Problems solved by technology

[0007] In order to solve the current mandibular defect repair, autologous bone grafts have increased new trauma at the donor site, insufficient bone volume, difficulty in shaping, insufficient consideration of occlusal reconstruction, and the excessively high elastic modulus of metal implants, resulting in " Stress shielding” makes the implant loose, and even the repair fails. The present invention provides a plastic unit, a fixation unit and Manufacturing method and implant of personalized composite structure implant composed of support unit and growth unit of internal degradable scaffold capable of guiding new bone formation

Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings.

[0055] refer to Figure 1 to Figure 15 A method for manufacturing a mandibular implant with a PEKK support fixation unit and a tissue engineering growth unit comprises the following steps:

[0056] 1) Image acquisition and 3D model establishment:

[0057] ① Collect image data of the patient's mandible. The data can be collected by CT / MRI and other means. Taking CT as an example, spiral CT thin-slice scanning can be used, and the tomographic data can be stored in a storage device in DICOM format after scanning.

[0058] ②Reconstruct the mandible model of the patient. Import the image data of the patient's mandible into medical image processing software, such as Mimics software from Materlise Company, to perform 3D reconstruction of the mandible model, and reconstruct important anatomical structures such as tooth roots and mandibular nerve canal, etc. to analyze and ...

Abstract

The invention provides an implant and a method for manufacturing a mandibular implant with PEKK (polyetherketoneketone) supporting and fixing units and a tissue engineering growth unit. The method includes steps: 1) image acquisition and three-dimensional model establishment; 2) molding unit and fixing unit design; 3) supporting unit design; 4) growth unit design; 5) individual composite-structure implant assembly; 6) individual composite-structure implant manufacturing; 7) in-vitro culture. A molding unit, fixing units, supporting units and the growth unit jointly form an individual composite-structure implant, the supporting units, the fixing units and the molding unit are made of PEKK materials and capable of providing sufficient mechanical strength to keep structural integrity from occlusion functional reconstruction, and the growth unit which is an internally degradable stent is capable of guiding new bone generation.

Description

technical field [0001] The invention relates to the field of mandibular bone repair, in particular to a method for manufacturing a mandibular implant with a PEKK support and fixation unit and a tissue engineering growth unit and the implant. Background technique [0002] The mandible is the largest in volume and area among the maxillofacial bones of the human body, and it is also the only movable bone in the face. As the main supporting structure of the facial shape, the mandible is complex in shape and has strong individual characteristics. At present, mandibular defect caused by trauma, tumor resection and deformity correction has become a common clinical disease. Mandibular defect will affect the patient's swallowing, language, chewing and other functions, and lead to facial deformity and reduce the quality of life. [0003] At present, the main method of clinically repairing mandibular defects is to take bone implants from different parts of the patient's own body for gr...
