抄録

Currently, osteointegrated implants are commonly used. In this study, the effects of osteoporosis on the bone around the implant was observed. Hydroxyapatite implants were inserted in the tibiae of female adult rats and then ovariectomized. One, 2 and 4 months after ovariectomy, the bone around the implants were observed histologically. In the experimental group, the bone to implant contact ratio was lower than that in the control group. At the substansia compacta, the implants were connected to the bone but at the substansia spongiosa, they were almost covered by connective tissues, and the surface of the implants were irregular in places. These findings suggested that the convalescence of the implants should be observed carefully during osteoporosis.
