Evaluators’ Comments

  • “This is a 10 of 10. The best we’ve tried.”
  • “Very thin, so it marks only where the contact points are. It does not tear easily.”
  • “It is a necessary product in all offices.”
  • “The plastic form makes handling it much easier than loose strips.”
  • “The markings are very distinct and easy to read. Point contacts are the clearest I’ve ever seen with any brand of articulating medium.
  • “For occlusal equilibrations and adjustments of dental orthotics, I liked it a lot and will continue to use it.”

Description

TrollFoil is a super-thin, double-sided articulating foil designed to provide precise and consistent occlusal markings on wet, dry, and highly polished surfaces. The 8-micron foil is pre-mounted in a semi-rigid frame that keeps it flat and taut, allowing convenient one-handed placement without forceps while preventing ink from transferring to the clinician’s fingers. A removable protective strip supports clean handling, and the thin design is suitable for challenging clinical situations, including limited opening, smooth implant surfaces, gag-sensitive patients, wand metal or nonmetal restorations.

Clinical Tips from Evaluators

  • Dry the tooth surfaces before use to improve the clarity of the markings.
  • Use blue foil for centric occlusion and red foil for excursive movements to help identify interferences.
  • Have the patient bite firmly, then gently pull the foil through the contact to enhance the markings. 
  • Make sure the patient’s teeth are biting only on the marking paper and not on the frame holding it together.
