Background/purpose: The inconclusive issue of teeth treated with periodontal regeneration and combine with orthodontic tooth movement warrants further investigation and clinical experiences. The objectives of this retrospective clinical study were to analyze periodontal health and stability of teeth with periodontitis under the periodontal regeneration and orthodontic treatment and the timing and direction of orthodontic movement intervention.
Methods: A total of 41 infrabony defect sites (21 patients, from 23 to 66 years-old;) receiving interdisciplinary treatment in the past ten years (from 2008 to 2019) at National Taiwan University Hospital were selected. The defects were grouped into subgroups depending on orthodontic tooth movement timing and directions after periodontal regeneration surgery. The mean baseline probing depth (PD), baseline clinical attachment level (CAL), PD reduction and CAL gain after interdisciplinary treatment were statistically analyzed.
Results: Both early and late orthodontic tooth movement groups showed improvement in PD reduction and CAL gain, and the early orthodontic tooth movement group showed slightly better clinical outcome without statistically significant compared with the late orthodontic tooth movement group. It showed more PD reduction and CAL gain in into-defect group, and it's statistically significant compared to off-defect and alignment groups. No statistically significant in the clinical outcome regarding of protocols (guided tissue regeneration, enamel matrix derivatives or grafting with open flap debridement).
Conclusion: Our study revealed that teeth can be successfully moved following regenerative surgery with good periodontal improvement. Moreover, early orthodontic tooth movement may not jeopardize the regenerative effect, and may have the potential to improve the overall efficiency of the treatment. Besides, moving into the defects can benefit more in probing depth reduction and clinical attachment level gain.

Objective: This study aimed to evaluate the effects of attachment design on maxillary molar distalization and simultaneous expansion during distalization, and the influence of third molars on distalization in the clear aligner technique using the finite element method.
Methods: Six models were created to evaluate three different attachment designs on the second molars. Model I: employed a vertical rectangular attachment; Model II: used a vertical rectangular attachment with the presence of the third molar; Model III: used a combined semi-elliptical attachment; and Model IV: featured an opposed semi-elliptical attachment with buccal and palatal components.

Objective: Miniscrews are commonly utilized as temporary anchorage devices (TADs) in cases of maxillary protrusion and premolar extraction. This study aimed to investigate the effects and potential side effects of two conventional miniscrew configurations on the maxillary incisors.
Methods: Eighty-two adult patients with maxillary dentoalveolar protrusion who had undergone bilateral first premolar extraction were retrospectively divided into three groups: non-TAD, two posterior miniscrews only (P-TADs), and two anterior and two posterior miniscrews combined (AP-TADs).

Objective: This study aimed to evaluate bone remodeling in gingival crevicular fluid (GCF) during canine distalization in obese individuals and compare it to that in normal-weight individuals. Additionally, the orthodontic tooth movement rates of obese individuals were measured and compared with those of normal-weight individuals.
Methods: Thirty-six patients (18 obese and 18 normal-weight) aged 12-18 years who were candidates for maxillary first premolar extraction for Angle Class II malocclusion were included in the study.

An 18-year-old Chinese woman presented with chief complaints of crowded teeth and mild mandibular prognathism. Clinical and imaging examinations revealed a concave profile, a protruded chin, increased lower anterior facial height mild, skeletal Class III and Angle's Class III malocclusion, with anterior crossbites, and crowded teeth. Extraction camouflaged therapy combined with miniscrews skeletal anchorage was employed to relieve crowding and retract the mandibular anterior teeth.
