Which of the following is a subcategory of Peri-Implant Diseases in the 2017 classification?

Peri-implant mucositis is indeed a recognized subcategory of peri-implant diseases as defined in the 2017 classification system. It refers to a localized inflammatory condition affecting the soft tissues surrounding a dental implant, without bone loss. Identifying and treating mucositis is crucial, as it can evolve into more severe conditions, such as peri-implantitis, if left unmanaged.

The classification is aimed at standardizing the diagnosis and management of complications related to dental implants, facilitating communication among dental professionals and guiding treatment plans. Understanding peri-implant mucositis allows practitioners to address inflammation early, improving the long-term success of implants.

The other terms listed, while related to implant dentistry, do not fit as subcategories of peri-implant diseases within this specific classification framework. For instance, peri-implant health denotes a state where the implant and surrounding tissues are healthy, which is not classified as a disease but rather a desirable condition. Peri-implant complications refer to a broader category that does not specify a particular disease state, while peri-implant hyperplasia isn't recognized as a standard term within peri-implant disease classifications. Thus, peri-implant mucositis is the only correct answer regarding established subcategories in the classification.
