Effect of diode laser biostimulation on implant stability, post-surgical inflammation, and bone healing in immediate implant in the maxillary premolars. A randomized double-blind trial

Abstract

The stimulatory effects of laser Biostimulation on immediate implant clinical wound healing and radiographic bone quality analysis is with insufficient evidence. To evaluate the effect of low-level diode laser as a biostimulatory bolster for immediate implants in maxillary premolars. The study was conducted as a double-blinded randomized clinical trial on 20 patients with unrestorable maxillary premolars with a Type I socket. Patients were divided into two groups, where those who received immediate implant with laser biostimulation were assigned to the study group, while a sham laser application was used in the control group. Implant stability was appraised using radiofrequency analysis. Radiographic evaluation was conducted using an immediate post-operative and after 4-months tomographic scans. Implant stability analysis showed a significant difference in the reported secondary stability values in the irradiated group. The healing index quantitative assessment of wound healing, reported significantly higher scores compared to the control group at all follow-up points. Radiographic bone density and labial plate thickness showed statistically insignificant differences. The overall success rate, secondary implant stability, and radiographic performance were comparable to those of the control group. These findings suggest that the biostimulatory effects of the laser are limited in the long term, offering no significant additional benefits over conventional methods.
