 PROGRAMME

8:30 to 9:00: WELCOME

9:00 to 9h45: SARPE and Mandibular Symphyseal Distraction Osteogenesis
Transverse skeletal deficiency is a common clinical problem associated with narrow basal and dentoalveolar bone. Bimaxillary transverse distraction osteogenesis for correction of OSA was first reported by Conley & Legan (2006). Mandibular symphyseal distraction osteogenesis (MSDO) evolve form tooth anchor device to bone anchor device for a better control of the distraction segment in the 3 planes of space. Its success depends on good collaboration between the orthodontist and the surgeon, and on strict patient selection. Throughout case reports, we will review the diagnosis, orthodontic and surgical treatment planning considerations to achieve clinical success. 

Learning objectives:

After this lecture you will be able to:
1-Diagnose patient with transverse mandibular deficiency
2-Understand the distraction protocol
3-Manage the postdistraction orthodontic movement

9:45 to 10:30: MARPE. A paradigm shift in maxillary skeletal expansion.
Case reports
Clinical application of MSE device (Maxillary Skeletal Expander)

10:30 to 11:00: COFFEE BREAK

11:00 to 12:30: Vertical dimension and facial aesthetics
Patients with long anterior face height and anterior open bite often require a surgical approach to correct the vertical dimension. Temporary skeletal anchorage devices now offer the possibility of closing anterior open bite and reducing vertical dimension by intruding posterior teeth. Conversely, patients with reduced anterior facial height (short face syndrome) need elongation of the vertical dimension. In such case, orthognathic surgery is unavoidable if one wants to obtain normal vertical dimension. Review of the literature and case presentation will help to understand the biomechanics and treatment planning of these malocclusion.

Learning objectives:

 Attendees of this lecture will be able to:
•     Determine TADs placement to achieve intrusion of the buccal segment to close an open bite 
•     Assess treatment goal to obtain normal vertical dimension
•     Understand mechanics to increase vertical dimension prior to orthognathic surgery for short face syndrome.

12:30 to 14:00: LUNCH

14:00 to 15:30: Progressive/Idiopathic Condylar Resorption: Case Reports. (this article is approuved for publication in the AJODO)

Abstract:

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.
Throughout 3 case reports, we review the pathogenesis of TM joint degenerative disease and the clinical management of TM joint arthritides.
We emphasize TMJ arthritic disease should be discussed in dental circles as a pathologic entity in the same way our orthodontic colleague discuss arthritic disease in orthopedic circles.
With respect to the degenerative pathology of the TMJ, the treatment goals for affected individuals include restored function and pain reduction. The management modalities used to achieve these goals can range from non-invasive therapy, to minimally invasive and invasive surgery. Most people can be managed non-invasively, and one must acknowledge the importance of disease prevention and conservative management in the overall treatment of persons with TMJ. The decision to manage TMJ-osteoarthrosis surgically must be based on evaluation of the person's response to non-invasive management, his/her mandibular form and function, and the effect of the condition on his/her quality of life.
