The dental procedure in the Baltic Denture System provides for impression-taking, bite registration and transfer. The BD KEY® Set, which was developed for this purpose, creates the process steps in the dental practice safely and quickly and transmits the key data to the lab.

In the first step, the patient-specific size of the PMMA BD KEY® is determined by using the PEEK Upper- and LowerKEY. The Upper- and LowerKEY made of PMMA as well as the KEY® Lock are subsequently used for the functional impression by applying BD Impress®, in order to check the aesthetics of the row of teeth (try-in) and to determine the correct position of the occlusal plane. The vertical and horizontal lock of the Upper- / LowerKEY to determine the jaw relation is carried out by using the BD KEY® Lock. The PMMA BD KEY® stand out through their good and easy workability with rotating instruments and can be adapted to the individual patient situation by grinding.

Upper- and LowerKEY in S, M and L sizes with a reduced base portion for adding the impression material show dental arches that are congruent to the corresponding BD Load®. This allows an aesthetic check of the dental arches as well as their correct alignment position in the interalveolar space.

Visualization of the occlusal plane and center of face is done with BD KEY® Plane and KEY® Fin, which are affixed to the UpperKEY. The UpperKEY is correctly positioned relative to the occlusal plane and center of face by filling the entire surface with impression material. A suction action is necessary for the following workflow. The subsequent encoding of both BD KEY® makes it much easier to define the patient specific jaw relationship, which is then fixed in the basal area of the LowerKEY with the impression material.

The wax try-in no longer required is now replaced by a check of the centering, of the functional movements and aesthetics, e.g. smile and lip closure line. The patient can see his/her future smile.

The Upper- and LowerKEY thus serve as an aid in gathering and transferring important aesthetic and functional information, which can be applied in the digital design process in the dental lab at a later date.
