| titleOfInvention | Method of recovering absent tooth with support on dental implant |
| abstract | FIELD: medicine. n SUBSTANCE: invention refers to medicine, namely to dentistry, and is intended for use in soft gingival tissue formation in a near-implanted area and obtaining an accurate imprint of a prosthetic bed. An anaesthesia followed by a linear incision of the gingiva at an apex of the alveolar is performed in the area of the established dental implant after its engraftment. A blind screw is removed, a scan marker is inserted into the dental implant to obtain digital impressions from both jaws by intraoral 3D scanning with subsequent modelling of the individual gingival shaper with a screw channel located inside it, fixing it to the implant, and sub-gingival parts parameters corresponding to clinical situation and antagonists teeth location. Further, according to the obtained digital model, an individual gingival shaper is made. Immediately 1–2 hours after the gum incision, an individual gingival shaper is placed to the dental implant. A hole of the helical channel of the individual gingival shaver is closed with a temporary seal. Gum compression around the individual shaper enables forming the required gum and gingival papilla profile. Parameters of the gingival blood flow are measured in the area of the installed implant, and normalization of its level is used to determine completion of the gum formation process. A digital tooth impression is made with an individual gingival shaper and antagonist teeth. Comparison is carried out in a computer program of a digital model of a previously made individual shaper with a digital model after the gum formation process is completed to assess the gingival level changes during its formation. That is followed by adjusting the level of the ledge taking into account the gingival level changes and modelling the individual abutment with a sub-gingival part completely corresponding to that of the individual shaper with the gingiva level corrected. Then the individual crown abutment digital model is modelled taking into account antagonist teeth. Individual titanium abutment and crown made of zirconium dioxide are made to be fixed in oral cavity. n EFFECT: method allows eliminating the risk of gum injuries when installing the abutment and improving the functional and aesthetic effect. n 1 cl, 1 ex |
