The number of teeth you get is 10-12. The number depends on how far back we can place the most rear two implants. This means you will have the 4 incisors, a canine then 1-2 premolars and a molar. Either number is ample for chewing purposes and certainly does not leave a visible gap behind your last teeth in your smile. The reason for 10 -12 is that there is anatomy that may limit how far back we can get the implants and a 3D CT scan is the only way to know exactly how many teeth you can have with certainty. This treatment concept cantilevers the back molar plus 1 or 2 premolars off the back implant to get as many chewing teeth as possible. The limitation is the force that is generated on the back implant by the length of the cantilever when you chew.
