Por qué importa

Trabajo con 20 pacientes de mordida abierta esquelética que explica biológicamente por qué la mecánica de intrusión con miniplacas produce un efecto intrusivo real aunque las fuerzas aplicadas sean de inclinación. Con superposiciones tomográficas 3D antes y después, documenta remodelación ósea en crestas y apicales y una reabsorción radicular insignificante, un argumento clave a favor del anclaje con miniplacas frente a otros dispositivos.

Abstract original

Objective: Biologically explain some of the bone mechanisms involved in the intrusion, or intrusive effect, of teeth submitted to skeletal open bite correction using four miniplates. Methods: The results of dental intrusion were measured and compared in 3D reconstructions of cone beam computed tomography scans taken before and after treatment of 20 patients with skeletal open bite, aged between 18 and 59 years. Results: The results allow deducing that the compression and traction forces biologically promoted deformation or deflection of the osteocyte network that controls bone design, and these effects involved the external and internal surfaces of the bone, with the formation of new layers, including the cervical portion of the alveolar bone crest. The root resorptions caused by the use of miniplates were insignificant, due to the more homogeneous distribution of forces in the several teeth simultaneously involved.
