The Features of Electric handpieces and Air-driven Handpieces

Electric handpieces are available that give dentists added benefits when compared to their traditional air-driven counterparts. One significant difference is having a specific RPM, with constant torque and less “bur chatter” (more concentric), so that when polishing or cutting through various types of tooth structure or restorative materials, the bur does not “bog down” or slow down when performing the clinical task. In many clinical situations, an electric dental handpiece can perform the same functions that both an air-driven high-speed and separate low-speed unit can.

Since most clinicians still prefer individual handpieces for high and low speeds so they can be more efficient chairside, this may not make a difference when choosing between the two systems; however, the higher initial investment for electric handpieces may be a consideration for some clinicians. Also, given the ability to “dial in” the desired RPM and use different contra-angles that have different gearing ratios, the electric handpiece can be custom-tailored to perform many other types of clinical procedures such as rotary endodontics, implant placement, and third molar removal (via tooth sectioning), for example. This clinical versatility is very desirable in today’s dental practices where multidisciplinary treatments are becoming increasingly common.

Control panels for electric handpieces are also becoming more automated, allowing the operator to use preset buttons to specifically dial in an RPM for a specific procedure. For example, most polishing procedures should be performed at lower RPM to minimize the generation of heat. Polishing of composite materials can be accomplished efficiently at speeds of 6,000 RPM to 8,000 RPM. Ceramic polishing is generally done in the range of 12,000 RPM to 15,000 RPM. Presets can be made at reduced RPM for caries removal, fine margin refinement on restorative preparations, endodontic cleansing and shaping, and implant drills and placement, to name a few applications. Some models also allow for torque control and have an automatic reversing feature for endodontics( Endodontic Motor ).

These features eliminate any unpredictability and guesswork compared to using a traditional low-speed unit with only an air-pedal foot control. Having the ability to reverse the rotation of the instrument in an electric handpiece is also a helpful feature when polishing restorations because of the importance of having the polishing instrument rotating from the restorative material toward the tooth to avoid damaging or “ditching” the margin.

A recently introduced feature in an air-driven handpiece combines some of the benefits of traditional air-driven and electric handpieces into one instrument. Two new technologies incorporated into this handpiece are speed sensing intelligence (SSI) and superior turbine suspension (STS). These features allow this handpiece to deliver the benefits of constant torque at high speeds when performing various dental procedures, specifically cutting enamel and dentin and removing or sectioning through different types of restorative materials, including metal and zirconium.

According to the manufacturer, some of the benefits of these technologies in an air-driven handpiece are: automatic optimization of power, that is, constant speed under load to avoid stalling; delivery of smooth, constant power and control for maximum cutting efficiency and faster removal of material; speed adjustment of the bur when it is not under load to minimize wear on the bearings; and allowing the handpiece to operate at 330,000 RPM under load without bur chatter or deflection.

Dental Compressor

How to Choose the Good Dental Compressor

Some units are portable, allowing practitioners to move them around as needed. Others are mounted in a practice. For hygiene reasons, the dental air compressor is typically attached to short tubing. Dentists may place a unit between two treatment rooms, for example, providing access from either side while leaving the tubes short to reduce the risk of breeding bacteria. The best option for a facility can depend on the number of patients it sees and the kinds of procedures it performs with the use of compressed air.

A small compressor has the advantage of being lightweight, quieter and cheaper. However, if asked to work beyond its capacity, it will overheat and cut out. It is often suggested that if the practice intends to perform restorative work it is best to have an oilless compressor, to prevent oil droplets in the airline contaminating the restorative material.

The temperature that surrounds an air compressor is integral to the quality of the machine’s performance. If the air that surrounds the compressor is hotter than normal due to rising outdoor temperatures, it can affect the performance of pneumatic tools and machines. Therefore, it’s crucial to ensure that the air compressor itself maintains consistent temperatures throughout the year, including those months where outdoor temperatures top 80 degrees.

In recent years, increased awareness over the detriments of air contamination has spurred the development of advanced filtering systems for compressed air. The trend has gained steam in tandem with the move towards conservation and energy efficiency, both of which have been aided by the widespread adoption of pneumatic tools and machinery.

In order to prevent an air compressor from getting hotter during summer, the coolers must be cleaned each year just as temperatures begin to rise. If the coolers are clogged, it could impede their ability to keep your compressed air system at desired levels. To prevent this from happening, perform the following actions several weeks in advance of each summer:

Inspect the coolers for traces of dirt, gunk or misty residue.
Clean away any dirt deposits present on the coolers.

If the air compressor gets overheated, the impact could be troublesome for the compressor itself, as well as for any attached pneumatic tools and machinery. If a compressor is used to power air blowers, for example, the quality of air that reaches the end point could be ill–suited to the task at hand when the system is overheated.

Both new and used dental air compressor options are available. Some manufacturers offer refurbished units which have been carefully serviced before sale. These units are similar to those that are new, but have a lower price because they’ve been gently used. It may also be possible to rent a unit, which can help defray the startup costs for a dental practice. The equipment needed to start offering services to patients can be substantial, making it expensive to start a new business.

The Use of Dental Air Polisher

Dental air polisher was developed in the early 1970’s as a technique for fast and efficient removal of extrinsic stains, plaque and other soft deposits from the teeth. It comprises a stream of pressurized air carrying specially graded particles of a mild soluble abrasive usually sodium bicarbonate, mixed with a stream of water.

Dental root form implants are manufactured from a highgrade titanium alloy, the surface of which consists of a micro layer of titanium oxide. The implant surface can also be treated by plasma spraying, acid etching, sandblasting or coated with HA. The removal of plaque and calculus deposits from these implant surfaces with Dental Instruments designed originally for cleaning natural tooth surfaces can result in major alterations to the delicate titanium oxide layer. Altering the surface topography by roughening the surface may enhance calculus and bacterial plaque accumulation.

Resulting scratches, cuts or gouges may also reduce the corrosion resistancy of titanium, and corrosion and mechanical debris can accumulate in the surrounding tissue. The aim of procedures for debriding dental implants should be to remove microbial and other soft deposits, without altering the implant surface, and thereby adversely affect biocompatibility. Increased surface roughness can lead to an increase in bacterial accumulation and resultant soft tissue inflammation. Because of the critical nature of the implant/soft tissue relationship, metal ultrasonic scaler tips, hand scalers or curettes should not be used as they have been shown to significantly alter the titanium surface.

If inflammation becomes established in the periimplant tissues, pocketing and bone loss can develop, which if left untreated, will result in the loss of the implant. Clinicians worldwide are advocating surgical regenerative procedures to restore or repair lost periimplant tissues.These techniques attempt to achieve the repair or regeneration of lost periimplant tissues,and rely on making the implant surface biocompatible with the healing tissues. This implies a detoxification of the previously infected implant surface.

Airpolishing with the H.S.T polishing system is an efficient and gentle means of debriding the implant surface to aid the removal of bacteria and bacterial toxins. The unique H.S.T. polishing system has been shown to result in no damage to the surface of titanium implants or transmucosol elements. An initial report has indicated that the HA coating can be removed with the H.S.T. polishing system.Removal of HA is sometimes indicated when the HA coating has been seriously compromised by the inflammatory process.

The Benefits of Digital Dental X-ray

Digital radiography is a type of X-ray imaging in which the images are transposed digitally onto computers or other devices rather than being developed onto film. Instead of using electromagnetic radiation and chemical processing to record an X-ray onto film, digital versions use digital sensors to record images onto an image capture device, which then creates a digital image file.

This file can then be used by medical staff members, and the file can be attached to a patient’s medical notes for future reference. It can be printed to paper or slide material so can be used the same as any standard X-ray, but without as much risk and usually at lower overall cost. The initial expenses with a digital system can be immense, but over time they usually pay for themselves. These sorts of imaging devices are most commonly seen in hospitals, specialist medical practices, and dental offices. Dental imaging requires a slightly different process but the technology and basic concept are the same.

Digital dental X-rays are used by your dentist to take images of your mouth, including tooth structure and your jaw bones. In order to take the digital images, your dentist – or a dental technician – will place a small sensor in your mouth, carefully positioned. This small sensor is connected to the processing computer by a very thin wire.

Your dentist or the dental tech inputs the command for the dental X-ray machine to send a X-ray through your teeth and into the sensor, effectively taking a photo of your tooth or teeth. The sensor captures the resulting image and sends it through the wire to the computer. Then your dentist will reposition the sensor and take additional digital X-rays until all of your teeth have been X-rayed.

With digital dental X-rays, your dentist or other dental professional is able to immediately see your teeth and jaw bones. This means that assessment and diagnosis is virtually instantaneous.

Digital Dental X-Rays – A Great Advance

Many dentists are now using digital dental X-rays, which have many benefits for you, as the patient. Among some of the many benefits for you, are:
1. A reduction in the amount of radiation you are exposed to during the X-ray process.
2. No need for dental film or processing chemicals in order for your dentist to be able to see the images.
3. An almost instantaneous ability to see the X-ray images, which means, if you’re in pain, you’re not waiting for the images to be processed and then viewed.
4. Your dentist is able to use color contrast in viewing and manipulating the X-ray image, in order to see all of the details in the image.

Intraoral Camera

The Uses of Dental Intraoral Camera

An intraoral camera is a tool your dentist uses to examine your mouth in as detailed a way as possible. The instrument, which may look like an oversized pen, has a camera that takes high-resolution footage or images of a patient’s mouth and shows the visuals real-time on a monitor—they’re like high-tech versions of the hand mirrors you see in your dentist’s practice.

One of the primary uses for an intraoral camera is in patient education. Dentists often find it helpful to be able to show patients exactly what is going on inside their mouths, and to highlight areas where medical attention may be needed. Patients are also less likely to defer or refuse procedures when they can clearly see the area at issue, as some people are suspicious of recommendations for dental procedures, due to concerns about cost, potential pain, or the fears about members of the dental profession.

Intraoral cameras have incredible technological features. With LED lighting, a head that rotates from 0 to 90 degrees, and powerful magnifying capabilities (some cameras can zoom in up to 100x), your dentist can examine your mouth in extreme detail. This means he or she can make diagnoses more accurately. The office can attach these photos to your health record to make tracking any changes simple. Additionally, because the visuals from the intraoral camera appear on the monitor as they’re taken, your dentist can discuss your oral health with you while you both see the images or footage.

Each feature that benefits the dentist also benefits the patient—maybe even more. Your dentist understands symptoms and conditions thoroughly, but it’s often difficult to explain precisely what is happening in a patient’s mouth using just a mouth mirror, which is small and hard to see, or an x-ray image, which takes time to print and doesn’t display images clearly.

The intra-oral camera makes record keeping a breeze. Because the camera can take pictures of decay or the beginnings of oral health conditions, images can be printed and placed into patient files. Previously, dentists merely attempted to write an explanation of problems found during exams. Now, dentists can accurately track the progress of treatments or problems for years following a visit. Furthermore, patients can receive printed pictures of the conditions the dentist finds, which may be beneficial for filing insurance claims.

When your dentist uses an intraoral camera during your examination, however, you’re seeing exactly what he or she sees right then. Dentists can display clear, colorful images, allowing them to point out any issues and discuss them with you immediately. You’ll certainly learn a lot about your mouth! And the more you see and understand, the more confident you can be when making treatment decisions.

The intraoral cameras designed for use in dental facilities come with disposable probes or probe covers to ensure that germs are not passed between patients, and they may come with a variety of options which enhance the functionality of the camera. Versions designed for home use are usually much more basic, but they can still be useful for people who want to see the inside of the mouth. Using a camera at home, someone can identify an issue which requires a dentist’s attention, keep an eye on a recovering surgical site, or teach children about the importance of oral hygiene.

What Do You Know about the Dental Equipment

An appointment with your dentist is not everyone’s favorite experience! But the reality is a lot less daunting when you consider that your dentist has a whole host of equipment to help him look after you and make your experience as pleasant as possible. What equipment does your dentist use to look after you?

Mouth Mirror
This is fairly self-explanatory and will almost certainly be used during your visit. Your dentist needs to get a good view of the inside of your mouth, including the backs of your teeth. The mirror allows them to see from all angles and help locate any potential problems much more easily.

Dental Syringe
The dental syringe is used to administer local anaesthetic to numb your teeth and gums so your dentist may perform procedures that might otherwise be painful for you. Syringes are also used to rinse or dry your mouth with water and air respectively, which is necessary for certain procedures. Syringes can hurt at first. The good news is, only for a second and the even better news is some of our practices now have pain free sedation, so you don’t even know your tooth is being numbed.

Dental Drill
The sound and the vibrations caused by the drill on your teeth may cause an unusual sensation but this is nothing to worry about. The drill is used to remove any decay attached to the tooth before filling in the cavity, although sometimes it is simply for polishing and smoothing the tooth once operating is complete.

Scaler

Dental hygienists generally use several tools during a dental cleaning, including a tooth polisher and a dental scaler. Tooth polishers buff teeth and eliminate tiny pieces of plaque. They generally have several different sized heads for cleaning hard to reach places. Scalers look a bit like metal hooks and are used to remove hard plaque, especially between teeth. Some people find the use of a scaler uncomfortable, depending on their sensitivity level, pain threshold, the length of time since the last cleaning, and the extent of plaque build-up.

Suction Device
During many procedures saliva and debris can build up in the mouth, which can make things difficult for your dentist. Small hoses are used to remove anything obstructing the mouth, making any job easier for everyone involved.

X-Ray
Sometimes a problem may not be immediately obvious so an x-ray which made by dental x-ray machine will need to be taken to show a more detailed view of the teeth and bones surrounding the affected area. Without an x-ray, problems such as decay can easily be overlooked.
