Abstract: La presente invención tiene por objeto la obtención de biomateriales compuestos nanoestructurados y bioactivos para impresión 3D de dispositivos médicos, formados por mezclas biocompatibles de polímeros derivados del Dimetacrilato de Uretano (UDMA), Tetrahidrofurfuril Metacrilato (THFMA), Metacrilato de Metilo (MMA), Polimetilmetacrilato de Metilo (PMMA), 2-hidroxietil metacrilato (HEMA), Alcohol vinílico (AV), alcohol polivinilíco (APV), Acido poliláctico (APL), Acido poliglicólico (APG), Acetato de vinilo (VAc) y acetato de polivinilo (PVAc) combinados con fotoiniciadores y mezclas de nano y miicropartículas de compuestos inorgánicos de hidroxi-carbonato-fosfatos de calcio y óxido de titanio dopados con nanotubos de carbono multicapa y grafeno. Las mezclas resultantes son imprimibles en 3D dada su composición y naturaleza, permitiendo la reproducción exacta de imágenes sólidas virtuales de partes de tejidos y órganos. Las mismas pueden ser confeccionadas mediante el diseño asistido por ordenador o generadas a partir de imágenes médicas como TAC, IRMN y otras. Los polímeros sintetizados tienen propiedades mecánicas adecuadas y son biocompatibles, lo que permite su utilización en la fabricación de dispositivos médicos implantables.

Abstract: Apparatus and methods for adjustably retaining an oral appliance to an abutment assembly are disclosed. In one variation, a securement apparatus can comprise a sleeve having a sleeve frame and a number of locking flaps. The sleeve can define a lumen therethrough for positioning upon an abutment assembly. The locking flaps can have varying length dimensions and can project radially inward or outward relative to the sleeve frame. The outward flaps can lock against surface features defined along an inner surface of a coping coupled to the oral appliance and the inward flaps can lock against surface features defined along a portion of the abutment assembly. The sleeve can release the oral appliance from the abutment assembly when the locking flaps of the sleeve are actuated by an actuation unit.
