How to Choose the Right Temporary Abutment
- PMMA/POM Plastic Abutments — Machinable plastic temporary abutments can be freely shaped, shortened, and contoured chairside with a bur to create an anatomically correct emergence profile for the provisional crown, then relined or bonded to a coping.
- Titanium Temporary Abutments — Titanium provisional abutments offer greater mechanical strength than plastic during the provisional phase, useful when the provisional restoration must withstand functional load for an extended healing period.
- Immediate vs Delayed Provisionalisation — Immediate provisionalisation at the time of implant placement requires the temporary abutment to be seated at a controlled, reduced torque to avoid disturbing primary stability during osseointegration; delayed provisionalisation allows standard torque values once integration is confirmed.
- Occlusal Clearance — Confirm adequate occlusal clearance before contouring the provisional crown over a temporary abutment, since inadequate reduction is a common cause of provisional fracture under functional load.
- Chairside Modifiability — Select a plastic temporary abutment when the emergence profile is expected to be adjusted over multiple visits to guide soft tissue contour, since plastic can be added to or reduced more easily than titanium chairside.

Frequently Asked Questions
Should I choose a plastic or titanium temporary abutment for a provisional crown?
Should I choose a plastic or titanium temporary abutment for a provisional crown?
Plastic (PMMA/POM) temporary abutments are preferred when the emergence profile needs to be shaped and adjusted chairside over multiple visits to guide soft tissue healing. Titanium temporary abutments are preferred when the provisional restoration must withstand functional load over an extended healing period with less risk of mechanical fatigue.
What torque should be used when seating a temporary abutment for immediate provisionalisation?
What torque should be used when seating a temporary abutment for immediate provisionalisation?
For immediate provisionalisation at the time of implant placement, the temporary abutment is generally seated at a reduced, controlled torque well below the implant's insertion torque, to avoid disturbing primary stability during the early osseointegration window. Confirm the specific value against the implant manufacturer's protocol.
Can a plastic temporary abutment be relined or added to chairside?
Can a plastic temporary abutment be relined or added to chairside?
Yes. PMMA and POM plastic temporary abutments can be built up with flowable or self-cure acrylic and recontoured chairside with a bur, which is precisely why they are favoured for shaping the provisional crown's emergence profile over the course of soft tissue healing.
How long can a temporary abutment remain in function before it must be replaced?
How long can a temporary abutment remain in function before it must be replaced?
There is no universal fixed duration; the temporary abutment remains until the implant is confirmed osseointegrated and soft tissue contour has stabilised, at which point it is removed and replaced with the definitive abutment for the final restoration. This period commonly spans several weeks to a few months depending on the case.
