Abstract
The aim of the study was to compare the connective tissue response of Lewis rats to Ti, NiCr and AgPd alloys. It was found that implants were covered by collagen-rich, well vascularized capsules. Titanium was covered by the thinnest capsule (57 Âą 20 Îźm) and AgPd alloy was covered by the thickest capsule (239 Âą 50 Îźm). The PCNA+ cell prevalence in the capsules was lower for titanium than for AgPd and NiCr. Mast cells formed a gradient to a depth of 1200 Îźm only for titanium implants. Cells with brown to black silver granules in the cytoplasm were observed close to AgPd implants. The results suggest that titanium implants induce a weaker connective tissue response than implants made from NiCr and AgPd alloys.
