Sixty stainless steel brackets were divided into two groups, group I used coarse
mesh base type (Dentaurum); group II used casted mesh base type (Orthoorganizer).
Each group was subdivided into three sub groups (Ten brackets for each), all the
brackets were bonded to sixty sound freshly extracted human upper first premolars
teeth using Microfilled composite material cured with light emitted diode (LED) light
cure unit. The first sub group was bonded with 5th generation bonding system; the
second group was bonded with 6th generation bonding system, while the third sub
group bonded with 7th generation bonding system.
The results of this study revealed that the 7th generation shows higher shear bond
strength than other two groups. The brackets with casted mesh type base demonstrate
higher shear bond strength than brackets with coarse mesh type base.
