Online course on orthodontics: OrthoEvolution 3.0

- The etiology of anterior open bite and treatment modalities;                                          
- Relapse after anterior open bite correction;
- The factors that affect relapse after anterior open bite correction      

Anterior open bite is difficult to treat because it is caused by the interaction of multiple etiologic factors such as heredity, unfavorable mandibular growth patterns, nasopharyngeal airway obstruction, digit-sucking habits, tongue posture and activity, and an imbalance between the posture of the jaws. Proper diagnosis and treatment planning, successful treatment, and retention are important to the long-term stability of open bite treatment. In this lecture, various treatment modalities of anterior open bite and relapse will be discussed. After the lecture, clinicians will be able to treat and finish anterior open bite cases more efficiently and successfully while minimizing the chance of relapse.

- Understand reasons for relapse and how that helps us consent our patients for treatment and reduce instability during our treatment and retainer planning
- Compare clear plastic retainers with other retainers using the best evidence
- Explore different types of material for clear plastic retainers
- Look at ways to reduce failure and complications with clear plastic retainers
- Practical tips for using clear plastic retainers

- Discuss how to prepare for the new ABO Scenario-based Oral Clinical Examination in diagnosis and treatment planning, treatment implementation and management, and critical analysis and outcomes assessment in AOB cases;
- Identify clinical situations in which CBCT imaging and TADs would be beneficial in AOB correction;
- Understand clinical applications and biomechanical considerations of orthognathic surgery vs. TADs in challenging AOB cases

Anterior open bite (AOB) can be corrected by orthognathic surgery or orthodontic treatment. Severe skeletal, facial, and functional problems should be corrected by orthognathic surgery, but combining cone-beam computed tomography (CBCT) and temporary anchorage devices (TADs) provides an efficient and accurate way to correct AOB. Nowadays, by using TADs, we can expand orthodontic boundaries. In this lecture, various clinical applications of TADs and orthognathic surgery will be discussed in challenging AOB cases along with the new American Board of Orthodontics (ABO) Scenario-based Oral Clinical Examination domains. After the lecture, clinicians will be able to treat and finish anterior open bite cases more efficiently and successfully while minimizing the chance of relapse.

- Differential diagnosis of pathologies that cause facial asymmetry- The effect of unilateral condylar hyperplasia in a growing and non growing individual. - Тhe effect of condylar fracture or trauma (impact) to the joint that may affect mandibular growth. - Тhe diagnostic test and surgical treatment of hemimandibular hyperplasy and facial asymmetry

- Тhe pathogenesis of TM joint degenerative disease- Тhe clinical management of TM joint arthritides- Progressive/Idiopathic Condylar Resorption- Management of unsalvageable TMJ

Progressive condylar resorption (PCR) also known as idiopathic condylar resorption (ICR) is an uncommon, aggressive, degenerative disease of the temporomandibular joint (TMJ) seen mostly in adolescent and young women. This condition leads to loss of condylar bone mass, decrease of mandibular ramal height, steep mandibular and occlusal plane angle, and an anterior open bite.
