Device for determining a suitable angulation of an abutment for a dental implant, and arrangement comprising such a device

An assembly for selecting one of a plurality of predefined abutments having different angulation angles, the assembly comprising:

• a device for determining an abutment angulation for a dental implant, the device comprising:
• a housing,
• a projection fastened to the outside of the housing, which is insertable into an internal hole of the dental implant,
• a rotary body rotatable in the housing relative to the projection,
• a rod-shaped indicator connected to the rotary body and extending away therefrom such that a majority of a length of the rod-shaped indicator is disposed outside the housing, and
• a locking device for releasably coupling the rotary body to the housing,
• wherein the rotary body is rotatable to allow the rod-shaped indicator to pivot among a plurality of different angular positions relative to the projection, wherein each of the plurality of different angular positions of the rod-shaped indicator is determined by the angle between a longitudinal axis of the rod-shaped indicator and a longitudinal axis of the projection, and wherein the rod-shaped indicator may be locked in any one of the plurality of different angular positions by the locking device coupling the rotary body to the housing;
• an indicator device, which comprises a receiving opening for accommodating the projection of the device, the receiving opening having a longitudinal axis, and
• a display scale disposed laterally from the receiving opening and extending in a plane disposed parallel to the longitudinal axis of the receiving opening, the display scale including a plurality of marked sectors corresponding to the plurality of predefined abutments, respectively, and wherein the location of the rod-shaped indicator relative to the marked sectors indicates the one of the plurality of predefined abutments that should be selected.
