A method for producing a dental prosthesis, and a dental prosthesis made according to the method, the method having the following chronological steps:

Device and method for holding prosthetic teeth

Method for producing a three-dimensional model of at least a partial jaw comprising: fully-automatic shaping of at least one recess for accommodating a laboratory analogue into the alveolar ridge of the model using three-dimensional scanning data and shaping the depth, position, and orientation of the at least one recess such that the crestal end of the laboratory analogue inserted into said recess coincides with the crestal end of the dental implant in the jaw; or fully-automatic shaping of at least one vestibular, lingual or palatinal feed-through through the model into the at least one recess using three-dimensional scanning data and arranging the feed-through such that the crestal end of a laboratory analogue coincides with the crestal end of the dental implant in the jaw when the laboratory analogue is fixed in place with a pin inserted through the feed-through in the model into an opening in the laboratory analogue.

Methods for producing a laboratory analogue for dental implants

The invention relates to a device and a method for the production of three-dimensional objects, in particular of at least parts of dental prosthetic restorations, by a stripping device wiping off plastic material, which protrudes vertically beyond a container, into a collecting container and forms a projection surface. According to the invention, a stripping device and a light source are coupled and simultaneously guided, at a defined distance, across the liquid light-curing plastic material, whereby the stripping device is guided at a defined distance right ahead of the light source and forms the projection surface for the illuminated field of the light source.

More efficient method for producing three-dimensional objects by means of a rapid prototyping process

The invention relates to a device for holding prosthetic teeth (), the device comprising a negative form () and at least one clamping unit (), wherein in the negative form (), recesses () for holding coronal sides () of the prosthetic teeth () are provided, wherein the recesses () are formed in such a manner that the prosthetic teeth () can be inserted in an unequivocally position and orientation into the recesses (), wherein the at least one clamping unit () is affixable or is affixed to the negative form () with a connecting means (), and wherein the at least one clamping unit () has at least one elastic holding means (), wherein with the at least one elastic holding means (), an elastic force is exercisable or is exerted from at least two different directions onto the prosthetic teeth () inserted into the negative form (), while the at least one clamping unit () is affixed to the negative form (), so that the prosthetic teeth () are affixed in the device. The invention also relates to a method for affixing, and preferably processing, prosthetic teeth () and a set for implementing such a method, having several prefabricated prosthetic teeth () and at least one such device.

The present disclosure provides a dental bridge intermediary structure comprising a superstructure () and a reference plate (), with distance pins () connecting the two. A method for producing a dental bridge superstructure () is also provided.
