“…Hence two sets of analyses are conducted for four different boundary conditions between disc and bone: i) Normal disc movement, (coefficient of friction 0.0001), free sliding; and ii) Fused jaw bone without any sliding, penetration or separation. The boundary conditions are taken from the literature [22].…”

“…The articular fossa is considered as fixed support and the condyle is allowed to have anterior-posterior linear motion as well as rotation. Resultant force values (Table 2) are assigned from Ingawale et al [22]. For different loading conditions, maximum Von Mises Stress is found at the condylar head.…”

“…It has to be considered that the magnitudes of TMJ forces differ significantly in literature and there are no universally accepted values among researchers on TMJ loading [22]. Due to the presence of conflicting views on the magnitude, type and direction of TMJ forces in literature, researchers use different TMJ loading conditions for finite element modeling.…”

“…Ingawalé and Goswami explained and discussed the temporomandibular joint anatomy [22] and its biomechanics (Indian origin TMJ included) in the book titled Human Musculoskeletal Biomechanics, it extensively details the various methods and techniques as well as hypotheses utilized in the study of the biomechanics of human TMJ. To correctively examine the type and range of TMJ disorder, FEA was carried out simulating the response of TMJs exhibiting a restrictive condylar displacement during the opening and closing movement by Creuillot et al [23] validating the importance of articular disc and functional ligaments in natural motions of TMJ.…”

Temporomandibular joint (TMJ) is anatomically the most intricate joint which connects the lower jaw to the upper jaw and regulates jaw movements. It significantly deals with mastication and speech. It is hence imperative to study the mechanics and functioning of the jaw joint to devise alternative solutions for its replacement whenever required. Further, human skulls are anthropologically categorized into three types – African, Asian and European. Out of these, the Indian skull is also a bit different than its Asian counterparts because of its osteology and skeletal biology. Hence, a comprehensive biomechanical and computational study is essential to provide customized solutions. For the present study, four different loading conditions are selected to perform finite element analysis on the human skull, Anonymized and unidentifiable CT scan data sets from open-source web platforms are converted to STL and then 3D models using 3D slicer. Finite element analysis of jaw joint is carried out. Results based on Von Mises stress studies show significant behavioral differences under varying load conditions. Hence, it is crucial to identify solutions for TMJ disorders of the Indian population.

“…The masseter muscle contributes approximately 43% of the total strength of the jaw closure muscles, the temporalis muscle approximately 36%, and the medial pterygoid muscle approximately 21%. [ 11 12 13 ] Muscle hypertrophy as a result of long-term bruxism often occurs, and most commonly seen in masseter muscle among the masticatory muscles. Masseter hypertrophy described as an asymptomatic unilateral or bilateral volume raise of the masseter muscle.…”

Background: Bruxism is defined as recurrent masticatory muscle activity. Although there is not an agreed treatment method for bruxism, the application of botulinum toxin A (BT-A) has become a reliable lately. This study aimed to evaluate the correlation between the changes in masseter muscle thickness and clenching habits in bruxism patients treated with BT-A. Methods: Twenty-five patients, 23 females and 2 males, diagnosed with possible sleep bruxism were included in the study. The Fonseca Anamnestic Index was applied to the patients to determine their clenching habits and depression levels both before the treatment, and 6 months after it. The masseter muscle thickness was measured using ultrasonography before the treatment and 3 months and 6 months after the treatment. All the patients were injected with a total of 50 U of BT-A, 25 U to each masseter. Results: A statistically significant decrease in masseter muscle thickness was observed in the ultrasonography 3 and 6 months after the BT-A treatment. There was a statistically significant decrease in the Fonseca scores, in which the teeth clenching habits of the patients were evaluated 6 months after the treatment. Although there was a decrease in the depression levels of the patients 6 months after the treatment, this difference was not statistically significant. Conclusion: When the results of this study were evaluated, it was seen that the BT-A injections are an effective, safe, and side effect-free method in the treatment of bruxism and masseter hypertrophy.
