Prosthetics is a specialist branch which deals with fixing functional and aesthetic imperfections of dental cavities. It is divided into mobile and fixed. Mobile prosthetics solves problems by dentures (partial, total) which are made of acrylate or combination of metal and acrylate. Partial denture can be anchored to remaining teeth with clips or special links (anchors). Fixed prosthetics is squeezing out the mobile prosthetics especially by fixing lack of teeth with implants. Fixed prosthetics implies creation of individual tooth crowns or several crowns linked to a dental bridge and is usually anchored by cementing to an abutment tooth or implant. Today the most common material used for making crowns and bridges is metal free ceramics. There is also ceramics on metal, where the metal construction is covered with ceramics. Inlays and on-lays are usually used to compensate for larger imperfections on teeth. They can be made of metal (golden alloy), composites and ceramics. Dental veneers are a prosthetic substitute which is usually glued to the visible part of the tooth. Because of its slim design and brittleness it is very important to choose the proper material and gluing type. I would especially like to point out that I always try to save the remaining roots of teeth and use them as carriers for crowns or dental bridges. Before that it is important to do an upgrade and I highly recommend casted individual metal upgrades (Wiron, gorld) or zirconium upgrades, because I personally find them more stable and permanent than ready-made shields and fiberglass upgrades. With only two good roots and casted upgrades a stable telescope prosthesis can be made. In my clinic we often make telescopes and they can be combine with existing teeth, implants etc.
