Summary

Text I. Laboratory technicians.

 

Dental laboratory technicians are a part of a dental care “team” along with dentists, dental assistants and hygienists. They create dental prostheses – replacements for natural teeth. Their work enables people who have lost some or all of them to eat, chew, talk and smile much as they did before. The technicians fabricate prostheses which are designed to meet each patient’s specific needs. They do not work directly with patients, but follow detailed instructions provided by a dentist.

If a person has lost the most part of his natural teeth, the technicians make a complete set of dentures. If a person has lost only one or a few teeth, the technicians fabricate removable dentures or bridges. They also create crowns and other appliances in order to straighten and protect teeth. Technicians work with a variety of materials that needs skill in using small hand instrument, accuracy, attention to minute details.

There are two main educational routs to become a dental laboratory technician – academic programs and apprenticeships. If one takes the academic route, it is necessary to attend a two-year program at a community college, vocational school, technical institute or dental school. The first year curriculum includes the study of anatomy, chemistry, metallurgy, dental law and ethics, laboratory techniques. The second year course focuses on practice and experience in the laboratory techniques.

Those who want to become dental technicians must pass an examination in five areas – complete dentures, partial dentures, crowns and bridges, ceramics and orthodontics. According to the results they get specialization in one or more of these areas.
