Intraoral scanners offer 3D scanning of the upper and lower jaw as well as the bite. In only a few minutes the digital impression is done and may be used for production of various dental restorative products such as crowns, bridges etc.
It is an alternative to traditional impression taking using trays with impression material.
Using an intraoral scanner is a more controlled way to take impressions as it has the same accuracy no matter who does the scanning. It also saves time transporting the impressions to the dental lab as compared to traditional impressions. When the lab receives the digital impression file by electronic means, they can initiate the design of the restoration immediately as there is no need for any further preparations or scanning of a physical impression or model.
The scan file is imported into a CAD program for design of the restoration. The lab can thereafter mail the design proposal by mail to the dentist who can quickly validate the design. Production can start immediately after that.
During production of the restoration, a plastic model of the scanned jaws is produced to enable a final control of the fit and occlusion before seating in the patient.
Studies have shown that high quality intraoral scanners match the accuracy of the best lab scanners scanning gypsum models.
The Heron IOS is a lightweight, ergonomically designed, easy to use scanner that is able to capture the entire teeth surface in minutes. The user is guided by the included Chairside software allowing the user to do basic CAD design, if so wished or - alternatively - simply forward the scan to a dental lab of his/her choice. For users with their own in-house dental technicians a full dental CAD package is available.
Benefits of using an intraoral scanner are higher patient comfort, reduced handling related variance in accuracy, saving time on logistics, saving time in the design and production of the restoration, greater flexibility in selecting the lab, elimination of impression re-takes, better fit of final restoration, reduced chair time, better communication with patient and a general faster workflow.
