Who developed the most widely accepted classification system for partially edentulous arches?

Partially edentulous arches have been classified according to several methods. The Kennedy classification proposed by Dr. E. Kennedy is the most widely accepted and used classification method due to its simplicity and ease of application, with nearly 65,000 possible combinations of partially edentulous arches.

What are the types of RPD?

There are 3 types of removable partial dentures: acrylic tissue-supported dentures, dentures with cast metal frameworks en dentures with cast metal frameworks and (semi)precision attachments.

What is cross arch stabilization?

The denture design method most commonly used is cross arch stabilization which involves creating a retainer on the side opposite the defect via a bar in order to stabilize the denture and protect the retaining teeth.

What is Kennedy classification?

A system developed by Dr. Edward Kennedy for classification of edentulous jaw conditions and partial dentures, based on the distribution of edentulous spaces. Class I is bilateral free-end saddles. Class II is a unilateral free-end saddle. Class III is a unilateral single bounded saddle.

What is a Class 5 cavity?

Class V cavities

Class V lesions occur on the cervical 1/3 of the labial surfaces of incisors and canines; and on the buccal and lingual surfaces of premolars and molars. They take place under two case scenarios; through the formation of caries or through the loss of tooth substance due to abrasion/erosion.

What are the disadvantages of partial dentures?

The Cons of Partial Dentures

Partial dentures can increase the buildup of plaque around the abutment teeth leading to tooth decay and gum disease. The abutment teeth may experience trauma along with the gums due to the pressure and movement of the partial. The loss of an abutment tooth may require a new partial.

What are the problems with partial dentures?

The three most common problems that I see with partials are broken partials, partials that no longer fit due to gum shrinking, and partials that no longer fit due to tooth loss. Even though partials are made from strong materials, through enough wear and tear in the mouth or an accidental drop, they can break.
