Finite Element Analysis (FEA) for a Different Type of Cono-in Dental Implant

Abstract

The aim of biomechanics applied to implantology is to determine the deformative and tensional states by solving the equilibrium equations within the mandibular bone and the osseointegrated implant to ensure its stability and improve the success rate. The finite element method is a powerful numerical technique that uses computing power to derive approximate solutions for the analysis of components with very complex geometry, loads, materials, and especially the biomechanical problems analysis, which is challenging to find in vivo or in vitro. This study performs a complete FEA survey on 3 implants Cono-in with 3 different diameters 3.4 mm, 4.5 mm, and 5.2 mm with abutments inclined to 15° and evaluates the tensions that are generated in the system as a result of the application of chewing loads. In this study, the extent of the stresses developed in the peri-crestal zone of the implants with the variation of the occlusal overstress acting on them was also evaluated. Autodesk Inventor Nastran Software was used to perform this type of localized finite element analysis; With this type of analysis, it was possible to analyze the peri-crestal area of the implant more precisely through a more accurate reconstruction of the mesh element, which allowed us to solve the FEA solution mathematically. The results showed how the application of the inclined load with respect to the vertical load on a larger diameter system leads to an increase in stress.

Finite Element Analysis (FEA) of a Premaxillary Device: A New Type of Subperiosteal Implant to Treat Severe Atrophy of the Maxilla

“…Overall, although there are multiple advantages to use this method in reproducing approximate and predictive results, numerous randomized clinical trials on this topic must be performed to obtain reliable and definitive results. In addition, other studies are needed to simulate all treatment alternatives for atrophic jaws to include dynamic forces reproducing chewing, to consider the anisotropic and regenerative properties of natural bone, or simply to test other implant designs and prosthetic connections, such as in previous works [ 59 , 60 ].…”

“…Moreover, FEA facilitates the customization of treatments, accurately predicting tooth movement patterns as well as stress and strain distribution [18]. Additionally, in complex oral and maxillofacial surgeries, FEA assists dentists in planning complex procedures, improving outcomes by minimizing risks, and enhancing the effectiveness of different techniques [36][37][38][39][40].…”

Crestal and Subcrestal Placement of Morse Cone Implant–Abutment Connection Implants: An In Vitro Finite Element Analysis (FEA) Study

“…For this study, a D2 bone type was considered according to the classification by Misch [4]. Properties of cortical bone, trabecular bone, and titanium implants were obtained from the literature and other biomechanical studies and assigned to the models [20][21][22][23]. Each solid component was modeled with isotropic, homogeneous, and linearly elastic behaviors to simplify the modeling.…”

“…A three-dimensional (3D) model of the jaw was obtained through a cone-beam computed tomography (CBCT) scan (NewTom Giano HR, Cefla, Imola, Italy) [20,21], as represented in Figure 1. This model was used to extract the accurate geometries of the analyzed b particular attention to the employed cortical thickness of 1.5 mm for the biom study of implants.…”

“…Finite Element Analysis (FEA) studies have proven to be highly valuable for assessing the biomechanical performance of dental implants in various experimental settings [19][20][21][22][23].…”
