1 de may. de 2024 · This review article focuses on the biomechanics of conventional rapid palatal expansion (RPE) and miniscrew-assisted rapid palatal expansion appliances (MARPE). Three main things play an important role in the type of movements that follow rapid maxillary expansion: 1) Center of resistance and anatomy of maxilla, 2) Appliance system ...
15 de may. de 2024 · Abstract. Background. Although orthodontic miniscrews were developed to provide reliable anchorage against orthodontic traction forces, they have pervasive low stability problems. Cutting flute geometry of the screw is considered to be a key factor; however, it has not been fully investigated.
Hace 5 días · Basilar fractures of the skull, also known as base of skull or skull base fractures , are a common form of skull fracture, particularly in the setting of severe traumatic head injury, and involve the base of the skull. They may occur in isolation or often in continuity with skull vault (calvarial) fractures or facial fractures. Epidemiology.
Hace 3 días · The clinical finite element analysis (FEA) application in maxillofacial surgery for mandibular fracture is limited due to the lack of a validated FEA model. Therefore, this study aims to develop a ...
Hace 6 días · The use of miniscrews in the buccal site, although it has limitations due to the presence of the roots of the dental elements, is, in fact, characterized by greater convenience in their insertion and has biomechanical advantages in preventing mesial rotation of molars during the distalization procedure.
Hace 2 días · Transulnar basal coronoid fractures of the elbow are complex injuries in which there is a transulnar fracture dislocation of the elbow, and the coronoid is fractured and not attached to either the olecranon fragment or the metaphyseal segment. These fractures are difficult to manage and can lead to poor outcomes if not adequately addressed. This technical note aims to introduce an approach to ...
Hace 2 días · Abstract. This study aims to delineate the biomechanical responses in both soft and hard tissues, alongside the interactions within the surrounding bone of a human skull subjected to clinical loadings generated by a miniscrew-assisted rapid palatal expansion (MARPE) device. Cone-beam computed tomography (CBCT) scans of a 20-year-old female skull were segmented. The skull bones were ...
