Effect of different surface treatments on prefabricated fiber posts: a literature review

Rita Eid Najib Abou Hamra Danielle Hakim Maha Ghotmi Abstract This literature review summarizes the recent research on fiber posts regarding surface treatment to improve their adhesive properties. Actual methods to treat the surface relied on chemical and/or micro-mechanical techniques. The majority of data was based on in vitro studies that investigated different chairside post surface treatments for enhancing and/or modifying the surface available for bonding. The tests used were microtensile and push out bond strength in combination with SEM analysis. Few studies included aging procedures and 3 point bending test to evaluate mechanical properties of the treated posts. According to the reviewed in vitro studies, surface conditioning improves fiber posts bonding properties and leads to a good bond strength between the post and the restorative materials. Results are promising especially regarding some new acidic t...
