Prosthodontic crowns are used when all other options for crown restoration are unavailable. They are the most popular and most widely used element for fixing bridges, protecting and strengthening the tooth after endodontic treatment, and implant restorations.
Porcelain is considered the best material for the composition of dental crowns. Full-ceramic crowns are used on anterior teeth for aesthetic reasons. Such crowns contain no metal and therefore differ from traditional porcelain crowns. This is important because metal does not let light pass through the crown, which makes the restored tooth look unnatural. Instead of metal, the framework of full-ceramic crowns is made of porcelain, zirconium, or aluminum oxide.
