Photobiomodulation Therapy to Stimulate Autonomous Eruption of Palatally Impacted Canines After Conventional Surgery: A Split-Mouth Case Report

Year: 2025

Type: article

Abstract: Background: The aim of this study was to evaluate the effect of Photobiomodulation Therapy (PBMT) on the eruption rate of impacted maxillary canines after surgery, using a split-mouth design. Methods: A 16-year-old patient was referred to the Department of Oral and Maxillo-Facial Sciences of “Sapienza” University of Rome. Clinical examination revealed the persistence of maxillary primary canines and the absence of a palpable canine bump. CBCT scans confirmed that both upper permanent canines were impacted in the palatal osteomucosal region and showed a mesial inclination. Conventional surgery with cold blade was performed for both impacted canines, and PBMT was applied on element 2.3 for three sessions after surgery. Since this is a case report, no statistical analysis was performed. Results: The eruption movement of the two impacted canines was evaluated 16 weeks after surgery. The extent of the spontaneous eruption movement of element 1.3 was 0.21 mm, while element 2.3, which underwent three sessions of PBMT following surgery, moved 3.16 mm. Conclusions: The element that underwent PBMT appears to respond positively in terms of spontaneous eruption following disinclusion surgery compared to the contralateral element that was not stimulated with the laser. These findings suggest that photobiomodulation therapy could be effective in accelerating the eruption of palatally impacted canines following surgery, avoiding the need to use orthodontic traction. Future randomized controlled clinical trials are needed to demonstrate these preliminary results.
