3. Glazing (Coating and Polishing)
3-1 Coating method
a) Roughening the surface:
Roughen the resin surface using a carbide bur or sandblast (1.5 kg/cm
Dry and clean with air gun.
b) Priming:
Immediately apply a silane coupling agent (e.g. CERAMIC PRIMER II (GC)) to the resin surface and dry.
c) Coloring, Coating and Final light curing:
Apply a thin layer (<0.1mm) of Lustre Paint over the resin surface and final-cure.
To prevent contamination, wash the brush with Lustre Paint Diluting Liquid every time.
3-2 Polishing method
Use proper instruments and burs to polish and finish the prosthesis, and to confirm, remove any agent or paste for
polish and finish in proper way and see the surface has proper shine.
B. Anterior or Posterior Jacket Crown (metal free)
1. Preparation of the working model
a) Prepare the die stone in usual manner.
b) Apply DIE-HARDNER to the die stone surface.
c) Block out undercuts with wax.
d) Apply a layer of paraffin wax as die spacer as required.
e) Apply a thin layer of a resin composite separator.
2. Special pre-cure treatment
a) In case of a metal core, apply first a thin layer of OPAQUE. Light cure for 1 minute.
b) In case of a vital abutment tooth, apply first a thin layer of (LB-) Base OD and Pre-cure.
3. Build up of Crown
For following build up on the surface, see instructions BUILDING UP PROCEDURE A. (Section 2. b-e) above.
4. Glazing
See instructions BUILDING UP PROCEDURE A. (Section 3.) above.
5. Cleaning, treating restoration for bonding
Roughen the inner surface of Jacket crown using alumina sandblast (1.5 kg/cm
And then clean with air gun.
6. Cementation (Chair side)
a) Priming
Apply a thin layer of a silane coupling agent (e.g. CERAMIC PRIMER II (GC)) to bonding surface.
b) Cementation
Use a dental adhesive resin cement (e.g. G-CEM LinkForce (GC)).
C. Posterior Inlay
1. Preparation of the working model
Follow the instructions Preparation of the working model (B. Section 1. a-e) above.
2. Build up of Inlay
a) Build up (LB-) Inlay TD as a dentin color in order to retain the natural tooth color. Pre-cure.
Note: In the case of a stained tooth, it is recommended to first apply OPAQUE to the cavity floor. Light cure for
1 minute.
b) Build up (LB-) Inlay E , shape and contour. Final-cure.
c) Continue BUILDING UP PROCEDURE A. (Section 2. e) above.
3. Glazing
See instructions BUILDING UP PROCEDURE A. (Section 3.) above.
