Study Overview
Brief Summary
The long time needed for orthodontic treatment is considered one of the biggest obstacles that make patients refuse to undergo orthodontic treatment. It also has many disadvantages including higher caries rates, gingivitis, and root resorption. Therefore, the purpose of this study is to evaluate the efficiency of two new noninvasive methods (Low-Level Laser Therapy and Corticopuncture) in accelerating orthodontic tooth movement for the implant supported En-Masse retraction of the six maxillary anterior teeth.
Detailed Description
This study will be a randomized controlled trial with a 1:1:1 allocation ratio. Sample size was calculated using Minitab version 15. 36 Participants recruited from patients attending the Department of Orthodontics and Dentofacial Orthopedics at Damascus University with class II division 1 malocclusion that indicates the extraction of first maxillary premolars will be randomly assigned into one of three groups: Low-Level Laser Therapy (LLLT) group, flapless corticopuncture group, or control group. Titanium mini-implants (1.6 mm diameter and 7 mm length) will be inserted between the maxillary second premolar and first molar at approximately 8-10 mm height above the archwires below the mucogingival junction. After complete leveling and alignment of the maxillary dental arch, which will be defined by passive insertion of 19*25 inch S.S. archwire, the retraction stage of the six maxillary anterior teeth will begin.

Outcomes
Primary Outcomes
Duration of en-masse retraction of the six maxillary anterior teeth
Time Frame: The months required to complete the retraction procedure will be recorded, which is expected to be occur within four months
Assessment will be performed by calculating the time required from the beginning of the six maxillary anterior teeth retraction till the completion of this procedure
Rate of en-masse retraction of the six maxillary anterior teeth
Time Frame: The calculation of the rate of retraction will be done once the retraction procedure has finished which is expected to occur within four months
Assessment will be performed on study models by dividing the distance that the six maxillary anterior teeth moved during retraction to the time required to retract them to their ideal positions.
Secondary Outcomes
- Maxillary first molar anchorage loss(This outcome will be measured one day before upper incisors' retraction initiation (T0) and immediately after the completion of retraction (T1) which is expected to occur in 4 months)
- Root resorption(A CBCT image will be taken one day before the six maxillary incisors retraction initiation (T0) and immediately after the completion of retraction (T1) which is expected to occur in 4 months)
- Changes in the gingival indices(This outcome will be measured one day before the six maxillary incisors retraction initiation (T0) and immediately after the completion of retraction (T1) which is expected to occur in 4 months)
- Change in tooth vitality (the response of the pulp tissue toward external stimuli)(This outcome will be measured one day before the six maxillary anterior teeth retraction initiation (T0) and immediately after the completion of retraction (T1) which is expected to occur in 4 months)
- Changes in the levels of pain and discomfort(These levels will be assessed at: one day, one week, two weeks, and four weeks following the intervention)
- Change in the Oral Health Related Quality of Life associated with anterior teeth retraction.(The OHIP-14 will be assessed immediately after application, after 1, 7, 14, and 28 days of the six maxillary anterior teeth retraction initiation)
