“…Each digital panoramic radiograph was measured using image J as follows ( Figure 2): Angle: Angle created by the long axis of the palatally impacted canine to the midline constructed on the OPG 13,27,28 Horizontal: Linear horizontal distance of the palatally impacted canine cusp tip to the midline constructed on the OPG Vertical: Linear vertical distance of the palatally impacted canine cusp tip to the occlusal plane constructed on the OPG using the mesial-buccal cusp of the first molar and the incisal distal margin of the maxillary central incisor 12,15,27 Data from the experimental and control groups were subgrouped from least deviated (subgroup 1) to most deviated (subgroup 3) according to impaction condition (Table 1).…”

Objectives: To compare forced-eruption times for palatally impacted canines treated with and without the ostectomy-decortication technique and to assess the influence of palatally impacted canine pretreatment position and angle on forced-eruption time. Materials and Methods: The sample was composed of 118 patient-subjects with 151 palatally impacted canines treated with the ostectomy-decortication technique (n = 72) and without (n = 79). The orthopantomogram radiographs (OPGs) were analyzed for palatally impacted canine angle and horizontal and vertical position. Recovery time was measured from the start of forced eruption until the canine was within ±1 mm of final dental arch position. Results: The time of forced canine eruption with ostectomy-decortication technique was significantly shorter than without (6.6 vs 21.0 months). Pretreatment canine position significantly increased forced-eruption time in the ostectomy-decortication group but not in the control sample. Conclusions: Forced-eruption time of palatally impacted canines using the ostectomy-decortication technique was 3.2 times more rapid than without. Forced-eruption time increased significantly as a function of pretreatment palatally impacted canine position severity in the ostectomy-decortication group but not in the control.

“…20 The angulations and position of the canines in the dental arch, the overlap between the lateral incisor and canine and the presence of root anomalies have all been discussed as having a role in the treatment decision. 18,21,22 Using low-dose cone beam CT (CBCT) images to assess the impacted canine in a three-dimensional (3D) representation has shown clear benefits for both diagnosis and prognostic estimates on eruption as well as treatment planning. [23][24][25][26] Most studies have compared conventional radiology and CBCT, showing a superiority of CBCT in assessing the exact position of impacted canines.…”

“…Johnson stwierdził, że postępowanie ortodontyczne w przypadku przedsionkowo położonych kłów szczęki jest wielokrotnie trudniejsze niż w przypadku ich podniebiennej pozycji i jest obciążone dużym ryzykiem niepowodzenia (41). W przypadkach podjęcia leczenia ortodontycznego konieczna jest dokładna ocena pozycji abnormal root anatomy and likelihood of effective canine movement into the dental arch (36). Bishara states that serious root angulation or damage to tissues of a canine that stays in the bone are contraindications for its removal (Fig.…”

Orthodontic movement of a maxillary canine into the dental arch may be a therapeutic challenge, and it is necessary to analyse a case in detail and to evaluate therapeutic methods, including a difficult decision of tooth extraction in all cases. Aim. The paper aims to discuss orthodontic indications for maxillary canine extraction based on available literature. Material and methods. The PubMed database and the following key words were used for studies: canine impaction, maxillary impacted canine and canine extraction. Literature was supplemented with publications from reviewed journals not included in the PubMed database. 50 papers were selected from the literature list. Results, review and discussion. A decision to extract a maxillary canine should be made based on a detailed clinical examination and analysis of orthodontic records, including photographs, diagnostic models and radiological scans. CBCT imaging test should be performed as standard before treatment in case of impaired tooth eruption. Factors that should be especially considered include: tooth anatomy, periodontal status, position in the bone, occlusion, condition of the adjacent teeth and any pathological processes in the tooth vicinity. Before making a therapeutic decision a patient should be informed about available therapeutic options according to current medical knowledge, as well as about advantages and disadvantages of each of them. Summary. Factors favouring extraction of impacted canines or canines with impaired eruption include: unfavourable position (a horizontal position of a tooth in the bone, position in the zone IV and V according to Kurol, large distance from the edge of the alveolar process), anatomical abnormality (root angulation, external or internal resorption), root ankylosis, patient’s age above 30 years and good occlusion without a canine in the dental arch with the need to extract a premolar for its movement into the dental arch.
