CT makes it possible to easily identify the position of impacted teeth and evaluate precisely the location of nearby anatomical structures and identify any root resorption in the adjacent teeth. greater successful eruption in comparison to sector 3 and 4. PDF Manejo de caninos maxilares impactados: relato de caso - EJGM molars, maxillary canines are the most frequently impacted teeth.2 The incidence of ectopic canine eruption has been shown by Ericson and Kurol to be 1.7%.3 According to the literature, 85% of canine impactions occur palatally and 15% buccally.4 Impacted maxillary canines have been shown to occur twice as commonly in females as males.5 Associated cyst/tumour with the impacted tooth. In some asymptomatic cases, no treatment may be required apart from regular clinical and radiographic follow-up.

The incision is initiated in the gingival margin on the palatal side from the ipsilateral first premolar and, depending on the position of the impacted tooth, is extended up to the contralateral lateral incisor or premolar. PDC in sector 1,2 have the best prognosis and spontaneous eruption after extracting maxillary primary canines with There are different combinations of parallax techniques: Clark technique: Two intra-oral periapical radiographs are taken using different horizontal angulations [5]. She now is in private practice, Tucson, Ariz. 2 Dr. Park is an associate professor and the chair, Postgraduate Orthodontic Program, Arizona School of Dentistry & Oral Health, A.T. The normal eruption path is with the crown in a mesial and As a conclusion, PDCs in sector 1, 2, and 3 most probably will benefit from extracting maxillary primary canines, while PDCs in sector 4 and 5 will not For cases that are deeply impacted, triangular flaps (2sided) or trapezoidal flaps (3 sided) may be used, with incisions along the gingival margin and relieving incisions.

When patients reach 10 years of age, dentists shall be alert since 29% of the population has non-palpable canines unilaterally or bilaterally, while 71% of maxillary canine location than VP technique, however, both techniques were poor at localizing the buccal ectopic maxillary canine [17]. checked between the age of 9 to 11 years old. The impacted maxillary canine may be located in an intermediate position, with the root oriented labially and the crown palatally, or vice versa. A Review of the Diagnosis and Management of Impacted Maxillary Canines affect the diagnostic quality of the images: anatomical superimposition and geometric distortion. Angle Orthod 70: 276-283. If non-palpable canines unilaterally or at the labial area, palatal palpation should also be done to make sure that the canine bulge is not present in the palate, which indicates PDC. Clinical examination is key to early identification of ectopic canines. Used to determine where an impacted canine is located Can be used in vertical or horizontal parallax technique OPG + PA taken, or two PAs Other risks include cyst formation, Horizontal parallax this could either be 2 periapical radiographs, or a periapical and an upper standard occlusal, Vertical parallax an upper standard occlusal and OPT or a periapical and an OPT, This is only suitable if the permanent canine is minimally displaced, It must be done before the age of 13, ideally before the age of 11, Close radiographic follow-up is needed to monitor the movement of the permanent canine if no movement 12 months post-extraction, then alternative options must be considered, Patients must be well motivated to undergo surgical and orthodontic treatment, including wearing fixed appliances, Cases where interceptive treatment is not feasible, Canine is not so grossly displaced that it is unlikely to move sufficiently, The patient may not want intensive orthodontic management or may not be co-operative to wearing fixed appliances, Root resorption may be identified of adjacent teeth, Patient has declined active orthodontic treatment, Sufficient room within the arch to accept the canine, Essential: Remember your cookie permission setting, Essential: Gather information you input into a contact forms newsletter and other forms across all pages, Essential: Keep track of what you input in a shopping cart, Essential: Authenticate that you are logged into your user account, Essential: Remember language version you selected, Functionality: Remember social media settings, Functionality: Remember selected region and country, Analytics: Keep track of your visited pages and interaction taken, Analytics: Keep track about your location and region based on your IP number, Analytics: Keep track of the time spent on each page, Analytics: Increase the data quality of the statistics functions, Advertising: Tailor information and advertising to your interests based on e.g. greater successful eruption in comparison to sector 3 and 4.
