开(牙合)是牙颌系统最严重的畸形之一,通常应用正畸方法治疗相当困难。为此作者提出了本法。材料和方法:研究对象是20名患者,年龄14～30岁,15名男性,5名女性。进行了临床和实验室检查、远距X线照相、副鼻窦X线照相、取上下颌印模、拍颜面及咬合照片、作牙电测量法、血流图。在设计手术时要参考临床及远距X线照相,在模型上预测手术效果。手术方法:从上颌两侧口腔前庭部位(图1),于单尖牙和第一双尖牙之间,由移行皱襞向下作垂直切口,距龈缘5 mm处
Open (occlusal) is one of the most serious deformities of the dental system, orthodontic treatment is usually very difficult. To this end the author proposed this law. MATERIALS AND METHODS: The study population consisted of 20 patients aged 14-30 years, 15 males and 5 females. Conducted clinical and laboratory tests, distance X-ray photography, paranasal sinus radiography, taking the lower jaw impression, pat the face and occlusion photos for dental examination, blood flow map. In the design of surgery to refer to clinical and long-range radiography, the model predicts the effect of surgery. Surgical methods: from the maxillary on both sides of the oral vestibular site (Figure 1), between the canine and the first bicuspid toe by the migration folds down for vertical incision, 5 mm from the gingival margin
