Malocclusion of the teeth is when the upper and lower teeth are misaligned in the jaw. Once malocclusion is identified, it will be classified according to type and severity. For more information visit: https://www.jonathanalexanderabt.com/orthodontics-malocclusion-of-the-teeth

Malocclusion of the teeth is when the upper and
lower teeth are misaligned in the jaw. Once ma-
locclusion is identified, it will be classified accor-
ding to type and severity.
Angle’s classification method is based on a sys-
tem devised by Edward Angle, who is largely re-
garded as the father of modern orthodontics.

THE THREE CLASSIFICATIONS
IN THIS SYSTEM ARE:
Class 1: NEUTROCCLUSION - The posi-
tion of the maxillary first molar is correct
but there are issues with the spacing or
positioning of the other teeth, including
crowding, under or over eruption.
Class 2: DISTOCCLUSION - This type of
malocclusion refers to the misalignment
of the upper and lower first molars,
where the upper molar is anterior to the
lower. It typically results in an overbite.
Class 3: MESIOCCLUSION - In cases of
mesiocclusion, the upper and lower mo-
lars are also misaligned but the upper is
posterior to the lower molar, resulting in
an underbite.
EDWARD ANGLE
made orthodontics
recognised on a
scientific basis and has
been widely credited
with establishing
orthodontics as a
specialist branch of
dentistry.
