Zfx™Baltic Sistema di Protesi

Computer-aided production of complete dentures

Is it possible to produce high-quality full dentures in a time-efficient and economic procedure? The answer is yes – with the innovative Baltic Denture System (Merz Dental). Now, Zfx is happy to present an update for integration of this innovation, which is composed of a transfer kit for the dental office, software modules and adapters for scanner and milling machine, into the company’s own CAD/CAM system. The update is available for users of the desktop scanners Zfx™ Evolution and Zfx™ Evolution plus as well as the milling machine Zfx™ Inhouse5x as of March 2017.

For the production of the Baltic dentures, the laboratory receives a functional impression as well as the encoded Upper and LowerKEYs of the BDKey® Set (Merz Dental). The encoding of the keys is used to transfer information about the occlusal plane, the facial midline and the jaw relations into the virtual world.

In the laboratory, models are produced on the basis of the functional impressions. They are then digitized with the scanner Zfx™ Evolution or Zfx™ Evolution plus. In addition, the encoded keys are mounted in the Zfx™ Baltic Denture Holder and scanned as well. Subsequently, the generated digital datasets are imported into the new CAD software module BDCreator®, which automatically carries out a model analysis needed for selection of the correct blank with an integrated functional setup of the teeth. The blanks come in three different sizes and jaw widths. Once the blank is selected, the teeth are virtually positioned in the intra-alveolar space using the information obtained from the encoded keys and the denture base is generated

The design data can now be sent to a Zfx™ Authorized Milling Center or used for in-house production with a Zfx™ Inhouse5x. For the latter option, a CAM software upgrade and a specific blank holder are available. Their use is a prerequisite for an ideal milling path calculation and correct positioning as well as processing of the blanks in the milling machine. The described workflow leads to the elimination of several work steps in the practice and laboratory and thus offers the benefit of a time and cost-efficient production of complete dentures.
