Piezotome is a progressive equipment for surgery with ultrasound. The principle of its operation is based on local destructive effect on bone tissue ultrasound radiation.

Ultrasonic device structurally consists of a "scalpel" with nozzles and a regulating unit, which sets the necessary frequency of oscillations to achieve the desired effect. The frequency range of the equipment is wide - 10-29000 Hz, with an amplitude of vibrations in the range of 60-200 microns. The power and frequency are selected by the dentist depending on the surgical objectives. This contributes to effective work with bone tissues of different structure and density.

Work experience: 13 years

Specialization: maxillofacial surgeon-implantologist and candidate of medical sciences.

Restoration of dentition solves not only functional problems, replacing lost teeth with artificial ones. Prosthodontists attach equal importance to the aesthetic component of prosthetics. Functionality and aesthetics are combined by the use of artificial gum.

Most often such a design is used in the manufacture of removable prostheses. Crowns are fixed in the base, creating a complete imitation of the gum and teeth in it. The material for such products are polymers: acrylic, nylon, AcryFree. The latter two are hypoallergenic, but acrylic can cause an allergic reaction. The teeth on the artificial gum transfer part of the load to the base, but this distribution is uneven. Adequate distribution is possible only with prosthetics on implants.

Gum problems can be expressed in different ways during implantation:

Even quality oral care does not eliminate the possibility of trauma or other factor that may require tooth extraction. The need to pull it out with forceps or saw it into pieces with a milling machine for fragmentary removal causes unpleasant associations, becomes a reason to postpone going to the dentist.

The innovation of 2017-2018 was the use of ultrasound equipment in dentistry - piezotome, for tooth extraction. Previously, ultrasound was used for the removal of dental calculus, treatment of periodontal disease.

Piezotome includes a block-regulator, which sets the parametric parameters (frequency of oscillation, amplitude), and ultrasonic scalpel with interchangeable attachments. Depending on the quality, structure, density of bone tissue, the surgeon sets the frequency in the range of 10-290000 Hz, amplitude 60-200 microns.

Tooth extraction is a surgical procedure that cannot be performed without damaging tissue and blood vessels. This causes bleeding from the tooth cavity. The blood forms a clot that protects the wound from bacterial invasion. Usually, it stops discharging from the wound after a few minutes, but there are cases when bleeding continues for hours or even days.

In dentistry, there are general, local and mixed causes. Bleeding can occur due to a doctor's error, non-compliance with the recommendations of the patient or taking medications to treat common diseases.

Gingival fistula is a pathological condition, the result of purulent inflammation near the root of the tooth with perforation of the gum tissue. This is a channel in the thickness of the gum, through which pus comes out from the focus of inflammation.

Diagnose and treat the disease by dentists: therapist, surgeon, sometimes a surgeon of maxillofacial specialization.

Externally, the fistula is a convex formation with a noticeable spot of white color on it. This means that the pathological process is accompanied by the formation of pus in large quantities.

The fistula is of two types:

Symptoms of a dental fistula are…

Normally healthy teeth have a small mobility due to the elasticity of the ligamentous apparatus and the need to cushion the chewing load. Physiologic mobility is 0.06 - 0.15 mm, absolutely imperceptible to a person. Excessive mobility that is noticeable when pressing on the tooth is an anomaly that requires dental intervention. Even if the mobile tooth looks normal, does not hurt, loosening indicates a violation of the gingival connection, which is fraught with the loss of a dental unit.

Pathologic tooth mobility occurs with various dental problems or trauma. What to do if a tooth is wobbly? Go to the dentist. Timely diagnosis and treatment will preserve the integrity of the tooth row, restoring the functioning of the ligamentous apparatus. The method of treatment is selected according to the degree of severity of the defect, the area of location, the presence of concomitant factors. Specialists of the RUTT clinic in Moscow after a comprehensive diagnosis…

Transplanting teeth from your own dentition is a procedure that is used as an alternative to implants. Everyone has teeth that do not participate in the chewing process, do not affect the bite, and do not perform any important functions. These are the wisdom teeth. They are the ones that, more often than not, become donor teeth. But not always.

There are teeth that grow outside the arch, spoil the smile, provoke inflammation. You can get rid of the problem by orthodontic treatment: installing splints, plates, braces. There are cases when the only solution is extraction. Then the tooth has a chance to benefit its owner. It can be grafted to the place where the tooth was lost or is planned to be extracted.

Another source of donors for transplants is extra-complete teeth. Some people grow twin teeth. Such units are direct candidates for extr…

Necrosis of the jaw is a severe inflammatory disease in which the bones of the facial skeleton are exposed and die off.

The disease develops when several factors combine. With other identical conditions, patients fall into the risk group:

Extraction (extraction) of a tooth is a surgical intervention accompanied by damage to the peri-dental tissues (gum, bone cavity, mucosa). Pain after tooth extraction is a normal reaction of the body to surgical intervention. Depending on the complexity of the clinical situation, the volume of the operation, after the procedure, when the effect of anesthetic stops (after 3-4 hours), the patient begins to feel aching pain in the injured area.

Pain occurs due to traumatic swelling of tissues, compression of nerve endings. The more complex and voluminous was the operation, the more intense the pain in the gum after tooth extraction. Normally, the symptoms after the extraction of an incisor or molar are as follows:

Wisdom teeth (eights, third molars) are the last units on each side of the tooth row. They are the last to erupt when the dentoalveolar system is fully formed. And in most cases, their appearance causes a lot of problems. Since they often do not have enough space in the row, they grow incorrectly: at an angle, sideways, horizontally, interfere with neighboring units, traumatize the mucosa of the cheeks, tongue.

Whether it is necessary to remove wisdom teeth - depends on the clinical situation. The doctor will not remove the third molars "just in case". There must be medical indications for this. The anatomy of the eights is more complex, they are the largest units in the row with a developed root system. Although they belong to the chewing group of teeth, they do not take part in the process of chewing, this function of the units is weakened or absent. The primary function of the third molars is to keep the teeth in the row from moving apart.
