Abstract: Impaction of maxillary canines can be prevented by early intervention in the mixed dentition phase after the correct diagnosis of malocclusion, reducing the complexity of the treatment. This article reports the case of a 10-year-old patient who possessed impacted maxillary canines and, after early extraction of primary canines, had reestablished favorable permanent successors' eruption axis. This 5-year radiographic follow-up study with panoramic radiography shows that this can be used in practice and that an … Show more

“…direct correlation was found between age and severity of impaction. Once the roots have completely formed the frequency of eruption decreases 36. However, orthodontic intervention might prolong this window of natural eruption.…”

Objectives The objective of the study was to quantify the 3‐D location of impacted canines by measuring their linear and angular deviations in relation to adjacent structures and further evaluate impaction severity. Methods CBCT images of 314 impacted canines were analysed in the sagittal, coronal and axial planes. Linear and angular measurements were recorded. Canine inclination was identified in coronal and sagittal planes. An evaluation system was constructed for analysis. Upright canine was considered as the appropriate position for fully erupted maxillary canine. Outcomes were compared between right and left sides and by gender. For categorical variables, chi‐square tests were used while Mann‐Whitney U test was used for continuous variables. Regression models were used to measure severity. Results Impactions were greater in females (119/207; 57.5%). No significant differences between unilateral (100/207; 49.3%) and bilateral (107/207; 51.7%) (P > 0.05). Out of 314 impactions, 105 (33.4%) were mild, 118 (37.58%) moderate and 91 (28.98%) severe. Severe impactions were primarily buccal (44/ 91; 48.3%), in the occlusal ½ of the adjacent incisor root (38/ 91, 41.7%), mesial to the distal border of central incisor (47/91, 51.6%), with sagittal angle value + >45 ̊ (46/ 91, 50.5%) and mesial tip + >30 ̊ (86/ 91, 94.5%). Conclusions Severely impacted canines had their crowns buccal, closer to occlusal plane and mesial to the distal border of the central incisor with greater than 45‐degree buccal inclination and greater than 30‐degree mesial tip. The sagittal angle can have a significant impact on the severity of impaction. A new classification system was proposed to quantify severity.

Maxillary canines are the most commonly impacted teeth following third molars. Considered as the cornerstone of the dental arch, appropriate treatment of these impacted canines should be applied in order to maintain the function and esthetic integrity. Labially impacted canines are not uncommon in Asian countries, and it is often challenging to manage them without the esthetic or periodontal consequences. The apical positioned flap (APF) is one of the periodontal procedures that has been proposed to expose labially impacted canines. The APF technique can provide adequate attached gingiva, good visibility and faster canine retraction during orthodontic treatment; however, it is technique-sensitive. Therefore, in this article, two cases of labially impacted maxillary canines treated with an APF and orthodontic treatment are presented, and the keys to successful treatment outcomes in periodontal perspectives are discussed.
