METHOD FOR IMPLANT PROSTHETICS ON LOWER JAW WITH PROTECTION OF IMPLANTS AGAINST LOSS OF STABILIZATION Russian patent published in 2020 - IPC A61C8/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to dental implantology, and is applicable for direct implant prosthetics on a lower jaw. Cone-beam computed tomography is performed. Implantation prosthetics are planned in the program complex, the cortical bone is prepared to form a bone plateau under the arch-shaped prosthesis beam, three support implants are installed and their position is verified using a check beam, obtaining a verifying tire and an imprint of the prosthetic bed tissue simultaneously recording a central ratio of the jaws, assembling the prosthesis on the gypsum model in the dental laboratory, lining and equipping the prosthesis with teeth, fixing the prosthesis in the clinic on the day of the implantation operation by screwing the screws passing through the beam to previously introduced support implants. Implantation is performed with a force limitation of 35 N/cm, and if the implant is scrolled about its axis with such force, an individual device for stabilizing the dental implant is inserted, which is pre-processed for each implant according to the relief of the patient's real bone according to conic-beam computed tomography and prepared by 3D printing from titanium alloy. During installation, ring device freely put on neck of implant, then hooks are accurately hammered into a spongy bone and the device is fixed by means of at least two screws from the titanium alloy introduced through holes in plates of the device accordingly: one in lingual and one in a labial cortical bone, and fixation of a prosthesis to a beam by means of screws is carried out with restriction of effort 35 N/cm.

EFFECT: method allows improving reliability, providing quality and predictability of direct implantation prosthetic using beam-like arched structure at its setting in bone of low quality due to effective stabilization of support implants.
