Brief Summary

We aim to assess the treatment outcomes following upper incisors retraction accelerated by corticotomy procedure. So, we intend to randomize orthodontic patients with class II division I malocclusion into two groups: experimental group and control group. Both groups will start orthodontic treatment. Once a 0.019*0.025-inch stainless steel wire is fully engaged to the brackets, 1st premolars will be extracted. Canines will be retracted in the conventional manner. Then, the actual evaluation period starts when the upper incisors are retracted using two different methods.

Detailed Description

In the last three decades, the number of adult patients seeking short orthodontic treatment time has apparently increased as the conventional orthodontic treatment usually lasts for 20-24 months. Furthermore, orthodontic treatment is often associated with root resorption, bone degradation and caries development. Patients nowadays desire to end the orthodontic treatment as soon as possible due to phsycosocial reasons and to get the goals of the treatment without affecting their social life .

So many tooth movement accelerating methods have been proposed. However, the surgical approached are considered the most effective and promising methods in accelerating tooth movement. The current research aims to evaluate the efficacy of the a new proposed surgical method compared to the conventional method in upper incisors' retraction.

Conditions

Class II Division 1 Malocclusion

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

Corticotomy-assisted Retraction

Corticotomy-assisted retraction will be performed in order to help in accelerating upper incisors' retraction

Group Type: EXPERIMENTAL

Corticotomy-assisted Retraction

Intervention Type: PROCEDURE

Using a tunneling technique, the researcher will perform the intervention in the alveolar bone surrounding the upper incisors before retraction.

Conventional Retraction

Conventional retraction will be used in this group of patients by sliding mechanisms

Group Type: NO_INTERVENTION

No interventions assigned to this group

Interventions

Corticotomy-assisted Retraction

Using a tunneling technique, the researcher will perform the intervention in the alveolar bone surrounding the upper incisors before retraction.

Intervention Type: PROCEDURE
