Title
Cemented fixation with PMMA or Bis-GMA resin hydroxyapatite cement: effect of implant surface roughness
Abstract

Implant surface roughness is an important parameter governing the overall mechanical properties at the implant–cement interface. This study investigated the influence of surface roughness using polymethylmethcrylate (PMMA) and a Bisphenol-a-glycidylmethacyrlate resin-hydroxyapatite cement (CAP). Mechanical fixation at the implant–cement interface was evaluated in vitro using static shear and fatigue loading with cobalt chrome alloy (CoCr) dowels with different surface roughness preparations. Increasing surface roughness improved the mechanical properties at the implant–cement interface for both types of cement. CAP cement fixation was superior to PMMA under static and dynamic loading.
