Angle씨 분류 III급 부정교합의 임상적 고찰

CLINICAL CONSIDERATION OF ANGLE'S CLASSIFICATION CLASS III MALOCCLUSION

저자들은 III급 부정교합의 가족력이 있는 8세 6개월의 여아를 III급 부정교합의 초기상태에서 조기치료를 시도했고 계속적인 장치의 장착으로서 Growth spurts에 일어날수 있는 하악전돌증의 공적으로부터 이를 방어하고져 시도하였다. Growth spurts로 인한 하악전돌증의 방어를 효과적으로 하기위해서는 chin cap과 extraoral force의 이용도 적절하리라 생각한다.

Class III malocclusions are difficult to treat and take more time than any other types. But if such problems are detected at the earliest opportunity, we may gain the best possible correction consistent with the limitations imposed by morphogenetic pattern. The question of whether a patient has false or real Class III malocclusion is not important. Therapy wilt eleminate the malrelationship, in any event. Graber said, 'It has been my experience that many so-called 'pseudo' Class III's are full-blown Class III's later on during the prolific growth period.' The authors have attempted early treatment of a Class III malocclusion of 8-year old girl, who has the familial history of Class III malocclusion.
