- 1 x Fiber (8.5 cm long)
Direction to Use
TECHNIQUE FOR USE -:
A.PERIODONTAL SPLINT
- Pre-op;
- Isolate with a rubber dam (ideally) and place wedges interproximally to help controlling the flow of resin in these areas;
- With a pencil, delineate the area for cutting a groove; (Cutting a groove is an optional procedure that depends on the clinical situation).
- Make a 0.8 mm deep x 2.0 mm wide groove;
- Etch with 37% phosphoric acid for 30 seconds; wash and dry (areas of exposed dentin should not be desiccated);
- Apply the adhesive FUSION-DURALINKsystem (same procedures used for direct composite resin restorations);
- Light-cure all segments of the splint site for 20 seconds each;
- Fill half of the groove with a hybrid or micro hybrid composite resin (microfil resins should not be used in splinting);
- Cut a section of INTERLIGslightly shorter than the length of the groove; position INTERLIGツョ in the groove and press it towards the composite resin;
- 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;
- 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;
- Light-cure each segment for 40 seconds;
- Remove the excess of resin, check the occlusion, and adjust it if necessary; proceed with finishing and polishing;
- 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;
B. DIRECT FIXED BRIDGE
- Pre-op;
- Mark the site where the root will be cut after the extraction;
- Area after tooth removal;
- 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;
- 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);
- Isolate with a rubber dam and cut a groove (0.8 mm deep x 2.0 mm wide) on the abutment teeth and on the extracted tooth;
- 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;
- Acid-etch (37% phosphoric acid) for 30 seconds; wash and dry without desiccating any exposed dentin;
- Apply the adhesive FUSION-DURALINK system, wait for 20 seconds, and remove the excess of bonding agent with a light stream of air; light-cure each segment for 20 seconds;
- Apply a layer of a hybrid or micro hybrid composite resin filling half of the groove;
- Measure and cut INTERLIGツョ with a scalpel or scissors in a slightly shorter size than the groove to facilitate insertion;
- Place INTERLIGin 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;
- Apply a new layer of composite resin to cover INTERLIGcompletely and fill the groove; the resin must be placed a little beyond the limits of the groove; light-cure for 40 seconds;
- Remove excess 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;
- Final result.
C. INDIRECT FIXED BRIDGE (FABRICATED ON A WORKING CAST)
- In the mouth, prepare a groove (0.8 mm deep x 0 mm wide) on the abutment teeth and take the impression;
- On the working cast, paint the groove and its adjacent areas with a thin layer of a release agent;
- To be used as a pontic, select an acrylic resin denture tooth or make a tooth with a porcelain or composite resin;
- Apply the adhesive FUSION-DURALINK system and light-cure for 20 seconds;
- Insert a layer of light-cured hybrid or micro hybrid composite resin to fill half of the groove; do not cure;
- 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;
- 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;
- Apply a new layer of composite resin to cover INTERLIG completely and fill the groove; light-cure for 40 seconds;
- 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 andpolishing;
- Bridge ready; it must be cemented with an adhesive technique (adhesive system and a composite resin or resin cement).
D. REINFORCEMENT OF TEMPORARY ACRYLIC RESIN BRIDGES
- Cut an 8 mm deep x 2.0 mm wide lingual groove on the bridge;
- Apply the adhesive FUSION-DURALINK system on the groove and light-cure for 20 seconds;
- Measure and cut INTERLIG with a scalpel or scissors in a slightly shorter size than the groove to facilitate insertion;
- Insert a layer of light-cured hybrid or micro hybrid composite resin to fill half of the groove; do not cure;
- 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;
- Apply a new layer of composite resin to cover INTERLIG completely and fill the groove; light-cure each segment for 40 seconds;
- Proceed with the final adjustments and polishing;
- Final result.
PRECAUTIONS -:
- The components of INTERLIG may beallergenic. Avoid contactwith oral tissues, skin &eyes. Use gloves, mask & eye protection. If accidental contact occurs, wash with water. If necessary, seek medical attention.
- Keep it in a dry, cool place (below 28degrees C/ 82.4degrees F), protected from light, eugenol products, and excessive heat (furnaces, sterilizers).
- Put the remaining fiber in the package immediately after use to avoid excessive exposure to environmental light.
WARNINGS -:
- INTERLIGツョmust always be covered by the composite resin; any exposed fiber should be gently removed with burs and the area corrected with a new layer of composite
- Structures reinforced with INTERLIGツョshould not create occlusal interferences; always check
- Harmful habits (grinding, clenching, biting objects) should be corrected before indicating restorations reinforced with INTERLIGツョ.
