[Spontaneous dento-cephalometric changes after the young adult stage]

As far back as 1975, this study has been undertaken longitudinally from sample of 723 subjects, aged from 18 to 89. Its main objective was primarily to point out the different factors involved in both dental and skeletal structures changes, in adults when a full denture was functional. Also, the author has tried to assess if this evolution can be quantified on lateral cephalograms, according to sex and architectural type.
