골유착된 견치의 교정적 치험례

The treatment of an ankylosed canine : Luxation and forced eruption

본 증례는 외상으로 골유착된 견치를 탈구와 인위적 맹출 유도로 치료한 환자에 대한 것이다. 초진시에는 견치가 골유착되었다는 어떠한 증거도 발견되지 않아 하악에 가철실 장치와 악간 고무줄을 이용하여 인위적 맹출을 시도하였으마 3개월후에도 전혀 움직임을 보이지 않았다. 이 시기에 견치는 생리적인 움직임을 전혀 보이지 않았고 타진시 날카로운 울림소리가 나는 것으로 골유착되었음을 확인하였다. 이에 골유착된 견치를 탈구시키고 인위적 맹출을 즉시 도모하여 교정적, 치주적으로 양호한 결과를 얻었기에 이에 보고하는 바이다.

This paper outlines the case of a 56 year-old man undertaking teratment by means of luxation and forced eruption of an ankylosed canine. At the time of diagnosis, the ankylosis of the tooth was not suspected, because there were not signs of intrusive luxation nor horizntal diaplacement. Only after the application of a vertical force failed to erupt the maxillary left canine, was the ankylosis of that tooth suspected. At the time of reevaluation, the maxillary left canine hads no physiologic tooth mobility and emitted a sharp, ringing sound upon percussion. Hence, the maxillary left canine was considered ankylosed. The treatment course then changed to the extrusion of the canine through the sugical luxation of the tooth and the prompt application of vertical extrusive forces. The above outcome was successful for the patient only in the orthodontic aspect, but also in terms of the periodontal considerations.
