To ensure satisfaction among Prosthdontists, a system of classification was introduced by the American college of Prosthodontics (ACP).6 Recently this classification system was re-named as Prosthodontic diagnostic index (PDI).

To ensure satisfaction among Prosthdontists, a system of classification was introduced by the American college of Prosthodontics (ACP).6 Recently this classification system was renamed as Prosthodontic diagnostic index (PDI). ACP pDI classification is based on. The American College of Prosthodontists has developed a classification system for complete edentulism that can be used to guide overall treatment planning and management of patients with complete dentures. Classification of Implant Patients The prosthodontic-based implant patient classifica- tion system is initially divided into two stages (Table 1). All the forms must be approved (and swiped) by the supervising instructor. the Classification of Complete Edentulism (Prosthodontic Diagnostic Index - PDI). If the patient has an existing complete denture, they are evaluated for their retention, stability, esthetics, vertical dimension of occlusion, centric occlusion, and patient satisfaction. Most relevant lists of abbreviations for PDI (Prosthodontic Diagnostic Index) The new edition of this well established and highly regarded textbook has been completely revised and updated to reflect the latest developments in the field of tooth loss and denture provision. The absence of classification and referral has always been an obstacle in accurate system of treatment planning. ü Does not look at what the treatment will be but at the condition of Pattient ü Indicates increasing levels of diagnos)c and treatment complexity ü May suggest the point of referral. When a dental student, new to the clinic experience, is assigned a difficult edentulous patient (Prosthodontic Diagnostic Index = 4; prosthodontic classification index which helps determine degree of difficulty 2,3), that student might be justified in a negative bias toward removable prosthodontics. Stage I covers prosthetic design and implant location for both edentulous and partially edentulous patients. A significant number of edentulous patients with complex treatment needs are seen in private practice and faculties of dentistry. The condylar diagnostic settings were adjusted with the aid of laterotrusive and protrusive interocclusal records. According to the Prosthodontic Diagnostic Index (PDI) Partial Edentulism Classification system, the patient was characterized as class III. The absence of classification and referral has always been an obstacle in accurate system of treatment planning. The aim of treatment was to restore esthetics and improve masticatory function. A comprehensive examination was carried out with the aid of the Prosthodontic Diagnostic Index (PDI) Complete Edentulism Checklist, based on the PDI classification system by the American College of Prosthodontists. Twelve patients were classified as PDI Class I, which represented favorable diagnostic criteria with a good prognosis. She was classified as an American College of Prosthodontists Prosthodontic Diagnostic Index (ACP PDI) class III patient. PLAY. Categories. This stage of the classification system has the greatest impact on patient acceptance. Thus, the document indicates diagnosis and treatment planning as a function of the complexity of the patient’s Therefore, the Classiﬁcations (Completely Dentate, Partially Edentulous, and Completely Edentulous) have been incorporated into each appropriate section.
