Problems solved by technology

However, because the mechanical properties of PEKK are still relatively weak compared with the mandible, the traditional structural design of it may cause its collapse under normal physiological loads, so it must be optimized to have a reinforced structure. The in-body mechanical strength is sufficient to support the load

Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings.

[0058] refer to Figure 1-Figure 17 , a method for designing and manufacturing a PEKK personalized implant for mandibular body box-shaped defect repair, said method comprising the following steps:

[0059] 1) Image acquisition and 3D model establishment, the process is as follows:

[0060] 1.1) Obtain the patient's oral and maxillofacial CT image, and use medical image processing software such as Mimics to reconstruct the patient's mandibular three-dimensional model, such as figure 2 As shown, the reconstruction model also includes important anatomical structures such as the mandibular nerve canal, and the lesion area is determined21;

[0061] 1.2) According to the lesion area on the three-dimensional model, the resection plan of the patient's lesion area is designed to obtain a mandibular model with a box-shaped defect of the mandible body, such as image 3 As sho...

Abstract

The invention discloses a PEKK individualized implant design and manufacture method for reconstruction of a mandible box defect. The PEKK individualized implant design and manufacture method includesthe following steps that (1) establishment of image acquisition and a three-dimensional model is conducted; (2) determination and design of abutment position are conducted; (3) design of a fixed unitis conducted; (4) design of a support unit is conducted; (5) design of a boundary grid surface is conducted; (6) the support unit, a fixed unit, the boundary grid surface and a base are combined through boolean operation, and the three-dimensional model of the PEKK implant is obtained; (7) the implant is integrally printed to be shaped and a guide plate of a resection operation in an inpatient ward are printed out at the same time by a 3D printing technology; and 8) the post-processing is conducted, and a PEKK individualized implant with functions of bone reconstruction and dental implant repair can be used clinically and used for the reconstruction of the mandible box defect is obtained. The invention further provides the PEKK individualized implant for the reconstruction of the mandiblebox defect. According to the PEKK individualized implant design and manufacture method and the PEKK individualized implant, the mechanical strength is enough to support the load, enough pore space isprovided used for transmitting a biological agent, and inward growth of bones can be stimulated.

Description

technical field [0001] The invention relates to a method for designing and manufacturing a PEKK individualized implant for mandibular body box-shaped defect repair, which has the functions of bone reconstruction and dental implant repair, and the implant. Background technique [0002] The mandible constitutes the bony support of the lower 1 / 3 of the face. It is the main support structure of the face and the only movable bone in the face. It is the key to maintaining the shape of the face and maintaining chewing and other functions. At present, mandibular defects are relatively common in craniofacial defects. Clinically, jaw disease, tumor resection, trauma, etc. can all cause mandibular defects. Mandibular defects not only affect the aesthetics of the maxillofacial, normal occlusal and language functions, reduce the quality of life of patients, but also have a certain impact on the physical and mental health of patients. [0003] Mandibular defects are divided into segment...
