Resumen
RODRIGUEZ HERNANDEZ, Yolday et al. Outcomes on the use of mini-implants as an anchorage in Orthodontics molar intrusion movement. Gac Méd Espirit [online]. 2021, vol.23, n.1, pp. 12-23. Epub 01-Abr-2021. ISSN 1608-8921.
Background:
Tooth intrusion is one of the most dangerous movements in orthodontics, it requires sometimes the maximum anchorage offered by mini-implants.
Objective:
To evaluate the use of mini-implants as anchorage in molar intrusion movement.
Methodology:
It was conducted a pre-experimental study with 6 patients who needed molar intrusion, at the Sancti Spíritus Provincial Stomatology Clinic from 2011 to 2014. Theoretical and empirical methods were used and the succeeding variables were studied: stability, mini-implant location, force magnitude, intrusion movement time, associated clinical alterations and patient acceptance.
Results:
3 patients showed mini-implants high stability and mobility lower than 1 mm in the remaining 3. The most frequent clinical complications were inflammation and bleeding; intrusion movement was achieved in an average time from 8 to 9 months in 5 patients and only 1 patient required the mini-implant removal. The patient´s level of acceptance was Medium.
Conclusions:
Outcomes on the use of mini-implants as anchorage in molar intrusion movement were satisfactory in the treated patients.
