In finite element (FE) simulations, the peak bone stresses were higher when loading with a cantilever extension (CE) than when loading without a CE by 33–49% in the cortical bone. In the in vitro experiments, the highest values of principal strain were all within the range of the minimum principal strain, and those peak bone strains were 40–58% greater when loading with a CE than when loading without a CE (p < 0.001). This study investigated how varying the implanted position and angulation of anterior implants in the All-on-Four treatment influenced the biomechanical environment in the alveolar bone around the dental implants. Ten numerical simulations of FE models and three in vitro samples of All-on-Four treatment of dental implants were created to investigate the effects of altering the implanted position and angulation type of anterior implants. A single load of 100 N was applied in the molar region in the presence or absence of a CE of the denture. The 3D FE simulations analyzed the von-Mises stresses in the surrounding cortical bone and trabecular bone. For the in vitro tests, the principal bone strains were recorded by rosette strain gauges and statistically evaluated using the Mann–Whitney U test and the Kruskal–Wallis test. Loading in the presence of a CE of the denture induced the highest bone stress and strain, which were 53–97% greater in the FE simulation and 68–140% in the in vitro experiments (p < 0.008) than when loading without a CE. The bone stresses in the FE models of various implanted positions and angulation types of anterior implants were similar to those in the model of a typical All-on-Four treatment. In vitro tests revealed that the bone strains were significantly higher in the samples with various angulation types of anterior implants (p < 0.008). In the All-on-Four treatment of dental implants, the bone stress and strain were higher when the load was applied to the CE of dentures. Altering the position or angulation of the anterior dental implant in the All-on-Four treatment has no benefit in relieving the stress and strain of the bone around the dental implant.

“…24 Focusing on the treatment planning in maxillofacial trauma patients, FEA can be used to formulate biome chanical justification regarding the position of different plates at the fracture site. 25,26 Using this technology we can now determine the appropriate length of the plate, the number of plates to be used in a particular fracture situation and the number of screws to be used as well. 27 On analyzing the data parameters such as the stiffness of the plates 28 and stability of the fracture fragments, desirable angulations during plate fixation required can also be determined.…”

Quite a bit of interest and evolution has happened in the field of research in the recent times toward analyzing and understanding of trauma and injuries especially that on the human skull and related organs. With the development of faster and latest computers, high fidelity human models have been created to understand the biomechanics of these structures to trauma. In the present article a broad methodology of the fundamentals of model creation and analysis and fracture mechanics has been presented. In particular this paper highlights the methodology of 3D simulation of craniofacial region and an insight to the role of FEA (Finite Element Analysis) in craniofacial trauma. The paper also explains the various steps in computational simulation of the craniofacial skeleton.
