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 two part modelling aid (1, 100) for connection to a dental implant component (200), the modelling aid comprising a hollow base part (10, 110) comprising an open apical end (14, 114), an open coronal end (16, 116) and a tubular side wall (12, 112) extending from the apical to coronal end along a linear longitudinal axis (LB), the side wall having an interior and an exterior surface, one of said surfaces comprising an anti-rotation section (18, 118) having a non-circular symmetric cross-section in a plane perpendicular to the longitudinal axis, and a hollow angled part (30, 30) comprising an open apical end (34, 134), an open coronal end (36, 136) and a tubular side wall (32, 132) extending between the apical end and coronal end and having an interior and exterior surface, the tubular side wall forming an apical portion (35, 135) of the angled part extending along a first linear axis (L1), and a coronal portion (37, 137) of the angled part extending along a second axis, the second axis being non-coaxial to th
