Introduction/Context/Diagnosis
This patient reported to the orthodontic clinic with a chief concern of anterior cross bite and multiple non-restorable posterior teeth. Patient had full cusp class III molar and canine relationship bilaterally, with anterior cross bite from #7 to #11. Patient also presented with multiple teeth with severe decay, failed root canal treatment, pulp polyp, and fracture. She was planned for extraction of #29, #30, #18, #19, #1, and #16. She hoped to get a minimum amount of implant restorations as possible after extraction and orthodontic treatment. Full fixed appliance and two anterior TADs (temporary anchorage device) were used for her treatment. It was decided to coordinate extraction appointments with orthodontic treatment to maximize the use of the RAP effect (regional acceleratory phenomenon). After extraction of non-restorable teeth, mandibular anteriors were retracted immediately to resolve anterior cross bite. After good anterior relationship was achieved, two anterior TADs were placed between #27 and #28 and between #21 and #20. By using two TADs as anchorage, #31, 32, and #17 were protracted until implant space for #29 and #19 were adequate. Absolute anchorage with TADs allowed maintaining good anterior relationship while protracting mandibular molars efficiently and effectively. I would like to thank Dr. Brian Payne for his supervision and guidance with this case. I would also like to thank my patient, Evelyn, for being incredibly compliant with her treatment and appointments.
