외골증은 골이 국소적으로 증식한 양성의 상태로, 구강 내에서는 하악 설측과 구개측 정중앙부에 가장 호발하여 각각 하악융기(torus mandibularis)와 구개융기(torus palatinus)로 명명한다. 정확한 원인은 아직 밝혀지지 않았으며, 유전적 요인과 과도한 교합력에 의한 환경적 요소를 그 요인으로 추정하 고있다. 구강내 외골증은 병적인 현상이 아니며 양성이므로 외과적인 제거가 꼭 필요한 것은 아니다. 하지만, 발음에 방해가 되거나 보철적으로 의치 제작에 방해가 되는 경우, 암공포증(cancerphobia)이 있거나 외상에 의한 만성 통증이 있는 경우, 그리고 골처치를 동반한 치주치료를 하는 경우 외과적인 제거를 고려하게 된다. 따라서, 임상적으로 외골증을 관찰할 경우, 올바른 진단과 제거 여부를 결정하는 것이 필요하다.
Bony exostosis, one of the osseous deformities, could act as a contributing factor of periodontal disease since it makes proper tooth brushing difficult and causes traumatic ulcer. The purpose of this case report is to show improvement of periodontal health by removal of bony exostoses and creation of physiologic osseous form. A 58 year-old female patient with recurrent ulcer and pain on bony exostoses located on left maxillary palatal area and both mandibular buccal areas was treated. Exostoses were removed and physiologically positive osseous form was created following vertical grooving, radicular blending, flattening interproximal bone and gradualizing marginal bone. The patient showed no further recurring traumatic ulcer and bone exposure. Moreover, periodontal pocket was eliminated and food impaction was decreased. In conclusion, periodontal health could be achieved through removal of multiple bony exostoses and development of ideal osseous form.
