Description détaillée
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.

Armes et Interventions
Groupe de participants / Bras |
Intervention / Traitement |
|---|---|
|
Expérimental: Corticotomy-assisted Retraction
Corticotomy-assisted retraction will be performed in order to help in accelerating upper incisors' retraction
|
Using a tunneling technique, the researcher will perform the intervention in the alveolar bone surrounding the upper incisors before retraction.
|
|
Aucune intervention: Conventional Retraction
Conventional retraction will be used in this group of patients by sliding mechanisms
|
Que mesure l'étude ?
Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Rate of retraction
Délai: This will be measured at the completion of the retraction procedure, and is expected to take 2 months in the experimental group and four months in the control group.
|
The distance that the incisors moved during retraction divided by the time required to retract the four upper incisors to their ideal positions.
|
This will be measured at the completion of the retraction procedure, and is expected to take 2 months in the experimental group and four months in the control group.
|
|
Time required for retraction
Délai: This will be measured at the completion of the retraction procedure, and is expected to be within 2 months in the accelerated group and 4 months in the control group.
|
The time required from the beginning of incisors' retraction till the the completion of this procedure.
|
This will be measured at the completion of the retraction procedure, and is expected to be within 2 months in the accelerated group and 4 months in the control group.

Description de la mesure |
Délai |
|---|---|---|
|
Change in the axial inclination of upper incisors
Délai: A radiograph will be taken at T1: one day before upper incisors' retraction and T2: one day after the completion of upper incisors' retraction. Completion of upper incisors' retraction is expected to be within 2 months in the accelerated group and 4 mo
|
the angle between the long axis of the upper incisor and a reference plane drawn on a later cephalometric radiograph teken at two assessment times.
|
A radiograph will be taken at T1: one day before upper incisors' retraction and T2: one day after the completion of upper incisors' retraction. Completion of upper incisors' retraction is expected to be within 2 months in the accelerated group and 4 mo
|
|
Anchorage loss
Délai: This will be measured one day following the completion of retraction of the upper four incisors using plaster study models and is expected to be within 2 months in the accelerated group and 4 months in the control group
|
the amount of anchorage loss (in mm), which is the distance from a perpendicular line to the midpalatal suture and extends between central fossa of both upper first molars to the third palatal rugae .
These measurements are made on plaster study models.
|
This will be measured one day following the completion of retraction of the upper four incisors using plaster study models and is expected to be within 2 months in the accelerated group and 4 months in the control group
|
|
Root resorption
Délai: An panoramic image will be taken at T1: one day before the commencement of incisor retraction and T2: one day following the completion of retraction and is expected to be within 2 months in the accelerated group and 4 months in the control group
|
This variable is related to the amount of incisor root resorption after treatment in both groups.
This is measured on a panoramic image.
The amount of root resorption = the length of an incisor after retraction subtracted from the length of an incisor before retraction.
Two radiogrpahs are needed.
|
An panoramic image will be taken at T1: one day before the commencement of incisor retraction and T2: one day following the completion of retraction and is expected to be within 2 months in the accelerated group and 4 months in the control group
