Has anybody tried to remove cemented crowns or bridges with a pneumatic handpiece? If you used a provisional cement, it should be relatively easy to break the cement layer and deliver the crown or bridge without much force.
I personally have never tried this and am worried about damaging or loosening the dental implant. When I have a problem, I cut off the crown or bridge and redo it. We are curious about others experiences with pneumatic handpieces as it relates to implant dentistry. Post your comments below.
works very well, but, start at low force and vary where you apply the force from ie: B, L, D, L, B,etc. Do not increase the force too quickly and be very careful at higher forces. If the restoration does not release after a few trys cut it off or stop and try again another day often the second or third try will work after allowing some time to pass.
I have a pneumatic crown remover by Dentcorp. It is the best investment I’ve made. It easily taps off loose bridges on teeth or implants. There is a special tip that fits under the connectors and a few simple taps and the bridge is loose. It is a little more difficult with crowns because it is more difficult to find a horizontal surface to engage with the remover. Sometimes I’ll cut a small slot in the lingual of the crown to gain a purchase point. I have even used the remover when the abutment screw is loose and have been able to remove the crown without breaking the screw. I use different strengths of cement depending on how much retention my abutment has. I’ll use (in increasing strength) temrex, tempbond, tempocem then temrex NE. If the remover doesn’t dislodge the restoration (never happened on a bridge, rarely happens with a single unit) then you’ll need to cut the crown off or drill an access hole to find the screw. If an implant deintegrates with the remover, it was probably poorly integrated anyway. Dentcorp has a 1-800 number to order the unit. You’ll wonder how you lived without it!!
