The goal of this split-mouth randomized controlled trial is to assess whether the timing of extraction space closure-early vs. delayed initiation-affects the incidence of gingival cleft development in orthodontic patients. The main question it aims to answer is: Does the incidence of gingival cleft development get influenced by the specific time point at which orthodontic space closure is initiated following extraction? Quadrants will be assigned to the early movement group and the other to the delayed movement group and extractions will be performed accordingly. These will be assessed for the effect on development of gingival cleft development.

presence of gingival clefts after space closure initiation
The primary outcome will be the presence of gingival clefts, which will be measured at 3 months and 6 months after space closure initiation
