How to Care for Your BFC3 Impression Gun Between Patients

Keep your cordless BFC3 impression gun delivering consistent, drip-free impressions with this step-by-step between-patient care routine, from purge to storage.
Quick answer
After each patient, purge a small amount of material, wipe the mixing tip and nozzle with a manufacturer-approved cleaner, and inspect the cartridge seat for set material. Then store the gun with a fresh tip or cap to prevent drips and clogs. This five-minute routine keeps the BFC3 Powered Impression Gun's adjustable flow and anti-drip feature working reliably.
Why between-patient care matters for the BFC3
The BFC3 is a cordless impression gun with an adjustable flow rate and an anti-drip feature. Those features depend on clean, unobstructed material paths. If set impression material is allowed to cure inside the mixing tip or nozzle, the next patient's impression can be short, distorted, or delivered with inconsistent flow. A quick purge and wipe after every patient prevents that buildup and keeps the gun ready for the next case.
Supplies to keep at the operatory
Set up a small care kit so cleaning is never skipped: manufacturer-approved cleaning wipes or a mild detergent solution, a soft-bristle brush, disposable gloves, a small bin for used tips, and spare mixing tips. Keep the BFC3's charging base or storage spot nearby so the gun never sits with a loaded, set tip.
What not to do
Do not immerse the BFC3 in water or run it through an autoclave unless the manufacturer's instructions specifically allow it. Do not use sharp instruments to dig out set material, as they can scratch the nozzle or damage the anti-drip mechanism. Avoid leaving a loaded cartridge in the gun overnight; the material can cure and block the flow path.
Between-patient care steps
- Purge and remove the used mixing tip: After the impression is seated, purge a small amount of material to clear the tip, then twist off the mixing tip and dispose of it. Common mistake: leaving the tip on, which lets material cure and block the nozzle. Checkpoint: material should flow freely during purge; if not, the tip may already be partially set.
- Wipe the nozzle and cartridge seat: Use a manufacturer-approved wipe or mild detergent on a soft cloth to remove uncured material from the nozzle, cartridge seat, and trigger area. Do not use solvents that could degrade plastic or seals. Checkpoint: no tacky residue should remain on the nozzle or seat.
- Inspect for set material and damage: Look closely at the nozzle opening and the cartridge seat for any cured material. If you see set material, remove it gently with a soft-bristle brush or plastic pick. Check the anti-drip mechanism for smooth movement. Checkpoint: the nozzle should be clear and the anti-drip seal should sit flush.
- Store with a fresh tip or cap: If the gun will be idle, fit a new mixing tip or the manufacturer's cap to keep the nozzle clean and prevent drips. Remove the cartridge if the material will not be used within the working time. Checkpoint: the gun should be stored upright or on its stand, not lying on the nozzle.
- Charge or check power for the next patient: Place the cordless BFC3 on its charging base or verify battery level so it is ready for the next procedure. A depleted battery mid-impression can force a remake. Next step: log the cleaning and note any flow issues for troubleshooting.
Product facts
- BFC3™ Powered Impression Gun-Dental Impression Material Delivery System: Ultradent's first cordless impression gun with adjustable flow rate and an innovative anti-drip feature. Cordless freedom and flow control make between-patient cleaning easier, but the anti-drip feature relies on a clean nozzle to seal properly.
