For
protrusive contacts an edge to edge upper and lower anterior teeth contact was observed with the aid of articulating paper.18
Maxilla was found to be more
protrusive in males than females whereas the sagittal position of the mandible was similar between the genders in this study.
pycnostachyum were clearly
protrusive. The epidermis includes a single flattened row, rectangular, round or oval-shaped cells.
Earlier cephalometric researches performed on Saudi population with reasonable contour and standard occlusion revealed that Saudis have extra
protrusive dental and facial distinctiveness in contrast to North Americans and British Caucasian persons.14,15 Al-Jasser16 performed two researches which compares Saudi students and North Americans Caucasians in accordance with Steiner's and Down's analyses.
Similarly, in the above cases, the
protrusive facial profile drastically improved.
DS is accompanied by physical functional problems that are highly specific for the orofacial region.1 These functional problems include speech, swallowing and chewing difficulties, and there also appears to be an increase in facial, skeletal and orthodontic problems.1,2 Among the soft tissue characteristics of oral cavity, there exists relative macroglossia since there is a
protrusive tongue with deep fissures and a smaller oral cavity due to the deformity in the midface.1,3,4
As reported in the literature, the high incidence of such injuries may be due to the
protrusive structure of the maxilla (4,11,13,21,23).
Occlusion was controlled in centric, lateral, and
protrusive movements, and premature contacts were removed (Figure 3).
This is backed by a study made on asymptomatic persons, on whom electromyography was carried out; the results arrived are that to carry out an opening for speech the average amplitude of 11mm, with
protrusive components of 12mm and retrusive ones of 5,7mm, and that deviations and laterality oscillate by 1mm on the average.
After luting, the occlusion was verified to avoid both interferences during excursive (
protrusive and lateral) jaw movements and prematurities at maximum intercuspation.
Among these, the mitogen-activated protein kinase (MAPK) signaling pathway has been widely researched [9,10] and has been confirmed to regulate microtubules and actin filaments; the latter of which can produce pushing (
protrusive) forces or pulling (contractile) forces that are particularly important for whole-cell migration [11-13].
The clinical signs were assessed using the RDC/TMD criteria, including pain on palpation, mandibular range of motion (mm), associated pain (jaw opening pattern, unassisted opening, maximum assisted opening, mandibular excursive, and
protrusive movements), sounds coming from the TMJ, and tenderness induced by muscle and joint palpation.
