Abstract
Five cases, to which screw-type Bioceram Implants were applied, were observed to evaluate biophysical behavior of implant-supporting tissues to horizontal stress for six months after implantation. Ten natural teeth were also tested as control.
Results obtained were as follows:
Following the increasing stress, displacement rate in natural teeth declined exponentially, while linear increases were seen in implants. Maximal increase in mobility was seen in the 2nd month after implantation, thenceforth gradually decreased, and the least displacement was indicated in the 6 th month.
Two phasic curves seen in the recovery course after releaseing stress have significantly increased in size in 2nd month.
Mean speed in the 2nd phase of recovery curve (D3/T3) was about twice as rapid as natural teeth were, except in the 2nd month. From above mentioned facts, it might be assumed that supporting mechanism of implants would differ from ones of natural teeth, showing rather elastic response.
