Summary

The anchorage management in orthodontic treatments has been a constant challenge, the use of miniplates may be a viable solution to this query. The objective of this study was to determine the morphological differences in the area of insertion of orthodontic miniplates in the anterior and posterior mandibular regions, comparing them between age, sex, biotype and skeletal class. In this analysis 40 cone-beam records of patients were studied, bone thickness measurements were carried out, the sites that allowed the positioning of a miniplate were identified and compared between sex, age groups, biotype and skeletal class. Significant differences were observed between men and women at the anterior mandibular level, in men greater bone and cortical thicknesses were observed. No significant differences were observed between adult and young patients at the anterior mandibular level, but there were differences at the posterior mandibular level. The area 3 mm below the 2nd molar was not a reliable area for the insertion of mini plates, since many of the patients had no bone in that area. Miniplates are a safe anchoring resource which must be adapted to each patient.

KEY WORDS: orthodontics, orthodontic anchorage techniques.
