AIM To compare the displacement gap of mandible fracture segments treated with different designs of mini-plates under various loading conditions. MATERIALS AND METHODS Fracture in the body of mandible was bridged with 15 different designs and configuration of titanium mini-plates. Bite forces were applied at 3 locations, ipsilateral fractured side, contra lateral side and incisor site. 3D fin...

A collapsible tube surrounded by soft material within a rigid box was proposed as a two-dimensional mechanical model for the pharyngeal airway. This model predicts that changes in the box size (pharyngeal bony enclosure size anatomically defined as cross-sectional area bounded by the inside edge of bony structures such as the mandible, maxilla, and spine, and being perpendicular to the airway) ...

INTRODUCTION Mandible reconstruction is still very challenging for surgeons. Mandible defects could be the consequence of ablative surgery for malignancies, huge jaw cysts, infection and trauma. Segmental resection of the mandible may compromise orofacial function and often lead to patients psychological disorders. Despite very frequent use of microvascular flaps, autogenous bone grafts are sti...

Contact relations between the teeth in the lower and upper jaws in the retruded position and on the nonfunctional side were investigated in two different age groups with mean ages of 15 and 22 years, respectively. The subjects had no complaints of mandibular dysfunction. The relations on the nonfunctional side were registered in four different positions of the mandible. Unilateral tooth contact...

AIMS AND OBJECTIVES Orthodontists generally agree that nonextraction treatment is associated with downward and backward rotation of the mandible and an increase in the lower anterior face height (LAFH). They also agree that extraction line of treatment is associated with upward and forward rotation of the mandible and decrease in the LAFH. The intent of this cephalometric investigation was to e...

Abstract Objectives: It is important to know the exact location and anatomic variety of inferior alveolar nerve canal for different procedures of mandibular surgeries. The aim of the present study was to evaluate inferior mandibular canal’s anatomic position by Cone-beam Computed Tomography (CBCT). Methods: In a cross sectional study, CBCT were taken and assessed from 130 patients (...

The mandible has an important role in appearance and function. The aim of this study was to describe and evaluate surgical navigation-assisted mandibular reconstruction with the fibula flap. Patients recruited into the study had a custom dental splint fabricated to maintain the mandible in a fixed position. Later, the computed tomography (CT) scan, preoperative design, and operation on the mand...

Allometry is an important factor of morphological integration that contributes to the organization of the phenotype and its variation. Variation in the allometric shape of the mandible is particularly important in hominid evolution because the mandible carries important taxonomic traits. Some of these traits are known to covary with size, particularly the retromolar space, symphyseal curvature,...

Aim: It has been hypothesized that the association of pacifier use with reduced risk of sudden infant death is mediated by forward movement of the mandible and tongue that helps open the upper airway. Our aim was to examine whether the mandible is moved forward when an infant is sucking on a pacifier, and if so, whether the mandible remains advanced after the pacifier is removed. Methods: In si...

Abstract The evolution of male-male aggression is interest because at its extreme it can be very energetically costly, leave males vulnerable to preadtors, and give rise weaponry such as exaggerated traits. In grasshoppers (Acrididae), one group stands out exceptionally aggressive, the skyhoppers ( Kosciuscola ) in which bite, kick, mandible flare, wrestle each other for access females or when ...
