DIRECTIONS FOR USE

DIRECT METHOD (in the patient’s mouth)

A. Temporary Crowns & Bridges

1. Transfer of putty stick to the storage case Transfer putty stick from the aluminum foil pack into the storage case provided in the Introductory Set.
   Note:

1. When putty stick is transferred to the storage case or is dispensed, handle with care in order to prevent contamination.
2. If the storage case is used repeatedly, fine abrasion fragments may be produced from the lid because of the structure of the case. When paste is replaced, make sure that the inside of the case is clean. If it is dirty, clean with cotton moistened with alcohol.

2. Dispensing material Dispense the required amount of material using the spatula. Adjust the shape of paste with gloved fingers to allow easy placement onto the abutment. To soften the material, lightly knead several times with the fingers.
   Note:

1. Do not warm up before use. The material will become sticky, making it much more difficult to handle.
2. Do not knead excessively, or the material will become sticky. 3) After dispensing, immediately close the storage case to protect the material from light.

3. Preparations for pressing material onto the abutment Make preparations in such a way as to ensure that the mass of material fits into the space between the abutment and the adjacent tooth. It is effective to shape the material in advance so that it goes into the space easily (Picture A-3a), or to put another paste in the space before the mass is pressed onto the abutment (Picture A-3b).
   Note:
   If any undercuts are present on the abutment, block out with wax before placing material.

4. Pressing material onto the abutment Press the material onto the abutment and roughly contour with the fingers or spatula.
   Note:
   Apply COCOA BUTTER or Vaseline to the fingers or spatula to help shape the material more easily and to make the surfaces glossier. For additional application of material, temporarily light cure and remove the coated surface using a laboratory carbide bur, etc.

5. Shaping material: Step 1
   Let the patient bite softly to register the occlusal surface and adjust occlusion. Also adjust and contour the margin of the buccal surface.

6. Shaping material: Step 2
   Adjust the margin again as necessary, and contour the proximal and lingual surfaces. Using an appropriate instrument, remove any excess material, particularly from interproximal spaces.
   Note:

1. If shaping the material takes a long time, it may become sticky. In this case, apply COCOA BUTTER or Vaseline to the fingers or instrument. In cases where additional application of material is needed, temporarily light cure and remove the coated surface using a laboratory carbide bur.
2. Any material remaining after shaping should not be returned for storage because it has been exposed to ambient light. Dispose of it according to normal practice.

7. Temporary light curing Temporarily light cure the restoration in the patient’s mouth in order to prevent possible deformation during removal from the mouth. Light cure all surfaces of the crown or unit for a combined total of 10 seconds with Halogen/LED (> 700 mW/cm2). Note:
   1) Make sure that no excess material remains in interproximal spaces before light curing. Any material remaining will make it difficult to remove the temporary restoration from the mouth.
   2) Remove and trial fit the temporarily light cured restoration perpendicular to the abutment.

8. Final light curing Perform final polymerization outside the patient’s mouth. Light cure each of the buccal, proximal, occlusal and lingual surfaces for 20 seconds with Halogen/LED (> 700 mW/cm2). When using a tabletop fluorescent light curing unit (LABOLIGHT LV-III or equivalent), light cure for at least 3 minutes.
   Note:

1. When using a hand held type of light curing unit, be sure to light cure the internal surface of each crown or unit for the above designated time.
2. When using a hand held type of light curing unit*, the range of effective polymerization depends on the cross sectional area of the light guide. If the resin restoration is larger than that, light cure in sections for effective polymerization.
3. Too short an irradiation time will result in incomplete hardening and possible discolouration.
   Irradiation time and Depth of cure

| 1 mm| 2mm| 3mm| 4mm
---|---|---|---|---
Halogen/LED (> 700 mW/cm2)| –| –| 10 sec.| 30 sec
High power LED (more than 1200 mW/cm2)| –| 5 sec| 10 sec.| 20 sec.
LABOLIGHT LV-ill| 30 sec.| 1 min.| 3min.| 15 min.

Note: 20 sec. with Halogen light – 3.5 mm

9. Correction of contour, finishing and polishing Correct the temporary restoration using a laboratory carbide bur or silicone point. For an external addition, use REVOTEK LC. For an internal addition, use a self-curing resin (UNIFAST Trad, ALIKE), a light-cured resin (UNIFAST LC) or a flowable composite according to its instructions for use. Polish with a felt or chamois wheel to provide a glossy and beautiful appearance.
   Note:

1. It is recommended to use a laboratory carbide bur to grind the hardened restoration. When using a fine diamond bur such as GC SMOOTH CUT, or a steel bur, first remove the unpolymerized layer with a laboratory carbide bur or alcohol to prevent the diamond or steel bur from clogging.
2. Before UNIFAST Trad, Alike or UNIFAST LC is additionally poured onto the inside of the restoration, drill a hole into the occlusal or buccal surface to allow discharge of excess resin so that the temporary restoration can be properly seated

10. Completion Cement the completed temporary restoration using FREEGENOL TEMPORARY PACK or equivalent temporary cement.
11. Repair If needed, the cemented temporary restoration can be repaired in the patient’s mouth using REVOTEK LC or a self-curing resin (UNIFAST Trad, ALIKE), a light-cured resin (UNIFAST LC) or a flowable composite according to its instructions for use.
    a. Remove a layer of the surface to be repaired using a laboratory carbide bur. For optimal results, apply a resin bonding agent to the area and dry with an air syringe.
    b. Place material over the area, shape, cure and polish.

B. Temporary Inlays & Onlays

1. Transfer of putty stick to the storage case Follow instructions as described under A1 above.
2. Dispensing material Follow instructions as described under A2 above.
3. Preparations for applying material into the inlay cavity Block out undercuts with a (VLC) glass ionomer cement. Apply COCOA BUTTER or Vaseline to all surfaces of the preparation, including the (VLC) glass ionomers base / liner.
4. Pressing material into the inlay cavity Press the material into the cavity and roughly contour with the fingers or spatula. Note: Apply COCOA BUTTER or Vaseline to the fingers or spatula to help shape the material more easily and to make the surface glossier. For additional application of material, temporarily light cure and remove the coated surface using a laboratory carbide bur, etc.
5. Shaping material : Step 1 Let the patient bite softly to register the occlusal surface and adjust occlusion.
6. Shaping material : Step 2 Adjust the margin as necessary. Using an appropriate instrument, remove any excess material.
   Note:
   1 )If shaping the material takes a long time, it may become sticky. In this case, apply COCOA BUTTER or Vaseline to the fingers or instrument. In cases where additional application of material is needed, temporarily light cure and remove the coated surface using a laboratory carbide bur.

2. Any material remaining after shaping should not be returned for storage because it has been exposed to ambient light. Dispose of it according to normal practice. 3)For ease of removal, you can insert a pin into the inlay.
