Extensive orthodontically induced dental resorption: What to do?

Abstract

If essential care is thorough, teeth with extensive orthodontically induced dental resorption can have the same endurance as normal teeth. These teeth are subjected to the same disturbances as normal ones, such as dental trauma, dental caries and periodontal disease, all of which are independent of severe dental resorption. Orthodontic retreatments of teeth presenting with extensive orthodontically induced dental resorption must take into consideration that these roots are shorter in length, therefore, they are more prone to root resorption. Conventional movements are not viable in severe resorption, but Orthodontics offer some alternatives, such as; 1) movement of multiple teeth, providing better distribution of force; 2) use of lesser forces along with bodily movements, as opposed to rotation; 3) anchorage using miniplates, which provide more diffuse and equally distributed force and movements upon teeth and bone. Extensive orthodontically induced dental resorption are not an indication for endodontic treatment. These teeth also should not be replaced by osseointegrated dental implants, but they must receive special care, as they must remain in the dental arch indefinitely.

Efectos de los tratamientos de ortodoncia en los tejidos periodontales

“…Melsen et al 10 encontraron de 1 a 3 mm de reabsorción radicular en los incisivos tratados, mientras que Corrente et al 10 no reportaron reabsorción de dientes instruidos por ortodoncia. Estudios también demuestran que en dientes unirradiculares el tratamiento de ortodoncia en pacientes.…”

“…Runzhi Guo et al 10 en su estudio en el que muestra los cambios óseos de los dientes anteriores maxilares y mandibulares durante el tratamiento de ortodoncia con extracciones, mostraron a nivel de los incisivos superiores una perdida ósea vertical en vestibular de (0,36 mm) y en la cara lingual de (0,94 mm) con una reducción del grosor del hueso en la cara lingual siendo más significativa a nivel cervical (0,57 mm). En aquellos pacientes en los que no se realizó exodoncias en la cara vestibular la perdida ósea fue de (0,97 mm) y la cara lingual (0,86 mm).…”

Distributed System for Wheel and Rail Detection Based on ZeroMQ

“…The latter consists of processes, databases, tables, files, and processes. These resources are allocated to each physical node, and the communication between each node is mainly through the network, so that a unified computer system can be created [14][15].…”

Time Synchronization Method of Distributed System Considering Local Area Network

“…When the master clock receives the delay request message, it uses the timestamp to accurately record the time when the message arrives at the master clock. Next, the master clock sends a delayed response message, which has the same function as the follower message [18].…”
