The aim of our study is to evaluate, through a systematic review, the bone capital of the maxillary impacted canines vestibular or palatine trailed compared to their contralateral counterpart. Method: five databases were consulted: PubMed; PubMed Central, Google Scholar, Cochrane Library, and Ebscohost. The research included published studies from 2010 to 2018, meta-analysis studies, randomized and non-randomized controlled trials, prospective and retrospective studies, case series, control

... s. Results: Among the 299 selected references, only 4 studies met our inclusion criteria. There is no statistically significant difference in alveolar bone loss between the two closed and open techniques for palatal canine traction. Bone loss ranged from 0.03 mm to 0.39 mm compared to the contralateral normal canine. For vestibular traction, bone resorption compared to the normally located canine varies from 0.82 to 0.89 mm. Conclusion: Canine traction is accompanied by a statistically significant bone loss compared to the contralateral canine. This bone defect is more aggravated when the inclusion is vestibular but remains clinically acceptable.
