3D viewers
This section is reserved for lightweight STL, PLY, OBJ and DICOM viewers suited for case review, patient communication and design verification.
This page collects practical 3D viewers, CBCT/DICOM viewers, and slicers commonly used in digital dentistry for case review, implant planning support, print preparation, and design verification.
Most of the tools below are free. CHITUBOX Dental is included because it is relevant to dental resin workflows, but its official site currently presents it as a free trial with paid licensing after that.
