Patients in group 1 had 85.7% successful canine eruption, 82% in group 2 and 36% in the untreated control group [10]. 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 Possible indications and requirements include: Ideally, this should be carried out prior to complete root formation. primary canines is performed in those cases, the crowding most probably will be solved by the movement of the adjacent teeth into the extraction space, On the other hand, patients at 12 years old of age and above show a significantly less response to interceptive treatment [9,12-14]. CAS eruption in comparison to older patients (11-12 years of age). T wo periapical films are tak en of the same area, with the . 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 However, they may occasionally migrate to the mental protuberance or even the lower border of mandible, where they can lie in a transverse position. More developed root at the time of eruption, which may minimize the eruptive force. problems may arise such as root resorption of maxillary lateral and central incisors, high cost and long treatment time, and migration of adjacent teeth with This chapter elaborates on canine impaction, keeping in mind the basic principles mentioned in the chapter on third molar impactions. This technique may be used in cases where there is enough space for the canine to erupt, and where the root formation is incomplete. in relation to a reference object (usually a tooth). - 209.59.139.84. surgical and orthodontic management) used to prevent or properly treat impacted canines. Tooth sectioning (odontotomy) may be carried out using a straight fissure bur if there is any obstruction to movement (Fig. The chosen method would depend on the degree of impaction, age of the patient, stage of root formation, presence of any associated pathology, dental condition of the adjacent teeth, position of the tooth, patients willingness to undergo orthodontic treatment, available facilities for specialized treatment and patients general physical condition. The use of spiral computed tomography in the localization of impacted maxillary canines. impacted canine area shall be referred directly to the orthodontist without any extractions or interventions from the general dentist to avoid unnecessary Orthodontic reasons, such as the need to move an adjacent tooth into the area of impaction. 3 , 4 The incidence of canine impaction in the maxilla is more than twice that in the mandible. Elevation of a single palatal flap not only avoids sloughing but also provides adequate visualization. 15.11ai) shows the localisation and surgical removal of a labially positioned impacted maxillary canine. According to Clark's rule (SLOB), if the image shifts from the position of taking panoramic radiograph to the position taking occlusal radiograph, a. The VP technique requires panoramic and anterior occlusal radiographs [15,16]. of the cases at this age, surgical exposure followed by orthodontic traction of the canines is indicated [2,12]. Any one of the following techniques may be employed depending on the depth and position of the impacted tooth: Creating a surgical window/Gingivectomy: This is done if the tooth lies just underneath the gingiva. According to this, for a given focal spotfilm distance, objects that are far away from the film will appear more magnified than those that are closer to the film.

No difference in surgical outcomes between open and closed exposure of palatally displaced maxillary canines. This method can be applied effectively only when the canine is not rotated, does not touch the incisor root and the incisor is not tipped [11]. treatment, impacted maxillary canines can be erupted and guided to an appropriate Surgical Techniques for Canine Exposure. recommended to be taken when it will make a change in the treatment plan.

PubMed Chaushu et al postulated that if the ratio of the canine to the central incisor is greater than or equal to 1.15, the canine is likely palatally positioned.11 Third option is to look for canine superimposition on the root of the central incisor, as proposed by Wolf and Mattila.12 As per their rule, if impacted maxillary canine is superimposed .

Out of 50 impacted canines, 17 (34 %) were located bucally, 32 (64 %) palatally, and 1 (2 %) in the arch. 2005 Mar;63(3):3239. Figure 3: Different Types of Radiographs None of the authors reported any disclosures. A buccal flap must ideally be used for surgical access, as a lingual flap may not provide adequate access, and is associated with increased post-operative morbidity. Read More. Tooth or root displacement into the maxillary sinus. Notify me of follow-up comments by email. Patient age at the time of diagnosis of PDC is very important in relation to the prognosis of spontaneous correction and eruption.

Use of panoramic X-ray to determine position of impacted maxillary canines. approximately four times more than the panoramic radiograph [33]. time-wasting and space loss. 5). If three fragments are created, the middle one may be removed first, and the remaining two fragments may be elevate using the resultant space (Fig. of the patients in this study had exfoliated maxillary deciduous second molars [10]. The SLOB (Same Lingual - Opposite Buccal) rule helps to remind the dental operator that when the tube head is shifted mesially, the lingual or palatal root will also be shifted mesially (in the same direction as the shifted tube head) on the developed film and the buccal or mesiobuccal root will be shifted distally (in the opposite direction .
