摘要:
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
