METHOD OF FIXING SOFT TISSUE GRAFT WHEN CLOSING WOUND AROUND HEALING ABUTMENT Russian patent published in 2025 - IPC A61B17/06 A61C8/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, particularly to surgical and orthopaedic dentistry. Soft tissue graft is placed in the wound cavity in the space between the gum and the gum former. It is spread along the width and depth of the cavity by centring its position relative to the vertical axis of the implant with the attached gingiva former. Surgical needle with a suture material is successively passed through the following points located on the medial side of the implant, located closer to the frontal plane of the oral cavity: through the prick in from the outer side of the wound to a point located on the vestibular surface of gum at 5-6 mm from the gum incision, and prick out through the inner side of the wound to a point located on the oral surface of gum at 2-3 mm from the incision. Further, through the prick in from the outer side of the wound to a point located on the vestibular surface of gum 2-3 mm from the incision, and prick out through the inner side of the wound to a point located on the oral surface of gum at 5-6 mm from the incision. Further, the needle with the suture material is transferred to the distal side of the implant, which is located closer to the posterior part of the oral cavity, and successively passed through the following points located on the distal side of the implant: through the prick in from the outer side of the wound to a point located on the oral surface of gum at 5-6 mm from the incision, and prick out through the inner side of the wound to a point located on the vestibular surface of gum at 2-3 mm from the incision. Further, through the prick in from the outer side of the wound to a point located on the oral surface at 2-3 mm from the incision, and prick out from the inner side of the wound to a point located on the vestibular surface of gum at 5-6 mm from the incision. Wound edges are brought together by pulling the ends of the suture material from the medial and distal sides of the implant. Ends of the suture material are connected from the side of the vestibular surface of the gums and fixed by knotting.

EFFECT: method enables fixing and stabilizing the soft tissue graft, providing a tight coverage of the gum former with soft tissues and the graft in the depth of the wound and on its surface, providing blind closure of the wound, reducing the invasiveness of the procedure.
