Photobiomodulation of Orthodontic Mini-implants by a 635nm Diode Laser

Photobiomodulation of Orthodontic Mini-implants by a 635nm Diode Laser: Primary and Secondary Stability. A Randomized Clinical Split-Mouth Trial.

The study aimed to estimate clinically an influence of 635nm diode laser on the primary and secondary stability of orthodontic mini-implants placed in a maxilla, to assess mini-implants failure rate (mini-implant loss) and to evaluate a pain level after the treatment. The randomized clinical split-mouth trial included 15 subjects, 30 implants (Dual Top Anchor System, Seoul, Korea) with a diameter 1.4mm and length of 10mm. Mini-implants were placed in the area of the attached gingiva between the second premolar and first molar teeth 2 mm below the mucogingival junction of both sides of the maxilla in 15 patients.

Inclusion Criteria:

• patients with class II malocclusion defect requiring lateral maxillary teeth distillation based on the use of orthodontic mini-implant;
• the patients were treated first time using fixed orthodontic appliance;
• no systemic diseases;
• were not using anti-inflammatory drugs;

Exclusion Criteria:

• had used antibiotics in the previous 24 months;
• smokers;
• had history of radiotherapy,
• taking bisphosphonate medication
