The direction of resorption of the maxillary ridge is:: (A) Downwards and buccally, (B) Upwards and lingually, (C) Downwards and lingually, (D) Upwards and buccally
Answer is B. The maxilla resorbs in a superioposterior direction, and the mandible resorbs in an inferioanterior direction.

This will lead to confinement of maxillary arch within the mandibular arch in longstanding edentulous situations, giving a pseudo-class III ridge relationship.
