“…In this context, experimental approaches using chewing simulators could provide significant insights into the effects of molar morphology on chewing efficiency. Chewing simulators have been used to investigate oral processing of manufactured food (Salles et al, 2007;Arvisenet et al, 2008;Mishellany-Dutour, 2011;Chen et al, 2022) or the effect of chewing on dental wear (Kern et al, 1999;Karme et al, 2016;Jeannin et al, 2019;Alemzadeh, 2020;Krueger et al, 2021). Other devices modelling vertical movements have been used to test the effect of dental morphology on food fracturing (Lucas et al, 1994;Evans and Sanson, 1998;Anderson and LaBarbera, 2008;Berthaume et al, 2010), but to our knowledge, there has been no attempt to simulate food fracturing during non-vertical chewing motion.…”

Bulletins et Mémoires de la Société d' Anthropologie de ParisCette note fait suite à une communication présentée lors des 1846 es journées de la Société d'Anthropologie de Paris dans le cadre de la session "Humanité(s) : définition(s), diversités et limites" Abstract -Mammalian molars play a central role during chewing, or food comminution, through cyclic dental occlusion. Mammals fragment food items with varying degrees of efficiency depending on their dental morphology, suggesting an adaptive link that is yet to be assessed. Here, we test the effect of molar morphology at maximum intercuspation (centric occlusion), i.e., between phases I and II, on the comminution of five food items that correspond to different mechanical challenges encountered by catarrhines. Using a chewing simulator, we experimentally measured the number of food fragments produced after five successive intercuspations with two different forces, in order to assess their influence. The sample includes cercopithecid and hominid specimens encompassing the main dental occlusal patterns and dietary habits displayed by extant and fossil catarrhines. We show that increasing bite force results in better food item degradation overall although we report some exceptions, notably for ductile and tough foods (apples, ginger and leaves). Brittle and complex foods (hazelnuts and crickets) are fragmented by intercuspation. This experiment showed that proper occlusion and bite force are sufficient only to fragment brittle food and that additional movements are necessary to fragment tough foods (leaves and grasses). It also highlights the masticatory capacities of various occlusal patterns in primates and our ability to test these with robotics, a breakthrough that will allow investigations of important anthropological questions concerning the evolution of dental morphology.

The last decade (2010-2021) has witnessed the evolution of robotic applications in orthodontics. This review scopes and analyzes published orthodontic literature in eight different domains: (1) robotic dental assistants; (2) robotics in diagnosis and simulation of orthodontic problems; (3) robotics in orthodontic patient education, teaching, and training; (4) wire bending and customized appliance robotics; (5) nanorobots/microrobots for acceleration of tooth movement and for remote monitoring; (6) robotics in maxillofacial surgeries and implant placement; (7) automated aligner production robotics; and (8) TMD rehabilitative robotics. A total of 1,150 records were searched, of which 124 potentially relevant articles were retrieved in full. 87 studies met the selection criteria following screening and were included in the scoping review. The review found that studies pertaining to arch wire bending and customized appliance robots, simulative robots for diagnosis, and surgical robots have been important areas of research in the last decade (32%, 22%, and 16%). Rehabilitative robots and nanorobots are quite promising and have been considerably reported in the orthodontic literature (13%, 9%). On the other hand, assistive robots, automated aligner production robots, and patient robots need more scientific data to be gathered in the future (1%, 1%, and 6%). Technological readiness of different robotic applications in orthodontics was further assessed. The presented eight domains of robotic technologies were assigned to an estimated technological readiness level according to the information given in the publications. Wire bending robots, TMD robots, nanorobots, and aligner production robots have reached the highest levels of technological readiness: 9; diagnostic robots and patient robots reached level 7, whereas surgical robots and assistive robots reached lower levels of readiness: 4 and 3, respectively.

“…A chewing robot in an oral context has been found in many applications regarding the emotion and expression of social robotics, the analysis of the chewing process, dental and joint prosthetic material tests and food science [1][2][3][4][5]. In order to design a high anthropomorphic chewing robot, the working principle of human masticatory system should be studied.…”

A Redundantly Actuated Chewing Robot Based on Human Musculoskeletal Biomechanics: Differential Kinematics, Stiffness Analysis, Driving Force Optimization and Experiment

Human masticatory system exhibits optimal stiffness, energy efficiency and chewing forces needed for the food breakdown due to its unique musculoskeletal actuation redundancy. We have proposed a 6PUS-2HKP (6 prismatic-universal-spherical chains, 2 higher kinematic pairs) redundantly actuated parallel robot (RAPR) based on its musculoskeletal biomechanics. This paper studies the stiffness and optimization of driving force of the bio-inspired redundantly actuated chewing robot. To understand the effect of the point-contact HKP acting on the RAPR performance, the stiffness of the RAPR is estimated based on the derived dimensionally homogeneous Jacobian matrix. In analyzing the influence of the HKP on robot dynamics, the driving forces of six prismatic joints are optimized by adopting the pseudo-inverse optimization method. Numerical results show that the 6PUS-2HKP RAPR has better stiffness performance and more homogenous driving power than its non-redundant 6-PUS counterpart, verifying the benefits that the point-contact HKP brings to the RAPR. Experiments are carried out to measure the temporomandibular joint (TMJ) force and the occlusal force that the robot can generate. The relationship between these two forces in a typical chewing movement is studied. The simulation and experimental results reveal that the existence of TMJs in human masticatory system can provide more homogenous and more efficient chewing force transmission.
