NUNEZ, Sabina et al. Intercanine and intermolar distance in mixed and permanent dentition. Mem. Inst. Investig. Cienc. Salud [online]. 2022, vol.20, n.2, pp.59-65. ISSN 1812-9528.

Transverse growth space problems in both maxillaries can be predicted by knowing the intercanine and intermolar width distance. The objective of the study was to determine values of transverse measures of arcades in patients with mixed dentition and permanent dentition of the postgraduate degree in Orthodontics of the Latin American Institute of Higher Studies. Descriptive observational cross-sectional study, the temporary and permanent intercanine horizontal linear distances were taken as well as the intermolar distance in permanent first molars in patient study models between 2014 and 2019. One hundred and forty-four patients aged from 8 to 32 years old participated, 41.67% were over 15 years old, 65.28% were women and 52.78% had permanent dentition. The mean maxillary intercanine distance was 33.22 ± 3.95 mm in men and 33.34 ± 3.90 mm in women, the mandibular 27.30 ± 2.81 and 27.40 ± 2.92 mm respectively. The maxillary intermolar distance was 34.16 ± 3.27 mm in men and 34.15 ± 3.26 mm in women, the mandibular 33.97 ± 3.27 and 33.94 ± 3.27 mm respectively. The averages of the intercanine distance were similar by age and sex, while the means of the lower arcades were lower than those of the upper arcade in both sexes. Means of the intermolar distance was similar by age, sex, and arcade.
