Abstract: After high success rate of using dental implants in restoration of missing teeth, attention now shifted toward immediate loading of dental implant through improving the osseointegration, this can achieved by coating the dental implants by biocompatible materials. The aim of this study was evaluation the osseointegration of dental implants histologically. Dip coating technique was used to obtain thin homogenous coating on commercially pure titanium screws. Tibia of 6 white New Zeeland rabbits was chosen as implantation site, screws divided into 2groups, first group coated with nano hydroxyapatite, chitosan and collagen composite coating, second group coated with nano hydroxyapatite for 2 and 6 weeks of healing periods. Histological analysis showed increasing new bone formation for the nano hydroxyapatite, chitosan and collagen composite coated implants than nano hydroxyapatite coated implants and over the two periods of time. As conclusion screws coated with nano hydroxyapatite, chitosan and collagen composite was more efficient than nano hydroxyapatite coating.
