The extremely automated and clever interplay between software program and {hardware} permits the manufacturing of biocompatible indications with correct, reproducible and medical-grade outcomes.

Within the following case research, Mike Skramstad, DDS, shares how Primeprint matches inside his present digital workflow to supply a 3D-printed wax-up and Primeprint Mannequin resin to point out the affected person what the completed process would appear to be whereas additionally creating guides, temporaries and a Biocopy for ultimate restorations.

Case description

A 47-year-old feminine offered to my workplace with considerations about six anterior zirconia crowns just lately completed at one other workplace.

She additionally complained of tooth sensitivity and occlusion that was not even and bothered her every day.

After preliminary session, pictures and intraoral scans with Primescan AC have been taken to carry out a complete session. Having the digital impressions and images assist visually talk about her considerations and create worth for pursuing remedy. After the plan was finalized, all scans and footage have been despatched to our laboratory to create a digital wax-up. After finalization, I 3D printed the wax-up with Primeprint and Primeprint Mannequin resin. This bodily mannequin of the plan allowed me to current a

preview of remedy to affected person, create preparation guides, make correct temporaries, and use as a Biocopy for ultimate restorations. To finalize the proposed plan, we transferred the wax-up to the mouth with bis-acryl materials on the second appointment. She accepted and was excited for remedy. On appointment three, I ready full protection crowns on tooth #6-11 and veneers on tooth #5 and #12. We scanned the ultimate preparations, opposing dentition, 3D printed diagnostic wax-up within the Biocopy Folder, and Buccal Chew with Primescan AC. After margination of the preparations within the CEREC 5.2.3 software program, we despatched case to inLab SW 22. This software program allowed us to create a stable mannequin (with ditched dies) and a working mannequin with detachable dies. This accomplished mannequin information was despatched to inLab CAM 22 and 3D printed with the Primeprint out of Primeprint Mannequin resin. The effectivity and ease of use of

the Primeprint Resolution permits me to shortly print fashions on the identical day of remedy. The automation permits me to proceed with my design work with out having to fret about monitoring the printing course of, manually cleansing resin, or coping with messy alcohol. It took roughly 50 minutes to print each the stable and dealing mannequin and below 45 minutes to clean and treatment. After ultimate design, all restorations have been produced out of glass ceramic with CEREC Primemill utilizing the extra-fine mode.
