ABSTRACT
Maxillofacial anomalies occupy one of the first places among the diseases of the maxillofacial region and are
characterized by significant morphological, functional and aesthetic disorders already at the early stages of bite
formation. Most often there is a combination of sagittal and vertical anomalies of occlusion. Oral examination plays a
major role in the detection of dental pathology, diagnosis, choice of treatment method and is an important part of the
general examination of the div.

INTRODUCTION
Since 1915, many researchers have attempted to create
a volumetric model of a face with teeth standing in an
anatomically correct position. This was a complex and
labor-intensive process that proved to be unworkable.
In the 1980s, 3D imaging of the maxillofacial region
began to develop. This technology included laser and
computer topographic scanning, stereolithography,
moiré topography, stereophotogrammetry and other
methods. Improvement of diagnostic methods in
maxillofacial surgery requires introduction of more

informative and ergonomic methods into practice,
which became possible due to computer technologies.
The transition from two-dimensional analysis -
telerentgenogram of the head in lateral and direct
projections,
symmetroscopy,
symmetrography,
photosymmetroscopy and its modification of two-
dimensional digitizers - to three-dimensional analysis is
necessary, in which the most reliable assessment of the
parameters of the dentoalveolar system is possible.
Standard measurements with a ruler cannot give a
spatial representation of the treatment or diagnostic
situation. In recent years, the number of patients
requiring plastic surgeries to correct deformities of the
maxillofacial region has been increasing. Recently, the
requirements of patients to the quality of medical care
have increased and continue to increase worldwide.
The aim of this study is to investigate the role of
multispiral
computed
tomography
with
3D
reconstruction in the diagnosis of maxillofacial
deformities.
MATERIAL AND METHODS OF RESEARCH
A special place in the diagnosis of anomalies of the
dentoalveolar system is occupied by the creation of a
complex three-
dimensional model “head
- dental
rows”. However, it is necessary to point out the
important tasks of dentistry, for the solution of which
a complex model, including the surfaces of the face
and jaws, is necessary. The complex model is
understood as a triangulated description of the facial
and jaw surfaces with precise spatial positioning of
them relative to each other.

Thanks to the comprehensive application of X-ray MSCT, it is possible to create a three-dimensional spatial
representation of facial tissues, which is important for planning complex orthognathic surgeries. 3D MSCT produces
digital images, including color representation of the object, which facilitates interactive visualization.

Results of the study and their discussion
Construction of three-dimensional graphic models
was based on obtaining in minimal time intervals X-ray
computed tomograms, which allow to create texture
segmentation and three-dimensional reconstruction of
organs. This is diagnostically significant due to
visualization of the human div in different planes
with the possibility to examine internal surfaces of
both soft tissue contour and bone structures.
The construction of such a complex model will make it
possible to solve the problem of accurate
determination of parameters and individual features of
occlusion and to plan orthodontic and surgical
treatment. Currently, this task is solved using
radiographs, which does not provide the required
accuracy and involves harmful radiation exposure for
the patient.

CONCLUSION
Thus, the analysis of a number of parameters that are
very informative for performing cephalometric analysis
in assessing the state of the dentoalveolar system
emphasizes the importance of transition to three-
dimensional diagnosis.
Physiologic occlusion is not the only criterion of
harmonious development of the dentoalveolar system,
but is only a part of the triad: “joint
- muscles
–
occlusion”, the correct interaction of the components
of which is necessary for the normal functioning of the
orofacial complex.
The
proposed
method
of
three-dimensional
diagnostics of the occlusal plane position allows to
reveal its asymmetry, which is impossible in any two-
dimensional analysis due to the overlapping of the left
and right sides.
