VI. Directions for Use
(1) Take the disc from the packaging and confirm that the disc does not have a crack or other damage.
(2) Place the disc into the milling machine; then begin the milling process following the milling systems technical instructions.
(3) After milling, remove the restorations from the disc with a diamond bur etc.
(4) The cutting waste or dust, which is attached to the restorations, can be removed with a gentle air stream.
(5) Put the restorations into the refractory sagger tray and place them in the sintering furnace.
(6) Sinter the restorations according to the sintering schedule shown above. (III. Sintering Program).
(7) After sintering, adjust the restorations with a diamond bur as needed.
(8) Confirm that the restorations have no cracks.
(9)-1 Full Contour Zirconia:
    a) Glaze baking: Create a high shine surface by polishing, especially on the contact areas then apply the glaze on all surfaces in the usual manner.
    b) Hand polishing: Create a high shine surface on the entire restoration by polishing without using the glaze.
VII. Remarks on Handling
Caution:
1. When milling the disc, use an approved dust mask and vacuum with air filter to protect your lungs from inhaling dust.
2. When milling the disc, use safety glasses to prevent the dust from getting into your eyes. If the dust gets into your eyes, immediately rinse with copious amounts of water and consult a physician.
3. Do not use for any purposes except for restoration.
4. Do not touch the items heated by the furnace with your bare hands.
Caution in conjunction with usage:
1. Do not use the disc if there is a crack noticed after removing it from the package.
2. Dry milling is recommended. If wet milling is used, the translucency of the disc may be reduced.
3. If you find a crack in the restorations, do not use.
4. The above sintering recommendation is only a guideline; some adjustments may be required depending on each individual furnace.
5. When milling the disc, do not bring the milling bar into contact with the plastic ring to prevent detachment of the disc.
6. Cut and remove the plastic ring prior to sintering the whole disc.
Storage:
1. Store in a cool and dry place. Keep away from direct sunlight.
2. The product should be stored at 0-50℃ (32-122°F).
3. Do not remove the disc from its packaging during storage.
4. The disc is fragile, and requires care when handling.
5. The product must be used by the expiration date indicated on the package.
