measuring the volume of mature bone formation, and determining the status of the periodontium and roots after treatment.
皮质切开术被发现对加速正畸治疗有效。该技术成功的最重要因素是正确的病例选择以及仔细的外科手术和正畸治疗。皮质切开辅助正畸法主张使用全口固定正畸矫治器,并在待移动牙齿周围进行全厚瓣切开以及唇侧和舌侧皮质切开。骨移植材料应直接覆盖在骨切口上,然后将瓣缝合到位。术后两周开始牙齿移动,此后每两周通过激活正畸矫治器进行一次。采用该技术的正畸治疗时间将缩短至传统正畸治疗时间的三分之一。使用唇侧和舌侧皮质板的牙槽嵴增高术来增强和加固牙周组织,理由是采用现代骨移植技术向牙齿的牙槽窝添加骨组织可确保在牙弓扩展时牙根得到覆盖。皮质切开辅助正畸法是一种有前景的方法,但文献中报道的病例很少。需要进行对照的临床和组织学研究,以了解该方法中牙齿移动的生物学原理、对牙齿和骨骼的影响、保持后的稳定性、测量成熟骨形成的体积以及确定治疗后牙周组织和牙根的状况。
