Abstract: A torque limiting device for use with a dental drive tool including a housing defining a rotation axis and having a bore concentric with the rotation axis and a torque limiting insert. The housing has a recess for housing at least part of the torque limiting insert. The torque limiting insert includes a fixing region held within the housing and a spring region extending from the fixing region and including a locking catch protruding into the bore. The locking catch is aligned with the recess so it can be moved radially outwards into the recess in to a disengaged position. The locking catch is arranged to engage with the dental drive tool when the tool is introduced in the bore to transmit a torque applied to the housing and to deflect into the disengaged position against the force of the spring region when a predefined torque limit is reached.

Abstract: A dental implant system including a dental implant (1) and an associated implant analog (50), the implant extending along a longitudinal axis (L1) from an apical end (101) to a coronal end (102) and having an external surface for anchoring and osseointegrating in bone, a coronal end portion (105) having abutment connection geometry for cooperating with an abutment which can be seated in one or more defined positions on the implant, the abutment connection geometry having a coronally facing abutment contact surface (128) which extends around the full circumference of the implant, and in use directly contacts the abutment and provides a stop defining the axial location of the abutment relative to the implant, the coronal end portion further having a coronally facing prosthesis contact surface (129) located radially beyond the abutment contact surface, the prosthesis contact surface being a continuous surface extending around the full circumference of the implant.

Abstract: A two part modelling aid for connection to a dental implant component including a hollow base part and a hollow angled part, each including a tubular side wall extending between apical and coronal ends. The base part side wall includes an anti-rotation section including a non-circular symmetric cross-section in a plane perpendicular to a longitudinal axis of the base part. The angled part side wall forms an apical portion that extends along a first axis and is sized and shaped to form a friction fit with the base part, and a coronal portion extending along a second axis non-coaxial to the first axis. When connected, a closed channel is formed extending from the base part to the angled part, and the first axis of the apical portion is coaxial to the longitudinal axis of the base part and the anti-rotation section is exposed on a base part surface.

Abstract: A dental implant system including a dental implant (1) and an associated implant analog (50), the implant extending along a longitudinal axis (LI) from an apical end (101) to a coronal end (102) and having an external surface for anchoring and osseointegrating in bone, a coronal end portion (105) having abutment connection geometry for cooperating with an abutment which can be seated in one or more defined positions on the implant, the abutment connection geometry having a coronally facing abutment contact surface (128) which extends around the full circumference of the implant, and in use directly contacts the abutment and provides a stop defining the axial location of the abutment relative to the implant, the coronal end portion further having a coronally facing prosthesis contact surface (129) located radially beyond the abutment contact surface, the prosthesis contact surface being a continuous surface extending around the full circumference of the implant. The associated analog (50) has an external surface comprising an anti-rotation section (53) having a non-circular symmetric cross-section in a plane perpendicular to the longitudinal axis for non-rotational fixation in a dental model, an analog head (55) located at the coronal end of the analog, the head having abutment connection geometry for cooperating with the abutment so that it is seatable in the same one or more defined positions on the analog as on the implant. The abutment contact surface of the analog has the same longitudinal cross-section and radial location relative to its longitudinal axis as at least a portion of the abutment contact surface of the implant about the entire circumference of the analog, such that the abutment contact surface of the analog matches at least a part of the abutment contact surface of the implant about its entire circumference, and the prosthesis contact surface of the analog has the same longitudinal cross-section and location relative to its abutment contact surface and longitudinal axis as one or more portion of the prosthesis contact surface of the implant, such that the prosthesis contact surface of the analog matches one or more part of the prosthesis contact surface of the implant. In comparison to the prosthesis contact surface of the implant, the prosthesis contact surface of the analog is discontinuous in at least the circumferential and/or radial direction.
