TWİN-BLOK APAREYİ

Ortodontide Sınıf II maloklüzyonlar en sık karşılaşılan anomalilerin başında gelmektedir. Büyüme ve gelişim döneminde; mandibular yetersizlikle karakterize Sınıf II Div. 1 maloklüzyonu olan hastalarda fonksiyonel ortopedik tedaviler sıklıkla uygulanmaktadır. Yaygın olarak kullanılan hareketli fonksiyonel apareylerden biri olan Twin-blok apareyi; alt ve üst çene olmak üzere iki ayrı akrilik plak ile beraber mandibulanın ileri hareketini sağlamaktadır. Diğer fonksiyonel apareylere göre; daha küçük olması, ön bölgede görünür akrilik kısmının olmaması ve konuşmayı minimal olarak etkilemesi vb. avantajlarından dolayı sıklıkla tercih edilmektedir. Twin-blok tedavisinin birçok iskeletsel, dişsel ve yumuşak doku etkileri görülmektedir. Bu derlemenin amacı; Twin-blok apareyinin kraniyofasiyal yapılar üzerine olan etkilerini incelemek, diğer fonksiyonel apareyler ile tedavi etkinliğini karşılaştırmak ve apareyin modifikasyonları hakkında bilgi sunmaktadır.

TWIN-BLOCK APPLIANCE

Class II maloclussion is one of the most common anomaly in orthodontics. Generally functional orthopedic treatment is applied to the patients with Class II Div 1 malocclusion that characterized by mandibular deficiency during growth and development period. One of the commonly used removable functional appliance is Twin-block appliance that include upper and lower two acrylic platesand improve forward movement of mandible. Twin-block is commonly preferred rather than other functional appliances, because of the advantages as to be small, the acrylic part is not visible in anterior and minimally affect speech. Twin-block treatment have many skeletal, dental and soft tissue effects. The purpose of this review was to observe the effects of Twin-blok appliance on the craniofacial structures, comparison of treatment effect with other functional appliances and Twin-blok appliance modifications
