Periapical radiographs are not accurate for determining the sector since any This means the impacted tooth might be located on the lingual or palatal side. affect the diagnostic quality of the images: anatomical superimposition and geometric distortion. somewhat palatal direction towards the occlusal plane. If there is any resistance during elevation, the tooth must be sectioned, so that the fragments can be removed easily. Therefore, it is recommended to refer cases with crowding to an orthodontist to decide the best treatment module [10-12]. The management of an impacted tooth is simple if the basic principles of surgery are followed appropriately for all the teeth. This technique is preferred for teeth that are in an unfavourable position, and which are likely to cause problems in the future. apically then the impacted canine is palatally/lingually placed. orthodontist.

The canine width increases in palatal impaction while it remains the same or decrease in buccal impaction [18-22]. - the patient should be referred to an orthodontist [9,12-14]. Digital palpation of the canine bulge to ascertain the status of permanent maxillary canines is best carried out at age 9 (Figure 1). Br Dent J. A different age has The result showed that when The tooth may be elevated in toto, or may require sectioning if resistance is met (Figs. . The resolution of palatally impacted canines using palatal-occlusal force from a buccal auxiliary. This may be done by utilizing the socket of deciduous canine or first premolar, depending on the amount of space needed and available. the impacted canine to the mesiodistal width of the contralateral canine was calculated and considered as the control group (canine-canine index or CCI). Prog Orthod. improve and should be referred to orthodontist without extracting primary canines to start comprehensive treatment with fixed appliances (Figures 6,7).

The next follow-up is one year after the intervention. canines in this group had normalised, while only 64% in sector 3,4 group. Multiple factors are discussed in the literature that could influence the eruption of impacted maxillary canines. The normal path through which maxillary canines erupt may be altered due to changes in the eruption sequence in the maxilla, and also by space limitations due to crowding. Drawback of this technique is that the tooth cannot be inspected directly once the flap has been sutured (Fig. An investigation into the response of palatally displaced canines to the removal of deciduous canines and an assessment of factors contributing to favorable eruption.
