NCT04170127

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • stability of orthodontic mini-implants

    The mini-implants stability was estimated employing a Periotest device (Medzintechnik Gulden e K, Modautal, Germany). The Periotest measurement system includes the sound formed from contact between an object and a metallic tapping bar in a handpiece, which is electromagnetically driven and electronically verified. The Periotest response detection is analyzed through a fast Fourier transform (FFT) algorithm. Simply put, the Periotest answer to tapping is estimated by an accelerometer and then analyzed. The signal generated by tapping is then transformed to a value called the Periotest value (PTV), which depends on the damping characteristics of the peri-implant tissue. \[27\] The Periotest Test values (PTVs) are based on a numerical scale ranging from -8 to +50, defined by mathematical computation. The lower Periotest values indicate higher implant stability and thereupon the higher absorption effect of the target objects.
