About

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.

Full 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.

36 participants in 3 patient groups

Low-Level Laser Therapy (LLLT)

Experimental group

Description:

In the LLLT group, a low-level laser with wavelength of 808 nm, output of 250 mW, energy of 4 Joules per point and application time of 16 seconds per point will be applied on each tooth of the six maxillary anterior teeth according to this protocol: the root will be divided theoretically into 2 halves; gingival and cervical, and laser will be applied in the center of each half from both buccal and palatal sides which means 4 application points and a total energy of 16 Joules per tooth.

Treatment:

Radiation: Low-Level Laser Therapy (LLLT)

Flapless Corticopuncture

Experimental group

Description:

In the flapless corticopuncture group, 3 interdental punctures located between the roots of the six maxillary anterior teeth from both the buccal and palatal sides, will be done using a 1-mm diameter round surgical Tungsten bur with 1 mm depth and 1.5 mm space between each puncture. These punctures start 2 mm from the free gingiva. Besides, an additional 2 parallel set of punctures with the same dimensions of the interdental ones will be done in the extraction sockets from both the buccal and palatal sides.

Treatment:

Procedure: Flapless Corticopunture

Control

Experimental group

Description:

Patients in control group will undergo typical orthodontic treatment only with no LLLT or flapless corticopuncture application.

Treatment:

Other: Control
