Influência da terapia com laser de baixa potência em implantes unitários imediatos: ensaio clínico randomizado

Abstract

Immediate implants are an important treatment option, which reduces the cost and time of treatment, as well as the surgical and psychological factors of the patient, and it also allow the maintenance of the pre-existing periodontal architecture. The low-level laser therapy is used for photobiological, photophysical, and photochemical actions on irradiated tissues. The objective of this study was to evaluate the influence of low-level laser therapy after tooth extraction and the placement of single implants in patients during the years of 2017-2018 at the School of Dentistry of the Federal University of Pelotas. Fortyfour immediate implants were performed in two randomized groups: control and laser group. Implant survival, marginal bone loss, were assessed in a period of 180 postoperative days. T-test and Chi-square were used to characterize the surgical and post-surgical outcomes (p=0.848 and p=0.662, respectively). After the period of osseointegration, we observed the formation of a peri-implant bone panel in the main cases evaluated. Lower levels of post-operative pain and the number of medications used for pain relief were observed for laser group patients; however, no statistical difference was found. Of the 27 implements it is evaluated, 100% is success in survival, ISQ greater than 60, both at the beginning (T0) and at the end (T180). It concludes that the use of the low-level laser did not significantly affect the survival rate, marginal bone loss and post-operative pain.
