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.

Two-part modelling aid

A dental implant system including a dental implant () and an associated implant analog (), the implant extending along a longitudinal axis (L) from an apical end () to a coronal end () and having an external surface for anchoring and osseointegrating in bone, a coronal end portion () 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 () 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 () located radially beyond the abutment contact surface, the prosthesis contact surface being a continuous surface extending around the full circumference of the implant.

Implant analog

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.
