[Measurement of orthodontic appliance force using prototype sensors]

Area of Science:

• Biomedical Engineering
• Materials Science

Context:

• Intraoral measurement of orthodontic forces requires understanding biomechanical principles.
• Acrylics are commonly used materials for orthodontic appliances.

Purpose:

• To investigate the mechanical properties of acrylics for orthodontic appliances.
