- Try-in wing bridge
to verify fit and contact.
- Silicoating is available from Aurum Ceramic/Classic to maximize the
adhesive result.
- Clean abutment
teeth thoroughly with a bristle brush (either dry or with pumice powder
and water) or intraoral sandblaster (Micro Etcher) to remove plaque
and debris. Do not use a commercial prophy paste as it contains oils
that can weaken bond.
- Wash surfaces thoroughly
with an abundant amount of water and adequate evacuation for 15 to 30
seconds. Dry completely with a clean, oil free air supply for 15 seconds.
- Isolate surfaces
from mouth fluids with well-placed rubber dam or adequate cotton rolls
or sponges, and from adjacent teeth with Mylar strips.
- Use 30 to 40% acid-etch
solution or gel. Use small sponges or cotton pellets to saturate tooth
surfaces (lingual only) for 30 to 60 seconds. Use a continuous, gentle
wiping motion. Do not rub. Rinse well with water and evacuation for
30 seconds.
- Replace cotton
rolls if needed and dry surfaces thoroughly (i.e., 15 seconds).
- Apply unfilled
resin as per manufacturer's instructions if needed.
- Mix self-cure adhesive
system using same proportions as determined during esthetic try-in.
Mix paste according to powder-to-liquid ratio suggested by manufacturer
(should result in consistency of thick honey).
- Paint abutment
teeth and metal with thin layer of cement.
- Seat restoration.
While holding it in place, use a disposable brush tip to wipe away all
excess resin at the margins and interproximally around the pontic sections.
Hold until cement is set. Light cure the periphery if the cement is
dual-cured.
- Verify occlusion.
Finish with disks or diamonds (do not overheat). Use composite carbide
finishing burs for final finishing. Polish with microfill composite
with abrasive strips and disks.
- Instruct patient
