From early childhood, Turner syndrome patients have a flattened cranial base, maxillary retrognathism, and short hands. There are, however, no studies that show when these genotype-determined abnormalities occur prenatally. The purpose of the present study was to measure craniofacial profile and hand radiographs of second trimester foetuses with Turner syndrome and compare the results with simi...

In terms of pathophysiology, an anatomically narrow airway is a predisposing factor for obstruction of the upper respiratory tract. The correlation between the nasopharyngeal airway and the craniofacial structures is discussed in this context. Thus a mutual interaction between the pharynx and the mandibular position was demonstrated, whereby the transverse dimension of the nasopharynx was signi...

Background Passive mandibular advancement with functional appliances is commonly used to treat juvenile patients retrognathism. Objective The aim of this study was investigate whether active repetitive training the mandible into an anterior position would result in a shift habitual (HMP). Methods Twenty adult healthy subjects were randomly assigned one two groups: group receiving six supervised...

In this case 7-year-old boy with severe distal bite caused by mandibular retrognathism was treated Fränkel functional regulator type Ic. Aim: The aim of paper to show main skeletal and dental effects I in early treatment bite. Appropriate timing for usage appliance can successfully correct avoid later prolonged orthodontic treatment. Material method: mixed dentition Class II treated. Before cli...

Introduction: The understanding of the craniofacial morphology skeletal Class II malocclusion is a key element in planning orthodontic treatment. aim this study was to describe various skeletal, dentoalveolar, and soft tissue components Nepalese patients. Materials Method: This cross-sectional carried out at Universal College Medical Sciences (UCMS) Department Orthodontics Dentofacial Orthopedi...

Background and Objectives: Split sagittal osteotomy is a common operation that may induce inferior alveolar nerve (IAN) damage, potentially leading to sensory deficit, numbness, and pain. Investigations in Iran to evaluate the adverse effects of sagittal split osteotomy surgery are rare so questions have been raised about the success rate of operatio...

The aim of the present study was to investigate, by means of an extensive cephalometric examination, the alterations which took place in hyoid bone position, head posture, position and morphology of the soft palate, and tongue and sagittal dimensions of the pharyngeal airway after mandibular advancement osteotomy for the correction of mandibular retrognathism. The sample consisted only of adult...

The overall aim of this thesis was to study dentofacial morphology in Turner syndrome (TS) versus controls and the influence hereupon from karyotype. One hundred thirty two TS females (5-66 years of age), from Göteborg, Uppsala and Umeå were participating. Cephalometric analysis, cast model analysis concerning palatal height, dental arch morphology and dental crown width were performed. Eightee...

The flow dynamics of respiratory airflow is the basic factor that influences the ventilation function of the upper airway. This research aimed to investigate the pharyngeal flow field characteristics after Twin Block (TB) treatment in growing patients with Class II(1) and mandibular retrognathia by computation fluid dynamics (CFD) simulation. Cone beam computed tomography (CBCT) scans of patien...
