Abstract

Skeletodental asymmetries are common and asymmetric orthodontic treatments are very difficult to correct successfully. The cause of asymmetries can be the skeletal asymmetry, dental, or functional, or combinations of these causes. Skeletodental asymmetries can be the result of congenital factors, such as hemifacial microsomia and environmental factors, such as trauma. Optimal treatment outcome of the severe facial asymmetry requires the orthognathic surgery. Mild asymmetry problem can be treated by only orthodontic treatment. The orthodontic treatment of asymmetry is usually difficult. Facial asymmetry orthodontic treatment are primarily based on proper diagnosis and careful treatment planning. Side effects of asymmetric elastic to treat midline discrepancies are canted occlusal plane, tipped incisors and unesthetic results. In the management of dental arch asymmetries, the clinician should select the appropriate force system and the appliance design necessary to address the asymmetry while minimizing undesirable side effects. This report presents treatment strategies for the treatment of skeletodental asymmetry. In this case report, the clinical case with midline discrepancies treated by optimal mechanics is described. Through diagnosis and strategic treatment mechanics can obtain proper midline correction with minimal side effects.

비대칭은 두개안면증후군 같은 선천적 요인과 외상과 같은 환경적 요인에 의해 발생할 수 있으며 심한 골격성 비대칭에서부터 경미한 치열 비대칭에 이르기까지 그 정도는 매우 다양하며 이에 대한 환자의 인지 또한 주관적이다. 심한 비대칭의 경우 악교정 수술이 필요할 수도 있으나 비대칭이 심하지 않고 환자가 수술을 원하지 않을 경우 교정치료 만으로 비대칭의 개선을 도모할 수 있다. 하지만 비대칭 고무줄을 사용한 통상적인 방법으로 장기간 치료하면 교합평면이 기울어지거나 치아가 경사이동이 되는 등의 부작용이 발생하여 만족스럽지 못한 결과를 초래할 수 있다. 이를 예방하기 위해 초진 시부터 주의 깊은 진단과 충분한 역학적 고려를 포함한 철저한 치료 계획이 필요하다. 이에 하악의 편위가 발생한 안면 비대칭 환자에서 수술 없이 비대칭을 악화시키지 않는 조절된 교정력을 적용하여 만족스런 비대칭 절충 치료 결과를 얻었기에 이를 보고하고자 한다.
