Subjects. bilaterally exist, it is indicated to take diagnostic radiographs. 1 Dr. Bedoya was a postgraduate orthodontic resident, Postgraduate Orthodontic Program, Arizona School of Dentistry & Oral Health, A.T. It gradually becomes more upright until it appears to strike the distal aspect of the root of the lateral Disclosure. Canine impaction is a common occurrence, and clinicians must be prepared to manage None of the authors reported any disclosures. Showing Incisors Root Resorption. Southall and Gravely technique: One maxillary anterior occlusal radiograph and one maxillary lateral occlusal radiograph are taken [6]. Note the close relationship of the root of the impacted canine to the floor of the maxillary sinus and nose. The incisors had different types of resorptions ranging from mild to severe with pulpal involvements. treatment. 1. Alternately, a horizontal incision may be made below the attached gingiva. in 2012 have brought out a useful classification of maxillary canine impactions based on which the exposure technique may be decided [25]. If the root is >75% formed, the likelihood of requiring root canal treatment increases. Cookies Extraction of impacted maxillary canines with simultaneous implant placement. and the other [2]. This may be the appropriate option if a patient does not want any treatment and is happy with their appearance. greater successful eruption in comparison to sector 3 and 4. Opposite Buccal What . Systemic Antibiotics for Periodontal Diseases, Removable Partial Dentures: Kennedy Classification, Typically, canines should be palpated at 9-10 years of age, and should erupt a few years later, Prevalence of between 1-3% (second to impacted mandibular third molars), 3:1 ratio of palatal to buccal impactions (<10% bilateral), Aetiology likely to be multifactorial. Fifty per cent of the resorptive lesions were mild, 20% moderate and 30% severe. Rayne technique: This involves differing vertical angulations, with one periapical and one maxillary anterior occlusal radiograph being taken [7]. Most of the evidence and information discussed in this review were gathered and transferred into decision trees (Figures 8-12). As a general rule, alpha angle less Periapical radiographs are not accurate for determining the sector since any Oral Surg Oral Med Oral Pathol Oral Radiol. Pretreatment, 6 and 12 months panoramic radiographs should be compared together, if the PDC position improved, a follow-up This was first introduced by Clark [5], and involves two radiographs taken at two different horizontal angles, but using the same vertical angulation. Presence of associated cyst, odontomas or supernumerary teeth. The final factor that influences the eruption of PDC after interceptive treatment is the space available at the PDC area before extraction. Radiographic examinations may include periapical X-ray with cone shift technique, occlusal radiography, anteroposterior and lateral radiographic views of maxilla, OPG, CBCT, CT scan. Localizing the impacted canine seems not a challenge any more with the advent of CBCT, in indicated cases. self-correction. 15.3). All factors mentioned above are presented in Table 1.

(Currently we do not use targeting or targeting cookies), Advertising: Gather personally identifiable information such as name and location. Localization of impacted maxillary canines and observation of adjacent incisor resorption with cone-beam computed tomography. Dent Pract. On the other hand, PDCs in sector 3 and 4 have a lower success rate, which equals 64% [9]. Infrequently, this bone may be absent. Surgically exposing the crown of the canine may allow it to come into position by normal eruptive forces. Still University, 5855 East Still Circle, Mesa, Ariz. 85206. Treatment planning requires a multidisciplinary approach, and the general dental surgeon must consult with the oral and maxillofacial surgeon, orthodontist and paedodontist for achieving optimal results. Note the relationship of the cuspid to the roots of the adjacent teeth, nasal cavity and maxillary sinus. What the Patient Should Expect at the Orthodontist Developmental displacement of the crypt of the canine Canines have a long path of eruption Peg shaped/short-rooted/absent upper lateral incisor creates a lack of guidance for the canine to erupt Crowding Retention of primary canine Trauma to maxillary anterior area at an early stage of development Genetics See also Unerupted Maxillary Incisors Palatally ectopic canines: closed eruption versus open eruption. Notify me of follow-up comments by email. mentioned below: - One of the maxillary canines is not palpable buccally above the roots of the maxillary primary canine and there is a difference of 6 months between one side 1935;77:378.

Fox NA, Fletcher GA, Horner K (1995) Localising maxillary canines using dental panoramic tomography. In Essential Orthodontics, Eds: Wiley Blackwell Oxford UK. This is managed by splinting the lateral incisor to the adjacent tooth. The smaller alpha angle, the better results of J Periodontol. This chapter elaborates on canine impaction, keeping in mind the basic principles mentioned in the chapter on third molar impactions. Prog Orthod 18: 37. Figure 5: Angulation (Alpha Angle): Angle Between The Long Axis of The (e) Intra-oral view, (f) Mucoperiosteal flap reflected, (g) Overlying odontome exposed, (h) Odontome removed and crown of 33 exposed. PDC pressure should be evaluated. Eur J Orthod 10: 283-295. Division of the nasopalatine vessels and nerve may be done for further exposure. A different age has [10]). help erupt impacted canines, these treatment modalities have a high degree of difficulty Angle Orthod. Management of Impacted Canines | SpringerLink Apically positioned flap: In cases where the cervical portion of the crown does not lie within the attached gingiva, removal of the soft tissue may cause the attached gingiva to be lost. No votes so far! In a recent study, the amount of resorption on the roots of primary canines was investigated. Ectopic canines are most commonly involving the maxilla. Quirynen M, Op Heij DG, Adriansens A, Opdebeeck HM, van Steenberghe D. Periodontal health of orthodontically extruded impacted teeth. In situations where there is bilateral canine impaction and both teeth are close to the midline, the incision should always extend between the first or second premolars of both sides (Fig. degrees indicates need for surgical exposure (Figure Diagnosis of maxillary canine impaction may be made by clinical examination and by radiography. The HP technique is considered as a superior approach to determine Palatally (think lingual in the slob rule) positioned canines will appear to have moved in the same direction as the tube head. In 47% of the patients, the canines were unilaterally or bilaterally unerupted or non-palpable. Al-Okshi A, Lindh C, Sale H, Gunnarsson M, Rohlin M (2015) Effective dose of cone beam CT (CBCT) of the facial skeleton: a systematic review. In this review, diagnosis and interceptive treatment of PDC will be focused on and explained according to the latest evidence. Two RCTs investigated the space loss after extraction of primary maxillary canines [10,12]. They selected only studies that pertained to the prevalence, etiology and canines. Google Scholar.

This chapter elaborates on canine impaction, keeping in mind the basic principles mentioned in the chapter on third molar impactions. coronally then the impacted canine is labially placed. permanent maxillary canines are still non-palpable or erupted [2]. 15.7c, d). Other treatment suggested a technique that used a horizontal line that extended from the mesiobuccal cusp tip of the right and left maxillary first molars, along the long axis of the impacted canines. mesial or distal movements of the x-ray beams will lead to a change of canine sector position as what happens in horizontal parallax techniques. Tell us how we can improve this post? The flaps may be excised. PDF Localization of Impacted Maxillary Canine Teeth: A Comparison between In such a case, it may be better to use an apically repositioned flap. eruption in comparison to older patients (11-12 years of age). 50% of patients should have normally erupted or palpable canines at this age, and this is the accurate age to start digital palpation of maxillary canines [2]. incisor or premolar.
