Angelus Interlig Single Patient Strip

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-DURALINK system (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 INTERLIG slightly shorter than the length of the groove; position INTERLIG® 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® 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; 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 and polishing;
• 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 be allergenic. Avoid contact with 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 28°C/ 82.4°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®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®should not create occlusal interferences; always check
• Harmful habits (grinding, clenching, biting objects) should be corrected before indicating restorations reinforced with INTERLIG®.
