Well I am a dentist whom places implants and its confusing to me. Two of terms are registered trade marks from two different companies.
What they all are trying to deliver is a same day extractions and the insertion of screw retained fixed bridge. I say try because almost all methodologies of these Teeth in Day protocols will have a back up entirely removable denture should the doctor because of clinical situations not be able to either get all the implants in or if implants are not tight enough.
Most will have a PMA or (poly methyl acrylic ) bridge ready to deliver the day the teeth are taken out. These bridges are either milled out of like a hockey puck disk, or printed out of light cured 3D resin. An older technique was to use a regular acrylic denture that has separate acrylic teeth.
Some doctors I see advertising to deliver the PMA as the final “permanent” prosthesis. Patients really need to now what they are buying.
If you are say 50 years old and think a piece of plastic is going to last you the rest of your life think again . Problems with leaving them as the final bridge is that many times the back teeth are cantilevered or put well behind the back most implant that puts a great deal of stress on the bridge and implants its like a diving board.
Another concern is because it’s plastic, plaque sticks to it really well and the plaque will turn to foul smelling tartar over time.
A very famous dentist Dr Hahn once stated the problem with hybrid bridges is I did too many of them. He cites breakage and lack of cleans ability as biggest problem.
Another issue is tilting the implants as long as there is no bone loss things are ok. Dr Dibling has been placing implants from 1986. So I have seen the implants break from cyclic fatigue of tilted implants. Just like bending a coat hanger multiple times.
Dr Carl Misch whom is now deceased stated he was not sure why everybody wants to do immediate delivery. He stated eight cases will go well and the ninth and tenth case will fail erasing any incentive for both himself and the patient. More importantly, he felt the patient is now compromised for a due over.
Another concern of these prosthetics is just room for materials many times precious bone needs to be removed for space.
So what’s a patient to do? I say call me to make an appointment and we discuss your options. Consults are always at no charge.
