This contribution is focused on the influence of build orientation on hardness of materials sintered using direct metal laser sintering (DMLS) technology. It builds on the current research works that has monitored the influence of build orientation on a fatigue life, mechanical properties, roughness after machining, etc. In the mentioned work, a slight influence of build orientation on the above properties was shown. The hardness was measured on a Ti6Al4V alloy which was made of powder by DMLS technology. The individual materials were sintered at different laser powers, then annealed to remove internal stresses. Part of the experiment examined the metallographic analysis of materials in the direction perpendicular to the sintered layers and parallel with the sintered layers. Microhardness was measured on metallographic cross-sections and the results were statistically processed. The influence of laser power on a respective material hardness was assessed by one-way analysis of variance (ANOVA), a comparison of the hardness between sintered and sintered-annealed samples, as well as the comparison of hardness in the two considered directions was performed by t-test and F-test. A statistically significant difference in the hardness of the materials prepared at different laser powers was found. The influence of heat treatment, as well as the direction of material building also showed a statistically significant difference.

“…The mechanical properties of the materials used in the study are shown in Table 1. Titanium alloys are the most attractive metallic materials for biomedical applications, and are used for various implants and dental devices [26]. Ti6Al4V is heterogeneous and used for different medical implants, namely for dental osseo-integrated screws [26].…”

Proposal for a New Bioactive Kinetic Screw in an Implant, Using a Numerical Model

et al. 2022

A new biomechanism, Bioactive Kinetic Screw (BKS) for screws and bone implants created by the first author, is presented using a bone dental implant screw, in which the bone particles, blood, cells, and protein molecules removed during bone drilling are used as a homogeneous autogenous transplant in the same implant site, aiming to obtain primary and secondary bone stability, simplifying the surgical procedure, and improving the healing process. The new BKS is based on complex geometry. In this work, we describe the growth factor (GF) delivery properties and the in situ optimization of the use of the GF in the fixation of bone screws through a dental implant. To describe the drilling process, an explicit dynamic numerical model was created, where the results show a significant impact of the drilling process on the bone material. The simulation demonstrates that the space occupied by the screw causes stress and deformation in the bone during the perforation and removal of the particulate bone, resulting in the accumulation of material removed within the implant screw, filling the limit hole of the drill grooves present on the new BKS.

“…A test of a dental implant performed with 1000 h of immersion in Carter-Brugirard saliva with pH values that simulate the conditions in the oral cavity showed how the protective properties of Ti20Zr were enhanced due to the new phosphate-rich layer that formed at the interface [45]. Other papers [46] focus on the detection of the cause of the Ti6Al4V dental implant's fracture during the cutting process on the basis of its structural and fractographic analysis. Recently, a study of the corrosion resistance of TiZr binary alloys evidenced an interesting finding when correlating the electrochemical results with the composition change.…”

“…The observed superior electrochemical and mechanical properties of Ti50Zr [27] suggest that this material can safely replace Roxolid as a dental implant. It is known that despite the use of a good method of implantation and a suitable treatment after this operation, bone loss can still occur [46,47]. The observed superior electrochemical and mechanical properties of Ti50Zr [27] suggest that this material can safely replace Roxolid as a dental implant.…”

It is known that despite the use of a good method of implantation and a suitable treatment after this operation, bone loss can still occur [46,47]. The fracture of the central screw and other implant parts was investigated and the results showed that implant failure is mainly caused by mechanical aspects [48,49], such as fatigue or overload with high-level cyclic stresses.…”

The Trends of TiZr Alloy Research as a Viable Alternative for Ti and Ti16 Zr Roxolid Dental Implants

et al. 2020

Despite many discussions about Ti versus Zr, Ti remains the golden standard for dental implants. With the extended use of implants, their rejection in peri-implantitis due to material properties is going to be an important part of oral health problems. Extended use of implants leading to a statistical increase in implant rejection associated with peri-implantitis raises concerns in selecting better implant materials. In this context, starting in the last decade, investigation and use of TiZr alloys as alternatives for Ti in oral dentistry became increasingly more viable. Based on existing new results for Ti16Zr (Roxolid) implants and Ti50Zr alloy behaviour in oral environments, this paper presents the trends of research concerning the electrochemical stability, mechanical, and biological properties of this alloy with treated and untreated surfaces. The surface treatments were mostly performed by anodizing the alloy in various conditions as a non-sophisticated and cheap procedure, leading to nanostructures such as nanopores and nanotubes. The drug loading and release from nanostructured Ti50Zr as an important perspective in oral implant applications is discussed and promoted as well.
