Inferior Incisor in good posição
1 - NB = 5 mm.
Discreet protrusion of Superior
Presence of third molars.
Severe dental apinhamento.
An evident case for extrations
of 4 first bicuspid ( 14, 24, 24 and 44 ).
3 years, are expanded the arcades superior and inferior, so much
in the traverse and the postero-anterior direction. The result is
demonstrated in procced imagens:
|Current pictures - July 1999 - after 3 years of expansion. Lower
Caninos (33 and 43) and Right Central
Incisor (41 ) with several retraction.
If now the teeth are already out of its bases bony, so much no traverse sense how much protusion
Incisor, as it would be if it continued with the same mechanics?
|Current Cefalograma - July 1999 -
The proctution of the Lowe Incisor is 4 mm.
1 - NB = 5 mm. Iniciais
1 - NB = 9 mm. Atual
|When beginning the treatment the Lower Incisor they were normal,
just 1 mm. the plus, do
that the 4 mm. suggested by Steiner.
Three years of expansion and the incisive inferior are with 9 mm. they were protruídos 4 mm.
It was transformed in a protrusion incisal that impedes the good he closes normal lips.
1 - NB = 5 mm. Initial
1 - NB = 9 mm. Atual
|The superior arch was expanded + 7 mm The arcade inferior was expanded + 8 mm|
|Presence of third molars.
If it went successe to correct the growding, is
necessary extracion of the third molars. Therefore
the case would be of extraction.
Thus, with it is improper expansion, such harmful
for the patient, equal would fall in a case of
A youth's girls, with 17 years.
|Two and a half years ( 2.5 ) of expansion.
The tood they were removed of its bone bases.
The rootses of the Canines and Loweer Incisors
they are without alveolar bone covering, they
can be seen by transparency.
The retraction in the Superior Canine it is a
All this damage to say that the case
it is done without extractions, and now é
necessary to extract the four third molars....
