Background: The invention of the preadjusted appliance allowed for simpler mechanics and less wire bending. The expression of the inbuilt tip and torque incorporated into its slot or base is possible after full engagement of rectangular wire. This have its implication on inclination and angulation of the teeth

Aim and objectives: The study aimed to assess the inclination and angulation of maxillary anterior teeth using different commercially available MBT bracketsystem using CBCT scans.

Materials and Methods: Thirty-three subjects were divided into two groups. Group 1 bonded with GeminiTM (3M Unitek) MBT Bracket System and Group 2 bonded with Mini DiamondTM (Ormco) MBT Bracket System. Two CBCT scan was taken after 6-8 weeks of placement of 0.019"x0.025" SS archwire (T0) and 0.021" x 0.025" SS archwire (T1) of same patient. Each evaluated data was entered into excel sheet and analysed using Shapiro Wilk test.

Result: The mean change in inclination and angulation in either group was found to be statistically insignificant at T0 and T1 whereas the mean change from T0 to T1between the 2 groups were found to be statistically significant in all six maxillaryanterior teeth.

Conclusion: The result showed no significant difference observed in inclination & angulation of maxillary anterior teeth in both groups at T0 and T1. Whereas the mean change from T0 to T1 was maximum and statistically significant in Group I compared to Group II.
