Product Description
Angelus Interlig - Braided glass fiber
Braided glass fiber impregnated with light-cured composite resin used in Splinting in periodontics, Splinting of traumatized teeth, Fabrication of adhesive direct temporary prostheses. Reinforcement of large restorations.
Interlig is a reinforced composite material with glass fibers, for use in the clinic, with a range of applications: temporary periodontal or orthodontic immobilization, for emergency treatment of teeth lost due to periodontitis, pre-surgical splinting, for the reinforcement structure of fixed prosthesis, either mediate or immediate, for making intraradicular cores, for space retaining in primary or permanent
dentition, for reinforcement of acrylic structure (provisional, total prostheses), for reinforcement of large restorations of composite resin. Interlig glass fibers are intertwined, which facilitates the use by the dentist. Their maleability is superior than that of the polyethylene fibbers.
Interlig can be cut with any cutting instrument and does not require special equipment. The glass fibers are impregnated with light-cured composite resin, and for this reason, no other type of adhesive or resin is needed to impregnate them.
Pre-impregnation facilitates handling and improves bonding between the glass fibers and the composite resin. The fibers are pre-impregnated with an unfilled resin matrix, using an immersion process with controlled time and temperature, in order to guarantee complete absorption and, consequently, guaranteeing the better mechanical performance of the product.
Aesthetics
- The translucency of Interlig fibers and of the resin matrix provides high aesthetic resolution.
Strength
- The structural composition of Interlig® fibers and their preparation for dental use ensure their high resistance to bending, ensuring their indication for a wide range of clinical situations
Versatility of use
- Interlig width can be adapted for use in various clinical activities.
Excellent bonding to composite resin
- The pretreatment of the Interlig fibers allows for perfect adhesion to resins in use in the clinic.
Convenience of use
- does not require special tools for cutting and comes already impregnated with resin.
Reversible and minimally invasive technique
- due to its adhesion to the adhesive and resin systems, work done with Interlig does not require invasion of the tooth structure.
Timesaving
- work with Interlig can be performed directly in the mouth, allowing for its completion in one session.
Low cost
- Compared to traditional techniques, using Interlig® allows you to perform more attractive and durable work, with a better cost-benefit ratio
Indications
- Periodontal splints
- Splinting of traumatized teeth
- Fabrication of direct and indirect adhesive
- temporary prostheses
Instructions:
A. PERIODONTAL SPLINT
a. Pre-op;
b. Isolate with rubber dam (ideally) and place wedges interproximally to help controlling the flow of resin in these areas.
c. With a pencil, delineate the area for cutting a groove.
d. Make a 0.8 mm deep x 2.0 mm wide groove.
e. Etch with 37% phosphoric acid for 30 seconds; wash and dry (areas of exposed dentin should not be desiccated).
f. Apply the adhesive FUSION-DURALINK® system (same procedures used for direct composite resin restorations).
g. Light-cure all segments of the splint site for 20 seconds each.
h. Fill half of the groove with a hybrid or microhybrid composite resin (microfil resins should not be used in splinting);
i. Cut a section of INTERLIG® slightly shorter than the length of the groove; position INTERLIG® in the groove and press it towards the composite resin.
j. Gently pressing, light-cure each segment of the splint for 20 seconds; curing of non-pressed areas should be avoided by covering them with an aluminum foil.
k. Apply a second layer of composite resin to cover the groove totally; the resin must also be placed slightly beyond the limits of the groove.
l. Light-cure each segment for 40 seconds.
m. Remove the excess of resin, check the occlusion, and adjust it if necessary; proceed with finishing and polishing.
n. Apply a final layer of fluid resin (adhesive) to fill any irregularity or superficial bubbles and voids; light-cure all segments for 20 seconds each.
o. Final result.
B. DIRECT FIXED BRIDGE
a. Pre-op.
b. Mark the site where the root will be cut after extraction.
c. Area after tooth removal.
d. Cut the root 1 to 2 mm apically to the mark considering soft tissue shrinkage during the healing process; shaping and polishing of the apical end of the tooth should produce a pontic-like, smooth and ovate design.
e. Open the canal through the root, remove all pulpal tissue and fill the canal with composite resin (phosphoric acid and an adhesive system must be used).
f. Isolate with rubber dam and cut a groove (0.8 mm deep x 2.0 mm wide) on the abutment teeth and on the extracted tooth.
g. Fix the extracted tooth on the desired site with a small amount of composite resin placed facially; do not acid-etch now because this composite resin will be removed later; light-cure the resin.
h. Acid-etch (37% phosphoric acid) for 30 seconds; wash and dry without desiccating any exposed dentin.
i. Apply the adhesive FUSION-DURALINK® system, wait for 20 seconds, and remove excess of bonding agent with a light stream of air; light-cure each segment for 20 seconds.
j. Apply a layer of a hybrid or microhybrid composite resin filling half of the groove.
k. Measure and cut INTERLIG® with a scalpel or scissors in a slightly shorter size than the groove to facilitate insertion.
l. Place INTERLIG® in the groove, press it, and light-cure each segment for 40 seconds; curing of non-pressed areas should be avoided by covering them with an aluminum foil.
m. Apply a new layer of composite resin to cover INTERLIG® completely and fill the groove; the resin must be placed a little beyond the limits of the groove; light-cure for 40 seconds.
n. Remove excess of resin, check the occlusion, and adjust it if necessary; proceed with finishing and polishing; apply a layer of fluid resin (adhesive) to fill any irregularity or superficial bubbles and voids; light-cure all segments for 20 seconds each.
o. Final result.
C. INDIRECT FIXED BRIDGE (FABRICATED ON A WORKING CAST)
a. In the mouth, prepare a groove (0.8 mm deep x 2.0 mm wide) on the abutment teeth and take the impression.
b. On the working cast, paint the groove and its adjacent areas with a thin layer of a release agent.
c. To be used as a pontic, select an acrylic resin denture tooth or make a tooth with porcelain or composite resin.
d. Apply the adhesive FUSION-DURALINK® system and light-cure for 20 seconds.
e. Insert a layer of light-cured hybrid or microhybrid composite resin to fill half of the groove; do not cure.
f. Measure and cut INTERLIG® with a scalpel or scissors in a slightly shorter size than the groove to facilitate insertion; place INTERLIG® in the groove.
g. Press it and light-cure each segment for 40 seconds; curing of non-pressed areas should be avoided by covering them with an aluminum foil.
h. Apply a new layer of composite resin to cover INTERLIG® completely and fill the groove; light-cure for 40 seconds.
i. With carbide burs or discs, trim the stone to release the bridge; the restoration should not be forced out of the working cast to avoid the risk of fracturing the connections; proceed with the final adjustments and polishing.
j. Bridge ready; it must be cemented with an adhesive technique (adhesive system and a composite resin or resin cement)
Storage:
