Improve Dental Mechanics

If the dentist uses dental BUR is because you need to do an implant, a Crown or a bridge. The development of an implant dental laboratory is very wasteful because it must fit perfectly to the patient. Phosphates are used as binding agents in the coating dental implants that acquire the required shape. Based on mold making by dentist denture is manufactured a dental model in plaster. The implant dental becomes first in wax and then elaborates with alloys such as gold, Platinum, or titanium. To manufacture the mold to make the alloy, the wax model is introduced into a mass composed of flour of quartz, cristobalite, magnesium oxide, Silicon sol and a binder based on phosphates. This binder reacts with magnesium oxide and hardening. Subsequently burns the mass at a temperature of 800 to 1000 centigrade.

The wax will melt thus creating a space in which the alloy is poured. Budeheim is one of the leading producers in the field of production of binders for masses of implants. FABUDENT, a fine powder of great quality, is a suitable Binder because it ensures rapid hardening and optimum stability of the shape without the need to expose it to additional heat. Finally, after all, the implant has to be adjusted as well to the patient as the original. This type of hand piece gives us the possibility of working at a right angle or angled so as shown in the image. The straight is very useful to perform work outside the oral cavity and the angled part allows us to work comfortably within the mouth, for example prophylaxis, polishing resins or amalgams and many more uses. Cave mention rotating instruments vary from the straight piece to conta-angled piece, the straight part uses some strawberries of greater length and are attached by friction; use in contra-angle are more short and at the end opposite to the active part take a Groove for the fixation system by click or bolt. With the advancement of electronics, appeared for several decades, small electric motors that rotate between 4,000 and 40,000 R.PM., and that adding them hand pieces and contra-angle handpieces multipliers or reducers, cover a range of 600 to 120,000 R.RM. In addition to the above there are contra-anguladas high-torque low-speed parts, these are used in implantology, where the bone without much friction must be drilled for not heated and not cause tissue necrosis, this also implies that they have additional cooling.

Video Camera

A video camera or camcorder is an electronic device that allows you to capture video and sound, and this is its main function. A video camera can record the signal or relay it to another device. Analog models recorded on video tape signal while digital models used as storage media digital media such as hard disk, memory cards, DVD, USB flash drives or magnetic tapes. Features see the main features of a video camera: image quality: optics, sensor, the form factor and the resolution is very important. For example, the standard TV format is 720 480 pixels 4: 3 HD Ready is 1280 720 pixels 16: 9 Full HD is 1920 1080 pixels 16: 9. Audio: should acquire a microphone better than the integrated microphone, as well as headphones to check the audio during recording.

Storage media: can be hard disk, memory card, memory, USB, DVD or tapes magnetic, not excluding each other. Connectivity: video camera must have TV and computer connections (HDMI, DVI, s-video, USB, Ethernet or Wi-Fi). Zoom: we must look at the optical zoom (produced by lenses) rather than in the digital zoom (generated via software). Controls: agrees that the camera has automatic controls (white balance, iris, focus) as well as manual control for advanced tasks. Size: dimensions and weight are important so that the video camera is comfortable to carry, as well as to secure it on a tripod. Types see different kinds of video camera: video tape recorder: analog video camera records the information in analog format on VHS tapes.

Digital video camera: record information in digital format in media such as hard disk, flash memory, memory cards, DVD or tape. According to the quality and performance, we can distinguish between domestic, semi-professional, professional camcorders and broadcast. Digital camera: until now, the devices designed to record video and capture images belonged to different segments, but it is now possible to have both functions in a single device, since the digital camera also records video, and can be used as a video camera. Compact Pocket video camera: have the size of a mobile phone, its main feature being the portability. They have quality HD, LCD screen, zoom, internal memory, card reader, USB connector and rechargeable battery. Integrated digital camera: devices with integrated, such as mobile phones, smartphones, PDAs or tablet PCs, photo camera can also capture video. At the beginning they were products of poor quality, but the heavy use that make users because of social networks has motivated a constant improvement of its performance. Webcam (web camera): send the signal in real-time to a computer or to a network (IP camera), having USB, Ethernet or Wi-Fi connectivity. Are used mainly for Telecommunications (chat, video-conferencing) or as security cameras.
