A dental prosthesis is an intraoral (inside the mouth) prosthesis used to restore (reconstruct) intraoral defects such as missing teeth, missing parts of teeth, and missing soft or hard structures of the jaw and palate. Prosthodontics is the dental specialty that focuses on dental prostheses.
There are removable and non-removable prosthetis.
Removable ones are known as dentures. A denture is a removable replacement for missing teeth and surrounding tissues. Two types of dentures are available — complete and partial dentures. Complete dentures are used when all the teeth are missing, while partial dentures are used when some natural teeth remain.
Non removable ones are known as crowns or bridges. A dental crown is a tooth-shaped “cap” that is placed over a tooth — to cover the tooth to restore its shape and size, strength, and improve its appearance.The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line. Bridges are commonly used to replace one or more missing teeth. They span the space where the teeth are missing. Bridges are cemented to the natural teeth or implants surrounding the empty space. As with crowns, you have a choice of materials for bridges.
