Introduction. Maxillofacial fissures are the most common form of congenital malformations face and maxillofacial region. These forms may vary from simple shapes to particularly non-specific forms. The cleft lip palate characterized by anatomical functional disorders. In unilateral total splits, disorders bone deformities. upper jaw is divided into two segments fissure that passes on lip, alveol...

Horizontal intracortical connections may form one substrate for representational plasticity in somatosensory cortex. Electrophysiological mapping demonstrated the finer details of the representations of the hand, lower jaw, neck, and face in area 3b of normal macaque monkeys. Injections of two fluorescent tracers then defined the extent to which horizontal connections crossed from the face into...

Background: The aim of this study was to investigate the effects orthognathic surgery on periodontium in 3rd and 6th months after operation. Methods: In a total 10 patients (7 females, 3 males, mean age 23.2 ± 4.83), full mouth clinical periodontal measurements as plaque index (PI), gingival (GI), probing depth (PD), bleeding (BOP), attachment level (CAL), mobility (M) were performed before sur...

Caecilians (Lissamphibia: Gymnophiona) are unique among vertebrates in having two sets of jaw-closing muscles, one on either side of the jaw joint. Using data from high-resolution X-ray radiation computed tomography scans, we modelled the effect of these two muscle groups (mm. levatores mandibulae and m. interhyoideus posterior) on bite force over a range of gape angles, employing a simplified ...

BACKGROUND Dolphin® visual treatment objective (VTO) prediction software is routinely utilized by orthodontists during the treatment planning of orthognathic cases to help predict post-surgical soft tissue changes. Although surgical soft tissue prediction is considered to be a vital tool, its accuracy is not well understood in tow-jaw surgical procedures. The objective of this study was to quan...

A facial scanner and three-dimensional computed tomography (CT) were used to evaluate the change in lip asymmetry before after two-jaw surgery for 22 patients with (menton deviation > 3 mm). We labrale superius (Ls), deviated/non-deviated-side cheilions (Ch-D/Ch-ND), inferius (Li) construct upper lower planes asymmetry. correlation analysis was performed determine factors related vertical (Δ...

This study was performed to evaluate the relationship between condylar height reduction and changes in surface computed tomography (CT) values jaw deformity patients following orthognathic surgery. Mandibular advancement by sagittal split ramus osteotomy (SSRO) with Le Fort I class II patients, mandibular setback SSRO III patients. The maximum CT (pixel values) at five points on height, square,...

Depending on the affected craniofacial structures, facial asymmetry can be divided into skeletal, dental and functional asymetry. Some asymmetrical disorders can, besides being an aesthetic problem, negatively affect mouth-teeth jaw functions. For exact localization of structures to determine cause extent asymmetry, it is helpful use other diagnostic aids such as study models, face bow transfer...

In previous in vitro experiments using an Instron instrument, each test food was found to have characteristic textural properties. In vivo experiments were now made (1) to determine the degree to which variations in the vertical jaw movements during the crushing phase of mastication can be explained by the inherent properties of the foodstuff being chewed, and (2) to establish the degree to whi...
