Dental crowns, commonly referred as a ‘cap’ covers part of or the complete tooth. Different materials can be used to make the crown depending on the requirements such as function, aesthetics, patient preference and the condition of the tooth.
Zirconia ceramics provide the best aesthetics and stability but are also the most expensive of the materials.
Dental bridge is a dental restoration used to replace a ‘gap’ due to missing tooth/teeth. The adjacent teeth are used to hang the bridge. Several designs and materials are used for bridge fabrication depending on the size of the gap, aesthetics and function.
Removable prosthodontics is concerned with prosthesis which replace the soft tissues as well as teeth and are more commonly referred to as dentures.
These can be replacing all of the missing teeth (complete dentures) or may be replacing some of the teeth (partial dentures).
Both of them can be replacing either the upper or lower arch or both. They are made solely of plastic (acrylic) or can be made of combination of metal and plastic.
