• The previous (1999) classification of periodontal diseases did not include peri-implant diseases and conditions. • The 2017 World Workshop presented case definitions and considered the characteristics of peri-implant health, peri-implant mucositis, and peri-implantitis. • Bleeding on probing (BoP) is used to distinguish between healthy and inflamed peri-implant mucosa. • Bone loss is used to differentiate between peri-implant mucositis and peri-implantitis. • The progression of peri-implantitis is faster than that observed in periodontitis and occurs in a non-linear and accelerating pattern.
