Polishing teeth before seating a partial denture is important because it enhances the adaptability of occlusal rests. When the surface of the teeth is smooth and polished, it allows for better contact and fit between the occlusal rests of the partial denture and the teeth. This improved fit is crucial for the overall stability and functionality of the denture, as it helps to ensure that the forces during chewing are properly distributed.

A well-polished surface can also minimize wear on both the denture and the natural teeth, contributing to a more efficient occlusion. Additionally, a smoother surface reduces the likelihood of plaque accumulation, which is essential for maintaining oral hygiene, but the primary reason linked to occlusal rests is the improved adaptability to the natural anatomy of the teeth.

While enhancing aesthetic appearance and reducing plaque retention are also beneficial outcomes, they are secondary to the critical role that proper fit and function play in the seating of a partial denture. Strengthening the denture material isn’t directly related to the polishing of natural teeth.
