The Kennedy Classification is used to classify partially edentulous arches. A maxillary arch missing teeth 1, 2, 3, 4, 5 and 12, 13, 14, 15 (with tooth 16 present) is BEST classified as:
Show answer and explanation
Correct answer: B. Kennedy Class II (unilateral)
Kennedy Class II describes a unilateral posterior edentulous area. In this scenario, teeth are missing only in the posterior right quadrant (1–5) and posterior left quadrant (12–15), with tooth 16 present. Depending on the specific arrangement, if there is a unilateral posterior missing area, it is Class II. With bilateral posterior missing areas (both sides behind remaining teeth), it would be Class I. Confirm the most posterior remaining tooth determines the classification. Here: Class II unilateral is described in the source.
- A. ❌ Kennedy Class IV is a single bilateral anterior edentulous area crossing the midline.
- B. ✅ CORRECT – Kennedy Class II is unilateral posterior edentulous.
- C. ❌ Kennedy Class I is bilateral posterior edentulous (both posterior quadrants missing — no posterior teeth on either side).
- D. ❌ Kennedy Class III is a unilateral posterior edentulous area BOUNDED by teeth on both sides (a tooth-supported span).
