In dental implant insertion, an artificial foundation is prepared for the prosthetic device, which involves the surgical positioning of the implant in the jaw bone. The success of dental implants relies on the osseointegration process. The biomechanical factors, such as stress and strain, developed during the insertion affect the jawbone and its surroundings. In this current study, the stresses during the implant insertion in the mandibular jawbone bone are analyzed using three-dimensional explicit dynamic analysis, and the Cowper–Symonds model is implemented with the damage model. The implant’s design has a substantial impact on stress distribution within the cancellous bone during the insertion procedure. The stress variation takes place as the implant moves into the pre-drilled hole. This is because of the contact between the bone and the fixture on the implant. The upper edge of the predrilled site shows that the stresses are more at the crestal region of the implant due to surface area. There is a gradual increase in the stress level as the implant reaches the lower edge from the top edge. This is because of the concept of mechanical interlocking. Clinicians can use this information to anticipate and address potential stress-related challenges during implant placement.

“…These small foreign particles, which generally have arbitrary angular shapes, move in a fluid, especially in the airjet for dry micro-blasting, consecutively strike solid targets and cause material degradation. This type of damage occurs on the surface of the components, called solid particle erosion (SPE) [1][2][3].…”

“…They conducted experiments to verify the models and found out that a surface material can be removed by chip formation with maximum erosion rate, by using an optimal angle of impact. There are some other simulations in the field of SPE due to the dry micro-blasting process based on the SPH method, such as Takaffoli and Papini [41] and Khoddami et al [1]. However, there is no criterion to determine when the FE method is better or the SPH for multiple angular impacts simulation.…”

Micro-blasting is a general process for surface treatment of engineering components such as gears, dental implants, and screws. These components are put under solid particle impacts. To attain the acceptable final surface, it is important to present an accurate and fast prediction of erosion rate and other surface damage mechanisms of them under various conditions. To reduce the computational costs, this article aims to present a beneficial 3D model using representative volume element (RVE) technique for the simulation of multiple arbitrary angular solid particle erosion (SPE). This technique is used in finite element (FE) method in comparison with smoothed particle hydrodynamics (SPH) to investigate their capability in SPE modeling. Johnson-Cook constitutive equations are performed to describe the erosive behavior of the titanium alloy. To verify the developed approach, SPE experiments were conducted on Ti-6Al-4V under various values of impact angle and particle velocity. Then, the effects of the impact angle on erosion rates are investigated to identify the critical angle in which the erosion rate is maximum. Moreover, an approximate equation is presented for variations of erosion rate. The article focuses on the erosion effect on the surface of the alloy by investigating SPE mechanisms. The results show the RVE approach, as well as the approximate equation, can predict the wear damage in a good agreement with the empirical data. SPH showed more accurate results in higher velocities, while the FE model is more appropriate in the lower ones. According to the results, the impacting angle of 45̊ is critical.

Traditionally, simulation studies in dentistry have relied on the finite element method (FEM). However, the smoothed particle hydrodynamics (SPH) method, which represents objects as particle collections without the use of meshes, has gained recent attention. Despite its application in dentistry, there is currently a lack of comprehensive literature summarizing the specific applications of the SPH method in the oral region. This review aims to provide a summary of studies that have utilized the SPH method in dentistry, focusing on its applications in analyzing large deformations, such as dental ceramic collisions, soft material analysis (e.g., denture adhesive), and virtual training simulations for dental treatments. By combining the advantages of the SPH and FEM methods, more accurate simulations can be achieved, and further applications of the SPH method in dentistry are anticipated.
