چکیده
|
The aim of this study was to investigate bone response to bioactive fiber-reinforced composite (frc) implants under two polymerization conditions. glass-fiber-dimethacrylate composite was tested as prepolymerized cylinder-shaped frc implants and as cylindrical frc implants polymerized in situ with blue light transmitted and scattered by the glass fibers. ten frc implants (6 prepolymerized and 4 in situ -polymerized implants) were placed in the right tibias of 3 pigs by means of a press-fit technique. after 12 weeks,light microscopy revealed only mild foreign-body reaction,with no accumulation of inflammatory cells on both the prepolymerized and the in situ-polymerized implants. the prepolymerized implants appeared to be fully integrated,whereas the in situ-polymerized implants were almost completely surrounded by a fibrous capsule. the present study suggests that in situ polymerization of frc implants results in fibrous capsule formation and prevents integration with bone. © international & american associations for dental research.
