A dental core restoration involves the use of restorative material to rebuild a significantly damaged tooth structure. This procedure aims to provide adequate support and retention for a subsequent indirect restoration, such as a crown. For example, if a tooth has extensive decay or a large fracture that compromises its structural integrity, a dental professional will employ a filling material, often composite resin or amalgam, to replace the missing tooth volume and create a stable foundation.
The principal advantage of this technique lies in its ability to salvage teeth that might otherwise require extraction. By restoring the tooth’s form and strength, the procedure allows for the placement of a crown, extending the tooth’s lifespan and functionality. Historically, various materials have been used for this purpose, evolving from amalgam to resin-based composites, each offering different characteristics in terms of strength, aesthetics, and bonding capabilities.
