What is A Dental Lab Curing Unit in Dentistry?

22 Dec, 2023

The dental lab curing unit is essential in dental surgery because it is used for hardening or curing various dental materials such as composite resins, dental adhesives, sealants, and some types of cement. All dental curing materials require a specific wavelength of light to initiate a chemical reaction that turns them from a pliable state to a hardened or solid state.

What Are the Different Types of Curing Units?

Since you know the definition of the dental lab curing unit, the author will start to give a brief introduction to the types of dental lab curing unit. The dental lab curing unit can be divided into four types of light sources, including halogen, light-emitting diodes (LED), plasma arcs, and lasers.


The halogen lamp for dental chair is a traditional curing light providing a blue light between 400-500 nm so that it can cure most types of material. However, the halogen lamp for dental chair can become very hot during the working process.

●Light-Emitting Diodes (LED)

Led curing light is the most widely used dental lab curing unit in current dentistry. The LED curing light emits a blue light in a narrow wavelength range, typically around 400 to 500 nanometers, which matches the activation range for the photoinitiators present in the dental materials.

●Plasma Arcs

A plasma arc curing light is a high-intensity curing unit used in dentistry to harden or cure various dental materials. This technology was developed to provide a more powerful and rapid curing process than traditional curing lights.

Laser Curing Light

The laser curing light is a specialized type of curing unit that utilizes laser technology to cure or harden dental materials. It can emit consistent energy and intensity at any distance to achieve the complete and even curing effect.

What Are the Uses of Dental Lab Curing Unit?

Dental lab curing units are essential devices used in dental laboratories for curing or hardening various dental materials. These units play a crucial role in the fabrication of dental prosthetics and appliances. Here are their primary uses:

●Curing Prosthetic Components: Dental lab curing units are employed to cure materials used in creating prosthetic components like crowns, bridges, dentures, and implants. These materials often include resins, composites, acrylics, and certain types of ceramics.

●Polymerization of Resins: Many dental restorations, such as denture bases or temporary crowns, are made using resin materials that require proper curing to achieve the desired hardness and stability. The curing unit initiates the polymerization process that transforms these resins from a liquid or pliable state to a solid and durable form.

●Fabricating Orthodontic Appliances: In orthodontics, these units are used to cure materials for creating orthodontic appliances like retainers, aligners, and various brackets.

●Bonding and Repairing: Dental lab curing units are utilized in bonding processes to affix various components of dental appliances or to repair small cracks or damages in prosthetic devices.

●Custom Tray Fabrication: When fabricating custom trays used for impressions, these units help in curing the tray materials to the required hardness for accurately capturing dental impressions.
