Abstract
The purpose of this study was to observe the change of bone and peripheral tissue around IMZ implants on 3, 6, 8, 10, and 12 weeks in rabbit tibia morphologically.
TPS-IMZ extraoral implants with 3.3mm in diameter and 6mm in length were implanted in rabbit tibia. For reflection electronmicroscopic study, IMZ implants were explants were explanted, fixed with 10% neutral formalin, coated with Au-Pd, and
examined
with reflection electronmicroscopy.
@ES The obtained results were as follows.
@EN 1. Irregular osteoid like tissue in the upper portion of IMZ implant and less mineralized bone tissue surrounding implant, which was well demarcated from old bone tissue after 3 week implantation.
2. There were irregular trabecular pattern of less mineralized bone containing numerous osteocytes in the upper portion of IMZ implant, showing well demarcated line from old bone tissue and Haversian canals attached to implant after 6 week
implantation.
3. There was increased mineralized in the upper portio of IMZ implant after 8, 10 week implantation. Various density of mineralization between adjacent bone tissue around implant and old bone was decreased but osteocytes in newly formed bone
tissue
were more increased than those of old tissue.
4. There was poorly demarcated line between newly formed bone tissue and old bone and newly formed bone was intermingled with old one and less mineralized bone tissue around Haversian canals after 12 week implantation.
