title: [Possibilities of a computer tomography and 3D-reconstruction in estimation of temporomandibulare joint in patients with the secondary lowered bite].
abstract: In considerable decrease of bite height the interposition of firm and soft tissues of temporomandibulare joint (TMJ) varied, its function was broken. By means of a computer tomography we estimated width of departments of the articulate crack. The increase in back articulate space was regarded at bite correction as optimum result of treatment. Measurements were made at use of multiplanar 2D-reconstruction in sagittal projections. At performance of volume (3D) reconstruction it was noticed that in patients with atypical change of interposition of TMJ elements prospective rotation of position of a head at performance of functional tests (research performance in position of the closed mouth and at bite restoration on silicone forms) was not caught. However, in these patients clinical improvement was noted in all cases. Use of 3D-reconstruction facilitate understanding of an arrangement of heads of lower jaw in cavities of joints, including with the use of functional tests. However, to estimate the minimum degrees of rotation of position of heads of articulate shoots was not obviously possible. Also measurements of width of an articulate crack weew not absolutely representative in comparison with interpretation of multiplanar 2D-reconstruction.
