INTRODUCTION TO ORTHODONTIC EDUCATION IN BULGARIA OF DIGITAL TECHNOLOGIES AND 3D ARCHIVING

Orthodontic treatment, especially during the period of active growth, can significantly affect the development of the jaws and teeth. Treatment with extraction of molars is more complicated because the space that needs to be closed is larger than the premolar spaces and the time of treatment will be longer. However, in cases where we have a lack of space, teeth protrusion or dental asymmetry, and the extraction of permanent teeth is indicated, the damaged molars should be the first option for extraction when premolars are in better condition. The third molars in different ways are affected by orthodontic therapy. One of them is orthodontic treatment by applying the extraction of the third molars, this situation being widely explored. Extraction of third molar for orthodontic reasons is justified when it prevents the eruption of the second molar or otherwise affects the other teeth. The indications of extraction and selection of teeth to be removed depend on the specific aspects of malocclusion. Premolars are teeth that are usually extracted from orthodontic reasons, but this is not the rule and depends on individual treatment needs. The decision to correct the malocclusion with teeth extraction should be based on the ratio of the size of the dental arch with the size of the teeth, facial appearance and other factors arising from the diagnosis itself. Indications for extraction of the third molars during orthodontic treatment are: mandibular incisor crowding, if they in some way constitute a obstruction of orthodontic treatment as well as preparation for orthognathic surgery. The success of an orthodontic treatment involving the extraction of molars is directly related to the patient complaints and psychological profile, the absence of diseases and skeletal discrepancies, the professional experience as well as the fact whether the patient underwent previous orthodontic treatment with extraction. Patients with partially or completely non-erupted teeth are significantly more likely to have certain consequences: before, during or after the orthodontic treatment. Therefore, orthodontists need to raise patient awareness of these consequences in the context of orthodontic treatment.
