Dental component with an interface

A dental component including:

• a coronal end, an apical end, and
• an interface configured to assemble to an other dental component, the interface comprising:
• a plurality of protrusions, each protrusion of the plurality of protrusions comprising:
• at least two indexing sections configured to rotationally lock the dental component to the other dental component, and
• at least one guiding section configured to guide the other dental component about a longitudinal axis towards the next indexing section, the longitudinal axis extending between the coronal end and the apical end,
• wherein the at least one guiding section and the at least two indexing sections alternate about the longitudinal axis, the at least one guiding section and the at least two indexing sections forming an undulating surface about the longitudinal axis of the dental component, the undulating surface undulating along a longitudinal direction,
• wherein each of the at least one guiding section includes an apically facing or a coronally facing guiding surface,
• wherein each of the at least two indexing sections comprises a surface parallel to the longitudinal axis,
• wherein each indexing section of the at least two indexing sections is defined between two boundary lines, wherein the two boundary lines define two boundary points along a profile of the indexing section and a tangent to any one of the two boundary points has a larger absolute slope than any tangent to a profile of the at least one guiding section,
• a mating surface extending between the plurality of protrusions,
• wherein the mating surface is configured to transfer forces in a direction of the longitudinal axis of the dental component, the mating surface facing in a same direction as the guiding surface and extending about the longitudinal axis, and
• at least one radially facing support surface, the at least one radially facing support surface being located radially inwards in relation to the at least two indexing sections and the at least one guiding section, the at least one radially facing support surface forming an extremity of the interface, the at least one radially facing support surface comprising at least a portion of a cylindrical surface extending between the plurality of protrusions.

A dental assembly for mounting a prosthesis, the dental assembly comprising:

• a coronal dental component;
• and
• an apical dental component,
• wherein each of the coronal dental component and the apical dental component comprises:
• a coronal end, an apical end, and
• an interface configured to assemble to the other dental component, the interface comprising:
• a plurality of protrusions, each protrusion of the plurality of protrusions comprising:
• at least two indexing sections configured to rotationally lock the dental component to the other dental component, and
• at least one guiding section configured to guide the other dental component about a longitudinal axis towards the next indexing section, the longitudinal axis extending between the coronal end and the apical end,
• wherein the at least one guiding section and the at least two indexing sections alternate about the longitudinal axis, the at least one guiding section and the at least two indexing sections forming an undulating surface about the longitudinal axis of the dental component, the undulating surface undulating along a longitudinal direction,
• wherein each of the at least one guiding section includes an apically facing or a coronally facing guiding surface,
• wherein each of the at least two indexing sections comprises a surface parallel to the longitudinal axis,
• a mating surface extending between the plurality of protrusions,
• wherein the mating surface is configured to transfer forces in a direction of the longitudinal axis of the dental component, the mating surface facing in a same direction as the guiding surface and extending about the longitudinal axis, and
• at least one radially facing support surface, the at least one radially facing support surface being located radially inwards in relation to the at least two indexing sections and the at least one guiding section, the at least one radially facing support surface forming an extremity of the interface, the at least one radially facing support surface comprising at least a portion of a cylindrical surface extending between the plurality of protrusions,
• wherein at least a part of the interface of the coronal dental component faces apically, and
• wherein at least a part of the interface of the apical dental component faces coronally.
