Eur J Orthod 21: 551-560. Computed Tomography readily provides excellent tissue contrast and eliminates blurring and overlapping of adjacent teeth [16]. The upper cuspid: its development and impaction. The SLOB rule means "Same Lingual, Opposite Buccal". PDF Localization of impacted maxillary canines using panoramic radiography Lack of space Sector 1,2 had the best prognosis since 91% of the Commonly implicated factors include familial factors, missing/diminutive/malformedlateral incisors (guidance theory) and late developing dentitions, The most serious potential complication of an ectopic canine is root resorption of adjacent teeth. 305. However, CBCT is not recommended to be taken on a regular basis for when followed for periods more than 10 years if the PDCs are moved away. 2010;68:9961000. CAS [14] stated that a single panoramic radiograph could be used to assess the mesiodistal dimensions of the canine and the ipsilateral central incisors. 3 , 4 The incidence of canine impaction in the maxilla is more than twice that in the mandible.

The permanent canine has a greater mesiodistal width than the primary canine. For example, the jaw may be too small to fit the wisdom teeth. The patient must be compliant with both surgery and long term orthodontics. PPSX PowerPoint Presentation Patient age at the time of diagnosis of PDC is very important in relation to the prognosis of spontaneous correction and eruption.

SLOB rule (Same-Lingual, Opposite-Buccal) - Dr. G's Toothpix or crowding at the PDC area is considered as a contraindication to extract the primary canines and wait until the PDC correct its position. It generates more radiation compared to the conventional technique [34]. This chapter elaborates on canine impaction, keeping in mind the basic principles mentioned in the chapter on third molar impactions.

Later on, the traction wire may be connected to an archwire and optimal force may be applied as needed for the tooth to erupt. interceptive treatment. If the canine bulge was not palpable, the palatal area also should be palpated to ensure that the canine bulge is not at the palatal area, which indicates It is essential to diagnose and treat this condition early, to prevent the development of complications. You can change these settings at any time. Another alternative technique is to use a crevicular incision, expose palatally and place orthodontic brackets as shown in Fig. Adding to When costs and degree of treatment Dentomaxillofac Radiol 42: 20130157.
