Achieving the gold standard in dental aesthetics : manufacturing individual prostheses by measuring mandibular kinematics
Lately , more and more dental equipment companies have introduced devices to measure the movement of the lower jaw to increase the customization of prostheses . Many years ago I came to familiarize myself with such a mandibular kinematics recording device , JMAnalyser + from Zebris Medical GmbH . I used that device to make measurements in a batch of patients under a multicenter research grant whose director was my father . During the IDS 2017 , I noticed a multitude of devices to measure mandibular kinematics . I took my father to the Zebris Medical GmbH stand ( Am Galgenbuehl 14 , D-88316 Isny , Germany ) we learned from engineer Wolfgang Brunner , one of the owners , that his company manufactures a wide range of devices for the recording of mandibular kinematics at SAM- Dental , KaVo , Dentsply / Sirona , Schütz Dental GmbH , etc . Out of the products on display we noticed the new JMAnalyser + - Face Imager multifunctional device on an adjustable mobile holder .

The JMAnalyser + measuring system is manufactured according to the method of measuring the travel time of ultrasound impulses . It is made up of a face bow with integrated receiver modules and a balanced mandibular sensor . The sensor is fastened on the paraocclusal lower jaw attachment by means of a magnetic holder . The measurement data are transmitted to the evaluation computer cable-free via a Bluetooth or USB interface . The basic unit can be comfortably worn by the patient via a retaining strap to the neck . The system records all degrees of the lower jaw mobility contact-free . The measuring range allows functional and occlusal analysis , recording of parameters to adjust the mechanical and virtual articulations required for individual prosthesis and occlusal splints , determination of the neuromuscular mandibular relation , and electronic position analysis of condyles ( EPA ). The system is ready for export of individual motion data and forms an interface in the digital workflow . The patented bite forks connect actual motion data to dental surfaces of intraoral scans . The movements are then exported through XML files to a CAD / CAM or CBCT systems . The evaluation software WINJAW + convinces via a structured and modular surface that works with the wireless pedal or PC keyboard . This software is based on the integrated database and the individual measuring modules configured individually according to the user ' s requirements . Each movement is recorded in real-time on the screen and can be repeated at any time . The Face Imager module identifies the facial aesthetics of the patient using the camera and intuitive software to facilitate manufacturing functional prosthesis and occlusal splints . The additionally available integrated 4 channel EMG module allows the analysis of the muscle action potentials using bipolar surface electrodes . The biopotentials collection takes place on both sides with integrated electrode cables with integrated amplifiers . The system allows functional tests of the anterior temporalis and masseter muscle groups . The EMG activity is accurately and reliably detected without cable artifacts . To conclude I can assure you that the JMAnalyser + - Face Imager multifunctional system convinces by its simple operability and compact size , as it is ready to help you record the exact mandibular kinematics required to manufacture individual functional prostheses that fully satisfy your patients ' aesthetic requirements .
