“…Among them, autologous bone transplantation is considered to be the "gold standard" in clinical practice; that is, it is the most effective bone-regeneration method [2,3]. However, these two treatments have obvious limitations, such as limited autogenous bone, more pain for patients [4], and immune rejection [5]. In view of this, orthopedic alternatives have rapidly developed in response to clinical needs, including skull prostheses, dental implants, interbody fusion devices, femur prostheses, and tibial prostheses.…”

“…The pore structure creates conditions for processes such as cell adhesion, growth, and reproduction [21], allowing for cell migration, the influx of oxygen and nutrients, and the circulation of body fluids [22,23]. Since the introduction of porous Ti6Al4V bone implants, researchers have been diligently striving to discover a porous implant design that is better suited for promoting bone tissue regeneration [4].…”

As a biomedical material, porous titanium alloy has gained widespread recognition and application within the field of orthopedics. Its remarkable biocompatibility, bioactivity, and mechanical properties establish it as a promising material for facilitating bone regeneration. A well-designed porous structure can lower the material’s modulus while retaining ample strength, rendering it more akin to natural bone tissue. The progression of additive manufacturing (AM) technology has significantly propelled the advancement of porous implants, simplifying the production of such structures. AM allows for the customization of porous implants with various shapes and sizes tailored to individual patients. Additionally, it enables the design of microscopic-scale porous structures to closely mimic natural bone, thus opening up avenues for the development of porous titanium alloy bone implants that can better stimulate bone regeneration. This article reviews the research progress on the structural design and preparation methods of porous titanium alloy bone implants, analyzes the porous structure design parameters that affect the performance of the implant, and discusses the application of porous medical titanium alloys. By comparing the effects of the parameters of different porosity, pore shape, and pore size on implant performance, it was concluded that pore diameters in the range of 500~800 μm and porosity in the range of 70%–90% have better bone-regeneration effects. At the same time, when the pore structure is a diamond, rhombohedral, or cube structure, it has better mechanical properties and bone-regeneration effects, providing a reference range for the application of clinical porous implants.

“…For individuals with remaining terminal dentition or edentulism, immediate-loading full-arch implant rehabilitation is currently the recommended elective treatment method [1]. In recent times, there has been a surge in the utilization of osseointegrated dental implants for the functional and cosmetic restoration of individuals who are either partially or completely edentulous [2,3]. Various factors could impact the long-term success of implants, though.…”

The discovery of the utility of various titanium alloys as implant biomaterials has resulted in these materials becoming far more popular than other metals in the medical world. However, the production of these materials using additive manufacturing has its own challenges some of those being the surface finish that can be used as an implantology material. As such, the purpose of this study is to evaluate the influence of 3D-printed Ti64ELI on the as-built samples printed at 60°, 90°, and 180° orientations. Such studies are very limited, specifically in the development of the laser shock peening surface modification of dental implants. The study showed that each mechanical test that was performed contributes differently to the printing orientation, e.g., some tests yielded better properties when 180° printing orientation was used, and others had poorer properties when a 180° printing orientation was used. It was observed that 60° testing yielded a micro-hardness value of 349.6, and this value was increased by 0.37% when 90° orientation was measured. The lowest HV value was observed under a 180° orientation with 342.2 HV. The core material volume (Vmc) was 0.05266 mm3/mm2 at a 60° orientation, which increased by 11.48% for the 90° orientation. Furthermore, it was observed that the surface roughness (Sa) at 60° orientation was 43.68 μm. This was further increased by 6% when using the 90° orientation.
