IMDO - Intermolar Distraction Osteogenesis for Class II Patients
Speaker: Peter Kessler
Dental Class II is the most common indication for combined orthodontic-orthognathic treatment. Intermolar mandibular distraction osteogenesis (IMDO) treatment can performed during the growth spurt, to avoid surgery at a later age. The aim of this study is to present our first experience with IMDO.
This is an ongoing case series of patients who undergo IMDO. All patients show mandibular retrognathism and orthodontic treatment with functional appliances was/is not successful.
In total 20 patients (mean age of 14.8 years (SD=0.9ys) were operated on so far. All patients achieved a Class I occlusion. An average length gain of 9.6mm (SD=3.7mm) was reached. The average time between insertion and removal of the distractors was 4.6 (SD=1.5) months. In one case a premature consolidation was seen. Technical aspects, risks and chances will be discussed.
Conclusion: An advantage is the manageable overall treatment time. Furthermore, the question of long-term stability of the achieved correction of the bite position is open. The question of the dynamic distraction treatment in relation to temporomandibular joint changes can also only be answered in the long term.
