ARCUSdigma
3D-ultrasonic navigator for diagnosis and therapy
No compromises with occlusion - KaVo ARCUS©digma Sender/Receiver.
The featherweight lower jaw sender (22g) together with the contact-free measuring principle enable a fast and easy fixation at the lower jaw.
Thus completely ensuring no impairment of the mandibular movements by the sensing system.
The functional principle:
ARCUSdigma functions on the basis of a 3D ultrasonic navigator. Operating at a frequency of 40 KHz at a rate of 50 times per second, results in 12 measured segments of the lower jaw movement in relation to the patient’s cranium. This 3D survey provides the necessary information for diagnosis and therapy.
Not much larger than the length of a mouth-mirror. KaVo ARCUSdigma Control Unit: High Tech in the smallest space.
The central control unit is directed via a color display with Touch Screen. For documentation purposes, a thermal printer or a chip card writer can be connected to the provided serial interface. Similarly, the serial interface allows for the possibility of updates. Due to its small size, ARCUSdigma can be installed practically anywhere in the dental treatment area.
The economic solution - for Prosthetic Therapy.
Occlusal adjustments:
Above all on modern porcelain materials, this is primarily difficult and often timeconsuming. If any necessary functional adjustments are not carried out, there is the risk of damage to the stomatological system or to the prosthesis.
Valuable time is lost, time which has a negative effect on profitability. Occlusal adjustments are above all necessary when information of the patient’s mandibular movements is not available.
With the help of ARCUSdigma, all relevant programmable values for the fully-adjustable KaVo articulator PROTAR 7 are reliably determined, and in the shortest possible time.
After fixing the para-occlusal attachement, all relevant data is established in less than 5 minutes.
The economic solution - for Functional Analysis.
According to the software module, functional analysis additionally allows movements of the mandible to be examined for functional disturbances during the course of the movement. However, the module should be considered as an initial step – the necessity for a functional pre-treatment by use of restorative measures should actually be carried out, and not overlooked.
Failures in the projected representation of the condylar and incisal movements in all three dimensions have been eliminated. By the simultaneous observation of the condylar movements on the left and right sides in the form of the kinematic axis, clues to movement limitations, un-coordination or hyper-mobility are obtained. The possible causes thereto in the arthrological, myological or occlusal areas are to be considered. In the Record mode all relevant movements up to 12 seconds long can be repeated as often as required.
With the help of Electronic Position Analysis (EPA) various centric registrations can be quantatively compared with each other, or in relation to a non-recorded specific lower-jaw location in the centric condylar position. Of course, a comparison between the centric and habitual occlusal position in the condyle area can be carried out. Further, it is possible to evaluate bite splints with regard to their determined lower-jaw position in relation to the reference point of the mandible.
