TECHNICAL NOTES
When repolishing and adjusting chairside,use a low speed carbide bur (Brassler, Fluted 12/30) and then a composite polishing disc or point at low speed. Then final polish, intra-orally, with Prisma gloss or Prisma Ultra gloss by Caulk in a turbo cup. In the lab we use Fuji polishing paste from GC America (not to be used intraorally).
When repairing and adding-to chairside, porcelain Silane Primer and unfilled bonding liquid must always be used to attach light-cured composite to belleGlass. Roughen the area to be added to with a medium diamond bur. Then rinse and dry well. Apply Silane on dry surface and follow manufacturer recommended instructions for use. Apply unfilled bonding agent to area and light cure. Then apply a light cured composite to desired contour and light cure for 1 minute. Then finish per repolishing instructions above.

INDICATIONS / CONTRAINDICATIONS
SINFONY
Sinfony is indicated for inlays, onlays, veneers and full coverage crowns. When used with fiber reinforcement, Sinfony is also indicated for Maryland bridges, inlay or onlay bridges and full coverage bridges reaching a maximum span of 15 mm.
Sinfony should not be used for patients who brux or clench their teeth. Sinfony should not be used for cases that have inadequate reduction or do not meet the preparation requirements. Sinfony should not be used for cases that have a span longer than 15 mm from abutment to abutment.
COMPOSITE and BELLEGLASS
Composite can be used for full crowns, veneers, inlays and onlays. It is recommended to be used in occlusion with itself, natural tooth structure, composites and resin denture teeth. Connect veneered with belleGlass (belleGlass/Connect) is used for metal-free bridges of up to 4 units (inlay, onlay, full coverage, or Maryland bridge abutments), full crowns, inlays and onlays.
Composite is contra-indicated when the opposing dentition is a conventional (which is very coarse) ceramic crown, bridge or a porcelain denture tooth. belleGlass/Connect should not be used when there is not enough clearance (minimum 1.5 mm),and the span of the bridge exceeds 22 mm. belleGlass/Connect should not be used on patients with malfunctional occlusion, such as bruxers or clenchers. belleGlass/Connect should not be used when the abutments have beveled or feather edge
margin preparations.

PREPARATION
SINFONY
Anterior Crowns require 1 - 1.5 mm lingual reduction with a chamfer margin.
Maryland bridges require 1.5 mm lingual clearance, 2 mm proximal boxes on the abutment teeth and 1 - 1.5 mm rounded shoulder reduction with a supra-gingival margin.
Veneers require 1 mm facial reduction with a chamfer margin.
Posterior crowns or full coverage bridges require a reduction of 1 - 1.5 mm width at the gingival floor, 1.5 - 2 mm isthmus width and 1.5 mm depth.
Inlay bridges require a butt joint margin and 1-1.5mm width at the gingival floor, 1.5 - 2 mm isthmus width, and 1.5 mm depth.
COMPOSITE and BELLEGLASS
Preparation requirements for Premise Indirect and belleGlass/Connect restorations are similar to that of all-ceramic restorations; requiring rounded internal line angles, shoulder margins of at least 1 mm and an occlusal clearance of at least 1.5 - 2 mm.

CEMENTATION
SINFONY
All Sinfony restorations should be cemented using Silane and a dual-cure resin cement that matches the shade of the restoration.
Variolink II
Dual-Cement
Nexus
COMPOSITE and BELLEGLASS
All composite or belleGlass/Connect restorations should be cemented using Silane and a dual-cure resin cement that matches the shade of the restoration. Recommended cements are VarioLink II, Dual-Cement and Nexus.
Remove temporary and clean preparation with pumice and try-in restoration. Adjust if necessary. Then acid etch enamel and use current enamel/dentin bonding system. Sandblast internal surface of restoration and apply silane per manufacturer's instructions. Mix dual cure cement and apply to internal surface of restoration evenly. Seat restoration and hold down with instrument while the doctor or assistant uses floss to remove excess cement to reduce finishing time. Then light-cure for 1 minute per surface and finish excess per finishing techniques listed above.
