5. Conclusions
- Patients treated with MARPE show torque increases in the teeth selected to support the expansion appliance compared to cases treated with BAME.
- In cases where the upper molar torque was correct at the beginning of the treatment, a slight bone insertion gain was observed.
- In cases where the upper molar torque was negative or positive, a slight bone insertion loss was observed.
- Regarding the labial cortical bone loss, a slight gain of CBW was observed in all cases. This increase in labial cortical is higher in cases where posterior molar torque was negative before treatment.
