Abstract: A touch screen interface of a medical or dental device coupled with a touchless interface to allow for sterile zone operator input, while still allowing for touch screen interaction for non-sterile zone operator input. In some embodiments, the touch screen interface usage is suspended while in a sterile zone mode, and resumed when the mode is switched to a non-sterile zone mode. In some embodiments, use of the touch screen interface while in a sterile zone mode of operation causes an alert message.

Abstract: A dental model articulator of the type that has separable complementary articulation members is connected to a registration object having compatible complementary articulation members. The dental arches of each dental model articulator half is scanned with the reference object to give the axis of the articulator model. This facilitates generating a virtual dental model.

Abstract: A method and system is provided for designing a three dimensional model of a dental prosthesis. Separate components having distinct functions are identified in the prosthesis and designed separately. The components are then juxtaposed spatially to form the dental prosthesis model. Different designing tools are used to design each component separately such that each shape is matched with an editing and designing tool that best suits its particularities.

Abstract: A method for producing a dental prosthesis includes computer modeling of a three-dimensional prosthetic cap based on an human implantation zone. The method first includes casting an impression of the implantation zone of the human body. Then, on the basis of the moulded impression, a digital three-dimensional representation (R1) of the implantation zone is made by sensing the implantation zone with a sensor. From this, a digital representation (R1c) of the internal surface of the prosthesis is defined on the basis of the digital three-dimensional representation (R1) of the implantation zone. A digital three-dimensional representation (R2) of the external surface of the prosthesis is then defined on the basis of the surrounding parameters of the prosthesis and the digital three-dimensional representation (R1c).
