METHOD FOR INSTALLING ZYGOMATIC IMPLANTS Russian patent published in 2021 - IPC A61B17/24 A61C8/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to dentistry and orthopedics, and can be used to replace dentition defects by means of prosthetics using implants. Local infiltration anesthesia is performed in the infraorbital area, the outer surface of the zygomatic bone body and in the region of the chewing group of teeth. Then two incisions are made. The first is carried out on the eve of the oral cavity horizontally to the bone, along the transitional fold, in the area of ​​the premolars. The length of the incision is performed equal to the width of the raspator - 2 cm. Through the incision made by the raspator, all soft tissues are displaced together with the periosteum until the surgical field is completely exposed, the trajectory of the zygomatic implant installation is marked with a marker on the bone. For this, a line is drawn connecting a point located on the outer surface of the zygomatic bone 5-7 mm lateral to the edge of the orbit and the point of the intended exit of the implant on the alveolar ridge in the projection of the extraction socket. Through the second incision of the hole of the removed tooth before implantation, the alveolar ridge of the upper jaw is drilled along the planned trajectory with a diamond cylindrical cutter with access to the infraorbital fossa. The entry point into the zygomatic bone is determined based on the preservation of 2-3 mm of the wall between the outer surface of the zygomatic bone and the body of the implant. Through the formed bone canal, the end of a long conical cutter marks the point of drilling the canal on the outer surface of the zygomatic bone on the trajectory of the implant positioning previously marked with a marker. Before starting further drilling of the canal, the cutter is brought back along the drawn trajectory into the infraorbital fossa to the point of the beginning of the canal drilling, which is 4-5 mm deeper than the outer plane of the zygomatic bone. The position of the cutter is controlled through the first cut. A channel is drilled for placing the implant. The zygomatic implant is placed through the socket of the extracted tooth to a depth that is optimal for subsequent screw-retained orthopedic rehabilitation. Stitches are applied.

EFFECT: method ensures minimization of intervention in the middle part of the facial part of the skull, reduction of the operation time, reduction of swelling, pain and severity of the patient's condition in the postoperative period, the possibility of performing an operation on an outpatient basis without the involvement of anesthetic and resuscitation support due to the implementation of measures for the preparation of bone tissue, in the process of implantation of dental implants into the jawbone and actions to form the gums.
