This case report describes a new orthodontic-surgical approach through the use of CO2 laser, for the exposure of the palatally impacted canines. A 13-year-old female referred to our observation to make an orthodontic examination because of the maxillary primary canines\u2019 persistence in upper arch. Orthopanoramic X-ray showed impaction of both permanent maxillary canines. The family history revealed that the patient\u2019s mother had the same orthodontic problem. Cone Beam Computer Tomography (CBCT) was requested to plan the surgical-orthodontic treatment. Surgical exposure of the impacted canines was performed using a CO2 laser and subsequent periodontal pack application. No orthodontic devices were applied for impacted teeth traction on dental arch. Canines\u2019 movement was monitored at 1, 8 and 16 weeks post-surgery with photo and intraoral scanner CS3500 (CS3500\u00ae, Carestream Health, Atlanta, GA, USA). When canine crowns were completely erupted on palatal side, the alignment in the arch with indirect bonding technique was performed. Complete disimpaction of canine crowns was obtained in only four months. As reported in the literature, this case confirms that impacted canines\u2019 exposure to CO2 laser has advantages if compared with traditional surgery: no bleeding during and after the procedure, decontaminant effect on the surgical area, no suture, and a fast spontaneous eruption. Conclusions: The pre-orthodontic uncovering and autonomous eruption of palatally impacted maxillary canines provides simplified, predictable, and more aesthetic outcomes. Furthermore, a significant positive factor is that there is no need to carry out the orthodontic traction of the impacted element, undoubtedly better compliance by the patient during the next alignment phase with the fix orthodontic appliance.<\/jats:p>","DOI":"10.3390\/dj9060066","type":"journal-article","created":{"date-parts":[[2021,6,9]],"date-time":"2021-06-09T04:22:22Z","timestamp":1623212542000},"page":"66","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Uncovering and Autonomous Eruption of Palatally Impacted Canines\u2014A Case Report"],"prefix":"10.3390","volume":"9","author":[{"given":"Alessandra","family":"Impellizzeri","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Sciences, \u201cSapienza\u201d University of Rome, Via Caserta 6, 00161 Roma, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martina","family":"Horodynski","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Sciences, \u201cSapienza\u201d University of Rome, Via Caserta 6, 00161 Roma, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4694-7032","authenticated-orcid":false,"given":"Emanuela","family":"Serritella","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Sciences, \u201cSapienza\u201d University of Rome, Via Caserta 6, 00161 Roma, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8509-2255","authenticated-orcid":false,"given":"Gaspare","family":"Palaia","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Sciences, \u201cSapienza\u201d University of Rome, Via Caserta 6, 00161 Roma, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5115-3582","authenticated-orcid":false,"given":"Adriana","family":"De Stefano","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Sciences, \u201cSapienza\u201d University of Rome, Via Caserta 6, 00161 Roma, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2679-7607","authenticated-orcid":false,"given":"Antonella","family":"Polimeni","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Sciences, \u201cSapienza\u201d University of Rome, Via Caserta 6, 00161 Roma, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6876-8839","authenticated-orcid":false,"given":"Gabriella","family":"Galluccio","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Sciences, \u201cSapienza\u201d University of Rome, Via Caserta 6, 00161 Roma, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,9]]},"reference":[{"key":"ref_1","first-page":"28","article-title":"Early predictive variables for upper canine impaction as derived from posteroanterior cephalograms","volume":"75","author":"Sambataro","year":"2005","journal-title":"Angle Orthod."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"44","DOI":"10.1002\/cre2.246","article-title":"Prediction of maxillary canine impaction based on panoramic radiographs","volume":"6","author":"Margot","year":"2020","journal-title":"Clin.
