3.1.2 Shade selection with VITA
®
classical shade guide and i-shade label
1. Select the VITA
®
classical reference tooth, the central part of which best matches the area of the
tooth to be restored.
2. Use the i-shade label (see table below) to identify the matching Ceram.x Spectra™ ST uni-
versal CLOUD shade, and appropriate Ceram.x Spectra™ ST Effect shade(s) if enhanced
esthetic effects are desired.
3.2 Cavity preparation
1. Clean the tooth surface with a fluoride free prophylaxis paste (e.g. Nupro
®
prophylaxis paste).
2. Prepare cavity (unless not necessary, e.g. cervical lesion).
3. Use adequate isolation such as rubber dam.
4. Rinse surface with water spray and carefully remove rinsing water. Do not desiccate the tooth
structure.
3.2.1 Matrix placement and wedging (Class II restorations)
1. Place a matrix (e.g. AutoMatrix
®
or Palodent
®
Matrix System) and wedge. Burnishing of the matrix
band will improve contact and contour. Pre-wedging or BiTine
®
ring placement is recommended.
3.3 Pulp protection, tooth conditioning/dentin pre-treatment, adhesive application
Refer to adhesive manufacturer’s Directions for Use for pulp protection, tooth conditioning and/or
adhesive application. Once the surfaces have been properly treated, they must be kept uncontami-
nated. Proceed immediately to placement of the material.
3.4 Application
Apply material in increments immediately after the application of the adhesive. The material is
designed to be cured in increments up to a 2 mm depth/thickness.
Using Compules
®
Tips
1. Insert Compules
®
Tip into the notched opening of the Compules
®
Tips Gun. Be certain that the
collar on the Compules
®
Tip is inserted first.
2. Remove the colored cap from the Compules
®
Tip. The Compules
®
Tip may be rotated 360° to
gain the proper angle of entrance into the cavity or to the mixing pad.
DO NOT USE EXCESSIVE FORCE.
Indirect use: Dispense the necessary amount of material onto a mixing pad and protect against
light. Apply material into the cavity with a plastic instrument.
