AbstractObjective: To approbate the complex approach for assessment of second molar mesialization outcomes with the use of orthodontic mini-implants. Material and Methods: The sample consisted of 62 patients, divided into study (n=32) and control group (n=30). Mesialization procedure in the study group was conducted with the use of braces system and orthodontic mini-implants as additional anchorage devices, while in control group mesialization was provided only with the use of the brace system. Dynamic registration of bone level changes and the entire range of tooth movement were carried out on digital orthopantomograms obtained with the use of Planmeca ProMax 2D. Results: Findings of orthopantomographic (OPG) analysis have shown that cases of second molar mesialization with the use of mini-implants as temporary anchorage characterized with more stable conditions of bone levels around displaced teeth compare to cases, where mesialization was provided only with the use of braces systems without any additional anchorage. The terms of treatment in the study group with the use of dental mini-implants as the anchorage was reduced by 8.8 ± 0.12 months compared to the control group (p<0.05). Conclusion: The use of orthodontic miniimplants as anchorage constructions during the mesialization of the mandibular second molars contributes to the reduction of treatment duration and support the more prognostic movement of teeth, that does not provoke significant pathological changes in the levels of the surrounded alveolar ridge and minimize the risk of associated periodontal complication occurrence.

Consideraciones básicas para la mesialización de molares. Revisión de literature

“…Para evitar movimientos no deseados en la arcada dentaria superior y en la arcada dentaria inferior se utiliza el sistema de anclaje de mini implantes en el hueso, aumentando las posibilidades del tratamiento de ortodoncia, así mismo se logra movimientos dentarios asimétricos en los tres planos del espacio, por ende, los mini implantes tienen numerosas ventajas biomecánicas, con las cuales se logra una mayor eficacia y eficiencia en el tratamiento (26). Es así como, la evolución del tratamiento conllevó a que los mini implantes ofrezcan varias ventajas, una de las principales es la falta de colaboración del paciente, así como también que su inserción en los diferentes sitios anatómicos se realizara de forma sencilla (18). De acuerdo con los sitios de colocación se podría considerar que la región dentoalveolar bucal es el lugar más frecuente para la inserción y colocación de estos, por lo que, especialmente en la maxila la zona anterior del paladar parece ventajosa, ya que todos los dientes pueden moverse sin ninguna interferencia de los mini implantes (24).…”

Two-dimensional radiographs versus cone-beam computed tomography in planning mini-implant placement: A systematic review

“…Clinical studies have shown that mini-implants provide greater predictability ( 2 ) and mechanical stability in orthodontic treatment ( 3 ). Interradicular sites are used for retraction ( 4 ), mesialization ( 5 ), distalization ( 6 ), intrusion ( 7 ), verticalization ( 8 ), or traction ( 9 ). Paramedian anchorage on the palate is recommended for molar distalization ( 10 ), or in cases of maxillary atresia ( 11 ).…”
