The effect of using Al2O3 and TiO2 in sandblasting of titanium dental implants

The effect of Al 2 O 3 with respect to TiO 2 as abrasive for the osseointegration of dental implants has been questioned. The aim has been to clarify the advantages or disadvantages of mechanical and biological response. The implants studied were as-received with acid etching and sandblasted with Ti...

Description
Summary:The effect of Al 2 O 3 with respect to TiO 2 as abrasive for the osseointegration of dental implants has been questioned. The aim has been to clarify the advantages or disadvantages of mechanical and biological response. The implants studied were as-received with acid etching and sandblasted with TiO 2  and with Al 2 O 3  with posterior acid etching. Roughness, microhardness, residual stresses and fatigue were determined. In vivo tests were realized in minipigs. The percentage of bone index contact (BIC) after 2 and 6 weeks of implantation was determined histometric evaluation. Results showed that the roughness of the Al 2 O 3 treated implants was 2.54 respect to 0.80 μm for TiO 2 , microhardness were 370 and 241 HVN and compressive residual stresses of − 2450 and − 78.3 MPa, respectively. These compressive stresses justify the higher fatigue strength of the Al 2 O 3 sandblasted samples. BIC values after 6 weeks were 63% compared to 38% for TiO 2 . Graphical abstract
