Abstract

STATEMENT of PROBLEM: There were several studies on the effects of irradiation to periimplant bone tissue. However, no clear biological effect of irradiation on peri-implant bone tissue was reported yet. PURPOSE: This study compared the effect of irradiation on the surrounding tissue of a HA-coated implant fixture with controls. MATERIAL AND METHODS: 6 Steri-Oss implants were implanted into the femur of 6 mongrels. The implanted dogs were divided into three groups and received irradiation. After 1 month, 2months and 4 months healing period, the histologic examination and mobility test and digital radiographic imaging analyses were performed to compare the control and experimental group respectively.
RESULTS
The irradiated group showed slower healing than control group in light microscopic observations. The mobility test demonstrated significant less number (Periotest) in control group than that of irradiated groups. The digital radiographic imaging analysis showed that the bone density of irradiated group was higher than control group.
CONCLUSION
Generally, control group showed favorable bilogical response and less mobility than irradiated group. The conflict result of bone density value were measured by the dig-.
