Transferring the tooth preparation finish line on intraoral digital scans to dental software programs: A dental technique.

Intraoral scanner software programs allow the clinician to draw the tooth preparation finish lines. However, this information may be lost when importing the digital file into different computer-aided design (CAD) dental software programs. A technique for transferring the marked tooth preparation finish line into an intraoral digital scan is described. The intraoral digital scan of the tooth preparation is duplicated and used to draw the finish line. Subsequently, the tooth preparation geometry is erased while maintaining the finish line border, which will be used as a reference when designing the definitive restoration in the CAD software program.
