High Print Accuracy

DB 4000 delivered 97% global accuracy within ±130µm and 95% intaglio accuracy within ±100µm, surpassing the category leader.

DB 4000 is designed to minimize deviation between the original STL file and the final printed denture. This level of dimensional accuracy helps produce appliances that closely correspond to the patient's digital scan, supporting a predictable fit, improved suction, reduced tissue abrasion, resulting in greater clinical confidence and a better patient experience.
