ARCUSdigma supports therapy & diagnosis

A milestone towards the "digital office" and ideal support for your diagnosis and therapy

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

KaVo ARCUSdigma


  • 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


Treatment unit with ARCUSdigma

Perfect visualisation by integration into the treatment centre

Utilise the patient oriented visualisation of the ARCUSdigma software as a targeted marketing measure in your practice: During the measurement with the ARCUSdigma and in the following counselling interview, all movements will be displayed on the monitor in an easily understandable way.

Statements and information from the patient, can be documented via a special input field and can be assigned to the patient, in the ARCUSdigma database.

Presentations of a course of therapy by measurements prior to and after the therapy support the dentist in the daily practice routine. The measures data can be digitally transmitted to practices and laboratories worldwide.

KaVo is the only manufacturer worldwide, offering an integrated solution

The ARCUSdigma can be mechanically adapted to the assistant element of the KaVo ESTETICA E70/E80 treatment unit. Data transfer follows via the optional USB interface on the unit.

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

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.


Electronic movement analysis in prosthetic therapy

The expenditure of time for correcting malocclusions and the danger of damaging the ceramics when carrying out such corrections, can be largely or fully avoided by a movement analysis.

The ARCUSdigma takes only a few minutes, to precisely determine all articulator settings and supports the dentist in determining the centric position of the lower jaw.

Electronic movement analysis in the diagnostics

Temporomandibular joint troubles are being diagnosed for an ever-increasing number of patients. The ARCUSdigma analyses and documents temporomandibular movements and the therapeutic process for profound diagnostics.

ARCUSdigma localises painful temporomandibular positions, using special, optionally available analytical software (according to Prof. Dr. A. Bumann). An integrated calculation module, permits the practice-oriented therapeutic realisation of the findings, with the KaVo PROTARdigma articulator, immediately after the diagnostics.

Thus, it becomes possible to realise not only the therapeutically necessary occlusion, but for the first time, also to carry out dynamic occlusion in the dental laboratory and not be limited to achieving this time-consuming procedure in the dentist's chair.
