摘要：
A dental implant system comprising a dental implant (1) and an associated implant analog (50), the implant extending along a longitudinal axis (U) from an apical end (101) to a coronal end (102) and comprising an external surface for anchoring and osseointegrating in bone, a coronal end portion (105) having abutment connection geometry for cooperating with an abutment such that the abutment can be seated in one or more defined position on the implant, the abutment connection geometry comprising a coronally facing abutment contact surface (128) which extends around the full circumference of the implant, and which 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 comprising 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) extending along a longitudinal axis (L) from an apical end (51 ) to a coronal end (52) and comprising 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, said head comprising abutment connection geometry for cooperating with an abutment such that the abutment can be seated in the same one or more defined position on the analog as it can on the implant, the abutment connection geometry comprising a coronally facing abutment contact surface (58), which in use directly contacts the abutment and provides a stop defining the axial location of the abutment relative to the analog, the head further comprising a coronally facing prosthesis contact surface (60) located radially beyond the abutment contact surface, wherein the abutment contact surfac
