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…

Normalt sett har friska tänder en liten rörlighet på grund av ligamentapparatens elasticitet och behovet av att dämpa tuggbelastningen. Den fysiologiska rörligheten är 0,06 - 0,15 mm, vilket är helt omärkligt för en människa. Överdriven rörlighet som märks när man trycker på tanden är en anomali som kräver tandvård. Även om den rörliga tanden ser normal ut, inte gör ont, indikerar lossning en kränkning av tandköttsanslutningen, vilket är fyllt med förlust av en tandläkarenhet.

Patologisk tandrörlighet uppstår vid olika tandproblem eller trauman. Vad ska man göra om en tand är vinglig? Gå till tandläkaren. Tidig diagnos och behandling kommer att bevara tandradens integritet och återställa ligamentapparatens funktion. Behandlingsmetoden väljs beroende på graden av svårighetsgrad av defekten, platsens område, förekomsten av samtidiga faktorer. Specialister på RUTT-kliniken i Moskva efter en omfattande diagnos...

Transplantation av tänder från det egna bettet är ett förfarande som används som ett alternativ till implantat. Alla har tänder som inte deltar i tuggprocessen, som inte påverkar bettet och som inte har några viktiga funktioner. Det är dessa tänder som kallas visdomständer. Det är de som oftast blir donatortänder. Men inte alltid.

Det finns tänder som växer utanför bågen, förstör leendet, framkallar inflammation. Du kan bli av med problemet genom ortodontisk behandling: installera skenor, plattor, hängslen. Det finns fall där den enda lösningen är extraktion. Då har tanden en chans att gynna sin ägare. Den kan transplanteras till den plats där tanden förlorades eller planeras att dras ut.

En annan källa till donatorer för transplantationer är extra kompletta tänder. Vissa människor växer tvillingtänder. Sådana enheter är direkta kandidater för extr...

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.
