The aim of the research was a comparative clinical evaluation of the results of prosthetic treatment with chairside CAD/CAM crowns for molars made from hybrid ceramics VITA Enamic, blocks of feldspatic ceramics VITABlocs Mark II, blocks of leucite glass IPS Empress CAD. Material and methods. The study involved 30 patients aged from 19 to 60 years old with defects in hard tissues of molars. For clinical evaluation we used Β«Clinical criteria for evaluation of direct and indirect restorationsΒ» developed by FDI in 2007, which included the assessment of several aesthetic, functional and biological parameters. We also included 2 additional criteria indicators: the condition of the antagonist tooth and the hygienic condition of the prosthesis in comparison with the hygiene of natural teeth. All patients were randomized into 3 groups of 10 people. After the treatment the clinical quality assessment was carried out in the following time intervals: 30 minutes, 1, 6, 12, 18, 24 months after the fixation of the crown. Results. Clinical evaluation of the results of prosthetic treatment of 30 patients with chairside CAD/CAM crowns made from three different materials did not reveal any significant difference in the clinical criteria for evaluation of direct and indirect restorations within 24 months.Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ - ΡΡΠ°Π²Π½ΠΈΡΠ΅Π»ΡΠ½Π°Ρ ΠΊΠ»ΠΈΠ½ΠΈΡΠ΅ΡΠΊΠ°Ρ ΠΎΡΠ΅Π½ΠΊΠ° ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΠΎΠ² ΠΎΡΡΠΎΠΏΠ΅Π΄ΠΈΡΠ΅ΡΠΊΠΎΠ³ΠΎ Π»Π΅ΡΠ΅Π½ΠΈΡ Π±ΠΎΠ»ΡΠ½ΡΡ

Determining the spacecraft Foton M-4 attitude motion
Abstract:
The paper presents the results of reconstruction of the spacecraft Foton M-4 attitude motion in the single-axis solar orientation mode. The reconstruction is based on processing the measurements of two vectors: the spacecraft angular rate and the strength of the Earth magnetic field. The processing technique uses kinematical equations of the attitude motion of a rigid body. In its framework, the measurement data of both types, collected on a time interval, are processed jointly. The angular rate data are interpolated by piecewise linear functions and those functions are substituted in kinematical equations for components of the quaternion, which defines a transformation of the spacecraft coupled coordinate system to the inertial one. The equations obtained present the kinematical model of a spacecraft attitude motion. The solution of the equations, which approximates the real motion, is found by the least squares method from the condition of the best agreement between measurement and calculation data of the magnetic strength. The technique allows to reconstruct the attitude motion on time intervals more than 10 hours. The found reconstructions are used for calculation of residual accelerations onboard the spacecraft.Note:

Uncontrolled attitude motion of the prototype of the small spacecraft Aist
Abstract:
We present the results of reconstruction of the uncontrolled attitude motion of the prototype of the small spacecraft Aist during its flight at the beginning of 2014. The reconstruction was realized by processing onboard measurements of the Earth magnetic field. The measurement data were accumulated in time segments, which had length about 100 min. The measurement data on each such segment were processed sim-ultaneously by means of the least squares method and integration of the spacecraft attitude motion equations. The estimates of the mathematical model parameters and initial conditions of the attitude motion were obtained as a result of such processing. The results of processing some segments above made clear the attitude motion of the spacecraft.Note:

Determination of the spacecraft Aist attitude motion on measurements of the Earth magnetic field
Abstract:
We present the results of reconstruction of the uncontrolled attitude motion of the small spacecraft Aist during its flight in May 2013. The reconstruction was realized by processing onboard measurements of the Earth magnetic field strength. The measurement data were accumulated in time segments, which had length about 100 min. The measurement data on each such segment were processed simultaneously by means of the least squares method and integration of the spacecraft attitude motion equations. The estimates of the mathematical model parameters and initial conditions of the attitude motion were obtained as a result of such processing. The results of processing some segments above made clear the attitude motion of the spacecraft.Note:

Determining the small spacecraft Aist-2D attitude motion by measurements of the equipment KMU-1
Abstract:
The paper presents the results of reconstruction of the spacecraft Aist-2D attitude motion in summer 2016. The reconstruction is based on processing the measurements of two vectors: the spacecraft angular rate and the strength of the Earth magnetic field. The processing technique uses kinematical equations of the attitude motion of a rigid body. In its framework, the measurement data of both types, collected on a time interval, are processed jointly. The angular rate data are interpolated by piecewise linear functions and those functions are substituted in kinematical equations for components of the quaternion, which defines a transformation of the spacecraft coupled coordinate system to the inertial one. The equations obtained present the kinematical model of a spacecraft attitude motion. The solution of the equations, which approximates the real motion, is found by the least squares method from the condition of the best agreement between measured and calculated data of the magnetic strength. The technique allows reconstructing the attitude motion on time intervals more than 10 hours.Note:
