Embodiment 1

[0029] Use computer tomography technology to scan the patient's oral defect, import the 3D modeling software according to the patient's CT or MRI format file, and combine the computer-aided design software to reconstruct the 3D model of the patient's oral defect, and build a more close-fitting model based on the 3D model of the defect. The three-dimensional model of the patient's alveolar bone anatomy was designed, and the dense layer was designed to be 0.8mm thick, and the loose layer was designed to be 0.5mm thick. %, the pore diameter near the inside is 50-80μm, and the porosity is 50%-60%. Generate STL files, write data processing software for the alveolar bone, and process the STL files in layers, process cross-section information, and generate computer-recognized language; set the printing speed to 2mm / s, and the printing layer thickness to 0.12mm . Lay pure PEEK material on the substrate of the printing platform, use the high energy of the laser to sinter and shape the...

Abstract

The invention relates to a PEEK alveolar bone repairing material and an individualization producing method, and belongs to the field of polymer materials and biological medicine engineering. The PEEKalveolar bone repairing material is a polymer material which is composed of an outer compact layer and an inner loose layer, the compact layer can prevent peripheral soft tissues from growing into a bone defect area to form fibrous connective tissues, a bottom loose layer is provided with a through sponge porous structure, the hole structure gradually becomes larger from outside to inside, and thestructure can absorb and release active substances sustainably to promote the growth of bone tissues. A 3D printing technology is adopted by the material to form a repairing material which is highlymatched with the height of an alveolar bone. The PEEK alveolar bone repairing material has the advantages that the PEEK alveolar bone repairing material has better biological compatibility, the PEEK alveolar bone repairing material does not easily drop in the using process, can adapt to cold and hot environments in an oral cavity and can be individually produced according to the demands of a patient, the surgical operation time is greatly shortened, and the PEEK alveolar bone repairing material has good application prospects in alveolar bone regeneration of the department of stomatology.

Description

technical field [0001] The invention belongs to the fields of polymer materials and biomedical engineering, and specifically relates to a polyether ether ketone alveolar bone repair material and a personalized manufacturing method. Background technique [0002] Loss or defect of dentition will cause patients to be unable to chew or chewing efficiency will decrease, often accompanied by alveolar bone height and width defects, and can cause damage to facial shape and temporomandibular joints. The application of guided bone regeneration (Guided bone regeneration, GBR) can prevent the occurrence of bone resorption after tooth extraction, reduce the adverse effects on the alveolar bone of adjacent teeth, and provide good alveolar bone conditions for later denture restoration. Guided bone regeneration. GBR technology refers to the biofilm made of biological materials, which artificially erects a biological barrier between the soft tissue of the gums and the bone tissue, preventing...
