Orthodontic biomechanics for aligning ectopic teeth

In orthodontics the application of appropriate forces and moments is necessary for full control during tooth movement. The chosen appliance will influence the rates of tooth movement, potential tissue damage and pain response. An understanding of applied biomechanics guides the orthodontist to determine how to maximize the former (the application o...

Excellent treatment results can be achieved with “old school” conventional torquing when tooth anatomy and the characteristics of the orthodontic appliance are sufficiently considered during torque application. An undersized beta-titanium 0.016 x 0.022-inch archwire/Warren spring combination for palatal crown torque in inverted 0.022-inch slots of...

Evidenzbasierte Kieferorthopädie im Spiegel von Kosten/Nutzen Analysen. Bei der Bewertung des Nutzens kieferorthopädischer Behandlungsmaßnahmen ist die alleinige Berücksichtigung evidenzbasierter Studien höchster Qualität nicht zielführend. Bei der Bewertung kieferorthopädischer Behandlungen sollte vorrangig die Änderung / Verbesserung der mundgesu...

A favourable but critical review of 20 years of evidence-based orthodontics

Literature review on the indications and use of different kinds of retainers

Biomechanics for molar uprighting. An appropriate method for molar uprighting should be choosen for each particular case. Clinical problems are generally due to the extrusive component of simple tip-back methods. When necessary the optimal technique should apply an intrusive force to the molar as its axial inclination is corrected. For improved mol...

Our objective was to evaluate the effect of different NiTi archwire bracket combinations on force levels and moments generated in high canine cases. Methods: The following areas of recent literature were searched: in vitro studies on force levels in complex tooth alignment, conventional vs self-ligating brackets, effect of diameter and archwire cro...

Purpose: To document and evaluate the literatur regarding outcomes of implant restorations in the anterior maxilla in cases of agenesis of the lateral incisor/s with regard to esthetics, to provide guidelines for clinicians and to articulate questions in this area to be answered by future research. Materials and Methods: The following areas of the...

Purpose: To identify and document the literature regarding treatment objectives for anterior disc displacement with reduction / reciprocal TMJ clicking and to formulate treatment recommendations. Materials and methods: the following areas of the available literature were scrutinized: diagnostics, etiology and treatment objectives of anterior disk...

Literature review: Anterior disc displacement with reduction. Diagnostics, Etiology and treatment objectives. What the orthodontist should know.

Literature review: Indications for CBCT imaging in certain cases of ectopic canines and resulting treatment objectives.

Biomechanics of temporary anchorage devices.

Lirerature review: The indication of cbct radiographs in certain cases of ectopic canines

What seems to be the latest will never replace the need to apply sound biomechanics. Biomechanics for the treatment of impacted and displaced canines. Canine recovery mechanics and their side effects are discussed to provide critical information for appropriate selection of an optimal appliance.

Activation of partially bracketed arch wires in the transverse dimension to produce first-order rotations of the molars and constriction or expansion of intermolar width. Symmetrical V-bends, asymmetrical V-bends and step bends are used to generate forces and moments to produce the desired tooth movement.

Activation of partially bracketed arch wires in the vertical dimension to produce second-order rotations of the molars and intrusion or extrusion of anterior teeth. Symmetrical V-bends, asymmetrical V-bends and step bends are used to generate forces and moments to produce the desired tooth movement..
