2- What Actually Determines Tooth Position
In "Equilibrium Theory Revisited," the video updates a classic dental concept. It discusses the landmark 1978 study on the Franco-functional regulator (FR1) for treating class 2 malocclusion in pre-pubertal children. Key findings include:
- Use of FR1 appliance resulted in a forward shift of the mandible.
- Reduction in overjet and improved soft tissue balance were observed.
- Study limitations: no randomization, no blinding, and simple statistical analysis.
The study highlights how early functional treatment affects tooth position, muscle balance, and facial posture, emphasizing that the FR1 guides growth rather than creating new bone.
