The basic data needed for orthodontic diagnosis and treatment planning include color prints of soft tissue facial profile, intraoral dental arches, and occlusion; cephalometric and panoramic radiographs; and dental casts. Hand-wrist and TMJ radiographs are also necessary in some circumstances. If orthodontic diagnosis and treatment plans are made only from the dental alignments and occlusion from the static or hand-assembled dental casts, the diagnosis and treatment planning made may be wrong in some cases. Clinically, it is necessary to find the centric relation of the lower jaw and to transfer the jaw relationship to the articulator. Correct diagnosis and orthodontic treatment planning may then be made from the findings of the occlusal relationship from the articulator accompanied with the information on skeletal age and craniofacial characteristics from the hand-wrist and cephalometric radiographs. Four clinical cases have been presented to demonstrate the importance of determination of jaw position in orthodontic diagnosis and treatment planning in adult patients.
正畸诊断和治疗计划所需的基本数据包括软组织面部轮廓、口腔内牙弓和咬合的彩色打印件；头影测量片和全景X线片；以及石膏模型。在某些情况下，手部-腕部和颞下颌关节X线片也是必要的。如果仅根据静态或手工组装的石膏模型上的牙齿排列和咬合情况来制定正畸诊断和治疗计划，那么在某些情况下所做的诊断和治疗计划可能是错误的。临床上，有必要找到下颌的正中关系，并将颌骨关系转移到咬合架上。然后，根据咬合架上咬合关系的检查结果，结合手部-腕部和头影测量X线片上的骨骼年龄和颅面特征信息，进行正确的诊断和正畸治疗计划制定。本文介绍了四个临床病例，以证明确定颌骨位置在成人患者正畸诊断和治疗计划中的重要性。
