“…[12][13][14] Second, excessive lingual inclination of the lower anterior teeth might result in root exposure and periodontal fenestration during distalization. 15 Thus, periodontal flapping and bone grafting might be needed in the anterior and edentulous regions. Third, clockwise rotation of the mandible should be avoided, as it would aggravate the open bite and increase chin retrusion, although it would be helpful for correction of the anterior crossbite.…”

Treatment of hyperdivergent skeletal Class III malocclusion is challenging for orthodontists, and orthognathic-orthodontic treatment is usually required. This report presents the successful nonsurgical treatment of a 20-year-old man who had a skeletal Class III malocclusion with anterior open bite, anterior and posterior crossbite, hyperdivergent growth pattern, steep occlusal plane, early loss of three first molars, and an uncommon convex profile with a retruded chin. An orthodontic camouflage treatment plan was chosen based on the etiology and the patient's complaints. Tooth #37 was extracted. Miniscrews were used for uprighting and intruding of the lower molars, distalization of the lower dentition, and flattening of the occlusal plane. After 34 months of active treatment, Class I relationships, proper anterior overjet and overbite, flat occlusal plane, and an esthetic facial profile were achieved. The results demonstrated that the biomechanics involved in the nonsurgical treatment assisted with miniscrews to distalize the mandibular dentition and flatten the occlusal plane while keeping the mandibular plane stable was effective for treating this hyperdivergent skeletal Class III patient with a convex profile and anterior open bite.

“…In addition, revascularisation of chin grafts has been observed to be more rapid compared to other thicker grafts. [1][2][3][4][5][6][7][8][9][10] The relevance of the autologous chin graft is supported by its role as a fast, safe and reliable solution, with the additional advantage of avoiding immunological rejection due to its own origin. The scientific literature highlights its superior efficacy and prognosis compared to other types of grafts, such as allografts, xenografts, alloplasts or synthetics.…”

“…Hence, the gingival graft procedure is the current "gold standard" for the treatment [1]. However, this approach has various drawbacks such as donor-site damage, limited palatal mucosal tissue, and poor postoperative outcome [2][3][4]. Gingival regeneration is a complex developmental process, which involves the use of growth factors to establish a fully functional vascular microenvironment for tissue survival [5].…”

Although concentrated growth factor (CGF) is known to promote gingival regeneration and improve the outcomes of clinical treatment, the mechanisms underlying its effects remain unknown. Therefore, this study aimed to elucidate the effects of CGF on gingival thickening. To this end, gingival mesenchymal stem cells (GMSCs) were treated with different concentrations of CGF, and the effects of CGF on cell proliferation and migration; collagen-1 (Col-1), fibronectin (FN), vascular endothelial growth factor (VEGF), and angiopoietin-1 (Ang-1) expression; and the AKT, Wnt/b-catenin, and Yes-associated protein (YAP) signalling pathways were investigated. The effects of CGF in vivo were also investigated in a rat buccal gingival injection model. GMSCs cultured with CGF showed improved cell proliferation and migration. Moreover, CGF treatment improved the levels of FN, Col-1, VEGF, and ANG-1. These effects of CGF were mediated by the AKT/Wnt and YAP pathways, with the AKT pathway possibly functioning upstream of the Wnt/b-catenin and YAP pathways. YAP was also shown to be overexpressed in the in vivo model. Thus, CGF can promote gingival regeneration, and YAP transport into the nucleus may be a key factor underlying this activity, which provides a novel perspective for gingival regeneration and further promotion of the clinical application of CGF.
