Plaster-free articulation of dental models – Easy to design, easy to produce

Driven by passion we have been working tirelessly over the past years to provide our customers with new solutions which ensure better results. With our technologies, we want to further improve the efficiency and quality of the daily workflows in clinics and laboratories. For this reason, we developed our new JawAligner – an innovative system to increase the techno-clinical cooperation. Enrico and Julian Steger 3

THE JAWALIGNER The new JawAligner are magnetic spacer plates which allow to fix in the articulator printed or milled models without using plaster. Available in different heights, they permits material saving and the articulation of models indipendently of their height. Moreover, the two sets – one inclined and one straight – allow to articulate models according to the occlusal plane inclination. Thanks to the standardised connection and the corresponding JawAligner, milled or printed models can be magnetically fixed in Zirkonzahn’s PS1 articulator, GS1 plaster articulator and Mini-Arti ZS1 to...

AN EVEN MORE COMPLETE DIGITAL WORKFLOW With the Detection Eye intraoral scanner, the P4000 system for 3D printing and the JawAligner, we provide dentists and dental technicians with a complete pre-set package where all components are perfectly compatible with each other to ensure a simple and uniform workflow. Based on the oral situation acquired with the intraoral scanner, models are designed in the Model Maker module of the Zirkonzahn.Modifier software and printed by means of the pre-configured P4000 system for 3D printing or milled with Zirkonzahn’s milling units. The models can be then plaster-free...

WHY USE THE JAWALIGNER? The hardening process of plaster might cause deformations to the printed models. For this reason, a plaster-free articulation with the JawAligner is recommended in order to avoid inaccurate results. Furthermore, the use of the JawAligner ensures a precise occlusion check, which in conventional articulation methods can be compromised due to plaster expansion. In a dentistry field more and more focused on intraoral scans, the JawAligner system also allows to easily transfer the virtual patient’s jaw position into the laboratory articulator for final control or case delivery...

TRADITIONAL ARTICULATION VS. JAWALIGNER SYSTEM Long waiting times Time-saving: no need to create plaster models or wait the hardening process is complete Full digital design Material waste No material wastefulness thanks to the different JawAligner heights Possibility to create the model with a honeycomb structure ensuring greater stability Risk of errors due to plaster expansion during the hardening phase, leading to a possible wrong occlusion Any deformation of resin models or errors due to plaster expansion is avoided, ensuring a correct occlusion Thanks to the two available sets, dental technicians...

COMPATIBILITY OF THE JAWALIGNER CONNECTION Thanks to the standardised connection and the corresponding JawAligner, milled and printed models can be fixed in Zirkonzahn’s PS1 articulator and Mini-Arti ZS1 to simulate patient’s jaw movements. Optionally, it can also be used with the GS1 plaster articulator.

Physical and virtual articulator designed with special geometries to simulate patientspecific rotating, sliding and closing jaw movements. In Zirkonzahn scanners, models can be scanned together with the PS1 and then transferred into the virtual articulator. Articulator for plastering models and checking opening and closing movements, specially conceived to protect the PS1 articulator from plaster residues and water. A specific calibration key creates a synchronisation with the PS1. Small articulator conceived for checking the occlusion of small bridges and single crowns, which can also be used...

DIFFERENT HEIGHTS The JawAligner are available in different heights, permitting the articulation of models independently of their height. Depending on model requirements, the different JawAligner heights can be combined with each other to create a more structured model and save resin.

INCLINED AND STRAIGHT The JawAligner system consists of two sets, one inclined and one straight, which allow to articulate models according to the patient-specific occlusal plane inclination. These two different sets were specially developed to provide models with great stability, avoiding deformations caused by an unbalanced front-rear height and permitting their articulation regardless of the inclination degree. Thanks to the different heights and inclinations of the two JawAligner sets, any model can be placed in the articulator, even, for example, implant models with particularly long laboratory...

MODELS CREATION WITH THE JAWALIGNER SYSTEM Especially when dealing with printed models, the hardening process of plaster might cause deformations. The innovative JawAligner system, completely integrated into Zirkonzahn’s digital workflow, not only ensures a plaster-free articulation but also saves time and material. After taking a digital impression of the oral situation with the Detection Eye intraoral scanner, the acquired data can be transferred into the Zirkonzahn.Modifier software, for models design. To use the JawAligner, first of all choose the articulator in the Model Maker module. Then...

Depending on model requirements, the spacer plates can be combined with each other to create a more structured model and save resin during printing. Once the creation of the models is complete, the software creates the corresponding attachments in the model bases. You can also set parameters between spacer plates and models (e.g. creation of a honey comb structure for more stability, increase of base thickness, attachment adaptation or compensation of possible layer imprecisions).

At this point, models can be printed with the 3D P4000 System or milled in Zirkonzahn’s milling units. Remove the screw and clean the screw housing from all resin shavings left from the screwing process. Note: according to the model weight, two different metal plates can be used, showing lower or higher magnetic strength: 1 mm and 1.5 mm. Fix the threaded screw up to its halfway point. Place the magnetic plate in the attachment and fix the screw. If desired, it is also possible to glue the plate directly to the model. If there is any resin excess in the two small antirotation attachments, use...
