Introduction

Maxillary canine is the most frequent dental element that could likely remain impacted in the bone structure, with a
percentage between 1 and 5%. This study presents a case report using a diode laser for surgical-orthodontics disinclusion of a
palatal mucosal impacted permanent left upper canine (2.3) and the simultaneous application of an orthodontic bracket.

Materials and methods

After cementation of the trans-palatal bar to the upper first molars with a hook for orthodontic traction, local
anaesthesia with articaine was performed, followed by surgical operculectomy using a diode laser (810 nm wavelength,
continuous wave mode with a power output of 3 W, and a 0.4 mm diameter optical fiber), and the orthodontic bracket with a
passive metal looped ligature was applied. Subsequently, active elastic traction was applied on 2.3 and the upper arch was
bonded for the application of a series of orthodontic wires, lace-back, and metal ligatures. A progressive reactivation of the
elastic traction and extraction of 6.3 was necessary to translate the canine into the correct arch position.

Results

Diode laser
surgical-orthodontic disinclusion of impacted upper canine was performed successively, resulting in a dry surgical field ideal
for orthodontic bracket adhesion. No pain and no swelling have been reported from the patient. The orthodontic treatment
allowed the canine to be moved to the correct position in the arch.

Conclusions

This case showed that the diode laser is a valid
alternative for the surgical-orthodontic disinclusion of an included tooth element.
