Introduction: A study of condyle position could be
of interest as many authors defend the hypothesis
that temporomandibular disorders are caused by
incorrect positioning of the condyle in its fossa during
Aim: Analyse the discrepancies in condyle position
in our sample and its possible relationship in maximum
intercuspation with different occlusal patterns,
sex and age.
Material and method: A study was made of a total of
124 patients who attended an orthodontic clinic for
treatment. The study included mounting of models
in a SAM II articulator and obtaining condyle records
using a Mandibular Position Indicator (MPI).
The statistical analysis consisted of descriptive statistics,
global crossed tabulations, conditioning to a
third category (X2 at 5%), and factorial correspondence
Results: Statistically significant associations were
found between the groups of cross bite with sagittal
condylar discrepancy on the left and the established
ranges of transversal condylar movement of the jaw.
Age and sex do not influence mandibular discrepancies
between centric relation and maximum intercuspation.
Conclusions: There is a discrepancy between the
central relationship and maximum intercuspation in
60% of our sample in the sagital plane and 75%
in the transverse plane. Occlusion, represented by
the groups of cross bite, is related to the condyle
position but not to age or sex.
