Searching for “night guard allergy” online now yields more than 375,000 results from Google. This high hit rate shows the urgency of the topic in current discourse and should prompt dentists and dental technicians alike to take a closer look at the fabrication of occlusal splints for allergy patients.
Monomers and peroxides are considered potential allergens, and both substances are found in many acrylics used for making bite splints. Other substances and ingredients can be used to make the splint easier to handle or give it greater clarity, but they could also lead to a higher potential for allergic reaction. At the same time, the number of patients with hypersensitivity to dental resins is constantly increasing; because of that, dentistry has had to search for occlusal splints that are free of irritants and can be integrated effectively and efficiently into everyday laboratory and practice life.
The light-cured primosplint material from Primotec has been specially developed with the least possible potential for allergic reaction, and the market has not confirmed a single case of incompatibility, allergy, or undesirable side effects for 15 years now. In addition, primosplint is an easy-to-handle, pre-fabricated rod that is applied directly on the master model. It is precise, without clinically relevant polymerization shrinkage, tasteless, and fully autoclavable. Primotec even offers an info sheet titled "Advice for Allergy Patients," available at www.primotecusa.com. It lists a large number of regularly requested irritants that are not contained in primosplint, thus making this highly biocompatible splint material suitable for allergy patients.
