Classfication of partially edentulous arches

1. What is the primary purpose of classifying partially edentulous arches?

• • (a) To predict the success rate of dental implants.

• (b) To facilitate treatment decisions based on complexity

• (c) To estimate the cost of treatment.

• (d) To determine the best type of denture adhesive

Which classification system is most widely accepted for partially edentulous arches?

• (a) The Cummer classification

• (b) The Bailyn classification

• (c) The Kennedy classification

• (d) The Skinner classification

According to the Kennedy classification, a patient with missing teeth on both sides of the lower jaw, posterior to the remaining teeth, would be classified as:

• (a) Class II

• (b) Class III

• (c) Class IV

• (d) Class I

A single, bilateral edentulous area located anterior to the remaining natural teeth characterises which Kennedy classification?

• (a) Class I.

• (b) Class II

• (c) Class III

• (d) Class IV

What is a modification space in the Kennedy classification system?

• (a) An edentulous area that determines the primary classification

• (b) An edentulous area in addition to those determining the primary classification.

• (c) A space created by the loss of a third molar.

Which of the following statements about Kennedy Class IV arches is TRUE?

• (a) They can have multiple modification spaces

• (b) They always involve the loss of anterior teeth

• (c) They cannot have modification spaces

• (d) They are the most common type of partially edentulous arch

According to Applegate's rules, when should the classification of a partially edentulous arch be determined?

• (a) After any planned extractions

• (b) Before any planned extractions

• (c) During the fabrication of the denture

• (d) After the placement of any dental implants

If a third molar is present but is not to be used as an abutment, how is it considered in the Kennedy classification?

Which factor determines the primary classification in the Kennedy system?

• (a) The number of missing teeth

• (b) The location of the most posterior edentulous area

• (c) The condition of the abutment teeth

• (d) The presence or absence of third molars

What is the main advantage of the Kennedy classification system?

• (a) Its complexity allows for detailed descriptions of various cases

• (b) It facilitates immediate visualisation of the partially edentulous arch.

• (c) It accurately predicts the longevity of partial dentures

• (d) It eliminates the need for other diagnostic tools
