DIRECT DENTAL IMPLANTATION METHOD Russian patent published in 2021 - IPC A61C8/00 

FIELD: implantology and orthopedic dentistry.

SUBSTANCE: invention relates to medicine, namely to implantology and orthopedic dentistry, and can be used to replace dentition defects by means of prosthetics using implants. In the system of industrial 3-D modeling, a three-dimensional model of a jaw with a diseased tooth is formed in virtual space. On the virtual model of the jaw with the diseased tooth removed, the installation of the selected dental implant is simulated. The implant placement depth is planned in relation to the individual natural contour of gingival eruption in the area of the extracted tooth on the virtual jaw. On the same virtual model of the jaw with an extracted tooth, virtual modeling of the individual crown of the replacement tooth is performed together with the neck of the tooth and at the same time with the connecting element of the neck of the crown of the replacement tooth with the implant. The length of the connecting element from the contour of the neck of the simulated replacement tooth to its lower end is modeled such that after the crown of the replacement tooth is installed on the implant, the natural contour of the eruption of the replacement tooth corresponds to the individual natural contour of the eruption of the extracted tooth. On the same virtual jaw with an extracted tooth, virtual modeling of an implant template with support on the teeth is performed, with an inner surface congruent with the surface of the gingival mucosa interacting with it in the region of the virtual socket of the extracted tooth and a guide hole above the virtual inlet in the socket of the extracted tooth. The invention relates to medicine, namely to implantology and orthopedic medicine. Above the hole in the template, a guide shaft is modeled coaxially with the position of the virtual dental implant. The guide hole and the shaft are modeled with an inner surface and dimensions that provide the possibility of reciprocating movement of the working part of the dental instrument in it and exclude radial displacements of the working part of the dental instrument during reciprocating movement in it. The height of the shaft makes it possible to make a bed for installing a dental implant to the required depth. Using virtual models using 3D printing technology, an implant template and a crown of a replacement tooth are made. The surgical stage of the method is performed: a diseased tooth is removed from the patient's jaw, a template is placed on the abutment teeth in the jaw in the area of the hole, the working part of the dental instrument, namely the cutter, is placed in the template shaft, and the bed for the implant is prepared in the hole of the extracted tooth. Without removing the template, a dental implant is installed through the shaft into the prepared bed. The template is removed from the jaw. By means of the connecting element of the neck of the replacement tooth with the implant, the finished crown of the replacement tooth is fixed to the implant.

EFFECT: due to the possibility of providing a fixed immersion depth of the implant in the soft tissues of the gums relative to the individual natural contour of the eruption of the gums, due to the possibility of controlled implementation of the planned direction of the bed for the dental implant in the socket of the extracted tooth and the possibility of controlled installation of the dental implant into the prepared bed in the planned direction and on the planned installation depth in relation to the individual natural contour of the gingival eruption allows preserving the individual natural contour of the gingival eruption when installing the crown of the replacement tooth, and also increases the physiology of the method and improve the aesthetics of the results of prosthetics.
