Abstract

U ovom radu analiziran je utjecaj parametara postupka elektrolitičkog-plazma poliranja na stanje površine ispitnih uzorka izrađenih od titanijeve legure, koja se koristi za proizvodnju dentalnih protetskih nadomjestaka.
U teorijskom dijelu rada, nakon uvoda, obuhvaćen je povijesni pregled dentalnih protetskih nadomjestaka. Također, detaljno su opisane različite vrste dentalnih protetskih nadomjestaka, istaknuti su zahtjevi vezani uz njihova svojstva, pružen je pregled postupaka obrade njihovih površina te su navedene vrste metalnih materijala koji se koriste u izradi dentalne protetike.
U eksperimentalnom dijelu rada, najprije je opisan proces izrade ispitnih uzoraka koji su potom podvrgnuti postupku elektrolitičkog-plazma poliranja uz primjenu različitih parametara postupka. Nakon provedbe postupka, na ispitnim uzorcima izmjerene su vrijednosti parametra hrapavosti površine Ra, a površine uzoraka analizirane su pomoću digitalnog mikroskopa.

Abstract (english)

This paper examines the influence of various parameters of plasma electrolytic polishing on the
surface properties of titanium alloy used in manufacure of dental prostheses.
In the theoretical part of the paper, a historical overview of dental prostheses is given after the
introduction. Also, described in detail are different types of dental prostheses, their property
requirements, as well as the types of surface treatment and metal materials used in their
manufacture.
In the experimental part of the paper, the process of manufacturing test specimens is first
described. The test specimens were then subjected to plasma electrolytic polishing using
various parameters of the process. Lastly, the values of the surface roughness parameter Ra were
measured on the test specimens and their surfaces were analysed using a digital microscope.
