Como consecuencia de la pérdida de dientes, el hueso alveolar carente de ligamento periodontal recibe las fuerzas que se transmiten al hueso como tensiones, provocando resorción ósea. Se han encontrado cambios traducidos como pérdida ósea en la zona de la cresta alveolar (cerca de dos milímetros), los cuales han sido reportados en el primer año de carga del implante. Estudios sugieren que el tipo de conexión del implante influye en la disminución de tensiones a nivel cervical del implante y, por ende, del hueso. Actualmente no hay muchas investigaciones que comparen la distribución de tensiones en conexiones hexágono interno, externo, y cono Morse. El propósito de este estudio fue analizar las tensiones compresivas a nivel cervical del hueso, implante y componentes en conexiones tipo: hexágono externo, interno y cono Morse, en elementos finitos (MEF). Los tres modelos en ele...

The laser was integrated into the medical sciences in the 70s and is constantly evolving. In the dental market we find high power lasers, such as the Argon, Diode, Nd: YAG, Er, Cr: YSGG, Er: YAG and CO2 lasers. The most highlighting applications of the diode laser are in soft tissues and the Erbium laser are for hard tissues. Among the advantages of high-power lasers is to accelerate healing and the expression of collagens, disinfection of root canals in pulpectomies, and a decrease in dental permeability. In Pediatric dentistry, we must highlight the cavity preparation which generates the reduction in working time and an increase in patient collaboration due to the reduction/elimination of pain in procedures; such as avoiding the application of anesthesia. The points to be evaluated for the health professional is the cost/benefit and the necessary training to carry out the procedures wi...

Aim: to identify and systematize information of greater relevance in the use of Low Power Lasers (LLLT) in various pediatric dentistry treatments. Methodology: Electronic databases (Medline, Scielo, Scopus, Pubmed, Elsevier and other non-indexed citations) were reviewed, from January 2014 to December 2020. Papers written in English, Portuguese and Spanish, full text available using the keywords: Low power laser, pediatric dentistry laser and photobiomodulation. A total of 65 articles were obtained which were analyzed and selected by a master expert in laser therapy, 46 articles were accepted. Results: The application of the low power laser constitutes a tool for the diagnosis of dental caries. In addition, it allows the resolution of signs and symptoms in oral pathologies. In pulp therapies, success rates greater than 95% are shown. Photobiomodulation in pediatric patients is effective a...

Propósito: analizar y comparar las tensiones en elementos finitos de una nueva propuesta conexión triangular cónica en implantes, con conexiones hexagonales y cónicas. Materiales y métodos: se utilizó el programa solidworks 2017 ® para el análisis en elementos finitos, se consideró una corona de premolar sobre implantes(3.8x12mm) con conexión hexágono externo, interno, cono morse, cónica y la nueva propuesta cónico triangular. Se aplicaron fuerzas de 150N, 250N y 350N en la premolar. Los implantes fueron analizados utilizando el criterio de tensión de von Mises. Resultados: A nivel del implante, pilar y corona la máxima tensión compresiva se encontró en la conexión hexágono externo. A nivel del pilar con fuerzas de 350N la menor tensión se obtuvo en la nueva propuesta y la cónica(10Mpa). Conclusiones: en los 5 diseños la máxima tensión se concentra a nivel del cue...
