- aClass II, immediately post extraction; Class III, well-rounded ridge form, adequate in height and width; Class IV, knife-edge ridge form, adequate in height and inadequate in width; Class V, flat ridge form, inadequate in height and width; Class VI, depressed ridge form, with some basal loss evident. bScoring system: 0, no stability, when a denture base demonstrates extreme rocking on its supporting structures under pressure; 1, some stability, when a denture base demonstrates moderate rocking on its supporting structures under pressure; 2, sufficient stability, when a denture base demonstrates slight or no rocking on its supporting structures under pressure. cScoring system: 0, no retention, when a denture is seated in place, it displaces itself; 1, minimum retention, when a denture offers slight resistance to vertical pull and little or no resistance to lateral force; 2, moderate retention, when a denture offers moderate resistance to vertical pull and little or no resistance to lateral force; 3, good retention, when a denture offers maximum resistance to vertical pull and sufficient resistance to lateral force
