Abstract: A hybrid abutment for restorative dental systems includes a restoration interface with an overdenture portion and a restoration portion that are each operable to couple to a plurality of restorative abutment components along a restorative axis, a receiver interface with at least one region operable to couple to a corresponding region on a receiver along an installation axis, and a restorative platform separating the restoration interface and the receiver interface. The restorative abutment component can include an overdenture or a restorative component with an optional resilient insert. The overdenture and the restorative component are interchangeable without switching either the hybrid abutment or the receiver. The hybrid abutment includes a main body with a single-build or multi-piece build or configuration. Where the receiver is an implant, at least a portion of the hybrid abutment and the implant can be formed as a monolithic component.

Abstract: A dental implant system that can include a prosthetic assembly and a dental implant. The prosthetic assembly can include a dental component and a retention screw. The dental component and the retention screw each have interference elements that are configured to engage when a removal torque is applied to the screw. When the interference element engage each other, a portion of the removal torque is converted into a linear force that is exerted on the dental component in a removal direction thereby separating the dental component from the dental implant.

Abstract: Systems and methods are described herein for fitting of a dental analog. In an embodiment, a test block may be printed that includes a number of analog pockets of different sizes. A dental analog may be tested within the analog pockets to determine which analog pocket provides the best fit. Once the best fitting analog pocket is identified, a corresponding library file describing the geometry of that analog pocket is identified, and a dental prototype model may be 3D-printed using analog pocket geometry based on the analog library file. By printing using common printing parameters and the identified analog library file, the resulting printed dental prototype provides the same fit as the analog pocket identified within the test block. This use of a test block reduces or eliminates the need for iterative cycles of printing and testing multiple printed dental prototypes.

Abstract: The present disclosure describes technical solutions to various technical problems facing generation of an angulated screw channel for dental implant. An improved screw channel model may be generated based on various inputs. The inputs may include dental implant parameters such as a screw channel length and a variable height. The inputs may also include dental screw parameters associated with a dental screw type, such as a screwhead diameter and a screwhead height. Using these inputs, the improved angulated screw channel model may be generated. By generating a model based on these input parameters, the resulting screw channel model allows the dental screw to be inserted and secured while reducing or minimizing a screw hole size and a screw channel volume.
