“…This coefficient is the mean adjustment and represents the expected change in response per unit change in the value of the factor if the other factors remain constant. ANOVA analysis is a regression analysis used to investigate the effects of response output factors that find factors that are noted to affect the process, based on the priority confidence intervals in the model [39].…”

Fatigue analysis plays a vital role in determining the structural integrity and life of a dental implant. With the use of such implants on the rise, there is a corresponding increase in the number of implant failures. As such, the aim of this research paper is to investigate the life of 3D-printed dental implants. The dental implants considered in this study were 3D printed according to the direct metal laser sintering (DMLS) method. Additionally, a finite element model was developed to study their performance, while fatigue life was predicted using Fe-Safe software®. The model was validated experimentally by performing fatigue tests. The life of the dental implants was analysed based on Normal strain and the Brown-Miller with Morrow mean correction factor algorithm. The model revealed that there was a strong correlation between the FEA and the experimental results. The clinical success of 3D-printed dental implant experimentally is 20.51 years and computationally under Normal strain is 19.89 years and Brown-Miller with Morrow mean correction factor is 26.82 years.

“…In dentistry, ceramic FGMs were mainly studied for the use as implant abutments. 13,14 For the success of a dental implant's osteointegration, several factors should be considered which include health and bone quality, surgical techniques, implant design, surface characteristic, and the biomaterial and biomechanical factors. 15 Their use as dental implant abutment is due to the higher toughness and the lower modulus of elasticity, increased esthetics, and corrosion resistance.…”

Background: Functionally graded material (FGM) is a smart configuration for designing composite materials to improve their long-term endurance. The main characteristic of an FGM is the gradual variation in composition and microstructure across its dimensions, resulting in enhanced properties. This approach has been applied in several fields of thermal barrier coatings, power industry, biomechanical, automotive, aerospace, mechanical, civil, nuclear, aeronautic, and naval engineering.Aim: This article is intended to provide an overview of the FGMs, their application in dentistry, and the employment of the concept on the mechanical performance of dental restorative systems. Results:A thorough review of FGM dental applications has found that several researchers have been able to develop different configurations based on FGM concept to avoid failures, such as infrastructure, abutment failures in implantology, and prosthodontics. These strategies result in a gradual transition between dissimilar materials decreasing residual stresses generated during fabrication and function. Conclusion:Of late, multiple parallel researches based on the FGM concept are being carried out on dental implants coated with hydroxyapatite (HA), zirconia (Zr), and its oxides to improve osseointegration and reduce stress behavior. This review attempts to present a thorough understanding of FGMs, their characterization, manufacturing techniques and technology, and their dental applications.Clinical significance: Throughout the past decade, the use of endosteal dental implants as a treatment modality of choice in oral rehabilitation cases has increased. Unfortunately, no artificial implants have biomechanical properties equivalent to that of the surrounding bone. Based on FGM concept, a graded composition between titanium and HA/Zr on the implant surface has now been achieved that has resulted in improved mechanical behavior and osseointegration.

“…In previous studies, FGBM implants were usually graded in radial direction [15][16][17][18][19][20]. They showed that employing axial FGBM implants resulted in stress reduction in the implanted bone [14][15][16][17] and biocompatibility improvement in the dental implant system [18][19][20]. As an alternative approach, the gradient can be distributed radially so that the properties of radial FGBM implant varied gradually from a stiffer biomaterial in the center of the implant to a more biocompatible and bioactive material as the outer layer in contact with the hosting bone.…”

Development of new biomaterials such as FGBMs for dental clinical implant applications have been recently attracted a lot of attention due to their advantages and abilities in satisfying both mechanical and biocompatibility properties simultaneously. Drawing inspiration from the geometry of a real dental implant system, and using the properties of radial functionally graded biomaterials, a model was investigated to fabricate the artificial FGBM dental implant under periodic dynamic loads. The investigation is done using a finite element analyzer, and the problem is solved under the actual bone geometry, constraints, conditions and combined dynamic loads. The effects of radial FGBM dental implants on the stress and deformation values near the dental implant-bone interface under periodic dynamic loads are simulated. Response characteristics of FGBM implant models with different heterogeneous biomaterial parameters are determined and compared to the behavior of conventional titanium and titanium coated by a film of hydroxyapatite implants. The results show that using radial FGBM dental implants can improve the mechanical behaviors of dental implant systems regarding stress and deformation. It was also found that FGBM parameters can play an essential role in achieving an efficient biomechanical function in those systems.
