“…The differences found in this study for the number of male and female patients (ratio 1:1) and the frequency of unilateral and bilateral impactions (60% and 40% respectively) from what’s described in literature ( 6 , 9 ), might be explained by the reduced sample size.…”

BackgroundThe use of CBCT exam in the study of IMC is not new. However, it’s still not known in what specific aspects CBCT exam shows a better result than then conventional exams. The aim of this study was to compare and conclude in what way the opinion regarding upper canine impaction differed when observing a panoramic image compared to the observation of a set of CBCT reconstructions.Material and MethodsTwenty patients (10 males and 10 females) with a total of 28 impacted maxillary canines were identified from the database of the Department of Dentistry, Faculty of Medicine, University of Coimbra. For each canine, two different images were available: a panoramic image and a set of CBCT reconstructions. After a random distribution of both groups images, nine orthodontists completed a questionnaire where they were asked to evaluate ten different questions regarding canine impaction. Statistic analysis was performed using Cronbach’s alpha statistics, Kappa statistics and McNemar test, considering p<0,05 statistically significant.ResultsThis study showed differences between the two images regarding tooth position. A statistical significant poor agreement was found between the two methods for the mesio-distal position of the apex (k=0,388, p<0,001) and for the labio-palatal tip cusp position (k=0,035, p=0,114). The adjacent root resorption showed a poor and very poor agreement between the two methods. Every other items were scored with an agreement between modalities ranging from moderate to strong.ConclusionsThe analyses of panoramic images versus CBCT images reconstructions provided different information regarding tooth position (especially concerning the mesio-distal apex position and the labio-palatal cusp position) but also in the assessment of root resorption. Further investigation should be done to determine in what cases CBCT exam has a clear advantage over conventional 2D exams, justifying its use. Key words:Cone-Beam Computed Tomography, Orthodontics, Impacted Tooth, Root resorption.

“…The recognition of tooth disturbances in early mixed dentition that are genetically associated with canine impaction can aid clinicians in the early diagnosis of this clinical situation. If the canine displacement is detected early, the clinician should then focus on preventing potential impaction; however, it is more common for the orthodontist to first encounter the impaction after it has become problematic, 5 as in the presented clinical case.…”

“…These techniques are commonly used due to availability and ease of determining the prognosis of an impacted canine. 5 The management of severely impacted canines often requires the combined expertise of numerous clinicians who communicate with each other to generate an optimal treatment plan. The surgical, periodontal, and orthodontic considerations in the management of impacted canines must be clearly explained to the patient.…”

Aim: The aim is to report a case of impacted maxillary right canine successfully positioned into the occlusion line. Background: Although the treatment of choice for an impacted canine is a combined surgical-orthodontic approach, there are differences in technique. The preorthodontic uncovering and autonomous eruption technique is a safe and predictable option for the treatment of palatally impacted maxillary canines in adolescents and adults as is the orthodontic creation of a space before minimal surgical exposure, the bonding of a small attachment (an eyelet), full-flap closure, and immediate traction. Although the mechanical management of impacted teeth is a routine task for most orthodontists, certain types of impaction can be frustrating. Case description: An 18-year-old adult patient presented for clinical examination with a mobile maxillary right deciduous canine, the absence of a maxillary right permanent canine, Angle Class I malocclusion, an overjet of 2.0 mm, an overbite of 3.0 mm, and rotated canine and left maxillary central and lateral incisors. Cephalometric measurements revealed a skeletal Class I relationship as well as upright maxillary incisors (1. NA = 18º) and mandibular incisors (1. NB = 16º, IMPA = 80º). The facial profile was concave. Clinically, a constricted maxillary arch was observed, and the patient had a nail-biting habit. Conclusion: The canine was aligned, leveled and positioned in the occlusion line. The aesthetic, functional and periodontal results remained stable in the retention phase. Clinical significance: Various treatment strategies are available to treat impacted maxillary canines. The surgical, periodontal, and orthodontic considerations in the management of impacted canines must be clearly explained to the patient.

“…Typically, the location of impacted canines is classified into two categories, i.e., a buccal or palatal impacted canine [1–6]. However, in a smaller percentage (approximately 6.6%) of cases, the canines may be impacted in the middle of the alveolar process [7] or precisely between the two cortical bones (bicortical) and cannot be classified as a buccal or palatal canine [8, 9].…”

Three-dimensional evaluation of the root resorption of maxillary incisors after the orthodontic traction of bicortically impacted canines: case reports

et al. 2019

Background The root resorption of the maxillary incisors after the orthodontic traction of impacted canines is a concern for clinicians. The aim of this case series report was to evaluate the root resorption of the maxillary incisors after traction until the occlusal plane of the bicortically impacted canines (placed between the two cortical bones in the middle of the alveolar process) located in a complex position using three-dimensional superimposition. This case series report describes the root resorption of the maxillary incisors after orthodontic traction with NiTi closed coil springs and a heavy anchorage appliance in three cases of bilateral impacted canines located in a complex position (bicortically) near to midline. Cone-beam computed tomographies (CBCTs) were obtained before and after traction. Root resorption in all root surfaces of the maxillary incisors was evaluated with color-coded maps using the ITK-SNAP and the 3D Slicer software to indicate loss of the root surface (in red) or gain of the surface (in blue) and was quantified in millimeters by the superimposition method. Results The root changes mainly occurred in the apical third of the maxillary incisor root and did not exceed 2 mm. Conclusions Root resorption of the maxillary incisors after the traction of bicortically impacted canines located in a complex position was observed mainly in the apex region, and the amount of root resorption was smaller than 2 mm in all root surfaces.
