ARCUSdigma supports therapy & diagnosis

ARCUSdigma, instrument-based functional diagnosis: a milestone towards the "digital office" and ideal support for your diagnosis and therapy. It was never that easy!

  • When using the KaVo PROTARdigma articulator, model mounting does not require a facebow.
  • KaVo is the only manufacturer worldwide, offering an integrated solution in one KaVo treatment unit.
  • Perfect hygiene by customary smooth-surface wipe disinfection. Operation of the PC keyboard is unnecessary.


Solves your task!

With the KaVo ARCUSdigma, mandibular movements can be quickly and precisely detected. In addition, the system offers a fast, economical and practical application of specific and therapeutically relevant methods of instrumental function analysis. By increasing the number of sensors to four transmitters and eight microphones, the measuring precision has been substantially increased in comparison to its predecessor, the ARCUSdigma.


  • Integration into the treatment centre.
  • Integrated, electronic face-bow.
  • Can be operated without PC during measurement.
  • Integrated database with VDDS interface.
  • Export/import function.
  • Network software.
  • Compact design.
  • Battery operation possible.

Therapy support

  • Articulator programming for fully-adjustable articulators.
  • 3 methods for centric determination.
  • Analysis of a therapeutic position (for static splints).

Diagnosis support

  • Mandibular movement analysis.
  • Localisation of painful temporomandibular joint positions
(optional), for dynamic splints.
  • 3D comparison of arbitrary occlusal positions.
  • Analysis of muscle activity (EMG) optional.

Functional dental prosthesis

Savings, by massive reduction of occlusion adjustments in the patient's mouth.

  • Calculation of all settings for fully-adjustable articulators, in less than 5 min.
  • Upper jaw model mounting according to KaVo transfer system, or individual axis determination. With the option to select a large number of articulators from other manufacturers.
  • Analysis of the centric position of the lower jaw, for the lower jaw model mounting (optional with electromyographic support).


Without compromise, by customary smooth-surface wipe disinfection.

  • The ARCUSdigma concept is based on decades-long experience with hygiene.
  • Smooth, disinfectable pushbuttons and a foot-switch control all aspects
of the instrumental assessment.
  • The dentist does not need a PC keyboard, while taking measurements of the patient.

Temporomandibular joint diagnosis, treatment of CMD patients

ARCUSdigma analyses and documents all necessary data, for this highly-lucrative market segment.

  • Efficient movement analysis developed by professionals, for a profound diagnosis, displaying the kinematic axis and the incisal point.
  • Complete documentation of therapeutic progress, in movement analysis.
  • Determination of painful temporomandibular joint positions and calculation of dynamic splints
(according to Prof. Dr. Axel Bumann).
  • Analysis of a therapeutic position of the lower jaw, for static splints and definitive denture, respectively.
  • Optional communication with specialists, by means of a data export function, via the Internet.

Integration into the workflow

The cost-effectiveness of a practice is becoming increasingly important. Integrated solutions are the basic prerequisites for new technologies.

  • Compact design: immediately usable in all treatment rooms, without assembly.
  • Integration options for KaVo treatment centres.
  • The ARCUSdigma Software is network compatible. 6 Licenses for 10 terminals each.
  • Interface (VDDS) to numerous accounting programs.
  • Simple and faster programme update via the Internet.
