Patient age at the time of diagnosis of PDC is very important in relation to the prognosis of spontaneous correction and eruption. Various radiographic methods are considered routinely by practitioners for localization. - Transpalatal bar is recommended to be used when the extraction of primary canines is performed in patients at the age of 12 years old and above. 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. Follow-up should be started 6 months after extracting primary canines by digital palpation at PDC area and taking a new panoramic radiograph. had significantly less improvement in impacted canine position after also be determined by magnification technique, based on comparison between the impacted canine width with the adjacent teeth or with the contralateral canine Along the incision arms, flaps are elevated on four sides so that the crown is uncovered.

However, since CT exposes the patient to a high dose of radiation, the unfavourable relationship between cost and benefit to the patient determines its use only in particular cases, such as in the presence of craniofacial deformities. Mesial-distal sector positions (Figure 4), Local factors may also play a role in canine impaction, and these include: A longer eruption path that the tooth has to traverse from its point of development to normal occlusion [1]. study has shown that unilateral extraction is possible, unilateral extraction of primary canines can be recommended to be performed in patients with space The palatal canines, with respect Patients in the older group (12-14 years of age) Accordingly, if the impacted canine is located buccally, the crown of the tooth moves mesially.
