TrollFoil Blue 4.5 Microns
Breaking new ground as the thinnest articulating foil available, TrollFoil Blue 4.5 allows for smaller occlusal contact markings and more accurate information for dentists
TrollFoil has long been known as the articulating foil dental professionals could rely on for precision. At 8 microns thin, the foil provides extremely accurate occlusal contact readings with a light tap from the patient. Clinicians can now achieve an even more precise diagnosis with the new, even thinner TrollFoil Blue 4.5.
Dr. Michael DiTolla, who graduated dental school in 1988, recalls using thick articulating paper that was like a thin piece of cardboard back then. “When I saw the ingenious design of TrollFoil for the first time, I was impressed to see the stiff spine that allows you to use it with or without an articulating paper holder.”
Neat and Functional Foil
The frame of the foil makes it so the ink doesn’t smudge on the patient's lips or the clinician's gloves and, because TrollFoil acts as a sponge that releases carbon-based color, it doesn't mark the teeth until the patient bites down. “Directa has the 8-micron thickness, and now the 4.5-micron thickness, which are 2 levels of accuracy beyond what any other company is doing, and that's certainly unique,” noted Dr. DiTolla.

Dr. DiTolla described a 2015 study that focused on articulating papers from about 12 microns thick to 200 microns. The papers all marked the same spots, but as they went from 200 microns down to 12 microns, the spot would get smaller and smaller.
“The small point on the 12-micron paper was also present in the thicker papers, but the spot got bigger as the paper got thicker, so dentists ended up removing more tooth and crown material than necessary,” explained Dr. DiTolla. “The 8 microns gives you more accuracy, and 4.5-microns even more so. The more precise the mark is, the less unnecessary tooth structure or crown material is removed from the tooth.”
The 4.5-micron foil is useful in implant cases, because unlike regular teeth with a periodontal ligament that can move and shift around, implants are fi xed in the bone and don't move, according to Dr. DiTolla. This provides better stability and more accurate readings.
TrollFoil also comes in handy when the patient is trying to isolate one spot that doesn't feel right when they bite down, which can happen if they have a few new crowns. “The 4.5-micron is helpful because, as you use thicker paper, you have to guess what the problem is by looking at too many different spots,” explained Dr. DiTolla. “But when you find it with the 4.5-micron paper, it's the right one, and you're not removing any excess tooth structure or crown material.”
TrollFoil Blue is clean, accurate, and convenient to use. “One of my other favorite features of the TrollFoil is that it marks wet really well, and that's important,” concluded Dr. DiTolla.
