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.

“…Even though the problem is complex, it is broken into simple sub-units to be handled using the FEA method, and every structure is resolved independently by being divided into several discrete pieces known as finite elements. The concept of moving from piece to piece is used to solve the problem, which is made easier by the use of numerous tiny, interconnected pieces [11,12]. Finite element analysis has several advantages.…”

Finite element analysis (FEA) has been used to evaluate dental implant designs, superstructure structure; material, and surrounding bone stability. According to PubMed, and Google scholar, much FEA research on dental implants was published between 1988 and 2022. Finite element analysis is an advanced technology used to examine implant-abutment links, dental implant design, and implant screw architecture to verify its usability and dependability in the field of dental implantology. The purpose of this FEA literature study was to go over the concept applications of the finite element method (FEM) in dental implantology. Many health-related problems, notably in dental implantology, can be swiftly and simply solved utilizing finite element methods, which combine strength, stress, material science, and architecture. Finite element methods not only give speedy and reliable data on the patients under investigation, but they also act as essential guidance for many clinical trials. To have a better understanding of the finite element modelling method. For many years, the FEA approach has been employed in medicine and is frequently used in the study of dental implantology. It is a useful tool for permitting endless replication of studies that cannot be duplicated clinically in one-to-one circumstances in various settings.

“…Aim of this work is to study the biomechanical behaviour of three different endosseous dental implants and the development of a new parametric numerical model [17,25] to simulate different levels of osseointegration in order to evaluate the stress distribution on the bone-implant interface at different times, also to evaluate an early use of the dental implants [26,27].…”

“…To evaluate the von Mises stress distributions at different times after the surgery, a new parametric numerical model [17,25] has been developed. In particular, the solid model of the bone-implant interface has been suitably subdivided into two different cylindrical regions ("inner" and "outer") to which different mechanical characteristics can be assigned (Fig.…”

Tooth loss is a common pathology that affects many people. Dental osseointegrated implants are the ideal solution to restore normal functionality in partially or completely edentulous patients. The not perfect osseointegration and the fixture fracture are the main causes of failure for these kinds of implant. To avoid these drawbacks, several studies have been conducted to analyse the behaviour of dental implants. Aim of this work is to analyse the biomechanical behaviour of three different endosseous dental implants. For this purpose, a new numerical model has been developed to simulate different levels of osseointegration and to evaluate the stress values on the bone at different times. In this way, it can be investigated the possibility of anticipating the use of dental implants that usually is delayed three months after surgery. Obtained results confirm the validity of the proposed approach and can provide useful guidelines for dentists.
