| ABSTRACTBackground: The new trend of coating implants with biological molecules has result in improvement inosseointegration. Natural plants can provide biological molecules which are biocompatible, abundant in source, haslow cost and can be modified to host properties. The aim of this study is to evaluate the influence of coating implantwith black seed oil extract on the strength of bone implant interface mechanically and histologicaly.Material & methods: Forty eight CpTi screw shaped implants (3.75mm in diameter, 8 mm in length) were placed in thetibiae bone of twelve New Zealand rabbits. Each animal received 4 implant (2 uncoated and 2 coated with blackseed oil extract by dip coating technique). Twelve implants removed after each healing period of 2, 6 and 12 weeksusing digital torque meter device constructed for the purpose of this study and four implants removed with boneblock for histological study at each healing period.Results: The mean removal torque values for coated implants were higher significantly than the uncoated implantsover different time periods. In addition the histological picture show improved quality of bone response among thecoated screws.Conclusions: The coated implants seemed to be well tolerated by the bone since no adverse tissue reaction wasevident and they have better torque resistance and appear to produce osteophilic surface favoring earlyosseointegration.Key words: nigella sativa, dip coating, dental implant, biochemical modification.
