[Animal model for the study of the biocompatibility of root filling materials].
The aim of this study was to investigate the influence of different pins usually used for intraoperative root filling on periapical bone healing. In a specially designed animal experiment it was possible to evaluate biocompatibility simultaneously with the influence of varying materials on bone regeneration in standardized defects. Bioincompatible silver, acrylate and gutta percha root filling delay and impede bone regeneration. Biocompatible aluminium oxide ceramic and titanium pins do not have any influences on spontaneous bone regeneration. Reducing the defect, however, they do improve the conditions for complete bony regeneration.
