Abstract
The dental implant surface type is one of many factors that determine the long-term clinical
success of implant restoration. The implant surface consists of bioinert titanium oxide, but recently
coatings with bioactive calcium phosphate ceramics have often been used on Ti implant surfaces.
Bio-active surfaces are known to significantly improve the healing time of the human bone around
the inserted dental implant. In this study, we characterized two types of coated implant surfaces by
scanning electron microscopy, energy dispersive spectrometry, and surface roughness testing. The
effect of surface modification on early bone healing was then tested by using the rabbit tibia model
to measure bone-to-implant contact ratios and removal torque values. These modified surfaces
showed different characteristics in terms of surface topography, chemical composition, and surface
roughness. However, no significant differences were found in the bone-to-implant contact and the
resistance to removal torque between these surfaces. Both the coated implants may induce similar
favorable early bone responses in terms of the early functioning and healing of dental implants even
though they differed in their surface characteristics.
