Latest Patents

Jeff MacDonald holds a patent for a caries-resistant composite resin. This direct filling composite resin restorative features a coefficient of thermal expansion (CTE) that is similar to dentin, which is crucial for minimizing marginal percolation. The exemplary antimicrobial compound used in this resin is zinc oxide. The CTE of the composite resin restorative is maintained in the range of 12-15 ppm/°C. This low CTE is achieved through high filler loading of a trimodal distribution of low CTE filler. By ensuring that the CTE is substantially similar to that of dentin, the incidence of secondary caries is significantly decreased.
