Lecture Description
Class II orthopedics with functional appliances has been established as a primary treatment modality for growth modification since 1930s. Although, some updated evidence on the treatment effects of functional appliances has shown skeptical aspects regarding long term response and predictability of mandibular growth. The goal of functional orthopedics in the treatment of skeletal Class II is to provide normal functional environment inducing advancement of tongue, enlargement of the constricted upper airway, and favorable muscle response which would ultimately stimulate mandibular growth. It is impossible to expect mandibular growth beyond genetic potential by growth modification, however it is critical to eliminate any epigenetic factors which would exacerbate skeletal discrepancy.
Understanding the mandibular growth rate and morphologic changes is essential for determination of timing of functional orthopedics. Up to now, it is well known that the timing of successful Class II growth modification is pubertal growth spurt. Most previous studies have focused on the age of patients in preadolescent, adolescent, and post adolescent based on puberty, and there has been no studies on functional orthopedics in early childhood or infancy. In this presentation, the greater potential of mandibular growth in infants and early childhood is highlighted and it will be further discussed whether this period can be considered as a window of opportunity for early treatment.
Learning objective
- Understand the pattern of mandibular growth from birth to post-adolescent
- The possibility of Class II functional orthopedics at a younger age before puberty
