치아의 배열과 교합을 이상적으로 형성해 줌으로써 안모의 기능과 심미성을 개선할 수 있다는 Angle paradigm은 연조직을 중시하는 soft tissue paradigm으로 전환되고 있다. 이와 같이 연조직의 중요성은 증가하고 있으나, 아직까지는 직접적으로 연조직에 개입할 수 있는 비외과적인 수단이 없었다. 이러한 관점에서 보툴리눔 독소(이하 BTX-A)의 효과는 심미와 기능적인 요구를 충족시켜야 하는 교정치료에 유용하게 적용될 수 있다. 즉, 교합력을 감소시키기 위해서, 혹은 근육의 과활성을 개선하기 위해서 사용할 수 있으며 근육의 부피를 감소시켜 심미성을 증진시키기 위해서도 사용할 수 있다.
Botulinum toxin type A (BTX-A), a potent neurotoxin that reversibly blocks presynaptic acetylcholine release, has been applied successfully to treat facial spastic conditions such as blepharospasm, strabismus and cervical dystonia. Since the first reported application in dentistry in 1994, BTX-A has been used with great success to used in the orofacial region to help treat masticatory and facial muscle spasm, severe bruxism, facial tics, and hypertrophy of the masticatory muscles. The clinician may be aware of the many courses becoming available and aimed at dentists to start using it in the cosmetic context. This article intends to provide a basic understanding of the many functional uses of the drug in the orofacial region that may be relevant to everyday practice, especially in orthodontic field.
