GrandTEC

Even bonds and composites from the latest generation lack the adhesive strength for certain indications. This holds true, for example, when splinting teeth for temporary, primary interlocking after orthodontic or periodontic therapy. Additionally, a stable, reliable material is required as a foundation for treatment with composites in trauma therapy and space treatment. GrandTEC® by VOCO is the new, resin-impregnated glass fibre strand that is optimally suited for use in the dental adhesive technique. GrandTEC also facilitates minimally invasive reinforcement of metal-free treatments.

GrandTEC is a glass fibre strand that consists of multiple, densely packed, parallel running glass fibres impregnated with a special light-curing resin. GrandTEC® can be shaped before polymerisation, cured with conventional polymerisation devices and is compatible with all stan-dard, light-curing composites and flowables. The glass fibres coalesce with the composite used during polymerisation, wherein a flowable is used for the first layer on the glass fibre and its attachment to the tooth substance. Because GrandTEC® is already impregnated with a resin, cumbersome, time-consuming and often uneven wetting of the fibre strands with a bond by the dentist is completely avoided. Occurring chewing loads are evenly distributed in the restoration by the intensive chemical coalescence of glass fibres and composite.

This provides significant improvement in the transverse strength and leads to considerably higher fracture resistance of the restoration. The modern adhesive technique and GrandTEC® thus ideally complement each other to yield an innovative concept for stable treatments.

GrandTEC not only has impressive material properties, it also features outstanding handling. Each glass fibre is protected from light and sealed in an easily removable protective film en-cased in a blister. Each strip is 55 millimeters long and 2 millimeters wide. GrandTEC is easily shortened to the required length with fine-tip scissors. The glass fibre must remain in the pro-tective foil during shortening. The protective foil ensures problem-free handling of the im-pregnated glass fibres. It is removed directly before insertion into the patient's mouth or place-ment on the working model or impression in the laboratory. GrandTEC is extremely flexible and can be shaped into the desired form and adapted with the same instruments used in the composite-adhesive technique.

Tweezers with smooth tips facilitate positioning on the prepared teeth or dental technician model. GrandTEC reinforced restorations can be finished and polished with the same rotating instruments and polishers used with composite restorations.

GrandTEC was developed for use in orthodontics, periodontics, traumatology, conservative dentistry and prosthodontics. GrandTEC ensures stabilty when splinting teeth after orthodontic or periodontic therapy. It can additionally be used for fixing avulsed or loosened tooth as well as for fragment fixation after tooth fracture. GrandTEC also serves as reinforcement in the fabric-cation of provisional, composite-based crowns and bridges.

GrandTEC is suitable for tempo-rary treatment of a space after extraction and the replacement of a missing tooth with an artifi-cial tooth in the anterior and pre-molar areas. The glass strands can also be used for the tem-porary or semi-permanent treatment of a tooth space using an extracted, natural tooth. And in prosthodontics, GrandTEC provides temporary treatment of a space during the osseointegration after inserting an implant. Restorations achieve the required stability with ease and for the indication at hand with GrandTEC, the new glass fibre strips.
