Nowadays, 3D printing technology has become a baby in the medical field with outstanding contributions. There are many more medical materials. Medical metal materials for surgical implants and orthopaedic devices: stainless steel, cobalt-based alloys and titanium alloys. Titanium alloys are the most common materials used in the clinical application of hard tissue implants. Due to its good biocompatibility and mechanical properties, it is also the most ideal material for internal implants. Medical titanium plates, titanium nails, and titanium mesh have been widely used for oral and maxillofacial trauma, internal fixation, and resection of maxillofacial tissues including jaws, mandibles, osseous walls, craniums, emulsions, and so on. It is also possible to fabricate a skull for skull replenishment, and microporous titanium mesh netting for repair of damaged skull caps and dura mater. Oral production of implants, personalised foundations, dentin brackets, crowns and bridges and other areas in the field of oral implantology, orthodontics, etc.. Ski-mandibloy tissues for implantation of sedentary materials and methods of preparation are the main factors influencing the quality of the restoration. Successful maxillofacial restorative and reconstructive surgery is also critical.
Since the 1940s, many scholars have studied the performance relevance of titanium bioperformance. The studies involve several disciplines such as physical, chemical, biomedical and advanced electron microscopy and biochemical analysis. Ensuring the presence of good biocompatibility, mechanical compatibility, and appropriate standards for titanium implants such as methodology, and development of surgical implants is critical.
Research on titanium implant materials for internal human surfaces includes:
(1) Improvement of existing and development of new surface activation methods to enhance the wear and corrosion resistance properties of implanted materials, and to further improve the compatibility of titanium alloy materials and bromothalamus mineral concentrations; (2) Improvement of existing and development of new surface activation methods to enhance the wear and corrosion resistance properties of implanted materials.
(2) Personalised custom 3D mesh implant design and preparation.
With regard to hard tissue repair and replacement materials 3D mesh titanium alloy implantation 3D metal printing research is a comprehensive field spanning multiple disciplines. There is a need for better communication among medical professionals and the next research trends are:
(1) CT scan data of different extracranial defects, reconstructed after CAD 3D porous structure implants for personalised design design;.
(2) In the design of mesh structure, biochemical simulation analysis bionic design proposes a mesh structure and distribution to meet the sufficient stiffness and strength to solve the problem of pressure shielding, and at the same time, there must be certain advantages to meet the needs of support. It ensures that it will not be deformed and damaged after implantation into the human body;.
(3) Research data information leads to in vitro experimental mechanics and in vivo implantation experiments, adjusting the pore parameters, the mechanical properties of the mesh structure of titanium alloy and the internal surface conditions. The process of clinical implantation will be accelerated.
(4) 3D metal printing technology is used for the fabrication of 3D reticulated titanium alloy stent structures to overcome the increasing number of defects in the traditional fabrication methods of bracket complex shape fabrication and internal microstructures that cannot be controlled without the limitation of the complexity of the bracket geometry, control of the aperture, porosity, and fabrication of the bracket's porosity and microstructures. Furthermore, it is possible to optimise the structure of the pre-stent by means of finite element analysis. Some special requirements are realised, such as improving the mechanical strength of the stent.
