Before relining a complete denture, what must first be established?

• A. Anterior guidance
• B. Maximum intercuspation position
• C. Posterior occlusion
• D. Centrifugal relation

Answer: (C)

Before relining a complete denture, it is essential to establish posterior occlusion. This involves ensuring that the occlusal surfaces of the posterior teeth are in correct contact when the patient closes their mouth, allowing for proper function and comfort. Proper posterior occlusion ensures that any adjustments made during the relining process will maintain an appropriate bite relationship, which is crucial for chewing efficiency, speech, and overall patient satisfaction with the denture. When posterior occlusion is correctly established, it sets a solid foundation for any modifications that will be made to the denture's fit and function. If this aspect is overlooked, it can lead to discomfort, altered occlusal relationships, and may require further adjustments post-reline. Establishing anterior guidance or maximum intercuspation position may be important in broader considerations of denture design and function, while centrifugal relation typically pertains to dental movements not directly involved in the immediate needs of denture relining. These factors are secondary and come after ensuring that the posterior occlusion is adequately addressed, making it the primary focus before proceeding with relining.
