치주영역에서의 교합기능은 치주조직의 유지에 필수적이며 교합력이 치주조직의 적응한계를 초과하는 경우 치주조직의 파괴가 유발되며 이러한 현상을 교합성외상, 교합성외상에 의한 병소라고 한다. 교합성외상에 의한 조직파괴양상은 염증성 치주질환과는 많은차이를 보이며 그 원인과 시간에 따라 분류되기도 하며 치주조직의 건강에 영향을 미치는 교합성외상의 영향과 치료과정에 대해 간략하게 살펴보고자 한다.

Trauma from occlusion (TFO) is a pathologic alterations which develop in the periodontium as a result of undue masticatory force. The purpose of this article is to review the controversies about TFO. There are evidences that TFO is a risk factor in the progression of periodontitis. Tooth mobility should be reduced by selective occlusal adjustment. TFO can be developed dependent on the masticatory pattern, occlusion and anterior overbite in sound periodontal conditions. Secondary TFO may aggravate unstable occlusion. If "loss of posterior support" was occur, the problems were worsen. Extrusion, migration, rotation and pathologic deviation can be resulted. Opposite contention is the "shortened dental arch" concept. However, these two concepts persue the occlusal stability together. To treat TFO adequately, exact diagnosis and multi-disciplinary treatment should be needed.

교합의 부조화는 외상성교합을 야기시킬 뿐만 아니라 치태의 침착을 용이하게 하며 일단 침착된 치태의 제거에도 애로점이 있고 외과적으로 치주낭을 제거하기 위한 술식을 적용할 때에도 문제점이 있다. 따라서 교합의 부조화를 치료해주는 교합치료는 완벽한 치주처치를 위한 중요한 한 분야이다. 특히 치주과 영역에서 외상성교합의 처치는 필수적이며, 그 방법도 대단히 다양하다. 외상성 교합의 증상에 따라서 치료방법을 선택하자면 다음과 같다. 우선 치은조직에 치은퇴축 혹은 형태의 이상이 야기되었을 때에는 이에 따라 외과적인 처치가 선행되어야 함은 물론이며 다음 단계가 치아의 위치이상을 교정적인 처치를 통하여 정복하거나 동요치를 안정시켜줄 필요가 있으며 또한 정확한 교합조정술이 필요하다. 교합조정술에 대한 제반 사항과 술식에 대하여는 본지, 1982년도 6월호에 상세히 언급되었으므로 본 원고에서는 교정적인 처치방법과 치주고정장치의 적용에 대하여 기술 하고자 한다.

부정교합으로 인한 외상성 악관절증은 비수술적 방법으로 개선되어야 하고, 악골기형성 부정교합은 수술에 의한 개선방법이 강구되어야 한다.

Trauma from occlusion(TFO) is injury to the periodontal tissue as a result of occlusal forces. Mobility is a common clinical sign of occlusal trauma. In acute occlusal trauma, this may be accomanied by pain, tenderness to percussion, thermal sensitivity, and pathologic tooth migration. Chronic occlusal trauma may be marked by excessive wear and gingival recession. Radiographic finding include a widened periodontal ligament space, radiolucence and condensation of the alveolar bone and root resorption. TFO is related to the pathogenesis of periodontal disease. It can cause increased tooth mobility TFO itself does not initate or aggravate marginal gingivitis or initiate periodontal pockets. Active trauma can accelerate bone loss, pocket formation and gingival recession depending on the presence of local irritants and inflammation. Gingival recession associated with occlusal forces includes traumatic crescent, McCall's festoon and Stillman's cleft. TFO plays a minor role in the pathogenesis of early to moderate periodontitis. A 5-year-old male visited Yonsei University Pedodontics clinic with a chief complaint about gingival recession. Mobility, excessive wear, gingival recession were detected by clinical exam on the both mandibular deciduous ca nine. On the radiographic view, vertical alveolar bone loss was observed on both mandibular deciduous canine.

Physiologic tooth attrition is accepted as a natural change. But when pathologic changes, such as loss of occlusal vertical dimension, masticatory pain, loss of masticatory function, and loss of esthetics occur, restorative measures should be taken by dentist. A patient visited the clinic with the chief complaint of 'My lower teeth bite the palate and it hurts'. It was diagnosed as iatrogenic attrition of lower natural dentition caused by inappropriate upper restorations, resulting in traumatic overbite. Through model analysis and diagnostic wax up, increase in vertical dimension was decided. Upper and lower dentitions were restored with new prostheses. After restoration, satisfactory outcomes were achieved both in functional and esthetic aspects.
