CAD/CAM

Full Arch Milled in Zirconia

Digitisation of dentistry is happening now and the changes are spectacular. Advancements in technology have brought a wave of digital solutions that we can provide for the progressive restorative dentist.

We at McDowell + Service continually place ourselves at the leading edge of technology utilising the highly commendable 3shape scanners and their software CAD systems resulting in highly accurate fitting, highly accurate detailed restorations in a multitude of high quality materials.

All-ceramic restorations have been known for their durability and aesthetics, but not for their economy – until now. Never have all-ceramics been this convenient or affordable. We offer CAD/CAM systems that can help you create all-ceramic restorations, from the initial design to actual milling using our very own in-house milling centre.

An ever increasing number of dental practitioners are looking at the latest intra oral scanners to incorporate into their daily practice.

We at McDowell + Service are able to accept and process your digital impressions so providing you and your practice to increase productivity, efficiency, provide more indications and materials and create high quality prostheses, while at the same time dramatically increasing the level of surgery-laboratory communication at the touch of a button.

McDowell and Service Dental Laboratory is TRIOS ready.

  • Chameleon® Layered Zirconia Restorations

    Chameleon® Layered Zirconia restorations, including crowns, bridges, veneers, inlays and onlays, have been developed with aesthetics, reliability and biocompatibility in mind.
    Chameleon® restorations are metal-free and highly translucent, giving a more natural appearance than metal bonded to porcelain restorations, which can produce a dark line at the gumline.
    Because Chameleon® restorations are made from zirconia, a highly biocompatible material which has been used in medical treatments for many years; they can be placed next to tissue without any gum reaction or irritation.
    Chameleon® Layered Zirconia restorations are amongst the strongest and most durable in dentistry, with a flexural strength of over 1200 MPa. These restorations are designed and milled using modern CAD/CAM technology, then skilfully hand finished by Terec’s dental technicians.
    Unrivalled in natural beauty and fit.

  • Chameleon Fortress Zi

    Chameleon Fortress has unparalled flexural strength. It is an all-ceramic alternative designed specifically to meet posterior high load demands. Fortress Zi is a Monolithic, solid medical grade Zirconia for crowns, bridges or inlays without the porcelain overlay. They are hard sintered and virtually unbreakable with excellent long-term durability ideal for bruxers and grinders.

  • Chameleon® Implants

    Chameleon® Zirconia custom abutments offer the best aesthetic solution for cement and screw retained implant prosthetics and are strong enough to be used in all positions in the mouth.
    Chameleon® abutments work on most major implant platforms, giving you the freedom to choose the best solution for your patient.
    Using our unique virtual abutment design software, we design individual zirconia abutments within the final tooth shape. The result is an abutment with outstanding function and aesthetics, and the restorative procedure is simple with reduced chair time. It will also eliminate the need for inventory of stock abutments and have a fixed cost custom abutment since no precious metals are used.
    The CAD construction of Chameleon® abutments allows greater accuracy when designing emergence angles and paths of insertion. The highly polished zirconia collar provides better acceptance to the soft tissues and produces an exceptional aesthetic abutment for single and multiple cases.
    Terec laboratories are able to provide fully customised Chameleon® Zirconia abutments complete with screw and finished zirconia crown.
    The best aesthetic cement and screw retained implant prosthetic.

Can I send you Digital Scans?

We can accept digital scans compatible with 3shape and any files in STL format. There are so many different scanner systems that it would be best to contact Jay@McDowell-Service.com and she will try to accommodate you.

Can I send you files using Email / DropBox ?

Yes, we accept files using email and through our website. We also have different DropBox accounts depending on the type of file you want to send, Photos / STL milling files etc. We can also accept files via CD, USB device, SD card.

Can you take a shade for my patient in your lab?

Yes, we have our own shade taking room.

What tooth preparation is required for Fortress Zi?

One advantage of this type of restoration is that the preparation can be slightly more conservative than other all-ceramic or even PFM restorations, with a preparation design similar to that of a full cast metal crown. Margin design should be 0.3-0.5mm chamfer. Avoid a ‘J’ like margin. Functional cusps should be reduced 1.0-1.5mm. Axial walls should taper 6-8 degrees achieving a depth of 1.0mm. Occlusal reduction 1.0-1.5mm on the central groove. AND avoid all sharp line angles as you would with any type of all ceramic tooth preparation.

What is a Chameleon Zirconia restoration made from?

Chameleon Zirconia or PFZ is a metal free and highly translucent restoration, resulting in a more natural appearance than a PFM. Because Chameleon Zirconia restorations are made from Zirconia and overlaid with GC Initial Porcelain, both highly compatible materials which have been used in dental treatments for many years; thus can be placed next to tissue without any gum reaction.

What can I use as a metal-free alternative for a Maryland Bridge?

t is recommended that a Maryland Bridge be constructed as a PFM because it is strong, proven and bondable. However, the problem is a PFM Maryland Bridge is often unaesthetic due the possible ‘shine through’ of the retaining wings. A porcelain fused to zirconia Maryland Bridge is possible and may require a little more tooth preparation than what is usual for a Maryland retainer but zirconia does not etch and there is a history of Zirconia Maryland Bridges de bonding. For the latest information, please contact a technician.

Can I incorporate attachments into the Zirconia frameworks, as in a two part bridge?

All Zirconia framework are manufactured by CAD/CAM systems and as we use the industry Gold standard, 3shape software for design, various types of precision attachments are due to be made available with the very latest software update due to be released in 2015. Therefore, split bridges, combination cases with extra coronal attachments, telescopic copings and much much more will be available very soon.
