dc.description.abstract | Evaluate the quality of finishing and degree of contamination before and after handling and
surface treatment of titanium (Ti) orthodontic mini-implants (OMIs). A scanning electron microscope
(SEM) study on ninety-six titanium OMIs was done. Energy-Dispersive X-ray Analysis (EDX)
identified the present particles on manufactured OMIs surfaces. Then, OMIs were manipulated with
gauze (dry sterile, soaked in chlorhexidine) and gloves (latex, nitrile) to evaluate the contamination
of these handling materials. Finally, OMIs underwent surface treatments and were placed in bone to
observe the contaminants they released. Roughness (Ra) and wettability with contact angle parameter
(CA) were measured on these treated OMIs. Machined OMIs presented surface irregularities and
were contaminated with manufacturing-process particles (carbon, plastic Polyvinyl Chloride PVC,
aluminum). Hand-manipulated OMIs were also contaminated by the handling materials. OMIs
surface characteristics were as follows: acid-etched (Ra 1.3 m, CA 66 ), machined (Ra 0.3 m,
CA 68 ), SB (Ra 3.3 m, CA 78 ), and SBAO (Ra 3.1 m, CA 92 ). Bone was contaminated
by OMIs surface defects and extra particles. Manufactured OMIs have surface contaminants that
increase with clinical handling. Surface treatments (SBAO, a combination of sandblasting and anodic
oxidation) increase the roughness and contact angle, which play an important role in osseointegration.
Surface-treated OMIs leave titanium particles in the bone during their insertion-removal. The use
of a gauze soaked in chlorhexidine is recommended when handling OMIs. Further investigations
would be interesting to study more variables and confirm the present results. | es |
