Periodontal considerations during orthodontic intrusion and extrusion in healthy and reduced periodontium

Periodontology 2000, EarlyView.
Abstract In patients with advanced periodontal disease, pathological tooth migration may occur, which may require subsequent orthodontic treatment for both aesthetic and functional purposes. When planning orthodontic treatment mechanics, intrusive or extrusive forces are frequently indicated.

Reviewing the benefits and clinical outcomes of oral fibroblasts over mesenchymal stem cells for repairing periodontal defects during or after orthodontic tooth movement

Periodontology 2000, EarlyView.
Abstract Orthodontic therapy applies forces to teeth, causing an inflammatory reaction in the periodontal ligament. This is repaired by remodeling of the periodontium, allowing tooth displacement. Although orthodontic therapy is mostly initiated during childhood and adolescence, the number of adults seeking this treatment is increasing as our society's

Orthodontic management of uneven gingival margins in patients with healthy or reduced periodontium to improve smile aesthetics

Periodontology 2000, EarlyView.
Abstract Uneven gingival margins may cause visible asymmetries during smiling and may reflect alterations in the tooth shape and morphology, particularly in cases requiring restorative procedures. Despite being perceived as a minor health condition, presence of uneven gingival margins usually impacts the smile aesthetics and could affect the individual'

30 years of enamel matrix derivative: Mimicking tooth development as a clinical concept

Periodontology 2000, EarlyView.
Abstract The use of growth factors (GFs) has become a cornerstone of modern regenerative periodontology. While the extent to which GFs enhance tissue regeneration compared to other biomaterials was initially uncertain, it is now well established that GFs play a critical role in the regeneration of various tissue types.
