Has anyone come up with a predictable way to determine if an implant is truly integrated at the time of uncovery? I have heard of using the Ostell Mentor Device as a means of assessing implant stability, I have never had the opportunity to use this device. Are there other ways to reliably assess implant stability? I had 3 cases three in the last year that I believed the implant was truly integrated and within two months of the referring dentist restoring the implant, the patient returned with a loose failed implant. Is it possible that these implants which appeared integrated, were in fact improperly loaded and traumatic occlusal factors led to their early failure? Or was I mistaken when I assessed their osseointegration and thought they were osseointegrated but were in fact not osseointegrated? Any thoughts are greatly appreciated.
