What does emery abrasive primarily do in a dental context?

Emery abrasive is primarily used for polishing in dental contexts, particularly for porcelain restorations. The abrasive is effective for refining the surface and providing a smooth finish, which enhances the aesthetic appearance of dental restorations made of porcelain. This is important because a polished porcelain surface not only looks better but also helps in reducing plaque accumulation and microbial colonization, contributing to overall oral health.

While other materials, like aluminum or composite resin, may require different types of abrasives or polishing agents, emery specifically addresses the needs of porcelain surfaces well, making the procedure efficient in restoring the gloss and shine to these restorations. The use of emery helps practitioners achieve a desired level of smoothness and polish which is critical for both functionality and appearance in dental materials.
