Bilateral palatal canine retention and two agenesic teeth
Canine retention occurs when the teeth stay within the bone and do not erupt. It is a relatively common problem that mainly affects upper canines, but it can affect other teeth as well.
They are complex and long treatments in general. Due to their genetic character, they are usually associated with small teeth, delayed tooth eruption, lack of other teeth (agenesis) and transpositions (teeth with their positions exchanged).
This patient had her two upper canines retained in the upper jaw, between the roots of the incisors, as shown by the initial X-ray. The upper arch photographs illustrate how the canines are gradually getting closer to their site.
In the end, everything seems to have been very easy, but it is not! The lower second primary molars are still in the mouth because she also has two agenesis (her two lower second premolars are missing).
