Abstract:
The titanium exfoliation level during dental implant installation has not yet been available. The present
study aims to confirm the presence of titanium exfoliation in different implant surfaces throughout the
installation and identify the association between insertion torque and surface abrasion. Three different
implant surfaces were assigned to low and high insertion torque groups. The implants were installed
into porcine bone blocks. Then, the surrounding bone at the ostomy site was analysed for the titanium
exfoliation using an inductively coupled plasma mass spectrometry. The low and high insertion
torques were 30 Ncm and 58 Ncm, respectively. The average titanium content from all samples was
4.9 ± 2.7 μg. Anodised implant released significantly less titanium compared to others (p < 0.05).
All implants released titanium indifferently compared to low and high insertion torques (p > 0.05).
Within the limitation of the present study, anodised implant released the least amount of titanium
exfoliation. The insertion torque was not associated with titanium exfoliation.
