An assessment of impact strength of the mandible

Biomechanical properties of the body and angle of the sheep mandible under bending loads

“…Similar results were noted in a study that evaluated the regions of the sheep mandible under two different (lateral and ventral) impact loading directions: Under lateral loading conditions, the mandibular angle had been determined to be the weakest region of the mandible, and molar and premolar regions were found more stronger than the angle region (16). In a finite element study, the mandibular angles and condylar necks were found to be the weak areas in the mandibular geometry (17).…”

“…The biomechanical behaviour of the mandible under impact loads has been examined in a few studies. It was found that the mandibular regions have different biomechanical behaviour depending on the direction of load (16) and that some of them are weaker than others (16, 17).…”

Design and experimental evaluation of adjustable bone plates for mandibular fracture fixation

“…Several methods for evaluating stiffness described in the literature use sheep (Alkan et al, 2007;Kovan, 2008) or synthetic mandibles (Fedok et al, 1998;Karoglan et al, 2006) as substrates for bone plate application. There are limitations, however, that prevent consistent and reliable comparison of results, including variation of plate fixation technique among trials and users, and coupling of plate behavior to variations in sheep or synthetic mandible structure.…”

“…75% of fractures occur in males aged 20-30 (Ellis et al, 1985), and are often caused by physical assault; other causes include motor vehicle collisions, falls, and sports-related injury (Craig et al, 2008;Kovan, 2008). Certain fracture patterns predominate, in the mandibular angle and body, as shown in Fig.…”

Capturing the multiscale anatomical shape variability with polyaffine transformation trees

“…A majority of 75% of fractures occur in males aged between 20 and 30 (Ellis et al, 1985;Moore et al, 1985), and are often caused by physical assault. Other causes of fractures include motor vehicle collisions, falls, and sportsrelated injury (Craig et al, 2008;Kovan, 2008). For all these cases surgical repair proves most effective, with the goal of recovering the anatomical structure prior to the injury and thus restoring normal function.…”
