Current state-of-the-art and future perspectives of the three main modern implant-dentistry concerns: Aesthetic requirements, mechanical properties, and peri-implantitis prevention.

Abstract

The idea of permanent tooth replacement goes back to the year 2000 BC at least, when carved bamboo pegs were used to replace missing teeth in ancient China. The phenomenon of osseointegration, however, was not verified until the mid-1960s, when Branemark discovered that titanium could integrate to bone. Since then, the osseointegration capacity of implants has been profoundly investigated and implants as such have evolved enormously in all possible aspects, from material selection and processing to specific surface engineering, among many others. This review article, in particular, focuses on dental implants and aims to introduce the main concerns involved in modern dentistry, concentrating especially on the importance of finding an effective way to prevent peri-implantitis. In this sense, strategies such as shifting from metal to ceramic implant components and applying novel antimicrobial antibiotic-free coatings seem to be taking the lead. © 2019 Wiley Periodicals, Inc.
