[Anthropometric proportion parameter of hand-face verification].

By studying the criteria used in the pictorial art field, the Author obtained an anthropometric parameter. This appears to be a procedure to investigate and verify the ideal pattern as well as to calculate the vertical ratios and relationships of the face in different ages. The Pantaleoni's parameter shows the correspondence between Sn-Gn skin measurement and the interphalangeal flexion plica pf2-pf5. It is a parameter of verticality which changes depending on age, from youth to senility, and can be used in different dentistry areas. In orthognathia it allows to draw a borderline between true orthognathia and pre-surgical orthodontics; moreover it allows to detect if abnormal occlusion involves either maxillary or jaw-bone.
