“…Thus, the patients' concerns about the final facial appearance at the start of treatment are anticipated. On the other hand, the different maneuvers currently available for treatment of orthognathic cases have different outcomes on facial esthetics [17].…”

Objective: The purpose of this study was to evaluate soft tissue parameters for adults, and applying a new method for soft tissue analysis to provide good diagnosis and treatment planning. Material and methods: Cephalometric radiograph of 100 adult subjects randomly selected with accepted facial proportions and normal occlusion aged 18e25 years. It's evaluated with Legan and Burstone analysis and compared with their study on white sample. Results: Egyptian population group were found to have more convex faces, protrusive lips and acute nasolabial angles. Males had more convex faces and protrusive lips than females. It can be concluded that the Egyptian populations group had significant deviations from the White standard soft tissue.

“…Simulations are typically executed on volumetric meshes, but some works use also surface meshes [ 10 ]. The volumetric mesh can be either tetrahedral [ 6 , 9 , 11 , 13 , 14 , 32 ] or hexahedral [ 12 , 31 ]. The number of elements and nodes is normally around some thousands [ 6 , 12 , 31 ] but can go up to a million [ 14 ].…”

“…The materials used in simulation vary between homogeneous linear elastic materials [ 6 , 10 , 32 ], heterogeneous linear materials that separate muscle and adipose tissue [ 11 , 12 , 13 , 31 ], or nonlinear materials [ 6 , 35 ]. Some studies take into account viscoelasticity [ 14 ] and different parameters values [ 13 ] to reach optimum simulation results.…”

“…The most accurate models consider tissue groups such as fixed, free, bonded or sliding [ 11 , 31 ]. Only a few works take into account the sliding effect between the lips and the teeth [ 8 , 11 , 32 ]. The displacement applied to the bones may depend on the test case, such as only the maxilla [ 13 , 14 ], only the mandible [ 35 ], or both [ 6 , 8 , 9 , 10 , 11 , 36 ].…”

Simulation technologies offer interesting opportunities for computer planning of orthognathic surgery. However, the methods used to date require tedious set up of simulation meshes based on patient imaging data, and they rely on complex simulation models that require long computations. In this work, we propose a modeling and simulation methodology that addresses model set up and runtime simulation in a holistic manner. We pay special attention to modeling the coupling of rigid-bone and soft-tissue components of the facial model, such that the resulting model is computationally simple yet accurate. The proposed simulation methodology has been evaluated on a cohort of 10 patients of orthognathic surgery, comparing quantitatively simulation results to post-operative scans. The results suggest that the proposed simulation methods admit the use of coarse simulation meshes, with planning computation times of less than 10 seconds in most cases, and with clinically viable accuracy.
