The transition from analog to digital wax-ups has been one of the most impactful changes in restorative dentistry. But what exactly does digital offer that traditional hand-layering cannot?
Accuracy
Digital wax-ups are designed on verified digital models, eliminating stone expansion error. Studies show digital wax-ups achieve marginal accuracy of 25-40 microns compared to 80-120 microns for analog techniques.
Speed
A full arch diagnostic wax-up can be completed digitally in 2-3 hours versus 6-8 hours for hand-layered wax. This speed advantage allows multiple design iterations before finalizing.
Versatility
The digital wax-up can be instantly exported as a printable STL for mock-up try-in, used as a radiographic template merged with CBCT, or serve as the direct foundation for the final restoration design. A single digital wax-up file drives the entire workflow.
