Surfaces of edentulous jaw vary in patients with different skeletal classes. The aim of this study was to assess surfaces of supporting tissue areas of edentulous jaws of patients with the skeletal class 2. Materials and method. Thin aluminum phoils (0.5 mm of thickness) were adapted on plaster's surfaces of 47 pairs of edentulous jaw casts. Phoils were positioned to millimetric paper and surface of each foil; was calculated. Additionally, surfaces were measured by plan-meter (G. Coradi, Switzerland, serial no. 49823). The error of measurement was 1%. Skeletal class of edentulous jaws was analyzed on lateral cephalometric radiographs with the analyses of ANB (SNA-SNB) angle. Results. Surfaces of edentulous upper jaws were calculated: 4521 ± 471mm2 for men, and 4386±935 mm2 for women. Surfaces of edentulous lower jaws were 1571 ± 379 mm2 for edentulous men, and 1524 ± 449 mm2 for edentulous women. ANB values were higher than 4o. Dissimilarity of numerical values of surfaces of edentulous upper jaws was 7,2 % when patients with skeletal class I and skeletal class II were compared, but the surfaces of edentulous lower jaws were 16,1 % smaller in patients with skeletal class II. Conclusion. Surfaces of edentulous jaws of men were larger in comparison to women. Edentulous surfaces to the right side were not absolutely symmetric with surfaces to the left side. Patients with skeletal class II had smaller jaws.
