Dental Laboratory Equipment

Denture manufacturing means small amount of material, but high amount of work involved in. Dental laboratories range in size from one-person firms to large assembly line operations. They are clean, well-lighted, and usually air-conditioned. This supports working atmosphere which is an important precondition for high quality work.

The premises of dental laboratories may include 3 rooms: a workshop, an office and a plant room that hosts the firing furnaces, the grinding machines, and other noisy devices. The plant room also has an oversized extractor fan similar to those in restaurant kitchens. Laboratory production of dentures produces lots of dust and fumes as well, which need to be vacuumed and exfiltrated.

Technicians usually have their own workbenches, which are equipped with Bunsen burners, grinding and polishing machines, and various hand tools: sharp tools and the high speed grinding and polishing equipment, hand instruments, such as wax spatulas and wax carvers.

A Bunsen burner is a laboratory device designed to heat substances for various experiments. Although many laboratories have switched over to electric hot plates, which have less potential flammability and produce more adjustable clean heat, Bunsen burners are still widely used.

Wax carvers are the tools combining a cutting surface of 11/8" and a finely knurled handle for precise work. Each stainless steel piece features single cuts for quick but smooth filing. Because they are single cut, the filing heads will not clog or rust. Ergonomic shapes give the user the ability to get into tight places, at the correct angles for nooks and corners.

Picks originally used as dental explorers, picks are excellent for a variety of uses, including scribing, positioning, probing, etc. All are fine stainless steel with knurled handles.

Wax spatulas which are mostly steel and double ended, are used in various carving, mixing, applying, spreading and smoothing wax. They have two shaped heads on each end. They are great to make designs, to smooth, or to use with wax lathes for making rings.

Duplicating machine is used for melting and mixing agar in prosthetic dentistry and duplicating molds.

Wet model trimmer is necessary dental laboratory equipment for trimming plaster in dental laboratory.

Grinding equipment is for polishing and grinding all kinds of metals in dental laboratories.

Dental oven is used for dental sintering.

Some dental technicians have computer-aided milling equipment to assist them with creating artificial teeth.

In order to work as a dental lab technician, it is necessary to learn how to correctly work with all of the types of dental lab equipment. Specialized training is a must because most of the equipment is specific to the dental industry.
