METHOD OF TREATING JAW CYST Russian patent published in 2025 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, specifically to surgical dentistry and maxillofacial surgery, and is intended for use in jaw cyst decompression. Cone-beam computed tomography of a jaw with a pathological growth is performed. Digital impression is created in STL format; DICOM files of the cone-beam computed tomography of the jaws and the STL file of the patient’s intraoral scanning are compared in 3Shape software. 3D modelling of the individual template is performed. Pattern is made by 3D printing of the biocompatible medical polymer. Decompression device is made of a fragment of the infusion system of diameter of 5 mm by applying a red-hot spatula to a surface of the fragment of the infusion system at a distance of not less than a distance from a cyst bottom to a mucosal surface, thereby forming an external "button" so that the "button" fits tightly to the mucosal surface when inserted. Surgical intervention involves mounting the manufactured template on the dentition; osteotomy is performed through the bushing with using bone trephine 5.0/6.0 or a drill from the set for directed dental implantation. Surgical template is removed, one of the ends of the decompression device at a distance from the upper edge of the "button" to the bottom of the cyst is cut at angle of 45°. A decompression device with its skewed end is inserted into the defect against the stop to the cyst bottom and fixed by means of four U-shaped sutures. First needle is pricked in at an indent of more than 5 mm from the wound edge into the oral mucosa surrounding the decompression device, in the direction from the outside to the inside of the decompression device, the second needle stick is from the inside of the decompression device to the outside; cyst cavity is washed; decompression device is left for at least 2 weeks.

EFFECT: method enables providing the cyst decompression surgery accuracy, placing the decompression apparatus into the area with the thinned cortical plate, reducing the intervention length, minimizing the bone loss, reducing the risk of complications.
