Jackson's Triad consists of structural integrity, functional stability, and esthetic harmony. An ideal position of the incisors on its apical base in all three planes of space plays a vital role in achieving this balance. Deep bite (or excessive vertical overlap) is a common symptom associated with Class II malocclusions and can be corrected with various modalities including intrusion of upper and/or lower incisors, extrusion of posterior teeth, and flaring of anterior teeth. The intrusion of the upper and lower incisors is the most effective way of correcting the deep bite, as it moves their root apices closer to the nose and lower border of the mandible, respectively. Intrusion is defined as the "tooth movement that occurs in an axial (apical) direction and whose center of rotation lies at infinity. It is an axial type of translation". It is often associated with an increase in the vertical dimension of the face, as well as an improvement in the aesthetic appearance. Relative intrusion/ pseudo-intrusion of the incisors can also be used, keeping them where they are while the mandible grows and the posterior teeth erupt. This method is used to maintain the mandibular plane angle.

A preven o de movimentos dent rios indesej veis em ambas as arcadas agora poss vel. O uso de pequenos parafusos sseos de tit nio aumentou o envelope do tratamento ortod ntico, fornecendo uma alternativa cirurgia ortogn tica (particularmente na dimens o vertical) e permitindo o movimento dent rio assim trico em tr s planos do espa o. Os mini-implantes proporcionam a vantagem biomec nica que permite um tratamento mais eficaz e eficiente com menos auxiliares e outros aparelhos. A previs o da resist ncia ao movimento dent rio pode minimizar as reac es adversas, conduzir a um tratamento mais bem sucedido de problemas complicados e proporcionar um tratamento eficiente em menos tempo. Os dentes podem ser movimentados diretamente (em massa, sem perda de ancoragem) para as suas posi es finais. T cnicas e informa es aprimoradas nas ltimas duas d cadas permitiram que os cl nicos obtivessem um posicionamento dent rio mais ideal.

La prevenzione di movimenti dentali indesiderati in entrambe le arcate ora possibile. L'uso di piccole viti ossee in titanio ha ampliato l'ambito del trattamento ortodontico, fornendo un'alternativa alla chirurgia ortognatica (in particolare nella dimensione verticale) e consentendo il movimento asimmetrico dei denti in tre piani dello spazio. Le miniseghe offrono un vantaggio biomeccanico che consente un trattamento pi efficace ed efficiente con un minor numero di ausili e altri dispositivi. La previsione della resistenza al movimento del dente pu minimizzare le risposte avverse, portare a un trattamento pi efficace di problemi complicati e fornire una cura efficiente in meno tempo. I denti possono essere spostati direttamente (in massa senza perdita di ancoraggio) nelle loro posizioni finali. Il miglioramento delle tecniche e delle informazioni negli ultimi due decenni ha permesso ai medici di ottenere un posizionamento dei denti pi ideale.

Les mini-vis offrent un avantage biom canique qui permet un traitement plus efficace et efficient avec moins d'auxiliaires et d'autres appareils.

Les dents peuvent tre d plac es directement (en masse sans perte d'ancrage) vers leur position finale. L'am lioration des techniques et des informations au cours des deux derni res d cennies a permis aux cliniciens d'obtenir un positionnement plus id al des dents.

Es ist nun m glich, unerw nschte Zahnbewegungen in beiden Kieferb gen zu verhindern. Die Verwendung von kleinen Titan-Knochenschrauben hat die M glichkeiten der kieferorthop dischen Behandlung erweitert und bietet eine Alternative zur orthognathen Chirurgie (insbesondere in der vertikalen Dimension) und erm glicht asymmetrische Zahnbewegungen in drei Raumebenen. Minischrauben bieten den biomechanischen Vorteil, der eine effektivere und effizientere Behandlung mit weniger Hilfsmitteln und anderen Apparaturen erm glicht. Die Vorhersage des Widerstands gegen Zahnbewegungen kann unerw nschte Reaktionen minimieren, zu einer erfolgreicheren Behandlung komplizierter Probleme f hren und eine effiziente Versorgung in k rzerer Zeit erm glichen. Die Z hne k nnen direkt (en masse ohne Verlust der Verankerung) in ihre endg ltige Position bewegt werden. Verbesserte Techniken und Informationen in den letzten zwei Jahrzehnten haben es den Zahn rzten erm glicht, eine idealere Zahnpositionierung zu erreichen.

Prevention of undesirable tooth movement in both arches is now possible. The use of small titanium bone screws has increased the envelope of orthodontic treatment, providing an alternative to orthognathic surgery (particularly in the vertical dimension) and allowing asymmetric tooth movement in three planes of space. Miniscrews provide the biomechanical advantage that allows more effective and efficient treatment with fewer auxiliaries and other appliances. Predicting resistance to tooth movement can minimize adverse responses, lead to more successful treatment of complicated problems, and provide efficient care in less time. Teeth can be moved directly (en masse without anchorage loss) to their final positions. Improved techniques and information over the last two decades have enabled clinicians to obtain more ideal tooth positioning.
