Before relining a complete denture, what is the first step to establish?

• A. Maxillary vestibular extension
• B. Anterior occlusion
• C. Posterior occlusion
• D. Lateral occlusion

Answer: (C)

The primary step before relining a complete denture is to establish the posterior occlusion. This is crucial because it ensures that the back teeth of the denture meet correctly during function, which plays a significant role in achieving a stable, balanced occlusion. Proper posterior occlusion is essential for maintaining the overall functionality of the denture, as it affects how forces are distributed during chewing and speaking. If the posterior occlusion is not correctly set, adjustments may need to be made to ensure that the denture fits properly against the underlying tissues, which can help prevent issues such as discomfort or instability when the patient uses the denture. Once the posterior occlusion is established appropriately, other factors such as anterior occlusion and lateral occlusion can be addressed to optimize the overall fit and comfort of the complete denture.
