Prosthodontics is the branch of dental medicine which deals with the substitution of one or more teeth with a prosthesis so to restore teeth’s functionality, but also the aesthetics of the mouth. In the case of tooth loss it is necessary to proceed with prosthesis’ placement, but there are also other cases in which crowns, veneers or bridges are used. All these elements are considered fixed prosthesis. Substituting missing teeth is of extreme importance to maintain correct chewing and pronunciation, but also for preserving the aesthetics of the mouth.
Various materials are used within dental prosthodontics, so apart from the classic metal-ceramics, used for fixed prosthesis, today we can choose ceramics without metal support and zirconium. Each of these materials offers different possibilities and particular aesthetic effects, so ceramic without metal support is more suitable for front teeth, veneers and crowns, as it offers the best aesthetics. On the other hand, zirconium, due to its sturdiness, can be used as support for ceramic crowns.
