case_images: Panoramic and lateral cephalometric radiographs were taken (Figures 1(d) and 1(e); Cranex  D, Soredex , Tuusula, Finland): the panoramic radiograph showed the presence of third molars' germs, lower deciduous canines' persistence, and upper left canine's impaction without apparent left maxillary incisors' radicular resorption. Intraoral pictures (Figures 1(a)-1(c); taken with Nikon Digital Camera D3500, Nikon Corporation, Tokyo, Japan) showed coincident dental midlines, deep bite, conservative treatments on upper central incisors, and upper lateral incisors' malposition.

case_images: After local anaesthesia (Septanest, articaine hydrochloride 4% with adrenaline 1/100,000), a diode laser (Fotona XD-2, Fotona d.o.o., Ljubljana, Slovenia) was used to perform surgical operculectomy, being an element in superficial palatal impaction, with the following parameters: 810 nm wavelength, continuous wave mode with a power output of 3 W and a 0.4 mm diameter optical fiber (Figures 3(a) and 3(b)).  Figure 4 shows how the surgical incision did not cause intra-operative bleeding, thus creating an ideal condition for the adhesion of the orthodontic bracket.
