The correct sequence for selective grinding when adjusting the occlusion of dentures focuses on ensuring that the occlusion is optimal during various jaw movements. Starting with centric occlusion is essential because it represents the maximum intercuspation where the upper and lower dental arches interdigitate fully. Adjustments made at this stage provide a foundational reference point for the occlusion, ensuring that the denture functions properly in its most stable position.

Following this, the working side is addressed, where modifications are made on the side of the jaw that is currently providing the primary occlusal load during mastication. This step is critical in creating a harmonious occlusion that allows efficient chewing on that side.

Next, balancing adjustments are made to ensure even contact on the opposite side during mastication, which prevents tipping or instability of the denture. This consideration helps in maintaining a comfortable fit and function.

Finally, protrusive adjustments are made, which focus on the occlusion when the jaw moves forward. This stage is vital for ensuring that there are no interferences during the forward movement of the jaw, which is necessary for a smooth and functional occlusion during various movements.

Together, this systematic approach helps in achieving a clinically acceptable occlusion that enhances the function and comfort of dentures.
