evaluated in an in vivo study, using mechanical testing of the bone – implant interface strengthand histomorphometric analyses. The results of the mechanical testing indicate that the MAOand SLA surface treatments have potential to enhance peri-implant bone healing; however, astatistically significant difference in the performance of the SLA and MAO surface treatmentswas not shown.References1.
