3Shape releases CAD solution for post and core restorations

COPENHAGEN, Denmark--3Shape, the provider of 3-D scanners and CAD/CAM software solutions for the dental industry, has launched a CAD solution for post and core restorations.

The solution includes dedicated post and core intraoral scanning with 3Shape TRIOS and CAD design workflows in Dental System 2013. 3Shape’s post and core solution uses special scanning capabilities, 3Shape Scan Posts, and sophisticated software tools for reliable capture and optimally shaped and functional post and core designs. The solution saves time by allowing lab technicians to design all layers in a single digital workflow.

3Shape has developed special Scan Posts to facilitate accurate capture of the post and core restorations’ positions and depths. Scan Posts are approved for intraoral use in the clinic and for model scanning in the lab. Scan Posts are autoclavable, and they come in various shapes and sizes to support drill systems from major suppliers. Patent Pending.

3Shape’s post and core solution can be used with 3Shape TRIOS digital impressions and 3-D scans of gypsum models. Dentists with 3Shape TRIOS can kick start post and core cases in the clinic by capturing and sending reliable input to the lab for direct designing.

A special dual-scan workflow using 3Shape Scan Posts helps ensure accurate capture of true depths and positions of the root canal. If gypsum models are the input source, lab technicians simply insert Scan Posts in the model before scanning.

In the lab, technicians align the captured Scan Posts and let the software calculate positions and depths automatically. By first designing the anatomy layer and applying dedicated post and core modeling tools, technicians can create optimally shaped and functional post and core designs that are matched to the clinical case and ready for manufacturing through wax print and cast, milling, or laser sintering.

Frederic Rapp, director of Crown Ceram dental laboratory in France said: “In combination with TRIOS, 3Shape’s post and core design software gives us a fast and easy way to model optimally shaped and robust post and core restorations. The full digital workflow makes it very easy to design parallel post and cores, or work with cases involving multiple posts.”

Labs can design post and core cases for standard crowns, single-piece retained crowns, and anatomical single-piece retained crowns that are cut back for veneering.

3Shape’s post and core design solution is fully functional in the released Dental System 2013 software and with 3Shape TRIOS. 3Shape Scan Posts are available for dental clinics and labs through 3Shape distributors.
