OBJECTIVE To evaluate the craniofacial asymmetry in adults with neglected congenital muscular torticollis (CMT) by quantitative assessment based on craniofacial three-dimensional computed tomography (3D-CT). METHODS Preoperative craniofacial asymmetry was measured by 3D-CT for 31 CMT subjects ≥18 years of age who visited a tertiary medical center and underwent 3D-CT between January 2009 and D...

There might be gender differences in segmental foot motion considering the gender differences in the foot shape and the prevalence of pathologies [1,2]. The objectives of this study were 1) to obtain reference data of segmental motion of the foot using a multi-segment foot model (MFM) with 15-marker set from healthy adults; 2) to find gender differences in segmental foot motion during gait. One...

With the exploitation of offshore oil and gas gradually moving to deep water, higher temperature differences and pressure differences are applied to the pipeline system, making the global buckling of the pipeline more serious. For unburied deep-water pipelines, the lateral buckling is the major buckling form. The initial imperfections widely exist in the pipeline system due to manufacture defec...

Traumatic injuries to primary teeth are very common. A properly designed fixed space maintainer not only preserves arch length but also reduces the psychological trauma, speech problems and prevents the development of tongue thrusting habits. As, it is difficult while operating in such young patient’s mouth, this article describes a simple technique to quickly fabricate a space maintainer for a...

STATEMENT OF THE PROBLEM Nasal breathing is the major pattern of air intake. Changes in breathing pattern alter the posture of the head, jaws and tongue that could change pressure on the jaw and teeth and affect their growth. PURPOSE This study aimed to investigate the relationship between septal deviations (SD) per se and in combination with concha bullosa (CB) on maxilla; particularly the d...

Background. Human feet have important roles in supporting, moving and balancing the body. The feet must not only support the weight of the body but must also have the elasticity to absorb the burden associated with supporting excessive body weight. Objectives. The purpose of this study was to compare the difference of foot pressure, ground reaction force, and balance ability according to chang...

To many orthodontists, it is clinically relevant to avoid extractions in the treatment of Angle’s Class II Division 2 (Class II/2) malocclusions. The most commonly cited side effects from extraction treatment are a tendency toward flattening of the facial profile and deepening of the bite. The aim of this study was to select a model of cephalometric predictor variables for treatment decision-ma...

BACKGROUND Children with severe airway obstruction tend to have a vertical direction of growth, class II malocclusion, and narrow arches. Adenoidectomy and tonsillectomy were recommended for the promotion of balanced dentition growth in these children.The aim of this study was to determine the effect of adenoidectomy and tonsillectomy on the growth of dental morphology in children with airway o...

The closed section of the inverted arch, formed by surrounding rock, acts as a bearing ring. Combined with upper initial support, it ensures stable support. However, excavating arch can disturb original balance, significantly affecting tunnel’s stability. To determine optimal exposure length and excavation elevation arches at different rock levels, numerical analyses were conducted. These used ...
