Comprehensive treatment for severe periodontitis with pathologic tooth migration-related bimaxillary protrusion: A case report with 3-year follow-up.

Background And Overview: Patients with severe periodontitis often experience pathologic tooth migration (PTM), which impairs esthetics and leads to occlusal disharmony (for example, premature contacts and traumatic occlusion) that can further exacerbate periodontitis. The authors describe a patient who exhibited severe periodontitis with PTM-related bimaxillary protrusion. This report includes 3-year clinical outcomes after periodontal regenerative therapy, implant-anchored orthodontic therapy, and implant prosthodontics intended to achieve both functional and esthetic improvements.

Interdisciplinary therapy for severe periodontitis with Angle Class II Division 1 malocclusion: A case report with 7-year follow-up.

Background And Overview: Previous studies have suggested that occlusal discrepancy is a risk factor contributing to periodontal disease. Occlusal discrepancy could increase the risk of developing infrabony defects. The authors present a case of a patient with severe periodontitis who exhibited many infrabony defects in the molar region due to malocclusion-induced trauma.

Fas/S1P crosstalk via NF-κB activation in osteoclasts controls subchondral bone remodeling in murine TMJ arthritis.

Enhanced turnover of subchondral trabecular bone is a hallmark of rheumatoid arthritis (RA) and it results from an imbalance between bone resorption and bone formation activities. To investigate the formation and activation of osteoclasts which mediate bone resorption, a Fas-deficient MRL/lpr mouse model which spontaneously develops autoimmune arthritis and exhibits decreased bone mass was studied. Various assays were performed on subchondral trabecular bone of the temporomandibular joint (TMJ) from MRL/lpr mice and MRL+/+ mice.

Roles of hypoxia inducible factor-1α in the temporomandibular joint.

Objective: Temporomandibular joint osteoarthritis (TMJ-OA) is a degenerative disease characterized by permanent cartilage loss. Articular cartilage is maintained in a low-oxygen environment. The chondrocyte response to hypoxic conditions involves expression of hypoxia inducible factor 1α (HIF-1α), which induces chondrocytes to increase expression of vascular endothelial growth factor (VEGF).

Correction: Rebamipide Attenuates Mandibular Condylar Degeneration in a Murine Model of TMJ-OA by Mediating a Chondroprotective Effect and by Downregulating RANKL-Mediated Osteoclastogenesis.
