In Vitro Effect of Surface Polishing for Reducing Bony-overgrowth (original) (raw)

Abstract

Introduction: The necessity of implant removal, chiefly within the paediatric population is widely accepted on the grounds of avoiding difficulties such as infection, adverse tissue reaction & the hindrance of bone remodeling 1 . However problems associated with device removal are commonplace & can occur mainly as a result of the complete bony-integration of a device. In clinical terms this is highly undesirable, causing increased operative time & blood loss as well as negatively influencing the healing process. Therefore, we investigated the potential of surface polishing of titanium & its alloys to reduce over-integration of a device from a cellular level, since the surface micro-topography of a material has been shown extensively to be a principle determinant of tissue integration 2 . Methods: Commercially pure titanium (cpTi), Titanium6%Niobium7%Aluminium (TAN), Titanium15%Molybdenum (Ti15Mo) & Stainless steel (Ss, negative control) were studied. Micro- rough standard surfaces o...
