“…Alumina and zirconia have been used as ceramic fillers for many types of polymer-ceramic composites developed as biomaterials in dental prosthetics [219]. Biofunctional materials, such as silicate glass ceramics, are studied and applied for the regeneration and healing of bone tissue [220], in cancer treatment by hyperthermia [221], in implants [222] or for total replacement in articulating surfaces to promote osseointegration [223]. Larry Hench is one of the pioneers of studies regarding the influence of the chemical structure of bioactive glasses and glass ceramics in general, on the interaction with the physiological system, as well as the connection between the glass surface and the living tissue [224].…”

Biomaterials are mostly any natural and synthetic materials which are compatible from a biological point of view with the human body. Biomaterials are widely used to sustain, increase, reestablish or substitute the biological function of any injured tissue and organ from the human body. Additionally, biomaterials are uninterruptedly in contact with the human body, i.e., tissue, blood and biological fluids. For this reason, an essential feature of biomaterials is their biocompatibility. Consequently, this review summarizes the classification of different types of biomaterials based on their origin, as natural and synthetic ones. Moreover, the advanced applications in pharmaceutical and medical domains are highlighted based on the specific mechanical and physical properties of biomaterials, concerning their use. The high-priority challenges in the field of biomaterials are also discussed, especially those regarding the transfer and implementation of valuable scientific results in medical practice.

“…The choice of friction pair is pivotal, with four options available: metal/PE (Polyethylene), ceramic/PE, metal/metal, and ceramic/ceramic. Notably, the metal/PE bearing, which is the oldest bearing used in industrial prostheses, yields larger particles from PE debris, while the metal/metal and ceramic/ceramic bearing debris generates fewer and smaller particles [7]. Moreover, certain TDR models have a center of rotation located either below or above the disc being replaced, with ceramic/PE and ceramic/ceramic models being most compatible with magnetic resonance imaging (MRI) [8].…”

This study aims to develop an integrated approach for 3D lumbar vertebral biomodel design and analysis, specifically targeting unilevel disc degeneration and the replacement of lumbar artificial discs. Key objectives include improving existing design methods through 3D techniques, inverse modeling, and an engineering biomodel preparation protocol. Additionally, the study evaluates mechanical properties in the implantation area and between disc components to gauge the effectiveness of artificial discs in restoring functional movement within the studied biological model. The construction of a biological model representing the L3–L4 functional spinal unit was based on measurements from radiographic images and computed tomography data obtained from the study sample. The 3D finite element method in Ansys software (v. 19.2, ANSYS, Inc., Canonsburg, PA, USA) was used to monitor the distribution of equivalent stress values within the core of the two artificial discs and the behavior of vertebral bone components in the model. This approach enabled the creation of personalized digital models tailored to the specific implantation requirements of each patient. Stress analysis identified critical areas within the disc cores, suggesting potential design modifications to optimize artificial disc performance, such as selectively increasing core thickness in specific regions and considering adjustments during implantation. For example, preserving part of the lateral annulus fibrosus from the degenerative disc and maintaining the anterior and posterior longitudinal ligaments may play a crucial role in balancing the forces and moments experienced by the lumbar section. This study provides valuable insights into the development of patient-specific solutions for lumbar disc degeneration cases, with the potential for enhancing artificial disc design and implantation techniques for improved functional outcomes.
