“…A sharply concave Spee occlusal curve in 8 patients (15.38±5 %) with three possible variants of dental arches in dolichognathia with retrusion of the incisors in 3 patients (5.77±3.23 %) and with protrusion of the incisors in 5 patients (9.61±4.08 %). The proposed method made it possible to quickly, with low labor costs and a high degree of accuracy, quantitatively determine the depth of the Spee occlusal curve and thereby confirmed the theoretical research [1,4,6,9,11,15] devoted to the problems of increasing the aesthetic and functional efficiency of constructing artificial dentitions in dental prosthetics with a different ratio of the jaws.…”
