On the other hand, if the PDC position worsens in relation to sector or angulation, greater successful eruption in comparison to sectors 4 and 5. Expert solutions. They usually develop high in the maxilla and need to travel a considerable distance before they erupt. On the other hand, if the canine moves to the opposite direction, it indicates buccal canine position. Younger patients (10-11 years of age) had better Relation Between Canine Cusp Tip and Along the incision arms, flaps are elevated on four sides so that the crown is uncovered. that, the technique is inaccurate and difficult to apply if the impacted canine is rotated or it is in contact with incisor root [20].

Ericson S, Kurol J (1986) Longitudinal study and analysis of clinical supervision of maxillary canine eruption. As the buccal object rule states that the buccally located object moves in the direction of the x-ray beam, on changing the direction of x-ray beam, the position of the impacted canine can be determined.

The radiographic interpretation of the SLOB rule is if, when obtaining the second radiograph, the clinician moves the x-ray tube in a distal direction, and on the radiograph the tooth in question also moves distally, then the tooth is located on the lingual or palatal side. Disorder of the primary canine can affect the position of the permanent one. To read this article in full you will need to make a payment. The apical third and palatal surface were commonly involved.
