In dogs and cats, the most common causes of dental injury are fights with other animals, car accidents, falls from a height, and chewing on hard materials such as bones or rocks. The trauma more often causes fracture of the teeth, but sometimes avulsion or luxation can occur. Avulsion is the complete displacement of the tooth out of the alveolar socket and luxation is the partial displacement of the tooth. Tooth luxation and avulsion represent dental emergencies. Time is an important factor for successful treatment; the prognosis becomes poorer the longer the tooth is out of the socket. This paper describes the guidelines for treatment of dental displacement in cats and dogs and presents six cases of dental lateral luxation in dogs seen at the Veterinary Hospital of the University of Pennsylvania (VHUP) in the period from May 1996 to September 1997.
在犬猫中，牙齿损伤最常见的原因是与其他动物打架、车祸、高处坠落以及啃咬骨头或石头等硬物。这种创伤更常导致牙齿折断，但有时也会发生牙齿脱出或松动。牙齿脱出是指牙齿完全从牙槽窝中移位，而牙齿松动是指牙齿部分移位。牙齿松动和脱出属于牙科急症。时间是成功治疗的重要因素；牙齿脱离牙槽窝的时间越长，预后越差。本文描述了犬猫牙齿移位的治疗指南，并介绍了1996年5月至1997年9月期间在宾夕法尼亚大学兽医院（VHUP）见到的6例犬牙齿侧方松动病例。
