Abstract

Medpor(R) (porous polyethylene) Surgical Implants are used for the augmentation of restoration of bony contour in craniofacial defects. The purpose of this study is to evaluate the ingrowth of soft tissue and bone after application in calvaria of rats. The experiment was carried out in 60 rats. The reflected periosteum was resutrured after implantation of Medpor(R) as a experimental site, while in the calvarial bone the reflected periosteum resutured without implantation as a control site. While in the calvarial bone the reflexted periosteum resutured without implantation al a control site. The histologic examination was performed after 1,-,2-,4-,8-,12-,24-, weeks implantation in calvaria of rats. I concluded that there was avundant ingrowth of soft tissue and bone without any adverse tissue fespones and that it shows good stability.
