Dental Technician

Dental technicians are skilled craftspeople who make and repair dental restorations such as dentures, bridges, crowns, fillings, braces and other orthodontic correction appliances. They follow the directions or prescriptions of a dentist and do not deal with patients themselves.

When a denture has to be made, the dentist obtains impressions of the patient’s gums and palate, from which the technician makes a model. After this has been modified for comfort, the final denture is cast in an acrylic material or artificial resin. The appliance made often affects the appearance of the patient, which means that the work needs to be very precise and neat.

First they need to read prescriptions or specifications and examine models or impressions to determine the design of the dental products to be constructed.  They create a model of the patient's mouth by pouring plaster into a dental impression and allowing the plaster to set. They melt metals or mix plaster, porcelain or acrylic pastes and pour materials into moulds or over frameworks to from dental prostheses or apparatus.  

Dental technicians fabricate, alter or repair dental devices, such as dentures, crowns, bridges, inlays or appliances for straightening teeth. They prepare metal surfaces for bonding with porcelain to create artificial teeth, using small hand tools, and load newly constructed teeth into porcelain furnaces to bake the porcelain onto the metal framework. They place tooth models on apparatus that mimics bite and movement of patient's jaw to evaluate functionality of model. 

Other tasks are to test appliances for conformance to specifications and accuracy of occlusion, using articulators and micrometers, and to prepare wax bite blocks and impression trays for use, mould wax over denture setups to from the full contours of artificial gums, rebuild or replace linings and wire sections or missing teeth to repair dentures.  They apply porcelain paste or wax over prosthesis frameworks or setups, using brushes and spatulas, and fill chipped or low spots in surfaces of devices, using acrylic resins.  They also need to train or supervise other dental technicians or dental laboratory bench workers.

Dental technicians may be generalists and perform all types of dental laboratory work or may specialise in one of the following areas:

  • Prosthetics

  • Crown and bridgework

  • Metal framework

  • Orthodontics


  • private and commercial dental laboratories

  • dentists

  • hospitals and clinics

  • government departments

  • manufacturers of dental laboratory equipment and materials

  • self-employment, with enough experience and capital, can set up own practice
