Abstract(s)
A alergia a metais é uma reação comum, contudo pode ser difícil de diagnosticar, desde a falha do implante até à dermatite de contacto sistémica (Chen et al., 2018).
No âmbito da Medicina Dentária, são utilizados diversos metais, sendo as fontes com maior frequência de contacto contínuo a metais: os implantes, as restaurações dentárias, as próteses metálicas e os arcos de ortodontia (Vaserman, 2019).
Com o aparecimento da osteointegração, os implantes dentários começaram a ser utilizados de forma disseminada, com o principal objetivo de diminuir as consequências do edentulismo, seja ele total ou parcial (Galan Jr. et al., 2013).
As superfícies modificadas dos implantes podem ser consideradas uma estratégia para aumentar as taxas de sucesso, contudo em algumas situações, interferem na regeneração óssea (Ribeiro et al., 2009). Quando submetidos ao jateamento com óxido de alumínio, demonstraram resíduos provenientes da técnica de tratamento da superfície, contaminando-a, prejudicando a osteointegração (Misch, 1999) e, possibilitando manifestações sistémicas causadas pelas partículas de óxido de alumínio (Authier et al., 2001; Guis et al., 2002). Tendo em conta que existem indivíduos com hipersensibilidade ao alumínio, que poderão ou não ter conhecimento da mesma e que, muitos implantes dentários apresentam superfícies modificadas, através do jateamento com óxido de alumínio, esta revisão bibliográfica apresenta como objetivo, avaliar a correlação entre o insucesso do implante dentário, em indivíduos com hipersensibilidade ao alumínio, com o jateamento das superfícies dos implantes com óxido de alumínio.
Allergy to metals is a common reaction, however it can be difficult to diagnose, from implant failure to systemic contact dermatitis (Chen et al., 2018). In the field of Dentistry, several metals are used, being the sources with the highest frequency of continuous contact with metals: implants, dental restorations, metallic prostheses and orthodontic arches (Vaserman, 2019). With the appearance of osteointegration, dental implants defined a being used in a widespread manner, with the main objective of reducing the consequences of edentulism, be it total or partial (Galan Jr. et al., 2013). The modified surfaces of the implants can be considered a strategy to increase success rates, however, in some situations, they interfere with bone regeneration (Ribeiro et al., 2009). When discovered when blasting with aluminum oxide, they demonstrated residues from the surface treatment technique, contaminating it, impairing osteointegration (Misch, 1999) and, allowing systemic manifestations caused by aluminum oxide particles (Authier et al., 2001; Guis et al., 2002). Bearing in mind that there are hypersensitivity to aluminum, that you may or not be aware of, and that many dental implants have modified surfaces, through blasting with Al2O3, this bibliographic review aims to evaluate the correlation between the dental implant, in compliance with hypersensitivity to aluminum, with the blasting of implant surfaces with aluminum oxide.
