Summary
Orthodontic forces trigger complex biological responses in teeth and surrounding tissues, involving cellular and molecular changes essential for tooth movement. This review synthesizes current research to clarify these mechanisms for clinicians and educators.
Area of Science:
- Biomedical Engineering
- Orthodontics
- Cell Biology
Background:
- Orthodontic tooth movement relies on remodeling of paradental tissues.
- Force-induced strain initiates vascular, cellular, and extracellular matrix changes.
- Numerous signaling molecules are released, including neurotransmitters, cytokines, and growth factors.
Purpose of the Study:
- To provide a concise convergence of current data on the biological basis of orthodontic tooth movement.
- To help clinicians and educators understand the underlying biological processes.
- To review major findings from the inception of research in this field.
Main Methods:
- Literature review and synthesis of existing research.
- Focus on cellular, molecular, tissue, and genetic responses to orthodontic forces.
- Brief review of bone, periodontal ligament, and gingival remodeling.
Main Results:
- Detailed insights into molecular, cellular, and tissue-level reactions to orthodontic forces.
- Highlights recent developments in biological responses.
- Explains the biological background of potential adverse effects.
Conclusions:
- Understanding the biology of tooth movement is crucial for effective orthodontic treatment.
- This review consolidates knowledge on cellular and molecular mechanisms.
- Informed application of orthodontic forces can optimize outcomes and minimize risks.
