posterior bite blocks: Definition, Uses, and Clinical Overview
posterior bite blocks are temporary “platforms” placed on the back teeth (premolars and/or molars) to change how the upper and lower teeth meet. They are commonly used in orthodontics to open the bite (increase the space between teeth) during tooth movement. They can be made from bonded dental materials (often resin-based composite) or fabricated as part of a removable appliance. The goal is usually to guide occlusion (the bite) in a controlled way while other dental or orthodontic steps are performed.
