摘　　要：错[牙合]畸形的早期矫治包括对患者骨骼畸形进行生长改良、对部分牙齿问题及口腔不良习惯进行预防性及阻断性矫治,以引导牙颌面的正常发育、消除错[牙合]畸形对口颌系统功能的不良影响以及对牙齿与牙周组织健康的损害。虽然所有错[牙合]畸形均可于恒牙期开始进行正畸综合治疗,但由于恒牙初期时相当一部分患者仍处于生长发育期内,对部分错[牙合]畸形仍可采用早期矫治的手段进行治疗,而且这一阶段的正畸治疗具有一定优势。本文针对恒牙初期可行早期矫治的下颌发育不足所致的骨性Ⅱ类错、上颌发育不足所致的前后牙反[牙合]等错[牙合]类型进行论述,以期为临床提供参考。The early orthodontic treatment of malocclusion includes the growth modification of skeletal discrepancy,preventive and interceptive orthodontic treatment of the dental malocclusion or oral habit.Therefore,early orthodontic treatment is to guide the normal dento-maxillafacial growth and development,eliminate the adverse effect on function of masticatory system and the health of dental and periodontal tissues.Most of the patients in the early permanent dentition are still in their pubertal growth period.Although all kind of comprehensive orthodontic treatment could be started from early permanent dentition,early orthodontic treatment can still be used in the cases such as classⅡmalocclusion caused by underdevelopment of mandible and crossbite caused by underdevelopment of maxilla in the early permanent dentition.The article will discuss classⅡmalocclusion caused by underdevelopment of mandible and anterior and posterior crossbite caused by underdevelopment of maxilla which are feasible for early orthodontic treatment.
