Treatment of class I malocclusion
Class I occlusion can be defined by Angles, classification as the
mesiobuccal cusp of the upper 1st permanent molar occlude with
the developmental groove of the lower 1st molar.
According to certain criteria, class I
occlusion can be subdivided into:
1))Normal class I occlusion: Meaning
the molar relation is class I and there
is no tilted and/or malposed tooth or
teeth. Also the antero-posterior
occlusal relationship is (normal) class
I and there is normal overbite and overjet. Moreover, there is normal
transverse as well as vertical relationship between the archs, adding to
that the lower incisor,s edges occlude at the (cingulum) middle third of
the palatal surface of the upper incisors and the upper canine located
between the lower canine and 1st permanent premolar.
2)) Class I malocclusion: here the molar relation, similar to the 1st type,
also is class I (the antero-posterior occlusal relationship is normal) but
there is a discrepancy either within the arches and/or in the transverse
or vertical relationship between the arches.
a. Crowding and irregularities of teeth.
b. Spacing of teeth.
c. Localized malposition.
d. Discrepancy in the transverse relation (crossbite).
e. Increase overbite and anterior openbite.
? Aims of class I malocclusion treatment:
o To improve esthetic of the patient.
o To improve function of the teeth and the jaw.
o To improve good oral hygiene and subsequently less carious
lesion.
