What about the curve of Spee?

A case report by El-Bokle and Abbas (El-Bokle D, NH. novel method for the treatment of Class II malocclusion. Am J Orthod Dentofacial Orthop 2020;158:599-611) in October issue reported 2 cases malocclusion which patients were treated with inclined bite raisers beveled 45° combined short light intermaxillary elastics, showing improvement occlusal profile relationships both at end treatment. The article was quite interesting appreciated us, but we have some doubts. In bonded elastics construction section manuscript, it highlighted that choice teeth depends on overbite patient presents beginning a deepbite, authors suggest placing risers premolar region to facilitate extrusion molars. One question would be regarding Spee curve.
