Directions For Use

TECHNIQUE FOR USE

• PERIODONTAL SPLINT
  a. Pre-op;
  
• Isolate with 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;
  L Cutting a groove is an optional procedure which 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 microhybrid 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;
  
• Final result

  Interlig must be totally covered by the restorative resin because it
  absorbs water. In case of exposition to humidity, properties will be
  altered.
  Interlig is impregnated with light-cured resin and should be protected
  from 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 resin.
  • Structures reinforced with INTERLIG® should not create occlusal

  interferences; always check carefully.
  • Harmful habits (grinding, clenching, biting objects) should be
  corrected before indicating restorations reinforced with
  INTERLIG®.”
