With the all on four implants will I be able to have more than 24 teeth?

Question

I've had the implants and am still in my healing denture. When I asked why I don't have back teeth I was told I would with my permanent bridge (s). Now my dentist is saying that I won't.

Jose Valenzuela, DDS · Answer

This depends on the position of the implants as well as force factors, length and width of implants used and cantilever. Sometimes only 10-12 are placed on the lower.

Juan C. Arroyo, DMD · Answer

Hi and thank you for your question. Typically the All on Four procedure will extend a prosthesis to the area of the first molar, this means 12 upper teeth and 12 lower teeth. It could be possible to extend the prosthesis if the is more implant support in the back, this could be accomplished with sinus grafting.
Good luck to you,

The location of the back implants have a major role for how far the teeth can be spread in order to have 24 or 28 tooth. 24 teeth should give very good chewing abilities without risking adding more teeth in the back that might affect the strength of the denture and the implants by cantilever effect.

Tarun Giroti, MDS · Answer

Trust me you will look good and eat well with 24 teeth. You don't need all the teeth till the third molars to eat well. 90 percent of our chewing is till the first molars and the second and the third molars play a minor role in chewing.  So please don't worry about not having all the 32 teeth back.

John Paul Gallardo, DDS · Answer

Extending teeth beyond first molars is determined by where the posterior implants are going to be placed. Typically, All on 4 patients have poor bone availability in the molar areas, so implants have to be intentionally placed at mechanical inclinations. What your dentist is most likely trying to avoid is a long cantilever which can overload either the implants themselves, or the prosthesis leading to fracture and ultimate failure.

Ivan Chicchon, DDS · Answer

How Many teeth you receive depends on the amount of bone that you have in your jaws. If there is plenty of bone for dental implants, then it is possible to have up to your second molars. However, if it there is a limited amount of bone it may be necessary to limit the number of teeth to only have one molar. This is done to minimize adverse stresses on the implants and the prosthesis.

Michael Mazaheri, DDS · Answer

There are several factors that dictate the position of teeth and the number of teeth restored on the final all on four prosthesis. Sometimes lack of bone and clearance of the opposing arch will not allow ideal implant placement therefore limiting the extent of the prosthesis. Please post x-rays and pictures as it is difficult to comment on your particular situation without seeing the conditions.Dr. Mazaheri

yes you can , as long as you have great support, also you will need to have good analysis of phonetics,due to different factors that might interfere.
