Learn about the 2017 classification of periodontal and peri-implant diseases, stages of periodontitis, systemic disease manifestations, and other relevant conditions. Understand mucogingival deformities, traumatic occlusal forces, prosthesis factors, and peri-implant issues. Compare the 2017 and 1999 classification systems.

Chapter 4Classification of Periodontal and Peri-Implant Diseases and Conditions Section 2 The 2017 Classification of Periodontal and Peri-Implant Diseases and Conditions
Periodontal Health, Gingivitis, Gingival Diseases/Conditions
Necrotizing Periodontal Diseases • Necrotizing gingivitis • Necrotizing periodontitis • Necrotizing stomatitis
Periodontitis as Manifestation of Systemic Disease • Classification of conditions are based on the primary systemic disease
Periodontitis • Four stages based on severity and complexity of management: • Stage I: Initial periodontitis • Stage II: Moderate periodontitis • Stage III: Severe periodontitis with potential for additional tooth loss • Stage IV: Severe periodontitis with potential for loss of the dentition
Periodontitis (cont.) • Extent and distribution • Grades: • Grade A: Slow rate of disease progression • Grade B: Moderate rate of disease progression • Grade C: Rapid rate of disease progression
Other Periodontal Conditions Other periodontal conditions: • Periodontal abscesses • Endodontic-periodontal lesions
Mucogingival Deformities and Conditions Around the Tooth • Gingival phenotype • Gingival/ soft tissue recession • Lack of gingiva • Decreased vestibular depth • Aberrant frenum/muscle position • Gingival excess • Abnormal color • Condition of exposed root surface
Traumatic Occlusal Forces • Primary occlusal trauma • Secondary occlusal trauma • Orthodontic forces
Prostheses and Tooth-Related Factors • Localized tooth-related factors • Localized dental prostheses-related factors
Comparison of the 2017 and 1999 Classification Systems • Earlier literature will make references to chronic and aggressive periodontitis which is from the older system • Good idea to be aware of the older classification system
