Dentistry’s most underutilized material....Microfill By: K. William Mopper, DDS, MS

Microfill is the key ingredient for successful anterior esthetics. Why microfill? Because microfill is very translucent and transparent and simulates enamel more than any other material. Its small particle size allows dentists to achieve an unsurpassed polish and luster which will maintain its polish far longer than a hybrid or microhybrid material. The reason for this stability in appearance is due to the varying particle size in microfills. Renamel Microfill’s particle size is .04 microns compared to microhybrids which are .02 to .07 microns. This is an immense difference, as smaller particle size translates into better polishability. It is easy to see why microfill is superior for surfaces of anterior teeth.

Additionally, highly-polished microfill has a refractive and reflective index which more closely simulates enamel, leading to better lifelike and esthetic results. Microfill’s translucency allows selected tints to shine through the surface, giving a more natural appearance to the tooth structure.

Because microfill is easier to marginate, biologically the tissue response is unsurpassed by any other material, short or long term. If properly placed, finished, contoured and polished, stain at the margin and recurrent decay is seldom a problem.

Microfill used in conjunction with hybrid and opaques if necessary, will provide the strongest and most beautiful restoration possible. The Renamel Restorative System (Cosmedent, Inc.) combines the desired qualities of hybrids, opaques, tints and microfills all working together to give you esthetically, physiologically and biologically the ideal restoration.

When all of these aspects are taken into account, it is easy to understand why microfill is superior for the enamel surface. For any restoration, if you want the best polishability, the best lifelike luster of a natural tooth, the best refractive and reflective index, the best long-term maintenance over time with the least wear, and the best simulation of natural tooth structure, then microfill is king.

One microfill stands above them all. Renamel Microfill has been rated the #1 microfill by independent researchers and clinicians because it has an exceptional color range, opacity, natural fluorescence, translucency, ease of use and handling. The material can be textured and polished to provide results so natural that it is often difficult to determine which tooth is real and which tooth is Renamel.

Voted ‘Product of the Year’ by REALITY two years in a row, it is the only composite to receive this award. Renamel Microfill is part of the Renamel Restorative System, a completely integrated color-coordinated system that includes microfills, hybrids, flowables, opaquers and tints.
