The subject of implant diameters always brings with it some level of controversy. A recent study investigated the effect of implant diameter on fatigue strength using static and cyclic load test, by comparing four different implant systems, ranging from 2.3 to 4.0. The conclusion:
Implant diameter has an effect on the ability to withstand both static and cyclic loads within Dentium implant systems, The ultimate failure load (UFLs) and fatigue cycles decreased as the implants diameter became smaller.
This, of course, is only one study, but we are curious if anyone has actually measured the failure rate of various implant diameters in their practice? Does the failure rate increase as the diameter of implants decreases?
