This course will examine the concepts of staging and grading to classify each patient by complexity of case management, likelihood of less predictable response. The updated American Academy of Periodontology (AAP) classification system represents a multi-dimensional staging and grading framework for periodontitis and implant disease status. The systemic connection as it relates to the grading portion of the classification system will be examined and its relationship to oral health/periodontal disease. Diagnosing, treatment planning and executing appropriate and necessary periodontal therapies will be reviewed utilizing case presentations.
