Abstract:
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.
