Achieving a smooth, lustrous finish on Shera cast crowns and bridges is essential for both aesthetics and biocompatibility. This polishing process involves carefully removing surface imperfections through a multi-step approach.

The ultimate goal is to create a restoration that’s not just visually appealing, but also resistant to plaque accumulation, benefiting overall oral health.
