With a very large number of endosseous dental implants placed by generalists and specialists, complications are to be expected. Among them are problems with the soft tissue interface and the hard tissue attachment. Peri-implant mucositis and peri-implantitis are not uncommon, but their prevalence and impact may be reduced with diagnosis and appropriate management, as can the likelihood of progression from mucositis to peri-implantitis. Successful implant dentistry does not end with integration and restoration, and both patient and professionally administered modalities are important for long-term implant maintenance.
