About this study
Official title: 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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. 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.
Measured: 60 days
Secondary outcomes (2)
Pain level (NRS scale)
Each patient received a questionnaire for individual pain assessment (the numeric rating scale, NRS-11, grade level 0-10) immediately following placement of mini-implants. The maximum pain level was measured at both sides of the maxilla during the first day after the treatment. The NRS-11 scale consists of a conscious, subjective assessment of the pain experienced; therefore, it is used in the case of patients over ten years old.
0 = no pain, 1-3 = mild pain, 4-6 = moderate pain, 7-10 = severe pain.
Measured: 24 hours
mini-implants loss
Mini-implants survival rate was assessed during 60 days observation period.
Measured: 60 days
