ALVEOLAR BONE SPLITTING METHOD FOR DENTAL IMPLANTATION Russian patent published in 2023 - IPC A61C8/00 A61B17/56 A61B6/03 G16H20/40 

FIELD: medicine; dentistry.

SUBSTANCE: invention can be used to create additional bone volume for dental implants. Computed tomography of the maxillofacial area, scanning the model of the patient's jaw, and combining the data on the reference points are performed. Using a computer program, a virtual installation of one dental implant or a group of dental implants is performed in parallel to each other. The implants axes divide the alveolar ridge into two equal symmetrical halves. Using a computer program, a surgical sleeveless navigation template is simulated. The virtual position of the implant is transferred to the patient's jawbone. The computer program is used to model the guide slot along the axis of the implants to be installed and in the middle of the alveolar bone. The alveolar bone is cut with a piezosurgical apparatus in the mediodistal direction. Using a computer program, modeling is performed from the medial and distal sides of vertical beacons corresponding to the axis of the installed implants and the middle of the alveolar bone. The alveolar bone is cut with a piezosurgical apparatus in the vertical direction. A surgical navigation template with a guide groove and vertical beacons is made on a 3D printer from a biocompatible photopolymer. A surgical navigation template is applied to the surgical field. A gum incision is made along the top of the alveolar ridge, vertical drilling to a predetermined depth according to sleeveless guides, and a mediodistal cut of the alveolar bone with a piezosurgical apparatus according to the guide groove and vertical beacons. A flat raspator is installed in the resulting cut and the bone is split. Dental implants are installed in a given digital position according to sleeveless guides.

EFFECT: method allows to perform a predictable minimally invasive splitting of the alveolar bone to create additional bone volume for the installation of dental implants.
