Looking at the dental arch shown (bilateral posterior missing teeth with anterior teeth present), what is the Kennedy Classification?
Show answer and explanation
Correct answer: A. Class I
Kennedy Class I (A) — bilateral posterior edentulous areas located posterior to the remaining natural teeth. The image shows teeth present anteriorly with missing posterior teeth on BOTH sides — this is the classic Kennedy Class I (bilateral distal extension).
Kennedy Classification:
• Class I: Bilateral edentulous areas posterior to remaining teeth (distal extension, bilateral)
• Class II: Unilateral edentulous area posterior to remaining teeth (distal extension, one side)
• Class III: Unilateral edentulous area with natural teeth anterior AND posterior to the space (bounded saddle)
• Class IV: Single bilateral edentulous area ANTERIOR to remaining teeth (crosses midline — no modification classes)
• The 'Applegate rules' govern classification when multiple edentulous areas exist.
