Dental technicians construct and repair dentures (false teeth) and other dental appliances including crowns and bridges.
Dental technicians work closely with dental prosthetists and dentists in the construction, modification and repair of dentures and other dental appliances.
Dental technicians may perform the following tasks:
- Make models of the mouth and teeth from impressions of the patient's mouth (taken by the dental prosthetist [clinical dental technician] or dentist);
- Build up wax replicas of part of all of the mouth and/or teeth on the model;
- Encase the wax in a mould material and melt away the wax;
- Replace the wax with either plastic, metal or ceramic materials to make the replacement appliance;
- Polish and finish the appliance prior to it being placed in the patient's mouth; and
- Make appliances for patients with cleft palates, braces and plates for correcting irregular teeth and mouthguards.
Dental technicians usually have no direct contact with patients unless they undertake further study to qualify as dental prosthetists (known in South Australia as clinical dental technicians).
Dental technology may be divided into the following areas:
- General Prostheses - the largest field in dental technology in which partial or full dentures (metal and non-metal) are constructed to replace the partial or total loss of natural teeth;
- Crown and Bridge - used in the restoration of the natural teeth and fixed in the patient's mouth;
- Orthodontics - the manufacture of fixed or removable appliances for the correction of dental irregularities in the child and young adult mouth.
- Maxillo-Facial - prostheses are made to replace missing facial and body tissues due to injury, disease or development abnormality; and
- Implantology - implants are placed directly into the patient's jawbone and prostheses are made to fit these implants. This system can be used for single, multiple or complete restorations.
