What is the primary purpose of a bite registration in prosthetic fabrication?

• A. Record the occlusal relationship between the maxillary and mandibular arches to establish correct occlusion on the model and prosthesis
• B. Determine the shade of the teeth
• C. Provide a wax pattern for crown fabrication
• D. Measure the width of the dental arch

Answer: (A)

The main idea is to capture how the upper and lower teeth meet so the prosthesis can be made to fit and function with the patient’s bite. A bite registration records the occlusal relationship between the maxillary and mandibular arches, allowing the dental casts to be mounted on an articulator in the same position the patient has when the teeth come together. This ensures the final restoration or denture has accurate occlusal contacts and proper guidance, so it functions smoothly in the mouth. Tasks like shade matching, waxing a pattern, or measuring arch width involve different steps and materials, not the bite registration itself.
