A 34-year-old male patient visited our department on May 25, 2009, with chief complaints of anterior teeth separating and discomfort in the gums. As described above, clinical and radiographic examinations were performed ( and , ). He was diagnosed with an endo-perio lesion due to loss of tooth vitality and the pathologic tooth migration of 21. The treatment plan was periodontal therapy to eliminate causes, tooth movement of 11 and 21, and prosthodontic treatment.\nand are clinical photographs of the front side and the occlusal plane after the periodontal treatment. As in case I, clinical photographs at the front side and occlusal plane views were taken after fabricating clear aligner on the cast and applying the device ( and ). and are clinical photographs of the front side and occlusal plane views after 3 weeks of using the new appliance. A new appliance was applied again after 6 weeks ( and ). Prosthodontic treatment was performed as planned ( and ). After completing prosthodontic treatment, radiographs were taken for radiographic evaluation ().\nTo measure the results of the treatment, PPD, CAL, GR, and mobility were measured after treatment. GR and CAL decreased about 1 mm compared to the first visit, and mobility decreased slightly ().\nIn radiographs, the vertical and horizontal dimensions were measured after treatment (). Radiographically, the size of infrabony defects decreased 2.1 mm vertically and 0.7 mm horizontally. However, as in case I, actual bone filling in the lesions could not be determined based on the radiographic view alone.
