Dental Laboratory Technicians Dental Laboratory Technicians Dental laboratory technicians make and repair dentures, crowns, and bridges that replace teeth. Dental laboratory technicians fill prescriptions from dentists for dentures, crowns, or replacement teeth for dental patients.
Some dental technicians perform every phase of the work.
They read prescriptions and check models and impressions of teeth sent by dentists. These models serve as patterns for the prosthetic teeth. When replacing a lost tooth, dental lab technicians build and shape a wax tooth. They use the wax model to cast the metal framework for the new tooth. Then they apply porcelain in layers to make the exact shape of a tooth.
