Inter-Arch Treatment Mechanics, Part 2: Class III and Asymmetrical Treatment

This course will review Class III and asymmetrical treatment. The general concepts of diagnosis and treatment planning of Class III cases will be presented based on soft tissue, dental and skeletal parameters. Case presentations will then be evaluated relative to early treatment, full-banded non-surgical treatment and surgical treatment. Early treatment will focus on the use of Class III elastics, facemasks and skeletal plates. Full banded non-surgical treatment will discuss important issues such as anterior dental compensation, non-extraction treatment and extraction options, vertical and A/P relationships, the pubertal growth spurt and family history, and growth prediction based on the ratio of horizontal projection of A point relative to B point. The limits of non-surgical treatment will be discussed and some surgical cases will be presented. Asymmetrical cases will be discussed relative to the categories of anterior, posterior and combination of anterior and posterior dental asymmetries. Functional side shifts as well as skeletal asymmetries will be reviewed. Appliance variations for Class III and Asymmetrical cases will be discussed.
