Implant surgery on blood thinners
Perioperative management of anticoagulants and antiplatelets. The modern default for routine oral surgery is do not interrupt — control bleeding locally — because thrombotic risk from stopping usually outweighs bleeding risk.
Use: Pre-surgical medication check
Default: Continue + local hemostasis
Never: Bridge DOACs / stop alone
01 — Drug Groups
Identify the agent first
Management differs by class. For most single/simple extractions and routine implant placement, therapeutic anticoagulation can continue with local measures. Any decision to interrupt must be made with the prescriber, weighing thrombotic risk.
Group
Vitamin K antagonist
- Warfarin
- Check recent INR (within 24–72 h)
- Continue if INR < 4.0
- Do not bridge for routine surgery
Group
DOACs
- Apixaban, rivaroxaban, dabigatran, edoxaban
- No INR monitoring
- Usually continue; never bridge
- Consider morning-dose timing per prescriber
Group
Antiplatelets
- Aspirin, clopidogrel, dual (DAPT)
- Do not stop for routine dental surgery
- DAPT post-stent: never interrupt alone
- Local hemostasis suffices
02 — Decision Pathway
Interactive management selector
Match the agent and the bleeding complexity of the planned procedure. Escalate (defer/refer) only for high thrombotic risk plus extensive surgery — and always in concert with the prescribing physician.
Tap the patient's medication group.
Step 1 — Which agent is the patient taking?
WARFARIN
Vitamin K antagonist
INR-monitored.
DOAC
Apixaban / rivaroxaban / etc.
Fixed dose, no monitoring.
ANTIPLATELET
Aspirin / clopidogrel / DAPT
Often post-cardiac stent.
HIGH BLEED + EXTENSIVE
Multiple agents / major augmentation
Large flap, grafting, comorbidity.

03 — Local Hemostasis
The toolkit that makes "continue" safe
Continuing therapy is only appropriate when robust local hemostasis is planned and available.
| Measure | Use |
|---|
| Atraumatic technique | Minimize flap and trauma; primary closure where possible |
| Sutures | Stabilize the clot and approximate tissue |
| Oxidized cellulose / collagen / gelatin | Pack the socket / osteotomy |
| Tranexamic acid | Mouthrinse or gauze soak per local policy |
| Pressure pack | Firm bite on damp gauze; clear post-op instructions |
| Schedule timing | Morning, early week appointments to manage any rebleed |
