Classification System for Complete Edentulism

Abstract

The American College of Prosthodontists has developed a classification system for complete edentulism based on diagnostic findings. These guidelines may help practitioners determine appropriate treatments for their patients. Four categories are defined, ranging from Class I to Class IV, with Class I representing an uncomplicated clinical situation and a Class IV patient representing the most complex and higher-risk situation. Each class is differentiated by specific diagnostic criteria. This system is designed for use by dental professionals who are involved in the diagnosis of patients requiring treatment for complete edentulism. Potential benefits of the system include: 1) better patient care, 2) improved professional communication, 3) more appropriate insurance reimbursement, 4) a better screening tool to assist dental school admission clinics, and 5) standardized criteria for outcomes assessment.

Comparison of treatment outcomes in digital and conventional complete removable dental prosthesis fabrications in a predoctoral setting

“…This appointment for initial examination and informed consent was not considered part of the fabrication process. The Prosthodontic Diagnostic Index (PDI) 13 for participants in the study was Type I (2 participants) or II (13 participants). Two sets of maxillary and mandibular CRDP were fabricated for each participant by a third-year or fourth-year predoctoral dental student at LLUSD.…”

Single dental implant retained mandibular complete dentures – influence of the loading protocol: study protocol for a randomized controlled trial

“…It was estimated that 230 people assessed for eligibility would result in 180 people being allocated to the trial (an exclusion rate of 21.7%). So far, 19.1% of patients who have undergone screening have had to be excluded due to insufficient bone according to McGarry [14]. The residual bone height seems to be a major factor when considering edentulous patients for implant therapy.…”

“…[14]) as the lowest vertical height of the mandible and the vertical bone height in the midline of the mandible is at least 13 mm.…”

“…Stratification is according to the patient’s residual bone height (Class II or III according to McGarry et al . [14]) and the study center.…”

Effect of impression valve system on adhesion force of impression materials to edentulous maxillary jaw: a preliminary clinical study

“…Patients were classified according to residual ridge morphology using the Prosthodontic Diagnostic Index. [11] Dimensional measurements were made on primary cast models in three axes using a digital caliper (Mitutoyo, Japan), as shown in Figure 1. Patients who had type C maxilla (loss of anterior labial vestibule, prominent midline suture, and hyperplastic and mobile anterior ridge) were also excluded from the study.…”
