Advances in Dental Implants: A Review of In Vitro and In Vivo Testing with Nanoparticle Coatings

Abstract

Since tooth loss is a common problem in humans and is widespread worldwide, dental implants are an effective and optimal alternative to solve this problem. Thus, it is necessary to develop implants with improved surfaces that favor the osseointegration of the implant into the surrounding tissues and promote cell adhesion and proliferation while also preventing and inhibiting peri-implant infections that can lead to implant failure. In this regard, this review aims to provide new insights into nanotechnology and the use of nanoparticles in creating new coatings, the new trends for enhancing dental implant surfaces, and the current technologies used for this purpose. Although in vitro and in vivo tests attest to the possible use of the nanomaterials described in this review, further tests are needed to establish the optimal concentrations to be safe for clinical trials.
