to the complexity of the work that is carried out by dental technicians, a professional generally specializes in one field of dental prosthesis. Since the range of devices to design and create is extremely varied, it would be impossible to make all of them with the same set of skills, further, to completely master any technique may require years of experience. In general, the first step a dental technician makes is to “master the plaster”, meaning that they first start in the part of the lab where dental impressions are made, cutting models, and mounting articulators. The dental technician may acquire the ability to carry out various and disparate tasks in the lab, being able to even execute most steps in the production of various prosthetics, such as removable partial dentures, complete and partially made of resin, and orthodontic devices (including braces and retainers). Nevertheless, as mentioned previously, dental technicians need to specialize; in fact, there are many specific dental labs that exist for each and every type of prosthesis. The distinct specialties are described below: Polisher A polisher is a dental technician who dedicates themselves to the setup of teeth, either in making removable prosthetics made of resin or metal, molding the neck of the tooth, or loading the resin. Within their profession, they can also be referred to as a waxer. Metalworker A metalworker is a dental technician who is in charge of casting dental rods, which means they mold the metal and obtain the metallic frames for fixed prostheses, similar to the removable prosthetics made of resin. They are also in charge of processing and reworking said metal. These professionals can also be in charge of designing the wax patterns of removable metallic prostheses, such as the copings of crowns and fixed bridges. Among other things, this depends on the dental technician and the lab in which they work. Prosthetic orthodontists It is very common to differentiate a prosthetist who works with removable orthodontics, as it is normal to find professionals who specialize in this field. Removable equipment consists of a variety of different devices, each with specific naming and characteristics. Prosthetic orthodontists should be both agile and precise when handling different pliers and manipulating wires. Ceramicist A ceramicist is a dental physician who has specialized in the final stage of making fixed prosthetics, which consists of the assembly of ceramic on different prosthetic structures such as:
