Voxel-Man is a pioneer in medical visualization and simulation technology.

The Voxel-Man project dates back to around 1985, when a research group headed by Professor Karl Heinz Höhne at the University Medical Center Hamburg-Eppendorf made their first experiments on 3D visualization of tomographic images from CT and MRI. At RSNA 1987, the first ever 3D reconstruction of the complete brain of a living human being could be presented.

Today, Voxel-Man simulators are used by leading universities and hospitals in more than 20 countries, virtually between Honululu and Tokyo. The growing interest in our simulators is also reflected by an increasing number of independent validation studies.


is a new kind of dental simulator, based on virtual reality technology. Students are working on simulated patient cases with a look and feel close to a real procedure, training both their manual dexterity and problem solving skills.

With its striking new features, VOXEL-MAN Dental greatly improves quality and cost-effectiveness in pre-clinical training—and beyond.

At present, pre-clinical dental training is mostly based on drilling resin tooth models. Unfortunately, these are made all of one material, making it impossible for a dental student to develop a realistic feel for the different dental tissues. Even worse, the teeth usually have no pathologies, such that training is limited to standard preparations. An objective assessment of the student’s skills and progress is hardly possible.

See and Feel the Difference

In VOXEL-MAN Dental, teeth and instruments are modeled in high resolution inside a computer and visualized on a 3D screen. The dental handpiece is represented by a force feedback device which can be moved in three dimensions and provides a very life-like sense of touch. With VOXEL-MAN Dental, you can actually feel the subtle differences between enamel, dentin, pulp, or carious tissue.

Instruments provided include a selection of high and low speed burs of different shapes which are controlled by a foot pedal, as well as a dental mirror. At any time, teeth may be inspected from all sides, magnified as desired, and even shown as cross-sectional images. The high resolution tooth models have been derived from real teeth by microtomography.

Problem-Based Training

voxel-man-dental-vr-simulation-exampleVOXEL-MAN Dental is fully integrated with a dental curriculum. The dental models include carious lesions at various locations, such as mesial, occlusal, and distal tooth decay. Students thus work on realistic cases, including development of a treatment plan and removal of caries, long before they see their first real patient. This approach provides a major step ahead from prescribed standard preparations to problem-based training, bridging the gap between theory and practice. All procedures can be practiced as often as needed, with no costs for disposable parts. As all students undergo standardized training procedures, results are comparable.

Skills Assessment

As a step further, VOXEL-MAN Dental also includes an automatic skills assessment. Both process and result of a student preparation can be evaluated objectively, based on predefined standards such as a reference preparation of a cavity or a crown. Hence, students get immediate feedback on their work, progress over time can be monitored, and instructors have more time available for real teaching.

The automatic skills assessment also allows for a great deal of additional self study, reducing the demand for supervision.
