Tooth agenesis: dento-skeletal characteristics in subjects with orthodontic treatment need.

AIM

The aim of this study was to analyse skeletal, dental and arch morphology in a group of subjects with dental agenesis and to compare it with a control group.

STUDY DESIGN

2 groups of subjects were selected: an experimental group (84 patients) with tooth agenesis and a control group (84 subjects) without tooth agenesis.

MATERIALS AND METHODS

Skeletal, dental, morphological and aesthetic parameters were studied using lateral and posteroanterior cephalograms and dental casts.

RESULTS

Transversal and sagittal measurements showed a significant decrease in maxillary size associated with tooth agenesis in the agenesis group. No changes were observed in mandibular size.

CONCLUSION

Orthodontists should consider that patients with agenesis present altered craniofacial dimensions.
