Orthodontic treatment of severe crowding malocclusion with temporomandibular joint closed-lock by means of multi-loop edgewise archwire: a case report
In this case report, crowding malocclusion with TMJ (temporomandibular joint) closed lock was treated with modified offset archwire (MOAW) and multi-loop edgewise archwire (MEAW). Owing to the TMD (temporomandibular disorder) problems, we decided to extract the lower third and upper second molars. Crowding in the upper and lower arches was successfully treated with the improvement of TMD. Condylar movement was improved by orthodontic treatment with ΔY shift noted on condylographic evaluation. Two years after the treatment, the occlusion was fairly stable.
