Two Phase Orthodontic Treatment: A Case Report.

ABSTRACT

Myofunctional appliances become active through muscular forces that bring about the dentoalveolar and skeletal changes. Functional appliances can be both removable or fixed. Twin block appliance given by William Clark is one of the most popular functional appliance owing to its ease of fabrication for the orthodontist and its ease of wear for the patient. It is known to bring about both skeletal and dental changes and has been used extensively in Class II growing patients. This was a case report of a 12-year-old patient treated in two phases, first the functional phase using the twin block, followed by the second phase of fixed orthodontic appliance.
