Assessment of Metal Ions Levels in Blood of Dental Implant Patients

BACKGROUND: Dental implants use has significantly increased and the concentration of metal ions into blood may have detrimental effect of human body. The present study aimed to determine metal ions levels in blood of dental implants patients. MATERIALS AND METHODS: 48 patients scheduled for dental implant surgery was assessed for measurement of titanium and aluminum pre-operatively and post-operatively at 6 weeks, 3 months, 6 months, and 1 year. RESULTS: Out of 48 patients, males were 22 (45.8%), and females were 26 (54.2%). The mean ± SD titanium metal levels in blood pre-operatively was 2.34 ± 0.47 mg/dl, at 6 weeks was 2.35 ± 0.48 mg/dl, at 3 months was 2.37 ± 0.52 mg/dl, at 6 months was 2.37 ± 0.42 mg/dl, and at 1 year was 2.38 ± 0.51 mg/dl. A non-significant difference was seen (P > 0.05). The mean ± SD aluminum metal levels in blood pre-operatively was 4.4 ± 0.12 mg/dl, at 6 weeks was 4.45 ± 0.14 mg/dl, at 3 months was 4.7 ± 0.13 mg/dl, at 6 months was 4.7 ± 0.21 mg/dl, and at 1 year was 4.8 ± 0.17 mg/dl. A non-significant difference was seen (P > 0.05). CONCLUSION: A non- significant increase in titanium and aluminum ions level in blood of patients receiving dental implants was observed.
