Webinar course Orthodontics

In this presentation, we will show some failures in the use of standard techniques and we will discuss how it is possible to avoid side effects and make the therapy outcomes more predictable, with the use of a rational and individualized mechanics. This different approach, based on the deep knowledge of orthodontic biomechanics, ultimately raises the limits of orthodontic therapy and allows for the controlled treatment of very complex cases.
You will learn:
1. The basic concepts of statically indeterminate mechanics;
2. Burstone’s 6 geometries;
3. The role of friction in dental movement determination;
4. How inconsistencies are generated using a continuous archwire;
5. The “Force Driven” mechanics as an alternative to “Shape Driven”;
6. Force System and Dental Movement;
7. Anchorage Analysis;
8. Mechanics Design Examples for Statically determinate Appliances with Clinical Cases

If orthodontic treatment is to be of benefit to a patient, the advantages it offers should outweigh any possible damage it may cause.
Signs Indicating for Orthodontic treatment:
• Facial imbalance or asymmetry;
• Oral habits dysfunctions;
• Crowding, misplaced, or blocked-out teeth;
• Open bites and deep bites;
• Protruding teeth and facial unbalance;
• Retrusion of the chin in Class II.
An attractive smile is a wonderful asset. It contributes to self-esteem, self-confidence and self-image. But we must evaluate the Risks and the Benefices before to take a decision for the patient and family. Risks increase the possible failures and relapse. Risks on Facial balance:
• Flatten faces with extractions protrusion of the face on non-extraction treatment;
• Anchorage lost;
• Temporomandibular injuries. Risks on teeth and periodont:
• Enamel decalcification and fracture;
• Pulp Vitality, Root resorption;
• Uncontrolled periodontitis;
• Uncontrolled oral hygiene.
So, acknowledgement of failure is important but an orthodontic specialist should have the possibility to treat their patients with a minimum of risks with: сlear and strong diagnosis for treatment decision.
• Respect of the limits of the denture: transversal, vertical and sagittal;
• Do not tip labialy the anterior teeth;
• Overcorrect the overbite;
• Overcorrect the class II discrepancy;
• Maintain arch form and arch width;
• Maintain vertical dimension;
• Think about ROOT, not only Crown;
• BONDING.
• High degree of control during the therapy orthodontic and/or orthopedics including the Ortho-surgical association.
Orthodontics is not only a bracket slot!
The Edgewise concept is based on analysis and strategy with the management of the denture to obtain the best functional occlusion that protect TMJ.
The orthodontic treatment is the service rendered to the patient first !Occlusal management depends on the position of the teeth before the treatment and the movements planned according the objectives.There are two parameters for tooth movement: the force in the wire and the force received by the tooth. The bracket, just transmits the force. So whatever the bracket slot is, in shape and size, the only important thing, is the result of the force system that will move the tooth and group of teeth.
The patients should be aware that stability cannot be guaranteed, and that maintenance depends on his compliance. It seems to be a widespread myth that orthodontic results remains stable. Despite this poor situation, we have some arguments for treating malocclusions with an effective stability.

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.

Class II malocclusion does not self-correct in growing patients. The Class II skeletal pattern is established early and remains until puberty if no orthodontic intervention is performed. To this date, several authors have discussed the relationship of the initial malocclusion characteristics with the effectiveness of orthodontic treatment and the stability of the corrections obtained. 
Normally, orthodontic treatment takes a long time and uses complex techniques, usually achieving good results; however, these results may be lost in varying degrees after the removal of appliances and retainers. Orthodontic relapse includes crowding or spacing of teeth, and loss of overbite, overjet correction, and loss of Class II molar relationship correction.
Orthodontic changes of the position of the first permanent molars have a great tendency to relapse. Some authors affirm the with time, in adults, changes that occur in molar relationship are always towards Class II relation. The changes are of small magnitude and independent of the type of initial malocclusion and the type of treatment. Other authors suggest that, in the long-term, there is relapse in molar relationship and that changes in incisor position and intercuspation of the posterior teeth are statistically significant. 
The real problem is that we don’t have clear the real etiology of a Cl II malocclusion. Only if we have the understanding of the morphologic characteristics of a malocclusion can we know what needs to be changed in order to treat our patients, growing and adults, from a full Cl II molar relationship, to a stable Cl I, correcting also the skeletal Cl II. 
Some of the common mistakes in treating a Cl II is wrong diagnosis, high pull headgear, premolar extractions and the use of Cl II elastics.
