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. Two incisions are made. The first, on the eve of the oral cavity, horizontally to the bone, along the transitional fold, in the area of ​​the premolars, is performed equal to the width of the raspator. Through the incision made by the raspator, all soft tissues are displaced together with the periosteum until the surgical field is completely exposed, then the second incision is made up to 2 cm long along the alveolar ridge of the upper jaw in the projection of the implant installation 5 mm from the edge of the keratinized gum for the subsequent formation of a cuff around the implant. Then, through the first incision, the trajectory of the zygomatic implant installation is marked with a marker on the bone; for this, a line is drawn connecting the 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 second incision. Through the second incision, 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 intended point on the outer surface of the zygomatic bone on the implant positioning trajectory previously marked with a marker. The drilling axis is determined 4-5 mm along the plane of the drawn trajectory perpendicularly into the depth of the cheekbone from the positioned end of the cutter. Before starting further drilling of the channel, the cutter is brought back along the drawn trajectory into the infraorbital fossa at the point of the beginning of the drilling of the canal. A channel is drilled. The zygomatic implant is placed through the second incision to a depth optimal for subsequent screw-retained orthopedic rehabilitation. The implant placement is controlled through the first incision. Sutures are applied to seal the operating field.

EFFECT: method provides 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 by performing measures for the preparation of bone tissue, the process implantation of dental implants into the jawbone and actions to shape the gums.
