Alloy Implants

Dr. Charlton asks:
I am concerned about placing pure titanium dental implants. The alloy implants appear to be stronger.

In fact, I have seen dental implant fixtures fracture. I have discussed this question with one major implant company and they assure me that there is no significant difference in dental implant fixture strength and resistance to fracture when considering alloy or pure titanium. Incidentally, they have to use pure titanium because their proprietary surface coating will not bond to the alloy. What is the track record out there with those of you who have used both pure titanium and alloy dental implants? Is there really no difference? Thanks.
