In an effort to better understand the mechanics of ship-whale collision and to reduce the associated mortality of the critically endangered North Atlantic right whale, a comprehensive biomechanical study has been conducted by the Woods Hole Oceanographic Institution and the University of New Hampshire. The goal of the study is to develop a numerical modeling tool to predict the forces and stres...

Abstract The first step of implanting teeth is to drill a hole in the jaw bone. Excessive temperature produced during drilling is one of the destructive factors for bony tissue. If the temperature generation during surgical drilling exceeds the critical temperature, it could lead to osteonecrosis. This research intends to study drilling parameters such as drilling speed, feed rate, cooling con...

Marmots have a prominent role in the study of mammalian social evolution, but only recently has their systematics received the attention it deserves if sociobiological studies are to be placed in a phylogenetic context. Sciurid morphology can be used as model to test the congruence between morphological change and phylogeny because sciurid skeletal characters are considered to be inclined to co...

OBJECTIVES/HYPOTHESIS To evaluate the use of computer-assisted design and rapid prototype modeling to improve the speed and accuracy of mandibular reconstruction. STUDY DESIGN Case-control study. METHODS Between 2005 and 2011, 38 subjects underwent fibula free flap mandibular reconstruction using computer-assisted design and rapid prototype modeling. Titanium plates were prebent using the m...

This study was carried out to determine the morphometric and volumetric features of mandible in Van cats by using computed tomography (CT) a three-dimensional (3D) software program. The also aimed at presenting biometrical differences these mea- surements between genders. A total 16 adult (8 males, 8 females) were used study. anesthetized ketamine-xylazine combination. They then scanned CT unde...

SUMMARY The reconstruction of mandibular defects has always been of great concern, and it still represents a challenge for head-and-neck reconstructive surgeons. The mandible plays a major role in mastication, articulation, swallowing, respiration, and facial contour. Thus, when undertaking mandibular reconstruction, restoration of both function and cosmetics should be considered as the measure...

accurately localizing the mental foramen and mandibular canal is important when administering local anesthesia and performing surgery; therefore, knowing the normal range of the possible locations is essential. our purpose was to assess the location of the mental foramen and mandibular canal in an iranian population using panoramic radiography.standard panoramic radiographies were performed. th...
