Which item is a form of bite plane used to adjust occlusion?

• A. Foxes bite planes
• B. Clear matrix
• C. Elastomer impression material
• D. Spatula

Answer: (A)

Bite planes are devices used to modify and test occlusion by providing a stable surface for the patient to bite against, temporarily displacing the mandible to identify and adjust premature contacts and the vertical dimension. The Fox bite plane is a specific form of bite plane—a simple acrylic plate with an occlusal surface that the patient bites on. This lets the clinician disocclude posterior teeth and assess how the bite should be adjusted, guiding occlusal equilibration or denture setup without altering the natural tooth structure. The other options don’t function as bite planes: a clear matrix is a restorative matrix for shaping composites, elastomer impression material is used for making impressions, and a spatula is a mixing/applying tool.
