What is the Kennedy classification of the partially edentulous mandibular arch?

As per Kennedy’s classification, there are four main types of partially edentulous arches as Class I, Class II, Class III and Class IV. Kennedy’s classification is widely accepted due to its advantages of immediate visualization and recognition of prosthesis support [2,3,10].

What is partially edentulous arch?

CLASS X: A partially edentulous situation in which the remaining teeth are incapable of providing any support. If the teeth are kept to maintain alveolus integrity, the arch must be restored with an OVERDENTURE which is a complete denture supported primarily by the denture foundation area.

What are the classification of partial denture?

 Class I: Bilateral space with no teeth posterior to it.  Class II: Bilateral space with teeth present posterior to one space.  Class III: Bilateral space with teeth present posterior to both spaces.  Class IV: Unilateral space with no teeth posterior to it.

What are the rules Applegate’s governing the classification of partially edentulous arches?

Applegate’s Rules: They are 8 rules to govern the application of the Kennedy system: Rule 1: Classification should follow rather than precede extractions that might alter the original classification. Rule 2: If the third molar is missing and not to be replaced it is not considered in the classification.

What are the classes of partially edentulous arches?

KENNEDY CLASSIFICATION• Kennedy divided all partially edentulous arches into four basic classes. Edentulous areas other than those determining the basic classes were designated as modification spaces.•

What are the different types of RPDs?

There are three types of RPDs or partially edentulous arches based on the tissue(s) which provide support. Support is the resistance to movement of the denture toward the edentulous ridge. RPDs maybe tooth supported, tissue supported, and tooth- tissue supported.

Which is true of the tooth supported RPD?

Support is the resistance to movement of the denture toward the edentulous ridge. RPDs maybe tooth supported, tissue supported, and tooth- tissue supported. This is a simple classification system and very meaningful because the principles of RPD design 2-2 depends, to a great extent, on its supporting tissue(s). The Tooth Supported RPD

When to use a classification system for partial edentulism?

Class IV Loss of posterior support Class IV Advanced wear Guidelines for the Use of the Classification System for Partial Edentulism In those instances when a patient’s diagnostic criteria are mixed between two or more classes, any single criterionof a more complex classplaces the patient into the more complex class
