The Effect of Corticotomy in En-mass Retraction

NCT ID: NCT03180151

Last Updated: 2023-10-03

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 26 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2016-09-30
• Study Completion Date: 2018-01-31

Brief 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.

Conditions

Accelerate Tooth Movement

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Orthodontic tooth movement group

This is the control group in which pateints will be treated by conventional orthodontic treatment and extraction of premolars without piezotome

Group Type: NO_INTERVENTION

No interventions assigned to this group

Corticotomy assisted orthodontic group

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)

Group Type: EXPERIMENTAL

piezotome assisted orthodontic tooth movement

Intervention Type: PROCEDURE

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.

Eligibility Criteria

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.

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 26 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: Yes
