EXPERIMENTAL STUDY OF THE BIOMECHANICAL BEHAVIOR OF ARTIFICIAL TEETH WITH PROSTHETIC RECONSTRUCTIONS AND DIFFERENT SIMULATED IMPLANTATION DEGREES

Test tissue isolation, low sample sizes and the need to simulate physiological occlusal loads are factors that contribute to the complexity of the problem. [...]the versatility of clinical situations which include the use of various types of prosthetic restorations is a further challenge for any in vitro studies. To avoid lateral movements and composite stresses, the phantom was attached to the vibrating movable piece by means of a threaded screw on the vibrator plate [4,5]. Since the excitation of the system is cinematic, a KD-35 (MMF product) fixed with a magnetic support is used for measurements, amplifying the signal with a Bruel & Kjæ r 2836 load amplifier. [...]k, m, c constants obtained from the resonance diagrams for the three considered situations For higher amplitude signal, such as that plotted in Figure 7a, the frequency spectrum also contains, besides the main frequency, higher harmonics (Fig 7.b.) First of all, the model should be rigidly fixed to the mobile vibrator mass.
