Osseointegration of zirconia implants compared with titanium: an in vivo study

Abstract

Background: Titanium and titanium alloys are widely used for fabrication of dental implants. Since the material composition and the surface topography of a biomaterial play a fundamental role in osseointegration, various chemical and physical surface modifications have been developed to improve osseous healing. Zirconia-based implants were introduced into dental implantology as an altenative to titanium implants. Zirconia seems to be a suitable implant material because of its tooth-like colour, its mechanical properties and its biocompatibility. As the osseointegration of zirconia implants has not been extensively investigated, the aim of this study was to compare the osseous healing of zirconia implants with titanium implants which have a roughened surface but otherwise similar implant geometries.

Assessment of the primary stability of root analog zirconia implants designed using cone beam computed tomography software by means of the Periotest® device: An ex vivo study. A preliminary report

“…Its excellent biocompatibility is similar to that of titanium implants, which has been demonstrated in several animal investigations. 30 In the presented study, RAZI was modified according to the Pirker's protocol. 28 The macroretentions were limited only to the interdental space (mesial and distal part of the root) for better primary stability and osseointegration.…”

Numerical simulation of the fracture process in ceramic FPD frameworks caused by oblique loading

“…Their advantages include high biocompatibility (Depprich et al, 2008), good esthetic appearance (Ghazal et al, 2008), low solubility and low thermal conductivity (Chai et al, 2007). Among the crucial problems for ceramics, however, are low fracture resistance and brittleness and, consequently, no or little apparent plastic deformation can occur before fracture (Munz and Fett, 1999 j o u r n a l o f t h e m e c h a n i c a l b e h a v i o r o f b i o m e d i c a l m a t e r i a l s 5 0 ( 2 0 1 5 ) 2 0 6 -2 1 4…”

Zirconia a Bio-inert Implant Material

“…Twenty-four screws type zirconia with surface modifications and twenty four titanium implants of same shape and size inserted in the tibia of minipigs a study done by Rita Depprich et al (20). The results showed that animals were normal and showed no signs of infection.…”
