Dental laboratories serve a crucial role in dental healthcare by fabricating dental appliances and restorations that are prescribed by dentists. These specialized facilities allow dentists to focus on examinations, procedures, and patient care while relying on the technical expertise of dental technicians. Some of the main functions of a dental lab involve the fabrication of crowns, bridges, dentures, retainers, mouth guards, and other customized dental devices.

Crown and Bridge Fabrication

One of the primary roles of a dental lab is to fabricate crowns and bridges prescribed by dentists. This process begins when an impressions of the prepared teeth is sent to the lab. Dental Laboratories will then pour dental stone into the impression to create a stone model of the teeth. For crowns, an wax replica of the crown is sculpted on the model to match the shape, size, and color of the surrounding teeth.

This wax pattern is then molded and invested in refractory material before the wax is melted away and replaced with dental porcelain or other restorative materials. The finished crown is then polished and shipped back to the dentist for cementation. For bridges, multiple crowns and a bridge retainer are fabricated and fitted together based on the prescription from the dentist.
