Abstract
The progress of modern medicine and the widespread introduction of new technologies in the treatment process requires health professionals to be informed about the opportunities offered by science to improve the results of procedures. For the first time Topler and Ortel, in the period 1866–1878, applied the stroboscopic effect to decompose the motion of fast-moving objects. It is known that the image we get in phonation is collective due to the peculiarities of the retina and vocal apparatus. The stroboscopic effect is based on the use of a high-frequency pulse lamp, which allows the illumination of the rapid movements of the vocal cords up to 5 times per second, by interrupting the light source. Thus, the actual phonatory oscillations of the vocal folds are replaced by delayed, observable visual perceptions, possessing properties of the real movements. When the patient is asked to sing a vocal, the energy of the sound is converted into light. The pulse lamp starts to light up and goes out with the frequency of oscillation of the vocal cords. The stroboscopic indicators that can be evaluated are: frequency of movement of the vocal cords, amplitude of oscillations, course of movement, etc. Laryngostroboscopy is used to assess vocal abilities for the diagnosis and differential diagnosis of functional dysphonia, and the diagnosis of processes associated with infiltration of a pathological process in the vocal muscle. In recent years, high-magnification laryngostroboscopes have been used. They allow better magnification and visibility, as well as video recording of the image. The prosthetic base is an important element in the construction of prosthetic structures. It not only provides stability to the prosthesis, but also affects the speech function. The relevance and importance of scientific issues for the study of voice capabilities in dental prosthetics are due to the fact that, in recent years, dental medicine has undergone a number of changes related to the evolution of technologies and methods for manufacturing dentures and materials that are used in the process. The aim is to synthesize a structure that, on the one hand, is strong enough not to fracture during mastication and thin enough not to affect the patient’s speech function. This means that dental professionals need to develop their skills to work with new and innovative technologies.
