Are implants are more predictable than teeth?
Don't get me wrong... I think having the ability to treatment plan implant restorations has added a great tool to most dentist's tool box, but sometimes salvageable teeth are extracted to facilitate implant placement and a definitive full arch fixed restoration. I myself do this when the bone is needed to place an implant that will serve as an abutment for a multi implant treatment plan. Sometimes teeth do get in the way. That being said, there seems to be an increasing tendency for dentists to advocate the removal of all remaining teeth to fabricate a "hybrid" full arch implant restoration. There is a nasty joke going around about all on 4 implant cases ... they are great unless one of the implants doesn't take or last long and then the entire case can be considered a failure since there is no such thing as an all on three case. Also many patients are encouraged to have expensive full arch implant treatment cases without empasizing the need for the cleans...
