颞颌关节对颌面部的生长发育非常重要,如两侧的关节均有异常,往往造成下颌骨发育不良而形成上颌前突,呈现所谓鸟咀状容貌。若是单侧性的异常,则表现为面部左右不对称,咬(牙合)平面、牙弓、基骨弓歪斜。以往对单侧性下颌骨发育不良的患者多数采用外科手术治疗。作者介绍用机能的颌矫正法进行治疗,对面部的不对称和咬(牙合)功能的改善获得一定的效果,并报告了病例。一例面部不对称的8岁11个月的女孩,检查发现下颌向右偏,右下颌角的位置高于左侧,颏部后退,张口时下颌明显地偏向右侧。上颌正中线向右偏位约2.5毫米,咬(牙合)平面右侧比左侧高,前牙复(牙合)约4毫米、复
Temporomandibular joint growth and development of maxillofacial region is very important, such as both sides of the joints are abnormal, often resulting in mandibular dysplasia and the formation of maxillary protrusion, showing the so-called bird-like appearance. If unilateral abnormalities, the performance of the left and right facial asymmetry, bite (occlusal) plane, dental arch, skeletal arch skew. In the past on unilateral mandibular dysplasia most patients with surgical treatment. The authors describe the use of functional orthognathic correction for the treatment of facial asymmetry and bite (occlusion) function to achieve some improvement, and reported the case. A case of asymmetric face 8-year-old 11-month-old girl, check the jaw to the right side of the deviation, the right mandibular angle position higher than the left, chin retreat, jaw mouth significantly shifted to the right side. Upper right midline deviation to the right about 2.5 mm, bite (occlusal) plane right than the left high, anterior teeth complex (occlusal) about 4 mm, complex
