Five groups were formed (12 rats in each group). Rats of groups 1-4 underwent a 1.5 cm long skin incision on the lateral surface of the neck. The formed defect in rats of group 1 was sutured with an interrupted suture, in group 2 it was sutured with an intradermal suture, in group 3 it was closed with skin glue based on 2-octyl cyanoacrylate, in group 4 it was welded with an electrocoagulator PATONMED EKVZ-300 (Ukraine). Group 5 included intact rats that did not undergo any manipulations. On the 7th and 14th day, 6 animals were removed from the experiment in groups 1-4.

In cases of wound closure with 2-octyl cyanoacrylate-based skin glue or by welding with the PATONMED EKVZ-300 electrocoagulator, collagen fibers looked mostly thinned, chaotically arranged in a dense intertwining network. The density of collagen fibers in the regenerate and the surrounding dermis did not differ depending on the different methods of wound closure. The collagen content in the collagen fibers of the regenerate increased on day 14 compared to day 7 for all methods of experimental wound closure. In cases of wound closure using a nodal or intradermal suture, the collagen content was higher compared to cases when the wound was closed with 2-octyl cyanoacrylate-based skin glue or by welding with the PATONMED EKVZ-300 electrocoagulator. In the collagen fibers of the dermis surrounding the wound, the collagen content was higher in cases of wound closure with a nodal or intradermal suture.

This method is particularly advantageous for delicate procedures in oral and maxillofacial surgery, including bone graft harvesting, sinus lifts, and tooth extractions. Piezosurgery operates on the principle of piezoelectricity, discovered by Jacques and Pierre Curie in the 19th century, where a piezoelectric crystal converts oscillating electric fields into mechanical vibrations. Devices used in piezosurgery generate ultrasonic frequencies (25-30 kHz) that enable linear vibrations and controlled cutting, selective for mineralized tissues.The technology offers significant benefits over conventional surgical methods, including improved visibility, precise and smooth cuts, and a reduced risk of soft tissue damage. Clinical applications of piezosurgery demonstrate its effectiveness in preserving vital cells such as osteoblasts and osteocytes, promoting faster healing, and better osseointegration of implants. Specialized inserts and operating modes enhance its versatility for various surgical needs. Piezosurgery has shown to lower postoperative complications and enhance patient safety in complex procedures like sinus lifts and bone splitting.
