Peri-implant and periodontal tissues: a review of differences and similarities

Abstract

The health and vitality of an osseointegrated implant depends on the surrounding supporting tissues, which not only anchor the implant to the bone but also have the important function of providing a protective seal. The aim of this article is to provide a basic understanding of differences and similarities between the periodontal and peri-implant tissues at the histologic, clinical, and immunologic levels; it is essential to know these differences and similarities during the clinical handling of these similar-looking tissues. The comparative features are of clinical relevance because it is critical to understand the behavior of the soft tissue found around the tooth and implant. This knowledge is vital from the preliminary stage of treatment planning through prosthetic rehabilitation.
