background: sterilization techniques could affect the characteristics of orthodontic wires. the aim of the present study was to evaluate the effect of steam and dry heat sterilization techniques on load-defl ection behavior of fi ve types of β-titanium alloy wires. materials and methods: the samples consisted of 30 straight lengths of fi ve types of β-titanium alloy wires: titanium molybdenum a...
OBJECTIVE To compare the frictional resistance between self-ligating and conventional brackets tied to different types of wire. MATERIAL AND METHODS Abzil Kirium Capelozza (Pattern I) and Easy Clip (Roth prescription) incisor brackets were used. An elastomeric ligature or a 0.10-in ligating wire was used to ligate the wire to the Abzil bracket. Three types of orthodontic archwire alloys were ...
Abstract. The growing market for fiber-reinforced thermoplastics (FRTP) requires new flexible production processes prototype and small series production, as conventional forming techniques involving molds are not cost efficient in these cases. Inspired by incremental sheet metal (ISF), an alternative manufacturing the of FRTP with just two robot guided standard tools is outlined. To maintain a ...
Determining a feasible bending sequence, i.e., ensuring absence of wire self-collisions and wire-machine collisions, or even an optimal minimising time energy required to perform it, is difficult time-consuming task for complex workpieces, expert operators. Introducting algorithms the computation wire-bending sequences thus crucial increase productivity production flexibility, decrease costs. T...
BACKGROUND A number of studies have shown that non-critical medical devices can be contaminated with pathogens, including those resistant to antibiotics and thus become a potential vector for transmission. Electrocardiography (ECG) lead wire are non-critical medical device which are always attached on patient skin during their stay in intensive care unit (ICU). In view of the patient's critical...
Endoscopic placement of plastic stents to treat stricture of the main pancreatic duct (MPD) due to chronic pancreatitis has been widely accepted [1]. In spite of the improvement of endoscopic skills and devices, proximal migration is one of the most troubling problems. Here we describe a new technique for removing a pancreatic plastic stent (PPS) from the MPD. We present a case of a 47-year-old...
