Abstract

$T4K^{TM}$(Myofunctional Research Co, Australia) is one of the myofunctional appliance developed to be used in children of mixed dentition. Myofuncitonal appliance stimulate the facial, masticatory and tongue muscle and help to balance the muscular force. Labial bow included in the device exerts strength in excessively labial inclineded upper jaw, Lip bumper blocks strength of the mouth to prevent abnormal strength exerted in lower jaw, Tongue tag secures proper position of tongue, and additional exercise is not required for child patients. For the more, simpler design and softer texture of device prmoted cooperation of patients during use. This case report is to present the satisfactory results gained by using $T4K^{TM}$ on Class II patients. Comment 1. $T4K^{TM}$ was applied in Class II malocclusion patients of mixed dentition with expected space insufficient to gain facial improvement. 2. Excessive overjet, overbite were improved. 3. Main effects are regarded to have been achieved by development of lingual slant of upper jaw, labial slant of lower jaw, and lower part of jawbone. 4. Bad habits, such as mouth breathing, can also be adjusted.

T4K는 혼합치열기의 2급 부정교합 환자에게 사용되는 기능성, 가철성 교정장치이다. 기능성 교정장치의 경우 치열과 악골의 성장에 영향을 주는 구강안면부의 근육의 부조화를 개선시키는 역할을 한다. T4K에 포함된 lip bumper는 과도한 하순의 힘을 차단하여 주고, 하순 내측 전정을 자극하는 요소가 포함되어 있다. 부적절한 혀의 위치를 교정할 수 있는 요소는 환자들이 장치를 장착하는 동안 부가적인 혀 운동을 할 필요성을 감소시킨다. 2급 부정교합 환자의 경우 하악 열성장을 동반하는 경우가 대부분을 차지한다. 이 장치는 상악 치아를 고정원으로 하여, 하악을 전방으로 성장할 수 있도록 자극하여 부족한 하악 성장을 촉진하는 역할을 하고 있다. 이와 함께 부가적으로 Labial bow와 같은 역할을 하는 요소는 상악 치열의 개선에 도움을 준다. T4K는 기성품으로 작은 부피와 부드러운 질감으로 어린 환자들의 장착 동의율을 높이는 데 장점을 가진다. 원광대학교 치과대학 산본치과병원 소아치과에 내원한 혼합치열기의 2급 부정교합 환자에서 만족스러운 결과를 얻었기에 이를 보고하는 바이다. 요약 1. T4K를 혼합치열기의 2급 부정교합 환자에게 사용하여 안모의 개선을 얻었다. 2. 과도한 수직, 수평 피개교합이 개선되었다. 3. 하악 열성장 환자에서 T4K를 장착하여 하악 성장을 촉진하는 결과를 얻었다. 4. 구호흡 등과 같은 구강악습관의 개선을 얻었다.
