Dental Solutions

Composites are the preferred method of dental restoration as they demonstrate outstanding corrosion and wear resistance, while maintaining a natural “tooth-like” appearance. HRI offers the following composite building blocks

• Monomers – The primary matrix within the formulation, commonly a methacrylate, that when polymerized, bind the composite together
• Adhesion Promoters – Enhance the composites ability to adhere to the surface of the tooth
• Photoinitiation Systems – Photoinitiators, coinitiators, and sensitizers used to convert light energy into chemical energy to induce polymerization

Hampford Research has been a leading supplier of dental restoration materials since its inception.  Customers worldwide rely on HRI’s expertise to produce monomers, adhesion promoters, and photoinitiators that meet or exceed the industry’s rigorous standards.

Monomers

Composite resins are most primarily composed of a dimethacrylate monomer (i.e. BDMA, Bis-GDMA) along with filler materials such as silica or glass. This unique combination of materials provides the functionality and appearance of the natural tooth.

Photoinitiators

Light cured resin composite systems require the use of a photoinitiatorin order to achieve full cure. Camphorquinone, one of the more common PI’s used in dentistry, is specially designed to initiate polymerization at wavelengths between 400-500 nm. The ability to initiate curing within the visible range is key to the safe application of resin based restoration. Dual cured resin composite containing both photo-initiators and chemical accelerators, are also commonly used, particularly in cases where there is insufficient light exposure for light only curing.

Resin Matrix Monomers/Modifiers

Most modern composite resins are light-cured photopolymers, meaning that they harden with light exposure. They can then be polished to achieve maximum aesthetic results. Composite resins experience a very small amount of shrinkage upon curing, causing the material to pull away from the walls of the cavity preparation. This makes the tooth slightly more vulnerable to microleakage and recurrent decay. Microleakage can be minimized or eliminated by incorporating matrix modifiers and binders into the formulation.
