The clinical models from these impressions may be created and mounted on an articulator, which simulates the jaw movements of the mandible.Īlan B. Today, as in the past, the communication tools between the dentist and the technician include photography, written documentation, and impressions of the patient's existing dentition.
Functional components, occlusal parameters, phonetics, and esthetic requirements are just some of the essential types of information that are necessary for technicians to complete the fabrication of successful, functional, and esthetic restorations. Throughout the entire restorative process, from the initial patient consultation, diagnosis, and treatment planning to final restoration placement, the communication routes between the dentist and the laboratory technician now can provide a complete transfer of information. The dental laboratory's primary role in restorative dentistry is to perfectly copy all of the functional and esthetic parameters that have been defined by the dentist into a restorative solution. Misch, in Dental Implant Prosthetics (Second Edition), 2015 The Dental Laboratory 70 The BLS estimated that in 2017 there were 35,630 dental technician jobs in the United States, a 38% reduction from about 60,000 technician jobs in 1996. Customarily, dental prostheses were made by hand by technicians using wax, acrylic, or other dental materials, but with the creation of computer-aided design and computer-aided manufacturing (CAD/CAM) of dental prostheses and outsourcing internationally, the use of dental laboratory technicians may be in decline as seen in their trends of employment. Most technicians now are employed by independent commercial laboratories, which provide their services to dentists. Over time, however, this arrangement became less cost-effective for most dentists. Traditionally, technicians were directly employed by dentists and worked in a laboratory in the same office as the dentist. 15 Technicians also may become certified dental technicians in one or more of the areas of complete dentures, partial dentures, crowns and bridges, ceramics, and orthodontics. 30 The programs have dropped in number from the 1990s, reducing annual graduates from over 600 to just 300 in 2016. In 2018, there were 15 dental technology programs in the United States accredited by CODA.
Laboratory technicians are trained on the job or in formal education programs. Many of these tasks require high precision, and the technician’s skill weighs heavily on the ultimate success of the treatment.
The dental laboratory technician’s task is to fabricate crowns, bridges, dentures, and orthodontic appliances based on the prescription of a dentist. Hannah Maxey PhD, MPH, RDH, in Burt and Eklund's Dentistry, Dental Practice, and the Community, 2021 Dental Laboratory Technicians
