Effect of Implant Analog Design and Additively Manufactured Casts’ Printing Layer Thickness on the Linear and Angular Accuracy of Analogs for Direct Digital Workflow: An In Vitro Study

The analogs in S-50 casts had positional trueness similar to or higher than those in other test groups, and their accuracy was mostly similar to those in CNV casts. Implant analogs for direct digital workflow deviated more toward lingual and gingival, and conventional analogs deviated more toward buccal, occlusal, and distal. All analogs had a tendency to tilt toward the lingual and distal directions.
