Background
The zygomatic grafting is a tooth implantation technology implanted into zygomatic bones and is mainly used for patients with serious alveolar bone defect in the posterior dental area of the maxilla. The method is a conventional dental implantation restoration technology at present, and has the main advantages of avoiding a large number of bone grafting operations, shortening the treatment period and finishing restoration within 3 months. The zygomatic implant is typically implanted from the palatal side of the alveolar ridge, along the alveolar ridge of the zygomatic or through the maxillary sinus into the zygomatic bone. The ultimate goal of the zygomatic implant is to achieve zygomatic retention, which utilizes dense zygomatic bones of the maxillofacial area to achieve initial implant stability and to reasonably distribute occlusal forces. In addition, in maxillofacial restoration after jaw resection, the zygomatic bone is used for implanting the implant, so that retention is provided for the maxillofacial prosthesis. However, the upper wall of the maxillary sinus is a compact slope, and holes need to be prepared on the cortical bone of the slope during the cheekbone-passing implantation, so that the cheekbone-passing implantation drill is easy to slip off, and the direction and the position of the cheekbone-passing implantation drill are deviated, even serious complications are caused. Through a large number of clinical tests, the ultrasonic osteotome can be used for effectively positioning the slope cortical bone, and then the dental implant drilling preparation hole is completed. But the operation is difficult when the ultrasonic osteotome is commonly used for positioning in clinic at present.
