简要总结
In recent times, many patients want their treatment duration to be reduced, because lengthy orthodontic treatment duration is associated with negative sequelae such as discomfort, pain, white spot lesions, and decreased patient's compliance. Several techniques have been employed in an attempt to accelerate the tooth movement and shorten the lengthy orthodontic treatment duration. So, this study will investigate the effectiveness of minimal invasive technique like piezocision and microosteoperforation in alleviating mandibular anterior crowding which is one of the common malocclusiom and provide scientific knowledge regarding which minimal invasive tecnique will relieve the crowding faster.
详细描述
Records will be taken from patients who are meeting selection criteria and then analysis of record will be done to attain a proper diagnosis and treatment plan. Afterthat, those patients will be referred to oral surgery department for extraction of first premolar. After healing, orthodontic treatment will be started with bonding of preadjusted MBT 0.022" slot straight wire appliance(Patient will be instructed to report immediately in case of breakage of appliance), after that, randomisation and allocation of two groups will be done and on the day of initial aligning archwire placement i.e., 0.014" NiTi, active interventions(piezocision and micro-osteoperforations) will be done for each group and then levelling and alignment will be continued with the following arch wire sequence 0.016" , 0.016" x 0.022" and 0.017" x 0.025" NiTi. Levelling and alignment will be considered finished when 0.017x0.025" NiTi archwire will be engaged passively in the brackets. Records i.e,. mandibular study models will be taken on the day of surgical procedure before surgery (T0) and then after every 4th week i.e., 4th week(T1), 8th week(T2), 12th week(T3), 16th week(T4). Following this, data collection and interpretation of results will be done. And also, CBCT will be taken at post levelling and alignment with 0.017" x 0.025" arch wire to assess the root resorption and marginal alveolar bone loss.
