OBJECTIVES The aim of this study was to investigate the effect of delayed finishing/polishing on the surface roughness, hardness and gloss of tooth-coloured restorative materials. METHODS Four different tooth-coloured restoratives: a flowable resin composite- Tetric Flow, a hybrid resin composite- Venus, a nanohybrid resin composite- Grandio, and a polyacid modified resin composite- Dyract Ex...

This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...

It has been widely recognized for many years that proper finishing is of critical importance in achieving an excellent occlusal result after orthodontic appliance removal. This clinical presentation deals with defining finishing goals and achieving them with the appropriate treatment mechanics for optimal esthetics, function and stability. It highlights certain occlusal static and dynamic perio...

The already initiated studies are based on size and forms of abrasive grains, but few studies have addressed the influence on the concentration of abrasive grains. This research has been done to remove some of the mysteries associated in the media "abrasives" or "chips" used in vibratory and barrel finishing, this process included within the functions and characte...

Currently, the genome sequencing community is producing shotgun sequence data at a very high rate, but genome finishing is not keeping pace, even with the help from several automated finishing tools, such as autoFinish. One reason for the slow progress in finishing is that repetitive regions longer than the length of a sequencing read cannot be assembled correctly with many current assembly too...

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...

274 Optimization of process parameter for surface finishing in abrasive flow finishing process Ravi Gupta (M.E) Asst. Prof.(Lovely Professional University) [email protected] , Abstract-Abrasive flow finishing is a non-conventional finishing process that is used for finishing of work piece which are difficult to finish by conventional method i.e. by honing, lapping and other machining operati...

Fused Deposition Modeling (FDM) parts are typically subject to process-related rough or wavy surfaces, with stair-stepping effects whenever the parts produced have sloped or rounded part geometries; however, the level of optical quality frequently required demands that parts feature a smooth surface. In this paper, the results of a high-energy finishing process, which uses a disc finishing unit...

The objective of this study was to determine if dietary cation-anion balance (DCAB) affects the concentration of S that can be tolerated by growing and finishing cattle without adversely affecting performance. Angus cross and Bradford steers (n=114; average initial BW=252.8 kg) were blocked by BW and breed, and randomly assigned within a block to treatment. The design was a 3 × 2 factorial arra...

Three hundred six crossbred steers (703 ± 1 lb) were used to determine effects of adapting steers to a finishing diet using RAMP for 14 to 30 d on steer performance and carcass characteristics. RAMP treatments were compared to a traditional step-up procedure (CON) utilizing an initial concentration (DM-basis) of 32.5% steam-flaked corn (SFC), 45% alfalfa hay (ALF), 20% Sweet Bran, and 2.5% supp...
