Dynamics of dental implant stability indicators (ISQ) using low-level laser therapy in treatment and prevention modes

Abstract

The aim of this work was to study the primary and secondary stability of dental implants, installed with the use of pre- and postoperative laser therapy by special device B-CureLaserDentalPro, using the method of frequency-resonance analysis. Photobiostimulation effects of low-level laser therapy device B-CureLaserDentalPro is demonstrated on the example of harmonization of the formation of the bone-implant complex. The blind randomized comparative placebo-controlled prospective study determined that the professional and individual use of a 5th generation diode laser with a wavelength of 808 nm, a power of 250 mW, a pulse frequency of 14 kHz, a defocused beam of 4.5× 1.0 cm, a power flux density of 14.4 J/min at peak (3.2 J/cm2 per min) at the stages of preoperative preparation and postoperative follow-up of dental implantation provides full-fledged osseointegration of implants with secondary stability indicators (ISQ2), determined by the frequency-resonance method (Osstell ISQ), ensuring timely functional loading of the implant with a permanent orthopedic design with a long-term favorable prognosis of treatment. According to the results of the study intra-group, as well as individual indicators of secondary stability of implants when complex of dental implantation included the laser therapy in preventive and therapeutic-rehabilitation regimes met the criterion of excellent and exceeded the indicators of primary stability by 14.6%. In the comparison group, complete osseointegration was observed in 96.5% of patients and with significantly (p < 0.001) smaller (by 5.9%) increase in the ISQ value; treatment failure was recorded in 3.5% of cases (disintegration and implant loss).
