Dental (dental) x-rays: overview of devices


Dental x-ray machine in modern conditions is a necessary device for successful diagnosis of many pathologies of zubochelyustny system. Without an accurate investigation of the structural features of the teeth and surrounding tissues cannot be fully therapeutic, orthopedic and surgical treatment. Dental x-ray is one of the inexpensive and fastest ways to obtain the most accurate information about the state of the maxillofacial region.

Types of dental x-ray machines

When choosing x-ray equipment for dental clinics many factors – performance, informational content, price, type logger image and many more.

Ray is a special sensor capable of converting x-rays passed through the human body in a digital image. For the work of the radiovisiograph is necessary installed and working high-frequency x-ray machine and a computer.

The principle of operation of the radiovisiograph is virtually indistinguishable from that of a conventional dental x-ray apparatus. The difference lies in the fact that the analysis of the results and drafting of the image occurs not on x-ray film and sensor, then the data is transmitted to a personal computer.

Radio sighting devices differ among themselves in structure. There are wireless and wired devices. Have wireless x-ray data transfer to the PC via a special scanning device, and places the sensor after scanning the desired areas of the maxillofacial region. In wired radio sighting devices the information transfer is through the wire connecting the sensor and the computer.

What are the advantage of intraoral radiology over conventional dental x-rays? The main distinct advantage of x-ray is a low radiation load on the patient due to the high sensitivity of the sensor. According to SanPiN, radio sighting devices can be placed in rooms adjacent to living quarters without breaking the rules of radiation safety. During the examination the doctor, dressed in a special apron can be placed near the patient without the threat of their own health. In addition, there is no need to move in the x-ray room for routine scanning – ray can be placed in the office.

In the market of dental equipment is well proven radio sighting devices firms KaVo, Soredex, Planmeca, Vatech.

System Gendex GXS-700 from the German dental equipment manufacturer KaVo relates to a radio sighting devices of the eighth generation having a lot of advantages:

  • Obtaining high-quality images.
  • The presence of two sensors of different sizes, for children and adults.
  • The ability to directly connect via the USB port.

The ProSensor intraoral radiology S0 from the Finnish manufacturer Planmeca features a durable sensor cable, allows you to extend the lifetime of the device; the sensor is waterproof, whereby it can be completely immersed in disinfectant solution, moreover, included are sensors in three sizes. In that case, if the patient made a sudden movement during scanning, the supply of radiation is terminated immediately.

Apparatus for intraoral radiography

Dental x-rays performed on the apparatus for intraoral photography, which are also divided into several types:

  • The classic apparatus for radiography is fixed to the wall of the Cabinet or placed it on the rolling rack.
  • Portable devices – portable devices, in appearance resembling a camera.

The device for dental x-rays and vary the frequency of the x-ray tube – high-frequency units produce more high-quality images.

X-ray unit Planmeca Intra (Finland) holds all necessary for proper diagnostic functions. The latest technology of radiography and a convenient design make the wall unit Planmeca Intra efficient device for intraoral diagnostic pathology of the dentoalveolar system. There is the possibility of self-configure the desired parameters power voltage and exposure time. Image settings are adjusted automatically depending on the diagnostic purposes. The device can operate in conjunction with a digital sensor.

Intraoral x-ray machine FONA X70 FONA from Dentals.r.o. (Italy) is a device that allows you to classic dental x-ray, working in both digital and film mode. The main feature of the device is a high power that allows to obtain a clear contrast image. The device includes a stabilizer that protects against overheating and voltage drop.

The control panel of the device is simple to use, allows you to select the type of the tooth and body of the subject, and the system automatically adjusts the scanning parameters. The program has 6 tuned circuits, providing high quality images.


Set dental panoramic x-ray allows to obtain two-dimensional and three-dimensional images of the maxillofacial region, giving a complete picture of structural features of the teeth, jaws and sinuses. The basic units have a minimum set of functions and have the average cost. Such devices allow to conduct research in several projections, and are preferred for the arrangement of small dental clinics at the expense of simplicity and ease of use. Pantomography with advanced features are much more expensive, they are placed in large hospitals with large patient flow.

The choice of the x-ray machine

When choosing x-ray unit for the dental clinic it is advisable to pay attention to the compatibility of the device with digital sensors (radio sighting devices) – this will allow several times to improve the quality of diagnosis.

It is recommended to buy ray and x-ray machine from one manufacturer – such measures will allow to avoid problems of incompatibility of equipment.

Before buying plants you should carefully review the requirements of SanPiN the organization of dental practices – in some areas it is forbidden to place a full-fledged x-ray unit. It is important to pay attention to the stability of the power grid – most of the machines give a huge load on the network, so it is advisable to use stabilizers of great power.

The modern market of dental equipment offers a huge selection of various radiographic devices. Before choosing the right machine should be to determine which tasks should be carried by the device and understand the requirements of radiation safety.
