Currently, there is a wide use of fiberglass post. However, they have the disadvantage that their shape can not be changed and are inadequate for cases of teeth with extensive coronal destruction and wide root canals. This case report describes the use of a fiberglass post and core manufactured with a CAD / CAM system to restore a lower premolar tooth treated endodontically. This CAD / CAM fiberglass post adapts better to the root canal than a prefabricated post, without the need to use composite resin for the stump and reduces the thickness of the cement layer.

Securing access to quality healthcare services, particularly for essential screening tests like mammograms, presents a significant challenge in developing nations. Women often encounter extensive waiting periods, sometimes extending for several months, to undergo a mammogram. This crucial test plays a pivotal role in the early detection of breast cancer, where timely diagnosis is crucial for effective treatment and enhanced survival prospects. Delays in obtaining a diagnosis can significantly impact the health of patients and their well-being, underscoring the importance of early detection. Compounding these challenges is the scarcity of resources and healthcare professionals, which hinders swift and efficient access to preventive care. Such constraints underscore the pressing need for improvements in the interpretation of radiological studies and a reduction in the workload of imaging s...

Cleidocranial dysplasia (CCD), also known as Marie-Sainton syndrome, is a rare disorder of autosomal dominant type that presents specific characteristics at the skeletal and dental level. The diagnosis of CCD is based on clinical and radiographic findings. Panoramic, cephalometric, and anterior poster radiographs have been used for its diagnosis in dentistry. However, these radiological techniques have limitations, and advances in technology with new imaging studies such as magnetic resonance imaging (MRI) and ultrasound have emerged, contributing to the diagnosis of CCD. Therefore, the aim of this review was to identify and describe current imaging studies that contribute to both the diagnosis and adequate and efficient treatment planning of CCD and describe the clinical and radiographic characteristics of patients with this syndrome.

Monostotic fibrous dysplasia is a benign asymptomatic lesion that affects only one bone, which is replaced by amorphous connective tissue. Clinically there is an increase in the volume of the affected area, which is observed by imaging as a radiopaque area with diffuse non-corticalized limits capable of expanding to neighboring structures, and it is histologically evidenced as “resembling Chinese characters”. The lesion is seen as a radiopaque image with diffuse borders in conventional or digital radiography, while cone beam computed tomography identifies the exact location and extension of an isodense, mixed or hyperdense image of non-corticalized edges. Magnetic resonance imaging is also used when the lesion involves soft tissues or nerves, and bone scintigraphy is performed in order to systemically observe bone quality. The objective of this article was to describe the new technol...

"La pieza es blanca, casi transparente, como un pequeño bloque de hielo. No mide más de 30 centímetros, tiene un diseño escalonado y está hecha de plástico biodegradable. El profesor Edwin Motte la muestra con orgullo, mientras señala una de las impresoras 3D en la que fue creada. Durante un mes, en el Centro de Innovación Tecnológica de la Universidad de Lima, no hubo tregua. Se trabajó mañana, tarde y noche —e incluso feriados— para imprimir 188 piezas similares para dar vida a la gran huaca que hoy se exhibe en el pabellón peruano de la Bienal de Venecia, uno de los elementos centrales de la exposición En reserva, desarrollada bajo la curaduría de la arquitecta Marianela Castro de la Borda, Janeth Boza y Javier Lizarzaburu".

Fixed prosthodontics is performed in different materials to replace absent dental structures, which can be totally metallic or metallic coated with ceramic, being generally widely used. At present, we have proposals for fixed prostheses with better aesthetic results, such as metal-free prostheses, which allow the professional to reproduce better and in more detail the dental anatomy and in this case also the gingival character. Materials such as zirconia are available that have properties such as biocompatibility, low thermal conductivity, resistance to corrosion, naturalness and aesthetics. In addition, new technological methods are available with which very satisfactory results can be achieved, such as the use of CAD-CAM technology. The present clinical case is focused on the replacement of dental organs and soft tissue, for the rehabilitation of the anterior sector, with materials wit...

Por el distrito de Manuel Antonio Mesones Muro de la provincia de Ferreñafe, en la región Lambayeque, transita el Canal Taymi, considerada la obra de irrigación más importante de la costa norte del Perú, en la actualidad ha sido canalizado en su totalidad. En el referido distrito se encuentra ubicado el “Parque de las Aguas”, el único de la región. El elevado costo y los escasos ingresos del municipio no permiten un funcionamiento continuo de este atractivo el cual en los últimos tiempos se ha visto reducido su funcionamiento a los fines de semana y en la actualidad a una vez al mes. La presente investigación plantea el diseño de la rueda hidráulica de Poncelet de corriente libre para aprovechar el caudal del Canal Taymi y transformarla en energía mecánica, y poder transmitirla esta hacia el generador y así convertirla en energía eléctrica. Para posteriormente aliment...

Abstract—Stroke is the third cause of all disabilities for people over 25 years old. Indeed, the percentage of people who suffer from hemiplegia after stroke is higher than 75%. Patients with hemiplegia have considerable difficulty performing activities of daily living, such as feeding or grasping objects. Assistive devices for stroke patients have been developing since a very long time ago; however, some of them are not well accepted by patients because they are not comfortable, wearable, portable, lightweight and useful. This research presents the first version of the design of dynamic orthosis to aid post-stroke patients with hemiplegia to grasp cylindrical and spherical objects. The proposed orthosis was designed by using a cyclic design methodology called Iterative Design which is used for continuous product improvement; moreover, this paper presents a detailed description of the ...

Computer-aided design and computer-aided manufacturing (CAD-CAM) has been applied in dentistry for the preparation and analysis of various dental treatments. It starts with capturing images through intraoral scanners, having different types of software and image export systems and technology. The advantages of this digital workflow are the following: better adjustment, shorter clinical time, and speed in dental treatments, in addition to providing greater practicality for dental surgeons. The accuracy he provide is clinically acceptable in comparison with conventional methods, so there is sufficient evidence for their validity; however, it should be taken into account that several factors can alter the result, such as the operator's experience, the type of scanner, the type of software, the software update, the scanning principle of the scanner, the environment, the scanning sequence, an...
