CAD/CAM

What CAD/CAM components does DESS offer?

  1. Scan Bodies $25 (made of PEEK Plastic)
  2. Ti Bases - Engaging and Non Engaging and on top of Multiunits $39 (includes both a wax up sleeve and a final screw)
  3. Chrome cobalt bases - Engaging and Non Engaging and on top of Multiunits $45 (includes both a wax up sleeve and a final screw)
  4. FREE library files for Exocad®, 3Shape®, and Dental Wings® (all approved by scanner manufacturer)

What CAD/CAM scanner software does DESS work with?

Exocad®, 3Shape® (2014 software), and Dental Wings® support DESS library files. Every time DESS creates a new library file it is sent to these companies who approve them prior to being released on our website. As a result of new FDA guidelines 3Shape® will not allow non FDA approved Ti bases and scan. Once DESS receives FDA approval we will have a new library file to be used in 3Shape®. For now if you have 2014 you can scan with the scan bodies and design with the ti bases like you have done so already. If you utilize 2015 you can scan DESS Ti bases/Scan Bodies as preps.

The library files can be downloaded here - https://www.dess-usa.com/library-files/

What scan body solutions does DESS provide?

Currently DESS has scan bodies made of PEEK plastic that are autoclavable and library files for Exocad®, Dental Wings®, and 3shape®. For the Dental lab they can utilize the scan bodies to scan single unit and implant bridge cases (both on top of implants and multiunits). The scan bodies can be altered/thinned down on side walls however the top ball and flat side need to remain intact. The top ball with flat side provides the orientation, angulation, and depth of the implant. This information is then transferred to both the titanium base and the analog so they can be virtually placed into the model within the cad software so that the dental technician can design the restoration. The flat side on the titanium base also serves as a antirotation feature.

DESS Dental Lab Scan Body

These scan bodies are not designed to be used intraorally.

DESS will be introducing new intraoral scan bodies in the near future. They will be shorter and narrower. These will be tested to work with the open architecture intraoral scanners from 3shape®, Dental Wings®, Carestream®, 3M® True Definition and others.

DESS Titanium Base

What are the DESS ti base/scan body unique features?

  1. Free scan library files of analog, screw, ti bases, scan bodies, and multiunit/uniabutment/1.5 abutments enable labs to virtually plan entire full mouth temporary and final restorations from implant level impressions.
  2. Scan bodies made of PEEK plastic, designed by Exocad®, with extremely high accuracy.
  3. Ti Bases/Scan Bodies include a final screw and wax up sleeve for making various solutions without the need to outsource.
  4. The wax up sleeve has an anti-rotational and step pattern so it fits exactly in one way onto the ti base.
  5. SelectGrip® surface on Ti Base/Scan Body eliminates need to sandblast surface, provides lab with a uniformed roughened surface with 3 times greater retention then standard titanium surface.
  6. All screws tested to be torqued to 150% of nominal torque setting.
  7. Engaging, Non Engaging, and Multiunit Ti Bases/Scan Bodies available for all systems
  8. Angulated screw channel ti bases coming soon. Currently many labs have used these screws with existing ti bases and all plastic sleeves successfully.

What type of CAD/CAM restorations can be made with the DESS ti base/scan body?

  1. Print out Wax and Cast a PFM separate from the ti base and then CEMENT it onto the ti base as either a cement or a screw retained PFM abutment crown.
  2. Print out Wax and Cast a PFM separate from the ti base and laser weld it onto the ti base as a screw retained PFM abutment crown.
  3. Mill an Emax and cure/lute/bond/cement to the ti base
  4. CAD/CAM mill a zirconia abutment and then cure/lute/bond/cement to the ti base
  5. CAD/CAM mill a one piece screw retained zirconia abutment/crown and then cure/lute/bond/cement to the ti base

What other parts are included with the DESS ti base/scan body?

All of the DESS Ti Bases/Scan Bodies include a final screw and wax up sleeve. The ti base has a flat side which correlates to both the scan body and the analog as well as the wax up sleeve. The wax up sleeve can only be placed onto the ti base in one way (aligning the flat side on both parts) so the fit of any component that you create with the wax up sleeve will have built in anti rotation.

What type of restorations can be made on top of the ti base utilizing the wax up sleeve?

  1. Wax and Cast a PFM separate from the ti base and then CEMENT it onto the ti base as either a cement or a screw retained PFM abutment crown.
  2. Wax and Cast a PFM separate from the ti base and laser weld it onto the ti base as a screw retained PFM abutment crown.
  3. Press Emax to the ti base
  4. Copy mill a zirconia abutment
  5. Copy mill a one piece screw retained zirconia abutment/crown

Does DESS have internal threaded ti bases/scan body?

DESS has designed additional precautionary features into several of the conical shaped platforms that have "engaging elements" which may possible bend under applied pressure. This includes the Nobel Active®, Straumann Bone Level®, and Ankylos® compatible ti bases.

They have their own internal safety threads inside them. This means that the screw cannot fall out of the abutment unless the user consciously chooses to unscrew the screw from the abutment. By having this internal abutment thread to keep the screw in situ then all external pressure on the engaging elements is supported by the screw and it is virtually impossible to bend them.

So the “instructions for use” should be to ensure that the screw is threaded through the abutment whilst restoration takes place and before placing in the analog or implant. If this precaution is observed the engaging elements remain safe from possible damage. If for any given reason, the screw needs to be removed, place it back again in its “safe” position before applying any loads on the abutment. In order to prove the resistance of this modified design DESS has conducted a static stress test on the 2mm high Ti bases (compatible with Ankylos) and the results are quite impressive as the load to bend them is clearly above 500N at 30º.

How can the DESS library files be utilized in my CAD software?

The DESS library files for Exocad®, 3Shape®, and Dental Wings® provide you with CAD files of the following DESS components; Analog, Scan Body, Ti Base, Final Screw, and Multiunit Abutments.

During the scanning process the scan bodies top portion (the ball with flat side) provides information to the CAD software of the orientation, depth, and angulation of the implant placement. This information is then incorporated into the 3D model with the analog and ti base being inserted into the right orientation, angulation, and depth based on the scan body scan. The CAD file of the screw is included so you can see the depth, angulation, and insertion of the screw in the ti base and restoration. This is especially important for when you make an angulated screw solution with our upcoming angulated screw channel ti bases/scan body.

DESS manufacturers several multiunit abutments and by providing you the library files for these components you can virtually plan out any multiple implant case with our CAD file of the multiunit abutment and create, prior to insertion of the multiunits, temporary or permanent implant bridge solutions and deliver both the restoration and DESS multiunit components to the dentist at time of surgery/after healing etc.

There are several companies in the USA that manufacturer custom titanium and custom zirconia abutments and they require that you purchase their own scan bodies. DESS scan bodies only work with the DESS ti base and the fabrication of the restoration above that.
