Question:
Allergy to temporary crowns, bridges and cements: My sister recently found out that she is allergic to methyl methacrylate. She never feels well after the dentist's visits and this lasts for weeks.
Is there another chemical compound that can replace methyl methacrylate. Her dentist said no. She has much work yet to be done and she has similar complaints with the glue and adhesives.
Her dentist tells her to load up on allergy pills. Her allergist tells her to find another dentist who uses different materials. Please advise. Thanks... Visitor from NY
Answer:
A solution to your concern would be to use older materials such as Amalgam, Gold and Porcelain for
fillings or full cover crowns if necessary.
These could be cemented with the older cements such as Zinc Phosphate cement. These materials are proven and have been used for hundreds of years.
If your sister's symptoms do not last then the bonded or cured form may be acceptable. This would mean that the materials can be used .. but would need strict isolation during the procedure. This is similar to the mercury issue in the amalgam fillings (mercury in a free form is very harmful but in a bound form it seems to be acceptable and non-reactive).
As an alternative, there is a cement system using Glass Ionomers by Fugi company that would work with Porcelain fused to metal crowns and gold inlays.
