前牙反(牙合)在牙颌畸形中较为常见,尤其是在乳牙、恒牙交替时期及恒牙列早期发病率较高。对前牙反(牙合)较深的反(牙合),且反(牙合)牙的数目较多时,往往因为操作复杂、舒适感差、矫治时间长而不能取得满意的效果。我们通过联合应用固定、活动矫治器矫治前牙深度反(牙合),均取得了较好的疗效。 1 临床资料 收治深度反(牙合)患者10例,其中男性4例,女性6例,年龄最小10岁,最大2l岁,前牙反(牙合)的数目平均4枚,上述病例下牙列均无明显畸形,后牙咬合关系基本正常,前牙咬合关系均呈深度反(牙合),上唇有不同程度内陷,颞颌关节的x线显示无明显异常。
Occlusal anterior teeth are more common in dento-maxillofacial deformities, especially in deciduous teeth, permanent teeth alternating period and permanent dentition early. When the number of anti-occlusal (occlusal) and anti-occlusal (occlusal) teeth is too large for the anterior (occlusal) occlusion of the anterior teeth, the satisfactory results can not be obtained because of complicated operation, poor comfort and long treatment time. We achieved a better curative effect by applying fixed and active appliance for the treatment of anterior crossbite. A clinical data of patients with anti-occlusion 10 cases, including 4 males and 6 females, the youngest 10 years old, maximum 2l years old, the average number of anti-occlusion (ankle) an average of 4 cases, the above cases of dentition There was no obvious deformity. The occlusal relationship of posterior teeth was basically normal. The occlusal relationship of anterior teeth showed deep anti-occlusion (occlusion), and the upper lip had different degrees of invagination. The x-ray of temporomandibular joint showed no obvious abnormalities.
