<br/><br/> Objective : To measure the bond strength of different types of lingual retainers in combination with different types of composite materials . Results : Upon loading at 45 degrees angle the MS was the weakest wire related to its inherent strength, while no statistically significant difference between DS , RM and biosplint retainers was found all showed the highest mean maximum load required to cut the retainers
