What Does a Dental Laboratory Technician Do?

There are several vital roles in dentistry, each with a different emphasis. If you’re interested in the oral care field, there are career opportunities to match every interest and aptitude. For students with a passion for science and artistry, a job as a dental laboratory technician may be particularly rewarding. Let’s look deeper at this exciting occupation and what you’ll learn in a training program.

What Does a Dental Laboratory Technician Do? 

Dental laboratory technicians create dental prosthetics and restorations, such as dentures, bridges, crowns, and veneers, based on specifications provided by a dentist. These custom-made appliances help restore oral function, improve aesthetics, and enhance patients’ overall health. It’s an expansive role. The work includes:

Material Selection

A quality dental appliance product requires appropriate materials. Dental technicians work with ceramics, metal alloys, acrylics, and resins, choosing suitable compounds based on strength, durability, biocompatibility, and appearance. The goal is to reproduce the patient’s natural teeth shape, size, and color.

Modeling and Waxing

Waxing and carving are steps in creating dental prosthetics of all kinds. Each involves using dental materials to sculpt replicas of restorations before they are cast or printed in the designated final material. Although they refer to different steps in the same process, waxing and carving are often used interchangeably in dental laboratory work.

Casting

Dental technicians cast metal alloys using specialized equipment, melting and injecting the metal and molding it into the desired shape for dental prosthetics involving metal components, such as crowns with metal posts.

Ceramic Layering

Ceramic layering, or porcelain build-up, is a technique dental laboratory technicians use to create the outermost layer of dental restorations. The purpose is to recreate the healthy appearance of natural teeth by applying layers of ceramic material onto a metal framework or high-strength ceramic core. After applying each layer, fire fuses the ceramic together to impart a natural translucence. The dental technician may add stains or glazes to enhance color and texture to optimize aesthetics.

Orthodontic Appliance Fabrication, Cleaning and Maintenance

Dental laboratory technicians may also create removable orthodontic appliances that aid in correcting jaw and tooth misalignment. Examples include retainers, splints, and aligners.

What Diploma or Degree Will Help Me Become a Dental Laboratory Technician?

There are several options to choose from so review each to determine which best fits your needs.

Diploma in Dental Laboratory Technology

Diploma programs in dental laboratory technology offer focused training in the skills required for entry-level positions. Offered by universities, full-time students can graduate in sixteen months. You will be out of the classroom and in the field quickly, making it a perfect option if you do not have years to dedicate to getting an education.

Associate Degree in Dental Laboratory Technology

Associate degree programs provide a more comprehensive education in dental technology. Available at universities, the curriculum includes dental technology and general education courses.

The associate degree in dental technology takes two years to complete. If you have the time, a degree program will provide a solid foundation for advanced roles in dental laboratories.

What Do You Learn During a Dental Laboratory Tech Diploma Program? 

Diploma programs cover the same topics as associate degree programs but must be more in-depth. Introduction, material, and clinic courses are combined into a single course. Students spend less time in school but need to learn more on the job. The expectation is that graduates will take entry-level positions.

Final Thoughts 

Oral care is an exciting and evolving field, but not every role requires filling cavities. If you prefer test tubes to toothbrushes, a career as a dental laboratory technician may be a perfect fit.
