Smile by Design Dental Studios Zirconia CAD/CAM Frameworks

We would like to introduce you to some of the features and benefits of CAD/CAM Zirconia substructures, including strength, reliability, aesthetics, biocompatibility and affordability. 

Be sure to visit our Document Archive. There you will find technical documents that you can download and print. The documents contain detailed clinical information related to Zirconia technology and current Straumann milling materials documentation.

 

Snapshots of various 3D scans can be see here.

Straumann Cares Digital Solutions for 2012
Digital Laser Technology

The 3D laser scanner scans dies and models, acquiring jaw and die situation data. Even complex bridges with very tight interproximal spacing are easily scanned. The margin is automatically detected and defined.

With 28,000 precise scanning points per second, the etkon™ es1 scanner sets new standards for efficiency. At Smile by Design, we are scanning and design experts.

Detailed specs of all of our milling materials can be found here.

Milling Materials by Straumann
*see detailed material specs

Zerion™ (zirconium dioxide)
A top product for highly esthetic restorations from single unit to large span. An esthetic material designed to also suit patients susceptible to hypersensitivity reaction. 

Ticon™ (titanium)

Demonstrated biocompatibility for price-conscious patients. Radio-transparent, low weight, low thermal conductivity. Excellent bonding with ceramics due to reduction of alpha case layer. 

Coron™ (CoCr alloy)

Economic alternative in the non-precious metal sector on a cobalt chromium basis. Low thermal conductivity, excellent bonding to ceramics. 

Polyamide

For temporary restorations. A multi-purpose resin reinforced with short parallel fibers, whose physical properties remain unaffected by CAD/CAM milling. 

Polycon™ ae
For temporary restorations. A PMMA-based acrylate resin showing high stability and abrasion resistance. 
 
polycon™ cast
A filler-free acrylate that represents the alternative for conventional crown and bridge wax-up.

 

No Wax-up and Casting
Zirconia cores and framework without wax-up or casting simplify the entire process.
The process is listed below.

  • Model Work: We pour and trim the model.
  • 3D Scanning: We use a laser scanner to produce a 3D computer image (computer model) 
  • Computer Design: The Computer Design Stage: The zirconia crowns, bridgework or frameworks are designed in our laboratory aided by a computer and specialized software.  
  • Precision Milling: The Milling Stage: The information is sent to the milling machine to produce the zirconia restorations.
  • Sintering Stage: The Zerion blank is milled. The work is then placed into a high temperature furnace for sintering.
  • Veneering Porcelain Detail: The crown, abutment or framework is completed and detailed with finishing porcelain, either felspathic or pressed ceramic.

    Crown Prep - Zirconia Core

    Even at a thickness of .4mm zirconia cores are extremely strong and can withstand pressures up to 1300 MPa. For this reason a standard PFM preparation is all that is necessary.
    Brief crown prep details are:

    • Anatomical Prep Design.....restore tooth defects, cusps etc...this establishes a base for UNIFORM THICKNESS of zirconia.
    • Anterior/Posterior Prep: 1.6mm labial/lingual, 2mm incisal/occlusal
    • Margins: A distinct chamfer or rounded shoulder of 1mm minimum with standard 4 degree taper.
    • Bruxism contraindicates all-ceramic restorations
     

    Bridge Prep - Zirconia Core

    The tooth preparation for bridgework is similar to that for standard PFM crown. 

    • Framework crown/pontic connectors must be 9 sq. mm
    • Bruxism contraindicates all-ceramic restorations
