Screw-Retained vs Cement-Retained Implant Restorations: How to Choose

Screw or cement is not a preference. It is a consequence of where you put the implant.
The retention decision gets argued about as though it were a matter of taste. In practice it is largely determined at surgery — by implant angulation — and the practitioners who find it a difficult decision are usually the ones deciding it too late.
The short version
Screw-retained restorations are retrievable and eliminate cement. Cement-retained restorations are more forgiving of angulation and easier to get passive. If the screw access emerges somewhere acceptable, screw-retained is usually the better long-term choice.
Decide retention when you plan the implant position, not when the lab asks.
The case for screw-retained
What retrievability actually buys you
- Removal without destroying the restoration — for maintenance, repair or component replacement.
- No subgingival cement, and therefore no residual-cement route to peri-implant inflammation.
- Simpler management of screw loosening, which is a nuisance rather than a crisis.
- Easier long-term maintenance in patients you expect to follow for years.
Residual cement is the strongest single argument. Cement that escapes into the sulcus is difficult to detect and difficult to remove completely, and it sits in a place where the tissue response is unforgiving.
The case for cement-retained
Cement-retained restorations tolerate angulation that screw-retained ones cannot. If the implant is angled such that the screw access would emerge through an incisal edge or a buccal cusp, a cement-retained restoration solves an aesthetic problem that would otherwise require replanning.
They also achieve passive fit more easily, particularly across multiple units, because the cement layer absorbs small discrepancies that a screw would transmit as stress.
And they are simply more familiar. The workflow resembles conventional crown and bridge, which matters if you are early in your implant practice.
The angulation rule
The decision is usually made for you by where the screw access channel emerges.
| Emergence point | Implication |
|---|---|
| Cingulum or central fossa | Screw-retained is straightforward — take it |
| Slightly off-axis, still palatal/occlusal | Screw-retained with an angulated screw channel |
| Incisal edge or buccal surface | Cement-retained, or replan the implant position |
Angulated screw channel abutments have widened the range of cases that can be screw-retained, and they have made the "cement because the angle was awkward" argument much weaker than it was a decade ago.
If you do cement, cement carefully
Reducing the residual cement risk
- Keep the margin as supragingival as the aesthetics allow — deep margins are where cement hides.
- Use a replica or custom abutment analogue to extrude excess cement before seating intraorally.
- Use the minimum quantity that will retain the restoration.
- Check radiographically after cementation, accepting that radiolucent cements will not show.
Multi-unit and full-arch
For splinted and full-arch work the balance shifts decisively toward screw retention. Retrievability matters more as the restoration gets larger and more expensive, and passive fit can be verified and corrected with a verification jig rather than masked by cement.
This is one of the reasons verification jigs and implant connections are taught as their own topic rather than folded into general prosthetics.
A practical decision sequence
In order
- Plan the restoration. Decide where the crown goes.
- Plan the implant to put the screw access somewhere acceptable.
- If the access is acceptable, choose screw-retained.
- If it is not, consider an angulated screw channel before defaulting to cement.
- If cement remains the answer, keep the margin shallow and control the excess.
Note that steps one and two happen before surgery. That is the whole point.
Where this sits in the programme
Screw-retained versus cement-retained is one of the nine prosthetic topics in the Clinical Implant Program, alongside 3D prosthetic positioning, abutment solutions, verification jigs and implant protected occlusion. It is taught after the planning block, for the reason this article keeps returning to: the decision is made upstream.
