What is its purpose?
It connects the implant body to the prosthetic abutment.
← All explanationsImplant–abutment connection
How are a dental implant and its abutment connected?
The implant–abutment connection is the technical interface between the implant anchored in bone and the abutment supporting the crown or other restoration. It may be internal or external, conical or another shape. In screw-retained constructions, the fit and screw preload work together. Not every connection can be combined with every component.

Identifying the interface
The implant is anchored in bone. Above it, the abutment connects the implant body to the restoration. Its contact surface must match the intended implant connection.
The screw creates preload
Correct tightening of the connecting screw creates preload that holds the components together. Fit, screw design and loading influence mechanical stability.
Checking changes
A moving crown, unusual sounds or a changed bite should be examined. Sensation alone cannot reliably establish whether looseness comes from a screw, the crown or the implant itself.

Is shape the only factor?
No. Fit, the screw, preload and loading also matter.
What should happen if it loosens?
Professional assessment, without attempts to repair or tighten it yourself.

Often confused
Often confused: implant and abutment
The implant is anchored in bone. The abutment is the connecting component above it. A loose abutment connection does not automatically mean that the implant is loose in the bone.
Quick answers
Is a conical connection always better?
A particular shape may show mechanical advantages in the laboratory. Laboratory comparisons do not establish a universal clinical ranking of all systems. Planning, components and loading still matter.
Can any abutment be used?
No. Compatibility with the implant system and planned restoration must be established. Components that look alike are not automatically interchangeable.
Should I tighten a loose implant crown myself?
No. The cause needs professional assessment using suitable components and a controlled approach. Arrange a prompt examination and avoid loading the loose restoration until then.
At the practice
For the appointment
You can bring this question to your appointment:
Which connection system is documented for my implant, and which changes should I watch for?
If an implant restoration is being planned or starts to feel different, you can discuss its components, documentation and review.

- Preload
- Tension generated when a screw is tightened, clamping the connected components together.
- Anti-rotation feature
- A design feature intended to limit unwanted rotation of connected parts.
Make the distinction
The implant is anchored in bone. The abutment is the connecting component above it. A loose abutment connection does not automatically mean that the implant is loose in the bone.
