Weekly Question and Answer session. May 15, 2019

Once again we had a very interesting question and answer session this morning – and this was well received by all of the online attendees

The first case that was discussed, was a female adult who presented with severe crowding in the lower anterior region, with her mandibular left lateral incisor tooth(tooth 32) blocked out lingually. Our discussion revolved around whether this case should be treated non-extraction or utilise a much easier and more predictable approach by removing the 32 and reducing the potential risks as well as treatment time.

The second case that was discussed was an adolescent who had a posterior crossbite – and even with a first phase of treatment utilising palatal expansion, we did not achieve sufficient expansion on a long-term basis. When he presented in the permanent dentition, he fortunately had a consistent force system that allowed braces to provide the necessary expansion. Discussion involved the prediction of that expansion, and how this patient could have been treated if the teeth were rotated in the opposite direction and hence an inconsistent force system that would have caused further constriction to the arch form. As you will see in the final result – even fixed appliances alone with a good consistent for system can provide significant dental and skeletal expansion and change arch forms significantly.

A further discussion involved how to assess a Bolton discrepancy – and we demonstrated a different approach to the conventional percentage analysis-- and approach which is far easier to use, and provides a more quantitative analysis as to how to resolve any Bolton discrepancy that exists in an individual patient.

I hope you enjoy this recording- and as always I hope that you can join us online on our weekly  Q and A session on Wednesday 7 AM Melbourne time so you can interact fully with the group

In the meantime if you have any questions, comments, cases that you would like to discuss please email these to me geoff@orthoed.com.au 

Hope that these recorded webinars take your orthodontic learning to another level and look forward to seeing you online at one of our weekly sessions
