Not a single person in the world has perfect teeth that do not require at least periodic check-ups and treatment by dentists. Due to the fact that modern technologies are developing at a rapid pace, dental treatment is quick and painless.
In order for the doctor to perform the necessary manipulations with maximum efficiency when treating the oral cavity, dental clinics try not to save on special equipment. One of the elements of such equipment is dental handpieces, which are designed to transfer rotational motion from the drill installation directly to the element itself, which acts on the tooth surface.
In this article, we will consider the main types, types, characteristics of tips, their purpose, as well as selection criteria.
Content
All nozzles are divided into 4 large groups - turbine, angular, straight, special.
The principle of operation of the turbine nozzle is based on the use of a compressed air stream that drives a rotating element. This system is the “weakest point” in the entire system, as it is subjected to increased loads. In order for the device not to fail, it must be lubricated at least twice a day, and also after each disinfection. Such devices also require special storage conditions - in accordance with the manufacturer's recommendations, they should be installed in special vertical holders with their heads up or down. Special packages are provided for the storage of sterile dental equipment. The best manufacturers offer such bags complete with a tip. The main advantage of such nozzles is the high speed of rotation - from 300,000 to 500,000 rpm. Cooling in such devices is mainly air-water. Personnel must wear a protective mask, all work is carried out using a saliva ejector and dust ejector to prevent dust and water particles from entering the patient's respiratory tract.
Corner nozzles (also called Right Angle) are driven by an electric or pneumatic motor. In appearance, they resemble the previous model, but the speed of rotation of the motor is much lower - from 20,000 to 70,000 rpm. These devices are used for manipulations such as polishing fillings, preparing cavities for inlays, opening root canals, etc. In such manipulations, high power is important, which is achieved at low speeds.The value of the power of the angular model exceeds that of the turbine one by almost one and a half times.
The principle of operation and functionality of handpieces (Handpiece) is similar to the angular ones, their feature lies in the design, due to which the impact on the rotating element is increased. Such devices are used in cases where the power of other nozzles is not enough - opening the root canals on the front teeth, processing dentures, etc.
In cases where the use of the considered nozzles is impractical due to inconvenience, special devices are used, among which are endodontic, surgical, and also for removing tartar.
Most popular models of endodontic instruments operate from their own battery, and can perform translational movements (used to expand root canals, contribute to the formation of a cavity convenient for filling), rotate at low speeds (used for filling using gutta-percha pins), perform reciprocal rotational movements (greatly facilitate the work of dentists to expand the canals), to carry out a vibrational effect (used to prepare wide root canals).
The scaling tips are designed to deliver high vibrations to the surface to be treated. When processing the surface, water is constantly supplied to it to prevent excessive heating.
There are so-called sonic tips, which are activated by rotating a special sleeve with compressed air, as a result of which the device is given a circular motion.
Sandblasting nozzles are mainly used for grinding the tooth surface. The removal of the dentin layer is carried out by feeding particles of aluminum oxide and other compounds under high air pressure. Such devices are effective when working with hard-to-reach cavities. The advantage of the technique is the absence of vibration and discomfort for the patient.
Surgical tips are used in various operations, they must withstand sterilization at elevated temperatures of about 140 ° C.
This nozzle belongs to the category of turbine with a friction clamp. It is used for therapeutic and orthopedic work. The product is made of brass and plated with chrome. The tool is suitable for any burs with a shank attachment diameter of 1.6 mm. There is a built-in LED lamp to illuminate the work surface for a complete view.
In order to make it easy to clean, special grooves are provided on the body. They also contribute to the convenient location of the product in the hand. German-made components used in the tool (bearings, rotor group) ensure long and reliable operation.
The built-in double spray cooling system prevents overheating and failure of the device. There is also a pressure control valve that reduces pressure to reduce excessive wear on the rotor during rotational movements. The head of the product is completely metal, thanks to which the aerodynamic flows are optimally distributed.
3 types of nozzles are made, which differ from each other by the type of attachment to the drill sleeve: M4, B2, R.The manufacturer guarantees trouble-free operation of the product for six months, and in case of failure later, it is possible to make repairs, with the replacement of the rotor group, ball bearings, lighting lamps. Since this tip is Russian-made, there are no problems with spare parts. The product can be sterilized at temperatures up to 135 °C. The scope of delivery also includes instructions that indicate how to use the device and what to pay attention to when using and storing the tool.

The Japanese company NSK Nakanishi is well known in the dental equipment market. The Pana series includes turbine handpieces with ceramic bearings. The Max modification is a modified version, in which the emphasis is on smoothness and reliability.
Unlike similar models, Pana Max has a thinner handle, which not only fits comfortably in the hand, but also makes it possible to carry out complex manipulations in hard-to-reach places, while the doctor gets a complete overview. Since the bearings are built directly into the shaft in this model, this helps to reduce vibration, resulting in less stress on the doctor's hand.
Branded push-button clip securely fixes the device and does not allow shifting or slipping from the sleeve. A special head cleaning system prevents the ingress of biological fluids, thereby protecting the bur from damage. The manufacturer allows the sterilization of the product in an autoclave at a temperature of 135 °C. For additional sterilization, a thermodisinfector can be used. There is a safety valve that does not allow excessive rotation speed, which can lead to damage to the device.

This device of Chinese origin is in great demand in dental offices, especially private ones. This is due to the fact that many managers, wondering which device is better to buy, are guided primarily by price, and not by quality.
The nozzle is used for sandblasting the surface of the teeth to remove plaque, tartar and other contaminants. The principle of operation is to supply a mixture of air, water and a special powder under pressure to the treated surface. As a result of mixing the composition, a spray is formed that removes even old contaminants, while the patient does not experience discomfort.
The nozzle is removable and can be thermally disinfected. It can rotate around its axis, thereby allowing it to be directed to the required place without any effort. For the powder, a special container with a screw cap is provided. The package also includes a spare cover, a set of gaskets, two cleaning needles (large and small). Also, the device is equipped with a filter that prevents the powder from returning to the drill sleeve.

When buying a drill handpiece, it is important to understand what it is and how it works. Since such devices outwardly practically do not differ from each other, you can purchase a device that will not only perform the functions assigned to it poorly, but will also quickly become unusable.
First of all, you need to pay attention to the material of manufacture of the apparatus, the presence and quality of bearings, and the cooling system. Lighting is desirable but not required. It would be useful to check the availability and duration of the warranty. The higher it is, the better the device in front of you.
We hope that our review will help you make the right choice and purchase a device that will work for a long time and with high quality, while not causing discomfort to either the patient or the attending physician.
