How is Light-Cured Resin Tray Material Cured?
Light-cured resin tray material is a type of composite material that is used to fabricate custom trays used by dental professionals. These trays are used for various procedures like bleaching, desensitizing, and delivery of medicaments to different parts of the oral cavity. The tray material is also a popular choice for making temporary crowns and bridges.
The mechanism of curing light-cured resin tray material is based on the use of a light-curing unit. The light source provides a blue light that activates the photo-initiator present in the material and causes polymerization to occur.
The curing time for light-cured resin tray material is highly dependent on the thickness of the tray material, the intensity of the curing light, and the wavelength of the light. Most manufacturers recommend curing the tray material between 20-40 seconds per surface. Therefore, if the tray is double-sided, it should be cured on both sides separately, for example, 40 seconds on the upper surface, then flip the tray over and cure another 40 seconds for the lower surface.
To achieve the best curing, it is vital to understand the characteristics of the material, know the correct exposure time, and ensure the curing light is functioning appropriately. If the curing time is not enough, the material may not polymerize completely, resulting in the tray being soft and flexible and lacking the necessary rigidity for clinical use. On the other hand, over-curing the tray material can cause cracking, crazing, and poor adaptation to the dental arch.
In conclusion, proper curing of the light-cured resin tray material is critical for achieving optimal clinical performance. Thus, dental professionals must follow the manufacturer’s instructions carefully and invest in high-quality curing lights.
