METHOD FOR ONE-STAGE IMPLANTATION AND DENTAL IMPLANT Russian patent published in 2022 - IPC A61C8/00 

FIELD: dentistry and orthodontics.

SUBSTANCE: invention relates to the field of dentistry and orthodontics, namely to dental implants for one-stage implantation. Clinical examination is carried out, clinical examination results are analyzed, treatment is planned, implant size is selected, implant site is prepared and implant is placed. They form a mucosa. The subsequent modeling of the prosthesis with the gingival part and the tooth and the installation of the prosthesis with fixation on the implant are carried out. At the same time, the preparation of the bed is carried out using two cutters, the first of which with a diameter equal to the diameter of the dental implant pin in its wide endosseous part, pass in the jawbone at the site of the proposed implant installation to a depth of 2-3 mm, which is due to the thickness of the periosteum and dense bone tissue. The second cutter with a diameter smaller than that of the first one is used to form the final channel in the bone for the installation of an implant containing an endosseous part with a thread, a transmucosal part and an abutment, coaxially connected in a single sequence and forming a single piece, while along the restoration site along the perimeter of the seating part of the abutment, horizontal groove, a vertical hole with an internal thread corresponding to the thread of the prosthesis fastening screw is made from the end of the abutment, the endosseous part of the implant consists of an apical section, which occupies 0.5-0.7 of the length of the endosseous part and a coronal section, which occupies 0.5-0.3 the length of the endosseous part, while the apical section is made in the form of a cone with an opening angle of 10 to 20 degrees, and the coronal section is made in the form of a truncated inverse cone, the base of which is common with the base of the apical section. The endosseous part of the implant is immersed in the bone and the angle of inclination of the implant abutment relative to its endosseous part is adjusted by bending the implant in the transmucosal part, while making an impression of the mucosa and a tooth blank, they are modeled and adjusted directly in the patient's oral cavity, taking into account the morphofunctional relationships of tissues and organs of his dentoalveolar system, including adjusting the angle of inclination of the abutment relative to the endosseous part of the implant.

EFFECT: inventions make it possible to carry out effective one-stage implantation and reduce the time for its implementation; use of the design of the proposed implant allows one-stage implantation of implants without opening the abutment after the healing of the mucosa.
