How to minimize errors and complications

Malocclusions are of skeletal and/or dento-alveolar origin. Growth of the craniofacial skeleton is mainly under genetically control, but early dento-alveolar corrections can facilitate the utilization of growth and compensate for most skeletal deviations. In relations to adult patients application of intra-and inter-arch force systems orthodontic appliances generate dental and dento-alveolar changes that are often unpredictable. Before treating a malocclusion the problems to be solved have to be identified and the exact tooth movements needed to solve the problem have to be defined. Only one line of action of the active force can generate the desirable displacement. This force can, however, be generated by several appliances. Every treatment is carried out in phases and it is crucial to differentiate between the active and the reactive unit in each stage of treatment. The treatment goal can only be maintained when it is compatible with normal function.
Based on the lecture the doctor will be able to:
1) Work up a detailed problem list for any malocclusion;
2) Divide the treatment into phases;
3) Define the line of action needed to generate a specific tooth movement.
Several appliances may, on the other hand generate the same line of action of the force In order to obtain a maintainable correction malocclusion the problem must be localized. Only when the deviation is identified the needed tooth-movements can be determined. For each well defined tooth-movement there is only one correct force system. The shortest distance between two points is a straight line This force system can, on the other hand be obtained by many appliances. can be defined and corresponding appliance generated. For each tooth movement defined in thee planes of space only one line of action of the force system is correct.
