The orthodontic extrusion and alignment of PDCs require adequate anchorage to enable tooth movement and control the side effects. There is no paper presenting treatment in the case of severe oligodontia with simultaneous PDCs and the use of mini-implants (MIs) for their orthodontic extrusion. Case presentation: A 15-year-old patient presented with non-syndromic oligodontia and bilateral PDCs. Cone beam computed tomography revealed that both PDCs were in proximity to the upper incisors\u2019 roots. There was no evident external root resorption of the incisors. The \u201ccanines first\u201d approach was chosen. MIs were used both as direct and indirect anchorage. First, the extrusive forces of cantilevers were directed both occlusally and distally. Next, the buccal directions of forces were implemented. Finally, fixed appliances were used. PDCs were extruded, aligned, and torqued. Proper alignment and occlusion were achieved to enable further prosthodontic restorations. Conclusions: The use of MIs made it possible to avoid collateral effects, reduce the risk of complications, and treat the patient effectively. MIs provide adequate anchorage in demanding cases. The use of MIs for the extrusion of PDCs made it possible to offer this treatment option to patients with severe oligodontia. The presented protocol was effective and served to circumvent treatment limitations associated with an inadequate amount of dental anchorage and a high risk of root resorption.<\/jats:p>","DOI":"10.3390\/medicina59112032","type":"journal-article","created":{"date-parts":[[2023,11,17]],"date-time":"2023-11-17T09:10:38Z","timestamp":1700212238000},"page":"2032","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Orthodontic Treatment of Palatally Impacted Canines in Severe Non-Syndromic Oligodontia with the Use of Mini-Implants: A Case Report"],"prefix":"10.3390","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5112-6322","authenticated-orcid":false,"given":"Marcin","family":"Stasiak","sequence":"first","affiliation":[{"name":"Division of Orthodontics, Faculty of Medicine, Medical University of Gda\u0144sk, Aleja Zwyci\u0119stwa 42c, 80-210 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-1696-8562","authenticated-orcid":false,"given":"Aleksandra","family":"Ko\u0142odziejska","sequence":"additional","affiliation":[{"name":"University Dental Center of Medical University of Gda\u0144sk, D\u0119bowa 1a Street, 80-204 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3709-3576","authenticated-orcid":false,"given":"Bogna","family":"Racka-Pilszak","sequence":"additional","affiliation":[{"name":"Division of Orthodontics, Faculty of Medicine, Medical University of Gda\u0144sk, Aleja Zwyci\u0119stwa 42c, 80-210 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,17]]},"reference":[{"key":"ref_1","unstructured":"Adam, M.P., Everman, D.B., Mirzaa, G.M., Pagon, R.A., Wallace, S.E., Bean, L.J., Gripp, K.W., and Amemiya, A.
