- Orthodontics 650
This course is designed to provide the 5th year student with an understanding of the development of normal dento-facial structures and the etiology, diagnosis, prevention, inhibition, and treatment of various types of malocclusions, including congenital and developmental dento-facial deformities. Emphasis is given to the viewpoint that the processes of making a diagnosis and planning a treatment are problem-oriented inference maneuvers. Possible influences of the function and form of the tongue and perioral soft tissues relevant to the development and maintenance of malocclusions, and the treatment methods used to eliminate these influences, are also discussed. Socio-psychological development of young patients during their growing period is also referenced.
Laboratory exercises give the student an ability to design, fabricate, and adjust removable and semi-fixed orthodontic appliances.
A collection of orthodontic records and its analysis for diagnosis and treatment planning are covered in the preclinical exercises to prepare the student for clinical exercises in Course 660.
At the end of the Course 650, the student should be able to:
1. Describe the recognized orthodontic terms that designate the positions and relationships of the jaw and teeth.
2. Describe the major sites of growth, and types of bone growth, in the cranial base, naso maxillary complex, and mandible.
3. Describe how differential growth of craniofacial components contributes to changes in size, shape, and proportions of craniofacial structures, as well as to changes in these relationships during postnatal growth and development.
4. Describe the normal eruption sequence of teeth in the deciduous and permanent dentitions, and the factors that interfere with the normal eruption pattern.
5. Describe the normal change in dental arches associated with transition from the deciduous to the permanent dentition.
6. Describe the general and local factors that may predispose one to the development of malocclusions.
7. Describe the normal mental developmental stages and outline specific psychological factors that may influence the development of malocclusions.
8. Describe the inference process employed in developing orthodontic diagnoses and treatment planning.
9. Describe the techniques used in collecting, producing, and analyzing orthodontic records, such as interviews, questionnaires, cephalometric radiographs, panoramic radiographs, intra oral examinations, and intra oral and facial photographs.
10. Describe the classification systems of malocclusions such as Angle classification and Ackerman-Proffit classification.
11. Perform arch length analysis.
12. Describe the histology, physiology, and biomechanics of orthodontic tooth-movement.
13. Describe the different types of orthodontic anchorage and their practical applications.
14. Describe the basic design of the edgewise treatment system.
15. Design, construct, and adjust basic components of removable and semi-fixed orthodontic appliances, including an active plate, a functional appliance, and a lingual arch appliance.
16. Describe the difference between camouflage and surgical-orthodontic treatment strategies.
17. Describe the purpose of, and the practical method for, orthodontic tooth-movement.
18. Select and fit preformed bands, perform spot-welding of molar tubes in to the bands, and adjust headgear.
19. Describe the names and uses of orthodontic instruments and materials.
20. Describe the concept of 'informed consent' in providing orthodontic treatment.
