Implant Neck
The coronal portion of the implant body adjacent to the crestal bone and soft-tissue interface, often featuring a smooth or micro-textured surface to manage crestal bone levels.
Full Definition
The implant neck (also called the collar or cervical region) is the transitional zone between the threaded endosseous portion of the implant and the prosthetic connection interface above. Its surface treatment—ranging from polished machined metal to micro-grooved or rough surfaces—is a design variable that influences crestal bone behaviour and the extent of soft-tissue attachment. A machined (smooth) neck was historically intended to limit bone-to-implant contact in the transmucosal region, while modern microstructured necks aim to promote bone maintenance at the crest. Editors should not conflate 'implant neck' with 'transmucosal collar,' which is an anatomical/functional region, or with 'abutment,' which is a separate restorative component.
Usage
Usage note: The terms 'neck,' 'collar,' and 'shoulder' are used variably by different implant manufacturers; when editing manufacturer documentation, adopt the brand's preferred terminology consistently.
