[Histopathologic evaluation of the reactivity of soft tissue to dental acrylate implants--in vivo examinations].
Wistar rats were implanted subcutaneously with samples of the home-made metacrylate material Akpol S and, for comparative purposes, with samples of the imported materials Trevalon and Superacryl. Throughout a period of 7 weeks, at 7-day intervals, sections of the tissues surrounding implants were collected from the animals and examined histopathologically. No differences in the character of the inflammatory reaction ensuing around the implants made from the three tested materials were observed. The dynamics of increase in the thickness of a pseudocapsule which developed at the edge of the inflammatory infiltration around the implants made from Akpol S and Trevalon was similar, whereas analogous values for the material Superacryl were higher. The conducted comparative in vivo studies permit us to evaluate positively the home-made metacrylate material Akpol S.
