4. Composite: A flowable composite (e.g. PermaFlo
adaptive initial layer. Use a paste composite for the last 2-3mm layer. For
surfaces subject to minimal wear such as Class V's, a flowable composite may
be used as a final surface. Follow composite manufacturer's directions for use.
Section II. Metal
1. Prepare Metal Surface: Micro-abrade metal surface.
PLEASE NOTE: Bond strength to metal is determined by metal alloy and a
superior surface preparation technique.
2. Clean/Etch: Metal surface should be cleaned with Ultra-Etch for 10 seconds
followed by a 5 second rinse with firm air/water spray. Dry thoroughly.
3. Bond: Apply a puddle coat of Peak
with an Inspiral
Brush tip. Using air syringe, gently thin adhesive to a uniform
®
glossy coat and continue drying for 10 seconds. Avoid pooling of adhesive.
Surface will look glossy. Light cure for 20 seconds using a standard light with an
output less than 1000mW. Light cure 10 seconds using a light with an output
greater than 1000mW.
4. Restore: Composite resin of choice may now be placed following manufacturer's
directions for use. Begin with 0.5 – 1.5mm initial layer. Cure, then continue
building in 2-3mm incremental layers.
PLEASE NOTE: When metal opaquing or opaquing of dark dentin is necessary,
use a thin layer (.2-.5mm) of PermaFlo
placement of composite resin.
Section III. Composite Repair
1. Prepare Surface: Remove weakened portions of existing composite. Roughen
surface with diamond bur and clean composite with etch (using micro-abrasion
provides superior results).
2. Etch: Etch the dentin/enamel adjacent to restoration and all prepared
composite surfaces for 10 seconds. Rinse thoroughly for 5 seconds using firm
air/water spray and leave damp.
