研究概览
简要总结
The goal of this clinical trial is to compare rate and amount of space closure among fresh vs healed extraction sites during fixed orthodontic treatment in patients with all first premolar's extraction Primary outcome measure is to calculate rate and amount of space closure between fresh vs healed as well as maxilla and mandible.
详细描述
The mandibular and maxillary arches of 34 patients will be included whose treatment plan decision was the extraction of all first premolars. Due to the split mouth approach, patients' maxillary and mandibular arches are randomly subdivided into two groups (right and left sides). First premolar extraction spaces in Group 1 will be closed once they have healed (6 week), while first premolar extraction spaces in Group 2 will be closed immediately after extraction. Both the upper and lower extraction spaces will be closed using coil springs (magnitude of force 30g per side). We'll specify the following time intervals: T1: Immediately prior to space closure; T2: 1 month after initial space closure; T3: 2 months after initial space closure T3: 3 months after initial space closure. Records will include measuring the rate and amount of space closure through Vernier calipers on dental cast as well as intraorally and will be evaluated at each time point.

结局指标
主要结局
To compare rate of space closure among fresh vs healed extraction sites during fixed orthodontic treatment in patients with all first premolar's extraction.
时间窗: four time points are taken. T0: Baseline, T1: One month, T2: Two months, T3: Three months
This study will be useful in making the timely decision for extraction of premolars and estimation of orthodontic treatment duration as well.
次要结局
- To compare amount of space closure among fresh vs healed extraction sites during fixed orthodontic treatment in patients with all first premolar's extraction.(Space closure at T3 is subtracted from T0)
