Objective :

Determine the dimensions of the facial bone ridge of the maxillary incisors with indication of immediate implantation.

Patients and method:

A cross-sectional study was carried out in patients in need of single immediate implant placement in the upper incisor area, during the period from January-2015 to December-2017. Sagittal tomographic sections were used to determine the height and thickness of the vestibular alveolar bone ridge. The thickness measurement point was located 4 mm apical to the amelocementary junction. A T-student analysis was used to compare the variables according to age, gender, and dental group, with a 95% confidence interval.

Results:

298 images were included in the evaluation. The mean height was 10.68 mm, there were no differences when comparing the groups. The mean thickness was 0.73 mm, statistically significant differences in thickness were observed when comparing age and gender, but not in the dental group.

Conclusions:

The height of the vestibular alveolar bone of the upper incisors could be sufficient to place immediate implants within a bone framework. However, the thickness observed would result in the need to complement the implantation with guided tissue regeneration techniques.
