The aim of the present study was to evaluate bone loss at implants connected to abutments coated with a soda-lime glass Toddler Sunglasses containing silver nanoparticles, subjected to experimental peri-implantitis.Also the aging and erosion of the coating in mouth was studied.Five beagle dogs were used in the experiments.

Three implants were placed in each mandible quadrant: in 2 of them, Glass/n-Ag coated abutments were connected to implant platform, 1 was covered with a Ti-mechanized abutment.Experimental peri-implantitis was induced in all implants after the submarginal placement of cotton ligatures, and three months after animals were euthanatized.Thickness and morphology of coating was studied in abutment cross-sections by SEM.

Histology and histo-morphometric studies were carried on in undecalfied ground FERMENTED PROTEINS slides.After the induced peri-implantitis: 1.The abutment coating shown losing of thickness and cracking.

2.The histometry showed a significant less bone loss in the implants with glass/n-Ag coated abutments.A more symmetric cone of bone resorption was observed in the coated group.

There were no significant differences in the peri-implantitis histological characteristics between both groups of implants.Within the limits of this in-vivo study, it could be affirmed that abutments coated with biocide soda-lime-glass-silver nanoparticles can reduce bone loss in experimental peri-implantitis.This achievement makes this coating a suggestive material to control peri-implantitis development and progression.
