Ortho Case 3.1

A 13-year-old female presented with a class I malocclusion on a mild skeletal class II pattern with average vertical dimensions complicated by moderate upper arch crowding, palatal displacement of the UL2 and a localized crossbite

Initially, Headgear was used but compliance was poor. It was therefore decided to remove both maxillary second premolars to recreate space for maxillary arch alignment.

Therefore, Self-ligating brackets (SLBs) were used in this case after extractions. What are SLBs and what are the advantages of these systems? Why has glass ionomer cement been placed on the maxillary first molars? What is the final buccal segment relationship

Ortho Case 2.18

13 year old patient presents complaining of the appearance of his teeth, in terms of UR1.

The problem list:

• Discoloured, ankylosed UR1
• Mild skeletal class III pattern
• Increased vertical proportions
• Mild crowding in the upper and lower arches
• Evidence of dento-alveolar compensation in the lower arch, with a retroclined lower labial segment

What is the long-term prognosis for the UR1? How will this affect the management of this patient’s malocclusion? What changes in the patient’s malocclusion may occur with future growth? Whilst monitoring the patient’s developing malocclusion, how would you manage the ankylosed tooth?
