Straumann has been granted a patent for an additive method of producing a dental working model for an articulator. The method involves additively producing a base plate and dental model, which are fixed securely to each other. The patent also includes the production of a splint with a spring element to further secure the fixation of the base plate and dental model.

Additive method for producing a dental working model
A recently granted patent (Publication Number: US11771536B2) describes an additive method for producing a dental working model for an articulator. The method involves additively producing a base plate, a dental model, and a splint with a spring element. The splint is inserted between the base plate and the dorsal side of the dental model, exerting a force through the spring member to securely fix the base plate and the dental model together.
The splint can be configured as a wedge or a rail, with the spring element providing force- or form-fitting fixation. The base plate may consist of an upper and lower plate, and both the base plate and dental model have fixing elements at the vestibular end to securely attach them to each other. These fixing elements can be latching elements or bevels, aligned parallel to each other.
The bottom side of the dental model facing the base plate is partially open, allowing for the removal of stumps or implant analogs in an occlusal direction. The base plate and dental model are designed to be coupled magnet-free.
In addition to the method, the patent also covers an additively manufactured dental working model for an articulator. This model includes an additively produced base plate, dental model, and splint with a spring element. The splint is inserted between the base plate and the dorsal side of the dental model to securely fix them together.
Similar to the method, the dental working model has fixing elements at the vestibular end of the base plate and dental model for secure attachment. The fixing elements can be latching elements or bevels, aligned parallel to each other. The bottom side of the dental model is partially open, allowing for the removal of stumps or implant analogs in an occlusal direction. The base plate and dental model are designed to be coupled magnet-free.
This patent introduces an additive method and an additively manufactured dental working model that provide improved fixation and flexibility for dental articulators. The use of a splint with a spring element allows for secure positioning of the base plate and dental model, while the fixing elements ensure a stable connection. The magnet-free coupling and the ability to remove stumps or implant analogs enhance the versatility and functionality of the dental working model.
