“…The surface interactions between cortical bone, miniplates, and screws and between fracture segments were defined as "hard" contacts, with a penalty static friction coefficient of 0.3. (35,(39)(40)(41)(42) Like the healthy control, all FEMs were solved using in Abaqus CAE default implicit direct static solver (Dassault Systémes) (Fig. 2E).…”

Fracture Fixation Technique and Chewing Side Impact Jaw Mechanics in Mandible Fracture Repair

Lower jaw (mandible) fractures significantly impact patient health and well-being due to pain and difficulty eating, but the best technique for repairing the most common subtype-angle fractures-and rehabilitating mastication is unknown. Our study is the first to use realistic in silico simulation of chewing to quantify the effects of Champy and biplanar techniques of angle fracture fixation. We show that more rigid, biplanar fixation results in lower strain magnitudes in the miniplates, the bone around the screws, and in the fracture zone, and that the mandibular strain regime approximates the unfractured condition. Importantly, the strain regime in the fracture zone is affected by chewing laterality, suggesting that both fixation type and the patient's post-fixation masticatory pattern-ipsi-or contralateral to the fracture-impact the bone healing environment. Our study calls for further investigation of the impact of fixation technique on chewing behavior. Research that combines in vivo and in silico approaches can link jaw mechanics to bone healing and yield more definitive recommendations for fixation, hardware, and postoperative rehabilitation to improve outcomes.

“…However, with increasing load, yielding will occur and the bone will deform permanently, with the risk of increasing bone wear. Currently, the tribomechanical behaviour at the bone-implant interface can only be measured experimentally as bone-implant contact mechanics at the scale of asperities is yet only poorly understood (Voutat et al, 2019). The aim of the current work is to contribute to modelling of the bone-implant interface interactions, focussing on predicting the dynamic coefficient of friction (COF).…”

There are many situations where biological materials, such as the skin, come into contact with non-living materials, whether they are man-made or not. These contacts are particularly important when considering the functionality, health, and longevity of medical implants, prostheses, and orthoses, where the frictional behaviour plays a crucial role.Het gepresenteerde werk draagt bij aan een beter begrip van het tribologisch gedrag van biomechanische interfaces. De verkregen resultaten, gebaseerd op experimentele evaluatie op laboratoriumschaal, hebben waardevolle inzichten geboden in de wrijvingsmechanismen die aanwezig zijn in biomedische implantaten, protheses en orthopedische hulpmiddelen, en dragen bij aan de toepasbaarheid en levensduur van deze medische apparaten.
