Metal ion release from metallic implants is known to occur but its extent and implications are controversial. Little is known of the metal ion release from dental implants in spite of the rapidly growing number of such implant patients. Blood levels of Ti, Al, and V were measured using an atomic absorption spectrophotometric technique preoperatively and at intervals over a 3-year period for 52 patients (17 M 35 F) each having 3 mandibular porous-surfaced endosseous dental implants. The results showed that there was no evidence of change from preoperative to long-term values for the three metals measured in the study.
