title: [A biomechanical investigation of Ha-coated ceramic implant]
abstract: Two samples of Ha-coated ceramic implants of which sintering temperatures were 850 degrees centigrade,1050 degrees centigrade respectively,were prepared.Pure titanium implant of the same size was accomplished using a transcortical implant model in adult Mongrel dogs.Follow-up periods were 1,3 and 6 months.The results in vivo were evaluated using push-out tests and scanning electron microscope.There were significant differences in push-coated ceramic implants and pure titanium implants,especially for the 1 and 3 months follow-up period.SEM investigation of the interface after push-out test showed for the HA-coated ceramic implants to be fractured in the coating layer and for the Ti-implant to be fractured at the implant-bone interface.
