Comparación clínica y radiográfica del efecto del péndulo con anclaje esquelético vs. dentoalveolar

ABSTRACT: This study seeks to clinically and radiographically compare the effects produced by the distalization pendulum in both skeletal and dentoalveolar anchorage, in patients with Class II malocclusions at the Universidad de Antioquia’s School of Dentistry. Methods: a pre-experimental comparative study was carried out on a sample of 19 patients aged 15-26 years, divided into two groups: 9 patients treated with bone anchorage pendulum and 10 with dentoalveolar anchorage pendulum. Lateral cephalic radiographs of each patient were taken and study models were done at the beginning and the end of evaluation period (6 months). Results: both clinical and radiographic results show significant differences in the effects produced at the incisors and molars. The pendulum with dentoalveolar anchorage presented an average incisor proclination of 4°, while the pendulum with skeletal anchorage showed no variation. Concerning the effect produced in molars, a greater amount of distalization as a result of inclination was observed in the pendulum with dentoalveolar anchorage (14.1°) in comparison to the one with skeletal anchorage (7.34°). Conclusions: with both modalities, the pendulum proved to be effective for molar distalization; nevertheless, it is important to bear in mind the desired effect on the incisors, as each technique produces different results.
