The National Association of Dental Laboratories became established in a Chicago merger between the American Dental Laboratory Association and the Dental Laboratory
Institute of America in 1951, according to the NADL website. The National Association of Dental Laboratories sponsors programs and services to its members concerning the technical, educational and professional business aspects of the dental laboratory industry.
From archaeological evidence, early humans did not get cavities, probably because they did not eat refined sugar. However, they did have poor teeth due to their diet, which contained lots of sand and dirt wearing down the teeth. (Source: James Wynbrandt, "The Excruciating History of Dentistry," St. Martin's Griffin, 2000, p. 4.)
Modern people are saved from tooth wear by cleaner foods but suffer the consequences of less nutritive and more invasive diets that include sugar-causing cavities and tooth decay. This leads to the need not only for dentists to deal with teeth problems on the front lines, but a need for dental technicians to make sophisticated tooth replacements and repair older dental appliances.
The American Dental Association recognized 20 different programs in 2006 that were accredited to train dental laboratory technicians. At these institutes, prospective
candidates receive training through classroom instruction and in a dental laboratory. Students learn how to complete basic procedures and cover topics such as dental materials science, oral anatomy, ethics and other related dental subjects. Accredited programs typically take two years to complete, but several are designed as four-year programs.
Dental Laboratory Technology is both a science and an art. Since each dental patient's needs are different, the duties of a dental laboratory technician are comprehensive and varied. Although dental technicians seldom work directly with patients, except under the direction of a licensed dentist, they are valuable members of the dental care team. They work directly with dentists by following detailed written instructions and using impressions (molds) of the patient's teeth or oral soft tissues to create.
