Directions to Use
A. CROWNS
1. PREPARATION
- a) Fill defects in the tooth with GC CAVITON or equivalent temporary filling material.
- b) Take an impression using a heavy (i.e. less water) alginate impression material. Wrap the impression in wet gauze to prevent distortion.
- c) Prepare the tooth to be crowned.
- d) Cut V notches in the impression from gingival to buccal and lingual sides to allow escape of excess resin.
2. MIXING
- a) The standard powder/liquid ratio is 1.0 g/0.5 mL (up to the first graduation on the powder measure and the first graduation of the liquid pipette).
Note: To minimize shrinkage use as little liquid as possible.
- b) Measure the liquid into the mixing jar, and slowly add the corresponding quantity of powder. Mix for 20-30 seconds.
3. APPLICATION
- a) Pour the creamy paste into the prepared impression, and seat tightly in the mouth.
- b) After 3 minutes in the mouth remove the impression, leaving the dough like resin on the tooth.
- c) Remove the resin crown before it is fully set and dip in and out of hot water (± 50°C) several times in order to prevent shrinkage.
- d) Trim any excess using a bur and then polish.
- e) Cement the temporary crown in position using GC FREEGENOL or other appropriate temporary cement.
B. BRIDGES
1. PREPARATION
- a) Select a suitable artificial tooth and fix between the abutment teeth using a suitable wax. Check the bite.
- b) Take a full arch impression using an alginate impression material. Carefully remove the pontic and wrap the impression in wet gauze.
- c) Prepare the abutment teeth as appropriate. Subsequent procedures are carried out as described above for crowns A. 1 (a) to A. 3 (e).
