Trollfoil

Description

Occlusal adjustment is a critical step in restorative dentistry. Any undetected, heavy occlusal contact (high point) can lead to a variety of consequences ranging from minor cracks or antagonist wear to catastrophic tooth fracture, implant failure or even TMJ breakdown.

Despite the introduction of computerized occlusal analysis devices, articulating paper remains the most common means to check occlusion. The sensitivity and reliability of the techniques applied for occlusal analysis when using articulating paper depends on its thickness, composition, ink substrate, and plastic deformation. The oral environment (saliva, humidity) also plays an important role. Another factor that affects the readings when using articulating paper is the restorative material used. Conventionally, the material used in fixed and removable prosthodontics was either metal, composite, porcelain fused to metal, veneered zirconia, or acrylic resin. The recent introduction of full-contour zirconia, either manually polished or furnace glazed, can affect the interpretation of the reading of the articulating paper.

The Swedish occlusion foil TrollFoil (Directa) is the best ally of any dentist to meet these challenges. This exact, double-sided articulation foil can be used under a wide variety of clinical situations, including wet or dry teeth, limited opening, limited vestibular space, gaggers, on restorations in any material, including highly polished surfaces such as zirconia and e.max.

TrollFoil is mounted on a rigid plastic frame that keeps it stretched and straight, enabling the operator to hold it without the help of forceps.

Research shows that the thinner the articulating paper, the more precise marks you get. Thick articulating paper generates a less uniform and larger contact area than the occlusal area marked with thin articulating foil. This is why TrollFoil measures only 8 microns. It proves especially useful when checking the occlusion on implants that have a very smooth and shiny surface.

INDICATIONS

Super thin, self-mounted and designed to mark literally on all surfaces, Trollfoil is the ultimate articulating paper in the global market.

• Can be used to register marks on wet or dry teeth,
• Can be used to register marks on metallic and zirconia restorations,
• Can be used to register marks on e.max and feldspathic porcelain.
