Abstract
The purpose of this study was to observe morphologically remodelling and osseointegration of undecalcified bone, and peipheral tissue attached to IMZ implants with 3.3mm in diameter and 6.0 mm in length, being emdedded in rabbit tibia. After 3,
6,
8, 12
weeks, IMZ impants associated with bone tissue were explanted, fixed with 10% neutral formalin, dehydrated, and embeddded with Spurr low viscosity resin, After the specimen was cut by 500§­ with slow diamond wheel saw, these were grinded to 100§­
with
grinder, staine dwith toluidine blue and Villanueva's method, and examined with light microscope.
@ES The results obtained were as follows.
@EN 1. Histopathologic findings of 3 weeks showed IMZ implants mainly surrounded by low density bone, and regular directions of collagen fibers but no inflammatory cell infiltration. Findings of 6 weeks showed new bone well demarcated by compact
bone,
and findings of 8 weeks showed osteocytes with adjacent to implant, and findings of 10 weeks showed high density bone surrounding IMZ implant less well demarcated by compact bone.
2. Toluidine blue of 3 weeks showed strong positivity of low density bone and collagen fibers. Findings of 8 weeks showed high density bone containing increased lamellar and osteocytes with processes. Findings of 10 weeks showed osteocytes among
plasma
parallel to implant.
3. Villanueva of 3 weeks showed IMZ implants partially surrounded by low density bone as light red and brown. Findings 6 weeks showed osteocytes, lacuna, canaliculi, and Harversian canal as red. Findings 8 weeks showed implants mainly surounded
by
high
density bone as brown, and more increased osteocytes. But Findings 10 weeks showed implants surrounded by less denser bone than compact bone.
