Effect of Photobiomodulation by 808nm Diode Laser on the Stability of Orthodontic Mini-implants.

Effect of Photobiomodulation by 808nm Diode Laser on the Stability of Orthodontic Mini-implants: A Randomized Clinical Split-Mouth Trial.

The study aimed to evaluate the influence of a 635nm diode laser on the stability of orthodontic mini-implants in vitro, as well as mini-implants failure rate (mini-implant loss) and patients pain level after the treatment. A randomized clinical split-mouth trial was concluded with 22 subjects (14 women, 8 men), 44 orthodontic mini-implants with a diameter 1.4mm and length of 10mm. Mini-implants were placed between teeth 3 and 4; and 13 and 14 (Universal Numbering System), in the area of the attached gingiva, 2 mm below mucogingival junction.

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
