Advanced Science, EarlyView.Here, a decision‐making mechanism underlying mechanical adaptation is demonstrated. This study demonstrates that cellular adaptation to mechanical stress can be induced by applying low‐amplitude stretch to cells. When the stretch reaches a critical amplitude threshold, it triggers Ca2⁺‐dependent positive feedback, which induces cholesterol efflux and ...

A clinical comparison of the rate of maxillary canine retraction into healed and recent extraction sites—a pilot study [PDF]
, 2017 The rate of movement of the maxillary canines into the healed or recent extraction alveolus of the first premolar was measured in 22 patients aged 10-27 years. On one side of the dental arch, the first premolar was extracted.

Orthodontic-surgical treatment of class III malocclusion with mandibular asymmetry [PDF]
, 2011 Class III skeletal malocclusion may present several etiologies, among which maxillary deficiency is the most frequent. Bone discrepancy may have an unfavorable impact on esthetics, which is frequently aggravated by the presence of accentuated facial ...

Advanced Science, EarlyView.Orthodontic relapse persists as a 120‐year challenge, as traditional retainers fail to remodel tissue, causing lifelong dependence. This study demonstrates a flexible magnetoelectric retainer (FMOR) enabling wireless periodontal remodeling. FMOR cues shift periodontal ligament cell (PDLC) paracrine signaling, promoting M2 macrophages, osteogenic ...

Advanced Science, EarlyView.Lysosomal redistribution occurs via extracellular vesicles in multi‐stem cell aggregates and controls iron homeostasis for safeguarding cell aggregation. These cell aggregate‐released extracellular vesicles (CA‐EVs) rescue lysosomal impairments and exert anti‐ferroptosis effects in recipient irradiated endothelial cells.

Abnormal mandibular growth and the condylar cartilage [PDF]
, 2017 Deviations in the growth of the mandibular condyle can affect both the functional occlusion and the aesthetic appearance of the face. The reasons for these growth deviations are numerous and often entail complex sequences of malfunction at the cellular ...
