Results of videokinesiography in patients with a complicated course of acute cerebrovascular disorder by hemitype in the recovery period.

Restoration of the masticatory function is one of the key elements in the comprehensive rehabilitation for patients with acute cerebrovascular disorders (ACVD) of various degrees, as their consequences may include an impaired coordinated action of the neuromuscular system, and the dentoalveolar system in particular. In this context, the clinical presentation of stroke is characterized by motor and sensory deficiencies, which can eventually lead to dysfunction of the masticatory muscles, tongue, lips, soft palate and pharynx. The bilateral difference between such disorders, manifested by the discrepancy in the muscle mass and kinematic characteristics, is the peculiarity of this phenomenon. AIM: The aim of the research was to examine the features of articulatory activity in the mandible during chewing at the stages of orthopedic rehabilitation in patients with complicated acute cerebrovascular disorder with the neurological deficit by hemitype during the prosthetics with removable orthopedic appliances. MATERIALS AND METHODS: The study sample consisted of 45 subjects aged from 40 to 65 years, including 24 women (53%) and 21 men (47%). The study group included 25 patients with complicated ACVD with the neurological deficit by hemitype and 20 subjects for control who did not have general somatic disorders. All patients underwent prosthetics with partial removable laminar dentures with acrylic base and clasp fixation system. CONCLUSIONS: Non-parametric comparison in the groups showed that the most significant differences in videokinesiography between the representatives of the second group (ACVD) and the control group on the 30th day of observation were: a relatively smaller amplitude of vertical movements (p =.0001) and smaller amplitude of horizontal movements (p =.0000). Thus, the amplitude of vertical and horizontal movements of the mandible, in our opinion, can be considered as a reliable marker of the functional activity of the dentoalveolar system in patients with a complicated course.

Biological compatibility of metal structures of dentures made from multiple melted alloys.

The issue of reuse of metal alloys in dentistry raises debatable questions about their impact on the human body. AIM: The aim of the study was the evaluation of the biocompatibility of metal structures of dentures made from cobalt-chromium and nickelchromium alloys Remanium GM 700 and Remanium CSe after repeated vacuum remelting. MATERIALS AND METHODS: Clinical study and treatment with fixed prostheses based on Remanium GM 700 and Remanium CSe were performed among 120 patients aged 25-60 years. The biocompatibility of the above-mentioned denture designs with oral tissues was studied. RESULTS: Prostheses made from Remanium GM 700 and Remanium CSe alloys are biologically indifferent, which is confirmed by the indicators of alkaline and acid phosphatase activity within the physiological norm. Regardless of the number of remelts, these alloys do not cause dysbacteriosis. The obtained results do not depend on the terms of observation, which indicates the safe use of remolten alloys for dental prosthetics. CONCLUSIONS: The investigated alloys are biocompatible and can be used for the manufacture of solid structures of dentures.
