If each tooth remains firm, does not wear excessively and stays in its proper position, then the occlusion is stable. The signs of instability are clinically recognizable as:
- Excessive Wear
- Migration (teeth moving either vertically or horizontally)
Signs of instability are really visible EFFECTS. For dental treatment to be complete, it must correct the CAUSE of each effect so that the equilibrium of the masticatory system can be re-established and optimum health of all components can be maintained.
