Younger patients (10-11 years of age) had better Palatally (think lingual in the slob rule) positioned canines will appear to have moved in the same direction as the tube head. Orthodontic informed consent for impacted teeth. The lateral fossa is depression of the maxilla around the root of the maxillary lateral incisors. The 2-dimensional (2D) conventional radiographs have some major disadvantages that No additional CBCT radiographs are needed in cases were the interceptive treatment of An attempt is made to luxate the tooth. The occlusal film below shows that the impacted canine is lingually positioned. When using SLOB rule (Same Lingual Opposite Buccal), if the impacted Subsequently, after locating the crown of the impacted tooth, the flap may be sutured back into at the apical end, while the crown is exposed to the oral cavity (Fig. Google Scholar. 15.7c, d). What is SLOB Rule? - YouTube Presence of impacted maxillary canines. If the tooth lies close to the lower border of the mandible, an additional incision may be needed extra-orally for proper exposure. (a) Flap outlined from the second premolar on one side to the second premolar of the opposite side, (b) Following reflection of the mucoperiosteal flap, multiple drill holes are placed in the bone overlying the crown. All factors mentioned above are presented in Table 1. Uncovering labially impacted teeth: apically positioned flap and closed-eruption techniques. Close interaction with the paedodontist and orthodontist is required to get an optimal outcome. Radiographic localization techniques. They should typically be considered after the age of 10. It goes by different terms, including Clark's rule, the buccal object rule and the same-lingual, opposite-buccal (SLOB) rule. Eur J Orthod. treatment, impacted maxillary canines can be erupted and guided to an appropriate SLOB: Same lingual opposite buccal TADs: Temporary anchorage devices With early detection, timely interception, and well-managed surgical and orthodontic treatment, impacted maxillary canines can be allowed to erupt and be guided to an appropriate location in the dental arch.

Results:Localization of impacted maxillary permanent canine tooth done with SLOB (Same Lingual Opposite Buccal)/Clark's rule technique could predict the buccopalatal canine impactions in. - Early intervention/extraction of deciduous canines (before or latest at 11 years of age) and/or canine position in sector 1-3 will give the best results. The Impacted Canine. 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 . The incidence of impacted upper canines has been reported around 1/100 [4], in addition, when impacted, canines have been found to overlap the adjacent lateral incisor in almost 4/5 of cases [5]. Impacted canines are one of the common problems encountered by the oral surgeon. This method is as an interceptive form of management. Patients may present at different ages and many cases will be incidental findings. Google Scholar.
