Details and patient eligibility

About

The study aimed to clinically estimate an influence of a 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 20 patients (13 women and 7 men; age: 32.5 ± 6.1 years).

Enrollment: 20 patients

Sex: All

Volunteers: Accepts Healthy Volunteers
