Fixed Restorations

fixed_zirganic

Zirganic™

Providing both esthetics and function desired by patients. Zirganic™ is partially stabilized with yttrium and enriched with aluminium and is manufactured using a biaxial compression method (same pressure being applied above and below) so the shrinking that occurs in sintering can be checked exactly.

Product Information

Indications Full-contour zirconia is so versatile, it can be used in almost any situation from singles, bridges with any combination of abutments and pontics, inlay bridges, Maryland type bridges and screw retained implants. Also an esthetic alternative to a PFM with metal occlusion due to limited space.

Contraindications Contraindications include: 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

Cementation Full-contour zirconia may be cemented using a resin reinforced glass ionomer such as Relyx Luting cement. When a greater bond is needed due 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 N.Y.). This is critical in assuring maximum bond strength.

Preparation Shoulder preparation not needed. A mild champfer or a feather edge margin is good. 1mm 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 and to avoid micro-fractures with a fine grit diamond. If using air only, use the lightest touch possible when making adjustments. A football-shaped bur is the most effective for occlusal and lingual surfaces (on anterior teeth); a tapered bur is the ideal choice for buccal and lingual surfaces. Polish Full-contour zirconia restorations with the porcelain polishing system of your choice.

Tech Notes Solid zirconia requires a cast gold type preparation. If adjustments are needed, use zirconia specific diamonds and rubber wheels polishing with diamond paste.

AM Dental Laboratory uses Argen gold for our full-cast restorations, ensuring high quality and endurable strength for this popular restorative option.

Product Information

Indications
Full-cast gold crowns are indicated for crowns, veneers, inlays, onlays and bridges.

Contraindications
Full-cast gold crowns are contraindicated for partials and implants.

Preparation
Inlays and onlays can also be fabricated as a full-cast restoration. Feather-edge margin preparations are indicated for full-cast restorations, but any margin preparation may be used.

Cementation
Panavia 21 (Must be tinplated if precious metal is used)
Glass ionomer cement (GC Fuji, GC America)
Zinc Phosphate Polycarboxylate Resin Ionomer cement (RelyX, 3M ESPE)

fixed_pfm

PFMs

PFMs are the tried-and-true union of strength and esthetics. At AM, we offer NP and SP PFMs.

Product Information

Indications
Our PFMs can be used for crowns and bridges (up to fourteen units). PFMs can be manufactured to non-precious, semi-precious, and yellow high noble copings and can be used in conjunction with cast partials and implants.

Contraindications
Contraindicated when the patient has a metal allergy or when the size of the tooth pulp is negligibly smaller thus compromising the tooth preparation process. It is also contraindicated when the clinical tooth crown is very short and lacks the required stability including retention that is enough to provide the space for porcelain and metal.

Preparation
The ideal preparation for PFMs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required. Feather-edge margin preparations are indicated for full-cast restorations.

Cementation
Panavia 21 – tin plated
Glass ionomer cement (GC Fuji, GC America)
Zinc Phosphate Polycarboxylate
Resin Ionomer cement (RelyX, 3M ESPE)

Tech Notes
If an adjustment is required on the ceramic, use a fine diamond with water and air to keep the crown cool. To contour the ceramic, polish with a pink rubber wheel and diamond polishing paste (Brasseler, Shofu, Vident).

fixed_emax

IPS e.max®

The monolithic structure of lithium disilicate gives IPS e.max® its strength, opalescence and translucency. These monolithic properties result in high flexural strength (360 – 400 MPa), excellent fracture resistance, stunning light-diffusion qualities, and a wide range of practice-building indications.

Product Information

Indications
IPS e.max press is indicated for full anterior or posterior crowns, veneers, inlays, onlays,as well as three-unit bridges having only one pontic with the second bicuspid as the most distal abutment.

Contraindications
Bridges which include molars, Maryland style bridges and bridges which have a short vertical height that does not allow for adequate connector height.

Cementation
IPS e.max layered – can be either cemented using a resin reinforced glass ionimer such as Relyx Luting cement. Or bonded using a resin cement, when extra strength is needed due to lack of retention on the prep, use a resin cement such as Relyx Unicem or Relyx Ultimate.

Preparation
Anterior full-coverage crowns require a chamfer or shoulder margin. A circular shoulder is prepared with rounded inner edges or a chamfer at an angle of 10-30°: the width of the shoulder/chamfer is approx. 1 mm. Facial reduction is 1.5 – 2 mm; 1 – 1.5 mm lingual contact clearance. Incisal reduction is 1.5 – 2 mm with rounded internal line angles, and an incisal edge at least 1mm wide to permit optimum milling of the incisal edge during CAD/CAM processing. Posterior full-coverage crown requires a chamfer or shoulder margin. A circular shoulder is prepared with rounded inner edges or a chamfer at an angle of 10-30°: the width of the shoulder/chamfer is approx. 1 mm. Occlusal reduction is 1.5 – 2 mm: axial reduction (buccal, lingual and interproximal) is 1.5 mm with rounded internal line angles.

Tech Notes
If adjustments are needed, use fine diamonds with water and light pressure. Always remove the crown when adjusting or bond/cement crown before adjustments are made.).
