Study Notes
Orthodontic Tooth Movement
- Pressure from orthodontic appliances is the primary driver of tooth movement
- Mechanical stress applied during orthodontic treatment induces a biological response in the periodontal ligament (PDL)
- Osteoclasts are responsible for bone resorption, enabling tooth movement by breaking down bone on the pressure side of the tooth
Environmental Factors and Biological Response
- Magnitude of force applied significantly affects the biological response during tooth movement.
- Excessive force can lead to root resorption and other complications.
- Optimal force promotes efficient and predictable tooth movement.
Periodontal Ligament Response
- Periodontal ligament acts as a sensory organ, transmitting information about the applied forces to the surrounding tissues.
- The PDL undergoes remodeling in response to the forces, facilitating tooth movement.
- Cells within the PDL differentiate into osteoblasts and osteoclasts, contributing to bone formation and resorption respectively.
Orthodontic Treatment Phases
- Retention phase focuses on stabilizing the teeth in their new positions after active tooth movement.
- This phase is crucial for consolidating the changes achieved during the treatment.
- Retainers, fixed or removable appliances, are used to maintain the desired tooth position.
