Inspire HS can be used for any C & B or screw-retained implant case when anterior or posterior crowns and long-span bridges are prescribed. Also it can be used as an esthetic alternative to a PFM with metal occlusion due to limited occlusal or lingual space.
When esthetic expectations are high and it is important that the restorations match surrounding natural dentition or Other existing
restorations. If bonding is necessary to retain the restoration, bond strength is weaker and less predictable than other ceramics.
Shoulder preparation not needed. A mild chamfer or a feather-edge margin is good. Imm buccal, lingual, and occlusal reduction is
ideal, but can go to .5mm in some areas when reduction is limited. Minimum occlusal reduction of 0.5 mm; 1 mm is ideal.
Adjustments and polishing: Adjust full-contour zirconia crowns and bridges using water and air spray to keep the restoration cool al
to avoid microfractures with a fine grit diamond. If using air only, use the lightest touch possible when making adjustments. A footb
shaped bur is the most effective for occlusal and lingual surfaces (on anterior teeth); a tapered bur is the ideal choice for buccal an
lingual surfaces. Polish full-contour zirconia restorations with the porcelain polishing system Of your choice.
Full-contour zirconia may be cemented using a resin reinforced glass ionomer such as RelyX Luting cement. When a greater bond is
needed do to the lack of a retentive preparation, use resin cement like RelyX Unicam or RelyX Ultimate. Before cementing all full-
contour zirconia crowns, the interior surface of the crown needs to be cleaned with Ivoclean (Ivoclar Vivadent - Amherst, NY). This is
critical in assuring maximum bond strength.
