简要总结
- To compare patients who will undergo orthodontics treatment involving upper premolar extraction for space of time whether with or without corticotomy by Piezotome.
- Assess the safety of both methods of retraction in regard to the quality of the surrounding periodontium and roots of anterior teeth.
- Monitor postoperative pain.

入选标准
- •On the basis of the diagnosis of the malocclusion, individuals who have Class I and Class II malocclusions and requiring extraction of premolars and retraction of anterior teeth will be selected (maxillary/mandibular or both).
- •Good oral hygiene, healthy gingiva and no evidence of bone loss as seen in radiograph.
- •Healthy systemic conditions.
- •No previous orthodontic treatment.
- •Patient needs to be in permanent dentition (hence, we need to define their age range).
排除标准
- •Patient with systemic disease.
- •Patient having any signs of active periodontal disease.
- •Patients on long-term corticosteroid therapy.
- •Persons taking medications that slows down bone metabolism.
- •Craniofacial anomalies.

Quality of orthodontic treatment with straightwire or standard edgewise appliancesMost orthodontic malocclusions can be effectively treated with comprehensive fixed appliance treatment, due to the ability of the latter to perform controlled tooth movements in all three planes of space. Often, severe arch length discrepancies or several dental/skeletal malocclusions necessitate the incorporation of dental extractions in the orthodontic treatment plan.Oral HealthISRCTN13048456niversity of Zurich50
