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.
