Technical Field

The invention relates to the technical field of oral implantation, in particular to an inclined plane osteotome tool for lifting maxillary sinus for oral implantation.

Background

And (3) lifting the maxillary sinus: the maxillary sinus is a conical cavity in the maxillary body, the bone itself serves as the wall of the maxillary sinus, most of the maxillary sinus is a thin compact bone plate, slightly cancellous bone is arranged in the maxillary sinus, and the thinnest part of the maxillary sinus is only self-compact bone. The inner surface of the bone is directly covered with the mucosa of the maxillary sinus, and blood vessels and nerves reaching the teeth and the periodontal tissue pass through the alveolar canal in the bone or under the mucosa; the maxillary sinus has a shape substantially identical to the maxillary body and can be divided into a base, a tip, and four walls, i.e., front, rear, upper and lower walls. The bottom of the maxillary bone is the nasal surface of the maxillary, the tip of the maxillary bone is embedded into the zygomatic process of the maxilla, the front wall is the front of the maxillary, the back wall is the temporal lower surface of the maxillary, the upper wall is the orbital surface of the maxillary, and the lower wall is the alveolar process; when the maxillary posterior teeth are missing, the bottom wall of the maxillary sinus is lowered to the position of the original root of the missing tooth, and at this time, once the implant is implanted, the maxillary sinus wall can be penetrated, and in order to implant the implant, a synthetic bone substitute is often transplanted to lift the implant to the original position, so that the implant can be ensured to be in the maxillary bone, and the operation process is called maxillary sinus lifting.
