High Speed Rotary Polishing Micromotor Kit K.1070

Use Product Options Menu to Select Collet Size: 2.35mm (3/32") (K.1070) or 1/8" (K.107018).

For high speed micro motor applications up to 38,000 rpm including light deburring of cast pieces, bright cutting in jewelry making and fine detailing in wood. Kit includes control box, handpiece with 2.35mm (3/32") or 1/8" collet (depending on choice of collet installed), variable speed foot control, handpiece cradle, spare pair of motor brushes, spare fuse and collet changing wrenches. The back of the control box has a convenient Voltage Selector switch for operating with either 115 or 230 Volt operation. This Kit is already set for 110-115 Volt use. The control converts AC current to DC current required for the handpiece. Compared to flexible shaft machines, micromotors have less torque, however, their higher speed results in a comparable rate of material removal with a lighter touch. The simple cord connection between the handpiece motor and control box is another key advantage. Unlike the "drag" and general restriction in movement that you have with a shaft and sheath, micromotors offer much greater freedom of movement.
Kits K.1070 and K.107018 include:

HP4-917 Control Box
H.MH-170 Handpiece with 2.35mm (3/32") Collet installed OR  H.MH-17018 Handpiece with 1/8" Collet installed
HP4-960 Variable Speed Foot Control
HP4-933 micromotor handpiece Cradle
Spare pair of motor brushes, spare fuse, collet changing wrenches.
HP4-917 Control Box is compact with switches on the front for On/Off Power, Forward or Reverse Rotation, and Manual or Foot Speed Control. Speed can be adjusted from low to full speed using the dial on the box or with the foot pedal. An Overload Protector Light is also featured that turns red and sounds a beeping alarm when the motor stalls. This is the same control unit that comes in Micromotor Kits K.1020, K.1080 and K.1090.

H.MH-170 or H.MH-17018 High Speed Rotary Handpiece has a slender, contoured grip for precise and very high speed work and quick release rotary type chuck.

Is The Curing Light Dangerous Or Harmful To Look At?

The dental curing light is a very strong blue light.  It it not a laser or a UV light so it will not cause any damage to your teeth or gums.  The only danger is if you look directly at the light for too long.  Similar to how your eyes will hurt if you look at the sun for too long.  Dentists and assistants are advised not to look at the light for long periods of time.

There are two types of curing lights used by dentists.  There is a halogen curing light and an LED curing light.  Most modern curing lights are LED as they do not overheat like the halogen curing lights do.  The only danger with the halogen light is that the heat it produces could potentially hurt the pulp of the tooth or the soft tissues in the mouth.  Although this is possible, it is very unlikely.  The majority of dentists use LED curing lights these days.

What Does The Orange Shield Do?
The orange shield is a filter so that your dentist and assistant can still look in your mouth without the strong blue light hurting their eyes.  The light is okay to look at for a few seconds but it’s not nice for dental staff to look at for too long.

What Is The Blue Curing Light Dentists Use And Is It Dangerous?
Have you noticed the glow of a blue light during your dental visits?  People often wonder what this light is for used for and whether it’s dangerous or not.  The blue light is called a curing light and it is used for setting white fillings.

What Does The Blue Light Do?The blue light sets fissure sealants, fillings and cement in a matter of seconds.  When fillings are placed in the tooth they are very soft so they can be moulded to the correct shape by the dentist.  When the dentist is happy with the shape of the filling they will set it with this light.  The blue light makes the filling go rock hard and strong enough to chew on.  The blue light is also used when having braces fitted to set the cement which holds the brackets on your teeth.

10 Interesting Things About the Dentist’s Hanpieces

1.There are two main types of dental drills: the high speed handpiece and the slow-speed.  The high-speed drill rotates around 250,000 RPM.  That means it spins around more than 4,000 times each second!

Even the relatively slow dental drill rotates at about 8,000 RPM.  By comparison, this DeWalt Drill is three times slower with a top speed of 2,500 RPM.

2 .After using the dental drill on your tooth for 30 seconds, your dentist is subjected to as much bacteria as they would be had you sneezed right in their face (Source).  That’s one of the reasons most dentists wear face masks.

3 .The high-speed dental drill shoots out water as it spins, as you can see in the photo above.  If it didn’t, the friction would cause your tooth to get so hot during a filling that it could possibly damage the nerve inside your tooth.

4.Many dentists now refer to the dental drill as a low speed handpiece to make it seem more friendly and enticing.

5 .The dental drill has to withstand the rigors of sterilization after every use, which means it gets heated to 250° Fahrenheit with pressurized steam for at least 15 minutes.

6 .The very first dental drill appears to have been a bow drill used by an ancient civilization about 9,000 years ago.

7 .The drill bits that dentists use are made of tungsten-carbide.  Some have blades to cut teeth, like in the photo below, and others are coated with diamonds to give a sandpaper-like smoothing effect (see photo below).

8 .As recently as the early 20th century, many dentists used drills that were powered by a pedal that the dentist would pump with his foot.

9 .The distinct shrill sound that the high-speed dental drill makes can be a major factor in people’s fear of the dentist.  Even for those who don’t have dental fear, the dental drill’s noise can be very unpleasant.

10 .Dental drills can be expensive, with many costing over $1,000.  That’s a lot more expensive than your average home-improvement drill.

Generation of Changes of Dental Curing Light

Light-curing resin composites were introduced to restorative dentistry in 1969. The earliest light-cured materials were photopolymerized with ultraviolet light-polymerizing devices. This use of light curing ushered in an era of command set. When the light irradiated the restorative material, it initiated the setting-photopolymerization reaction of composite resins. The use of light curing paralleled the introduction of adhesive bonding of composites to enamel. These early curing lights had limited depth of cure due to the shorter wavelengths (10 nm to 380 nm) of UV radiation energy. In the mid-to-late 1970s, UV light-curing devices were phased out and replaced with visible light-curing devices using quartz-halogen bulbs (QTH) to light cure restorative materials that used photosensitive chemistries in the 460 nm to 480 nm wavelength, typically camphorquinone (CQ) for polymerization of composites.5 The longer wavelengths of this visible light spectrum allowed for a more penetrating curing light and light energy. This increased energy of photopolymerization introduced an era of improved physical properties with resin-based composites that were set by exposure to relatively safe, high-intensity light sources.

In the 1990s, there were significant improvements in best dental curing light devices. QTH devices had improvements that increased the energy to at least 6,000 mW/cm2, and in some cases using specialized turbo tips, more than 1,300 mW/cm2.2,6 At the same time, high-intensity light sources (a fluorescent bulb containing plasma) for resin-based composite curing and plasma-arc curing (PAC) with an irradiance range of 400 nm to 500 nm were introduced.6 A comparison of QTH- and PAC-cured composite resins demonstrated variation based on the composites and individual lights for different physical properties, but no one light type performed better than another.

A significant change in how resin-based composites were light cured occurred in the late 1990s, with the introduction of light-emitting diodes (LED) that provided light in the blue-visible spectrum with a range of 450 nm to 490 nm.8 Currently, the latest generation of LED curing devices provide consistent energy outputs of greater than 1,000 mW/cm2.2,9,10 The benefits of the latest generation of LED curing lights can include: higher, consistent light-energy output through emitter life; lightweight cordless features with rechargeable batteries; heat sink or quieter cooling fan; broader light spectrum with multiple LEDs for photopolymerization of resin-based composites with both CQ and other photoinitiators; and more useful light transmitted in ranges because of wavelength-specific emitters.

What are the factors that influence dental whitening process?

A primary reason results vary significantly is because many factors influence the whitening process. Some of these factors are controllable; some are not. And they may vary from system to system and person to person. Therefore, it is difficult to make claims that will satisfy the conditions of all those wanting a whiter smile. Primary factors include:
Color to start with – it is documented that those with more of a yellowish hue have greater response to whitening than those who have more gray or brown. Intrinsic gray discoloration is commonly seen in exposure to different types of medications. The most widely known is the antibiotic, tetracycline. Brown is often seen with excessive intake of fluoride, referred to as fluorosis. Fluorosis may also create a mottling or blotchy look to the enamel and make it equally difficult to achieve optimum results.
Unique and inherent whitening potential – it is believed that we each have a level at which our teeth cannot whiten any more.
Clean teeth – it is advised to have your teeth professionally cleaned to remove all deposits, as well as surface stain that may interfere with the whitening agent being in direct contact with the tooth.
Percentage of whitening agent – meaning the higher the concentration, the faster the results. However, the higher concentration can also result in a greater risk of sensitivity. Therefore, the percentage of whitening agent should be determined based on: how sensitive your teeth are to begin with; if you have any root surfaces exposed; the delivery system you choose and over what period you want results.  In-store or over-the-counter systems have a much lower whitening agent percentage, so it takes a little longer and may require more frequent touch-up. In-office systems provide a higher percentage, the alternative of using carbamide peroxide (teeth whitening machine for sale) and a more controlled application.
Duration of time – the whitening agent is in direct contact with the tooth surface. This is delivery-system sensitive as well. And it is related to the ratio agent. Each system requires a different timeline and should be followed accordingly. The key is to maintain direct contact with the entire tooth to provide even and precise whitening results.
Compliance – is easy when you choose a system based on your needs and concerns; when you use the system as directed and when you minimize risks. It is recommended to use an agent within neutral pH range. This is safer for the enamel and reduces sensitivity. Additionally, pay attention to all the factors that influence whitening and consult a dental professional with any concerns.
Oral habits – can play a major role in the whitening process. Before any application, it is a good idea to thoroughly brush and floss plaque, stain and food debris from the surfaces of the teeth. Maintaining good oral hygiene will keep your smile looking brighter longer.
Avoid – foods and drinks dark in color or that are acidic (tea, coffee, sodas, wine, grape juice, chocolate, orange juice), smoking and chewing tobacco. Beware of oral home care products that contain alcohol and dyes/colors or may be high in abrasion or acidity.
