Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] The invention discloses a digital manufacturing method for soft and hard tissue protection jaw pads in oral surgery, which specifically includes the following steps:

[0027] S1. Scan the tomographic data of the patient's head through CBCT. The scanning parameters are 110kVp, 0.7mA, and 3.6s. The scanning range is from the upper edge of the orbit to the lower edge of the mandible. The three-dimensional reconstruction image is obtained through the three-dimensional reconstruction software to ensure the acquisition of the patient's upper and lower jaw bones. Organized DICOM data ( figure 1 );...

Abstract

The invention discloses a digital manufacturing method for soft and hard tissue protection jaw pads in oral surgery. The three-dimensional image of the patient's skull is scanned by CBCT to obtain DICOM data of the patient's upper and lower jaw hard tissues; The stl data of the mandibular dentition; use the open medical imaging software Pro-plan to complete the overlay of the 3D image of the head and the dentition image, and use the reverse engineering software to design the area to protect the jaw pad according to the oral surgery area; import the saved stl file The 3D model of the protective jaw pad was designed in the reverse engineering software Geomagic Studio, and the designed 3D model was printed by a 3D printer. The present invention combines CBCT and dentition scanning three-dimensional images to obtain the patient's upper and lower jaw hard tissue and dentition data, and analyze the data, so as to effectively design a personalized protective jaw pad suitable for the patient according to the patient's surgical area. To deal with the oral conditions of different patients in different states.

Description

technical field [0001] The invention belongs to the technical field of digital design and 3D printing, and in particular relates to a digital manufacturing method for soft and hard tissue protection jaw pads in oral surgery. Background technique [0002] During oral surgery, it is often necessary to open a large mouth, which is commonly used as a metal opener, which is placed directly on the dentition. Due to tooth instability caused by periodontal disease and other reasons, as well as the mobility of the lip and buccal tissues, due to the direct pressure of the metal gag and operational factors during the operation, tooth looseness and soft tissue damage are very common in clinical practice. At present, the commonly used clinical method is to wrap the end of the metal gag with plastic, or use gauze pads to separate the teeth, but it is easy to become loose and unstable during the operation, and it will affect the operation. Contents of the invention [0003] The purpose ...
