GC Tempron

Direction 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).
