Abstract: The aim of the present study was to demonstrate and measure the normal alveolar ridge, on threedimensional(3D) volumes obtained when performing the screening for the end of the Ist trimester. A group of 121 pregnant patients, each pregnancy with a single fetus. Each fetus had a 3D volume acquired between 11+0 and 13+6 weeks. The alveolar ridge area measurement was performed by two different operators. From 120 volumes, at 100 fetus volumes, we obtained using multiplane processing, sections similar to the one from the miscarriage (82.64%). Measurement of alveolar ridge area was possible in cross section obtained in all 100 volumes, without any significant differences between the two operators (mean 0.1900 cm2, 95% CI: 0.1754-0.2046, 0.1908 versus mean, 95% CI= 0.1762-0.2054, p= 0.9389). Conclusions. Analysis of volumes, at the end of the Ist trimester ultrasound screening, obtains sections which contain and show the normal alveolar ridge, part of the palate.
