Objectives: Review the literature on radiographic predictors and extraction of the deciduous canine to intercept impaction of the upper permanent canine, and subsequently, evaluate a sample. Methods: Literature review and observational study using radiographic predictors, in horizontal and angular direction, in a sample of 10 orthodontic patients, with a radiographic follow-up of one case. Results: The extraction of primary canine with the objective of redirecting the eruptive path of the successor element is indicated when it is located, by panoramic radiography, in sector 2 with angulation equal to or greater than 20º to 30º; in sector 3; in sector 4 with angulation equal to or less than 20º to 30º. The sample comprised an evaluation of 20 maxillary canines, 30% of which had indication for the interceptive conduct. In one of the cases, element 13 was located in sector 2 (limit with sector 3) with a 29º angulation, therefore, extraction of element 53 was performed and a year later the redirection of the eruptive path of element 13 could be identified radiographically. Conclusions: In the present sample, 30% of the canines had an indication of extraction of the deciduous predecessor, and in the accompanied case, the benefit of the interceptive procedure regarding impaction was observed.
