摘要：
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 the first axis such that the tubular sidewall creates a non-linear channel (38, 138), the apical portion being sized and shaped to form a friction fit with the base part, wherein, when the base part is connected to the angled part, a closed channel (60, 160) is formed extending from the apical end of the base part to the coronal end of the angled part, the first axis of the apical portion of the angled part being coaxial to the longitudinal axis of the base part and the anti-rotation section of the base part being exposed on a surface of the base part.
