Stage IV (severe) periodontitis:  diagnosis, treatment, and possibilities for restoring oral functions.

Stage IV periodontitis is the most severe form of periodontal disease.   Patients with stage IV periodontitis, diagnosed using the 2018 classification, share the severity and complexity found in patients with stage III, such as severe attachment loss, inflammation, and deep pockets.  However, those cases also include important anatomical and functional sequelae (tooth flaring and drifting, bite collapse, etc.) and, most important, tooth loss.  The treatment should consist of the traditional "Steps 1-3" of periodontal therapy (Herrera et al. 2022) as in Stage 1-3 periodontitis, but requires additional multidisciplinary interventions to meet the particular demands of this severe stage of the disease.  In these patients, rehabilitation of function, restoration of masticatory comfort and treatment of secondary occlusal trauma, and restoration of the vertical dimension of the occlusion are also necessary and need to be planned a-priori and implemented simultaneously or after steps 1–3 of therapy.  Treatment of the functional sequelae may include control of tooth mobility, orthodontic therapy, and tooth/implant-supported rehabilitations. 

What is the sequence of treatment for such cases?  What is the best timing for orthodontic treatment?  What is the preferred prosthetic treatment?  During the presentation, we will discuss optional treatment strategies for Stage IV clinical cases, based on the evidence derived from the EFP systematic reviews and the EFP's recent S3-level clinical practice guideline.
