To implement an automated fluid magnetic abrasive (FMA) finishing process, an online monitoring scheme is proposed based on characterising acoustic emission (AE) signals in this paper. According to the material removal mechanisms during the FMA finishing process, the AE generation and characteristics are predicted analytically to be dominated by the interactions between the surface asperities a...

This study sought to assess the effect of different surface finishing and polishing protocols on the surface roughness and bacterial adhesion (S. sanguinis) to polymethyl methacrylates (PMMA). Fifty specimens were divided into 5 groups (n = 10) according to their fabrication method and surface finishing protocol: LP (3 : 1 ratio and laboratory polishing), NF (Nealon technique and finishing), NP...

The aim of this study is to examine the effect of different finishing and polishing systems on the surface roughness, microhardness and microleakage of a nano-hybrid composite. The effect of four different finishing and polishing systems (Mylar-strip, Diamond finishing bur, Sof-lex disc, PoGo) were evaluated on a nanohybrid composite (Ceram-X mono, Denstply). The surface roughness was measured ...

Aim: The study evaluated the efficiency of various finishing and polishing systems and the effect of finishing and polishing time by using various procedures on surface roughness and hardness of silorane based (FiltekP90) and methacrylate based (Z100) restorative materials. Method: The surface roughness and surface hardness were measured using a profilometer and Vickers hardness tester respecti...

AIM The aim of this study was to investigate the surface roughness of different types of flowable restorative resins and compare the effectiveness of diamond finishing burs followed by aluminum oxide discs with aluminum oxide discs alone in producing smooth surfaces. METHODS AND MATERIALS Twenty-four specimens (10 mm X 2 mm) for each flowable resin (flowable microhybrid composite, flowable li...
