Maxillary sinus lifting side wall fenestration indication guide plate and manufacturing method thereof

Abstract

The invention discloses a maxillary sinus lifting side wall fenestration indication guide plate and a manufacturing method thereof. The technical problems that in the prior art, the maxillary sinus lifting side wall fenestration position and size are not accurate enough, consequently, maxillary sinus lifting side wall fenestration is high in risk and low in efficiency are solved. The maxillary sinus lifting side wall fenestration indication guide plate comprises a base plate and a guide structure detachably connected to the base plate, a connecting bolt body is arranged on the base plate, andthe guide structure is detachably connected to the connecting bolt body. The manufacturing method mainly comprises the steps that stl data are obtained through oral scanning before an operation, CBCTis shot to obtain Dicom data, the maxillary sinus lifting side wall fenestration boundary is calibrated in guide plate design software, a side wall fenestration guide plate and a dental support base plate are designed in guide plate generation software according to the fenestration boundary, and printing forming is conducted through a 3D printer. The maxillary sinus lifting side wall fenestrationposition and size can be accurately determined, the bone mass of the side wall is stored for postoperative reduction, maxillary sinus mucous membrane perforation, injury to adjacent blood vessels andother complications are avoided, the operation risk is reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of medical device structures, and in particular relates to a maxillary sinus lifting side wall fenestration indicating guide plate and a manufacturing method thereof. Background technique [0002] Insufficient bone in the maxillary posterior region is a situation we often encounter in implant surgery. As a common maxillary posterior bone augmentation technique, maxillary sinus lift is widely used. This technique is based on the remaining bone in the posterior region. The difference is divided into the maxillary sinus lift through the alveolar crest and the maxillary sinus lift through the lateral wall. There are many ways to open the side wall through the maxillary sinus through the side wall, such as using ultrasonic osteotome or ball drill to remove the side wall bone and open the window. This method cannot save the side wall bone. At the same time, in actual operation, The position and scope of grinding,...
