Guider for 3D printing for dental implantation and superior maxillary bone integrated reconstruction

Abstract

The invention provides a guider for 3D printing for dental implantation and superior maxillary bone integrated reconstruction. The guider comprises a transplanted bone guide plate, a dental implantation guide hole seat, a first superior maxillary bone fixing plate and a second superior maxillary bone fixing plate, wherein the guide track of the transplanted bone guide plate is consistently matched with a transplanted bone extending track; a plurality of transplanted bone fixing holes connected with transplanted bones are formed in the transplanted bone guide plate; the dental implantation guide hole seat is arranged on the lower side of the transplanted bone guide plate and holes of the dental implantation guide hole seat are opposite to the transplanted bones; the first superior maxillary bone fixing plate and the second superior maxillary bone fixing plate are respectively connected to two ends of the transplanted bone guide plate and are provided with inner side surfaces which are attached to corresponding superior maxillary bone surfaces; and a plurality of superior maxillary bone fixing holes connected with superior maxillary bones are respectively formed in the first superior maxillary bone fixing plate and the second superior maxillary bone fixing plate. By the guider, partial operations, such as implantation hole preparation and implantation of implants, of dental implantation are assisted while a transplanted bone guider guides superior maxillary bone reconstruction surgery.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a 3D printed guide for dental implantation and maxillary integrated reconstruction. Background technique [0002] Tumor invasion, inflammation, trauma and radiation therapy are the main causes of jaw destruction. Surgical treatment often requires resection of a large jaw, which will inevitably lead to facial deformity and loss of occlusal and masticatory functions. This requires sophisticated repair and reconstruction techniques. It is currently the most commonly used method to intercept a non-load-bearing section of fibula from the lower leg and mold it into the shape of the jaw to reconstruct the jaw. [0003] However, at present, most domestic and foreign counterparts focus on the morphology of jaw reconstruction, that is, the recovery of the patient's appearance, but ignore the recovery of the patient's occlusal and masticatory function. In fact, poor occlusal and masticatory f...

Problems solved by technology

[0003] However, at present, most domestic and foreign counterparts focus on the morphology of jaw reconstruction, that is, the recovery of the patient's appearance, but ignore the recovery of the patient's occlusal and masticatory function. In fact, poor occlusal and masticatory function has a greater impact on the patient's quality of life.

We completed a large number of jaw reconstruction cases in the early stage, and successfully restored the patient's appearance, but most of the patients had difficulties with dentures in the later stage, which affected the recovery of occlusal and masticatory functions

Restoration of removable dentures on the transplanted fibula often leads to poor retention and low chewing efficiency, while implants are well retained and are the most ideal way to restore occlusal function, which is beneficial to the dentures, especially the jaws of the implants The reconstruction plan is the goal pursued by oral and maxillofacial surgeons and prosthodontists, but most patients lose their implants due to inaccurate and unreasonable jaw reconstruction positions, or poor implant placement angles or depths Chance
