What this Trial Is About
The main goal is to test the differences between the retentive capacity of fixed retainer, vacuum-formed retainer \& combination of both; and recommend the most effective protocol for retention of lower incisors crowding treated by non-extraction treatment plan The main question is: In patients with lower incisors crowding treated by non-extraction treatment plans, what is the difference in retentive capacity between fixed retainer, vacuum formed retainer and combined bonded and vacuum retainers in maintaining corrected lower anterior segment crowding? After enrolment, each participant will have the orthodontic appliance debonded, the adhesive remnant removed and the enamel surface polished. An alginate impression will be taken to be poured into a study model which will be scanned to obtain STL files for digital models. All patients will have periodontal charting and probing depths recorded for the lower anterior segment. According to the randomization, each patient will be assigned to a group to receive the retainer. All patients will be called for follow-up after 1 week, 1 and 3 months.
