It deals with restoring or replacing missing teeth with prosthetic devices constructed by the dental technician according to the doctor's precise indications.

ProsthesisIt is of the fixed type, cemented or screwed, when it is supported by implants or cemented on natural teeth. These are ground to reduce their volume which will be replaced with that of a crown usually made of gold-ceramic, or more modernly with zirconia-ceramic or all-ceramic.

A removable type is when the prosthetic device is designed to be removed from the oral cavity. If it replaces the entire dental arch, it will be a complete denture; if it replaces only some teeth, it will be a partial denture, made entirely of acrylic material or structured with a metal part called a framework. Removable dentures are now almost always replaceable with fixed ones, in which case they are supported by implants.
