Introduction An orthodontist's primary objective is to diagnose and describe the characteristics of any particular malocclusion. It has been reported that when the anteroposterior dimension of the maxilla is either reduced or increased, the measured dentoalveolar and skeletal parameters gets affected in other dimensions also.

Aim This study aims to assess and compare the dentofacial characteristics in individuals with different skeletal morphology (normal, retrognathic, and prognathic maxilla).

Materials and Methods A total of 194 individuals in the age group of 18 to 32 years were grouped as group I (34 males, 33 females) with normal maxilla, group II (30 males, 32 females) with retrognathic maxilla, and group III (34 males, 31 females) with prognathic maxilla. The measurements of N-A and anterior nasal spine to posterior nasal spine were the basis for selecting the individuals. The dentoalveolar characteristics were assessed using 17 lateral cephalometric and 08 posteroanterior (P-A) cephalometric parameters.

Results The data of the study when analyzed statistically using sample “t” test (p < 0.05), revealed significant differences between the genders within the groups. All 08 characteristics measured in the P-A cephalogram showed had significant differences. Pairwise comparison between the groups was performed using the Tukey post hoc test (p < 0.05) and significant differences in various dentoalveolar characteristics were observed between the groups.

Conclusion Dentoalveolar and facial parameters showed a significant degree of sexual dimorphism associated with maxillary morphology in all three groups of individuals. The majority of the parameters showed male dominance, and the differences were statistically significant. Statistically significant differences were observed in dentofacial characteristics in individuals with different skeletal morphologies
