Fixed Restorations
IPS e.max®

The lithium disilicate blocks of IPS e.max® are composed of a unique crystalline, monolithic structure, giving this material its unbelievable esthetics, strength and durability. At Treasure Dental Studio, we press our e.max, ensuring optimum flexural strength of 400 MPa and outstanding marginal fit. With less fracturing and fewer chairside adjustments, IPS e.max Press is ideal for thin veneers and anterior bridges, and is a cost- and time-saving option for your practice.

Indications

IPS e.max® should not be used on patients with malfunctional occlusion such as bruxers or clenchers. IPS e.max® should not be used as abutments for cast partials. IPS e.max® should not be used in situations when preparation requirements cannot be achieved. IPS e.max® is not indicated for Maryland-type bridges.

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.

Cementation

For greatest strength, and where preparation allows for dry field (supra-gingiva margins), it is recommended to use adhesive bonding, such as VarioLink II (Ivoclar Vivadent) or similar dual cure materials (Insure, Cosmedent; Nexus, Kerr; Choice, Bisco, Inc.; Lute-It, Pentron).

For areas subgingival, or when a dry field cannot be achieved, Ivoclar Vivadent recommends a hybrid glass ionomer cement system with less than 0.5 percent expansion. (NOTE: Resin-reinforced glass ionomers (Advance, Vitremer) are not indicated for any all-ceramic restoration.)

Some recommended resin cements:

  • Vivaglass (Ivoclar Vivadent)
  • GC Fuji (GC America)
  • Ketec Cem (3M ESPE)
  • Panavia F (J. Morita)
  • C&B Metabond
  • Variolink (Ivoclar Vivadent)

Tech Notes

If adjustment is required on the ceramic, ALWAYS CEMENT OR BOND INTO PLACE BEFORE PROCEEDING, then use a fine diamond with water to keep the crown cool. To contour the crown, polish with a porcelain polishing wheel ( Brassler, Shofu and Vident) and diamond polishing paste.

Caution: Do NOT attempt to fire porcelain. IPS e.max® ceramic requires specific stains and glaze, as well as precisely calibrated ovens at specific temperatures and vacuum settings.For best results, return crown for re-glaze firing to lab.

BruxZir®

BruxZir® is the perfect metal-free option for posterior restorations. With strength up to 1200 MPa, this completely monolithic crown will not chip nor break. It’s indicated for second molars, even on bruxers. BruxZir is backed by a five-year warranty against breakage.

Indications

Indicated for posterior crowns, bridges, inlays and onlays. An esthetic solution for bruxers and grinders when PFM metal occlusal/lingual or full-cast restorations are not desired or when patient lacks the preparation space for a PFM or has broken a PFM in the past. Zirconia can also be used for anterior teeth with a facial veneer of porcelain for improved esthetics

Preparation

Shoulder preparation not needed, feather edge is okay. It is a conservative preparation similar to full-cast gold, so any preparation with at least 0.5 mm of occlusal space is accepted.

Minimum occlusal reduction of 0.5 mm; 1 mm is ideal.

Adjustments and polishing:

Adjust BruxZir® 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 BruxZir® restorations with the porcelain polishing system of your choice.

Cementation

  • Resin Ionomer cement (RelyX or RelyX Unicem, 3M ESPE)
  • Maxcem Elite (Kerr)
  • Panavia F 2.0 (Kuraray) -ideal for short, tapered preparations
  • Glass ionomer cement (GC Fuji, GC America)

Tech Notes

Solid zirconia requires a cast gold type preparation.

Anteriors may have a facial veneer of porcelain but the occlusion will remain in 100 percent zirconia. Final Zirconia restorations are glazed to a smooth surface to reduce plaque accumulation.

BruxZir® Anterior

The strength and consistency of BruxZir® full-contour zirconia now has the esthetics doctors and patients demand for incisal restorations. Its translucency and natural coloration – it’s stainable to all 16 VITA® shades – make it a natural alternative to IPS e.max® restorations, while delivering average fractural strengths of 650 MPa.

Indications

Indicated for posterior crowns, bridges, inlays and onlays. An esthetic solution for bruxers and grinders when PFM metal occlusal/lingual or full-cast restorations are not desired or when patient lacks the preparation space for a PFM or has broken a PFM in the past.

Lava

The Lava™ All-Ceramic system from 3M™ ESPE™ provides cutting-edge CAD/CAM precision and esthetics for all ceramic crowns and bridges on a zirconium oxide base. Natural-looking esthetics, incredible strength and biocompatibility of Lava restorations only scratch the surface of itspotential. Lava’s CAD/CAM origins enable less tooth structure to be removed, and conventional cementation techniques are used. When you need to deliver strong, precise and beautiful restorations for your patients, look no further than the Lava All-Ceramic system, available at Treasure Dental Studio.

Indications

Indicated for single-unit crowns and 8-unit bridges with a maximum span length of 55 mm. Ideal for inlay bridges, wing-type bridges and implant copings. Cantilever bridges with one pontic can be fabricated if the bridge has a double abutment.

Contraindications

Lava is not indicated when there is less than 1.5 mm of occlusal space, feather-edge margins or bridge length is greater than 55 mm.

Preparation

Anterior full-coverage crowns require a Chamfer with 1.5- 2.0 mm facial reduction, 1 – 1.5 mm lingual contact clearance, 1.5 – 2 mm incisal reduction, 1 – 1.5 mm reduction at the gingival margin with rounded internal line angles; or a Shoulder with 1 mm lingual reduction, 2 mm incisal reduction, 1.5 mm labial reduction, 1 mm 360 degree rounded shoulder.

Posterior full-coverage crowns require a Chamfer margin with 1.5 – 2 mm occlusal reduction, 1.5 mm buccal and lingual reduction with rounded internal line angles; or a Shoulder with 1.5 – 2 mm occlusal reduction, 1.5 mm buccal and lingual reduction and 1 – 1.5 mm gingival margin reduction with rounded internal line angles.

Chamfer Margins – Correct preparation of the chamfer margins interproximally allows the appropriate bulk of porcelain. In addition, Lava has a digital wax up to bulk up the zirconia substructure when extra support for the ceramic is needed.

A Slice Preparation – This technique enables the ceramist to close the space and avoid unnatural lingual contours

Cementation

  • Panavia 21
  • Glass Ionomer Cement (Fuji GC)
  • Resin Ionomer Cement (RelyX by 3M ESPE)

Tech Notes

It is not suggested to adjust the internal aspect of the zirconia. If an adjustment is required on the veneering ceramic, use a fine diamond at low-speed with water and air to keep the ceramic from fracturing. To polish the ceramic, use a porcelain polishing system or pink rubber wheel and diamond polishing paste (Brasseler, Shofu, and Vident).

NobelProcera®

NobelProcera® is one of the most convenient and patient-satisfying products to implement into your practice. It uses traditional methods to cement the final restoration and is highly esthetic and biocompatible. Procera has alumina and zirconia options and is a wonderful choice for many restorations. Using the Forte® scanner, your patients get a restoration made with CAD/CAM technology, ensuring precise-fitting crowns that are durable, biocompatible and incredibly esthetic.

Captek™

A highly-advanced metallurgic technology, Captek™ employs capillary action to produce precise, exceptional fitting copings for all conventional crowns and bridges. Captek’s esthetics are unsurpassed, but its internally reinforced gold gives it superior strength and first-rate bonding capabilities. With excellent biocompatibility and thinner castings for less tooth reduction, your patients will quickly become a fan of Captek.

Indications

Captek can be used for all single unit crowns and bridges with up to 2 pontics. Captek can be used when reduction of the tooth may be limited. Captek can be used when periodontal health is a concern and when biocompatibility is a concern.

Contraindications

Captek should not be used when a tooth preparation is not built back up to preparation form or there is over 3 millimeters of clearance. Captek should not be used when adapting to a future or existing partial, or when a metal occlusal is prescribed.

Preparation

The ideal preparation for PFMs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation of 1.25 mm is required.

Anterior: 2 mm incisal reduction, 1.5 mm middle third reduction, ensuring preparation is cut into three planes and that labial and lingual walls are convergent.

Posterior: 2 mm occlusal reduction; 1.5 mm middle third reduction; 1.25 mm gingival reduction on the buccal; buccal and lingual walls must be convergent. Feather-edge margin preparations are indicated for full-cast restorations.

Cementation

  • Panavia 21 (Must be tinplated)
  • Glass ionomer cement (GC Fuji, GC America)
  • Zinc Phosphate
  • Polycarboxylate
  • Resin Ionomer cement (RelyX, 3M ESPE)

Tech Notes

We use capillary attraction forces to create the Captek copings. It is the only way to combine the hard, thermally stable particles of platinum/palladium and the resilient, vibration absorbing, esthetic enhancing particles of the high purity gold without sacrificing strength. If we were to take gold, platinum and palladium in similar amounts and melt them together similar to traditional casting methods we would have a soft, weak, silver unstable coping. Just like the way the water and sponge exist, the gold and platinum/palladium exist. We have created an “alloy composite”. Captek is strong (in a sense reinforced), high gold and high temperature stable for accurate margins during porcelain firings.

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).

PFM

PFM crowns offer the proper equilibrium between the strength and durability of a full-cast crown and the naturally esthetic properties of an all-ceramic. We fabricate each PFM according to your exact details, creating a substructure with incredible fit and function, then top it with a lifelike porcelain overlay.

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.

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.
