Connections
Implant-abutment connection types — conical, Morse taper, internal and external hex, and proprietary designs — and why the connection matters.

- CAMLOG Tube-in-Tube CAMLOG’s implant-abutment connection: a butt-joint cylindrical fit in which three grooves in the implant receive three matching cams on the abutment.
- Conical (Morse taper) connection An internal connection in which the abutment seats into a tapered bore in the implant, so that friction between the two conical surfaces carries much of the joint’s stability rather than the screw alone.
- External hexagon An implant-abutment connection in which a hexagonal boss projects above the implant platform and engages a matching recess in the abutment, the two parts being held together by a screw.
- Internal hexagon An implant-abutment connection in which the hexagonal anti-rotation feature sits inside the implant body, so the abutment drops into a recess below the platform rather than over a boss above it.
- Internal octagon An internal connection whose anti-rotation feature is an eight-sided recess inside the implant, used to reposition prosthetic parts in a repeatable orientation.
- Internal tri-channel An internal connection whose anti-rotation feature is three channels or lobes arranged around the implant bore, rather than a hexagon or an octagon.
- Neodent Grand Morse Neodent’s Morse taper implant-abutment connection, stated by the manufacturer to have a 16 degree full angle and to incorporate platform switching.
- Nobel Biocare Conical Connection Nobel Biocare’s internal conical implant-abutment connection, used across the NobelActive, NobelParallel CC and NobelReplace CC implant lines.
- Straumann CrossFit Straumann’s internal connection for its Bone Level implant lines: a 15 degree conical-cylindrical friction fit with four internal grooves.
- Straumann synOcta Straumann’s internal Morse taper connection for its tissue-level Standard and Standard Plus implants, combining an 8 degree cone with an internal octagon.
- Straumann TorcFit Straumann’s connection for its BLX and TLX implant systems: a 7 degree conical seat combined with a six-position torx-style index.
