contact implant was placed, along with an internal sinus lift. After healing, the patient presented to my office for a digital impression. A preliminary scan of the gingivalformerusingtheCS3500intraoralscanner was performed. The gingival former was removed, a scanning body was placed into the implant and the CS 3500 was used to scan the scanning body as well as the rest of the maxillary arch and the opposing arch. ThedigitalfilewassenttoCore3-Dlabandacustom titanium abutment was fabricated. The abutment was shipped to dental laboratory (Digident Dental Lab in Orangeburg, NY) and a ceramic crown was fabricated after the general dentist picked a shade. Theabutmentwasplaced,torquedto32cmandthe crown cemented. Conclusion This case illustrates how digital dentistry can be used with implant dentistry. Frequently, a fixture level impression is taken and subsequently a model is poured up in stone; on top of which a custom abutment is made. Later the dental technician will fabricate a ceramic crown. Using the CS 3500 (Carestream) intraoral digital impression, the workflow is streamlined. By placing a scanning body and scanning it with the CS 3500, the custom abutment and crown are produced via a digital model. The abutment and crown are planned virtually, reducing patient chair time and overall case turnaround time._ digital impression industry report | 31 CAD/CAM 4 2016 about Dr Bart W.
