Previous issue date: 1977 / Resumo: Não informado / Abstract: The author used model casts from dental arches of 68 children born in Piracicaba, aged about 3 and 6 years old, to observe the frequency relationship between arches of Type I and Type II; presence or absence of primate spaces; kinds of deciduous canine anteroposterior relation; overbite and overjet degrees, in the deciduous dentitions with vertical terminal plane and terminal mesial step. The sample was composed of 34 children with deciduous molars in vertical terminal plane and 34 children with deciduous molars in terminal mesial step, distributed equally by age and according to sexo The findings may be summarized as follows: 1) Arches of Type I occurred more in the maxila and arches of Type II occurred more in the mandible in both classes of dentition, in vertical terminal plane and in terminal mesial step. 2) In the mandible, both patterns of terminal relation
presented the same frequency, in arches of Type I and Type II. 3) In the maxila, dentitions with terminal mesial step presented arches of Type I more frequently than did the dentitions with vertical terminal plane. The opposite occurred with the frequency of arches of Type II. 4) Dentitions of Type I (arches Type I in maxilla and mandible), were more usual when terminal mesial step appeared and dentitions of Type II (arches of Type II in the maxilla and mandible) were more frequent in vertical terminal plane. 5) Primate spaces were found more in terminal mesial step dentitions, than in dentitions with vertical terminal plane. In the mandible, more accentuated diversity was observed. All cases studies presented bilaterality. 6) Regarding the mandible and the maxilla, the greater frequency of primate spaces and the lesser frequency of their absence were usually found more in dentitions with terminal mesial step than in vertical terminal plane dentitions. 7) As revealed by the association between primate spaces and arch types, there were 11 combination patterns for dentitions with vertical terminal plane and 6 for dentitions with terminal mesial step. 8) Dentitions with terminal mesial step presented with more frequency, Type A occlusal relationship between deciduous canines. In vertical terminal plane dentitions, Type B occlusal relationship occurred with greater frequency. 9) Vertical terminal plane dentitions showed moderate and severe overbite more frequent1y, and slight overbite with less frequency, than dentitions with terminal mesíal step. 10) In dentitions with vertical terminal plane, ideal overjet occurred less frequently and increased overjet more frequently than in terminal mesial step dentitions / Mestrado / Mestre em Ortodontia
