  1. Eichner A1: All four occlusal support zones are intact with complete contact, Eichner A2: All four occlusal support zones are intact, but teeth are missing in either the upper or lower arch, Eichner A3: All four occlusal support zones are intact, but teeth are missing in both arches, Eichner B1: Three occlusal support zones remain intact, Eichner B2: Two occlusal support zones remain intact.
  2. *Chi-squared test.
