-Summary

* 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.

+Arms and interventions

Arm	Type	Interventions	Description
Orthodontic tooth movement group	No intervention		This is the control group in which pateints will be treated by conventional orthodontic treatment and extraction of premolars without piezotome
Corticotomy assisted orthodontic group	Experimental	Procedure: piezotome assisted orthodontic tooth movement	This is the study group in which patients will be treated by conventional orthodontic treatment aided by corticotomy procedure perfumed by using a piezotome.(piezotome assisted orthodontic tooth movement)

piezotome assisted orthodontic tooth movement (Procedure), also known as corticotomy assisted tooth movement: Surgical procedure 1. After local anesthesia, vertical interproximal incisions will be done under the interdental papilla, on the labial aspect of upper arch using a blade No. 15. 2. The incisions will be kept minimal. 3. The incisions go though the periosteum, which permit the blade to reach to the alveolar bone. 4. A Piezo surgical knife will be used to make the cortical alveolar incision through the gingival incisions to a depth of approximately 3mm. 5. As we will not use bone graft so we don't need use suturing after cortication. 6. We give patient antibiotic and analgesic cover.

rate of tooth movement per time [4 months]

+Eligibility

Sex: All, ages: 18 Years to 26 Years, accepts healthy volunteers

Inclusion Criteria:

* 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).

Exclusion Criteria:

* 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.
