Definitions

  • the present invention is a set of instruments from the Civil Engineering area, evidenced by the Physical properties, notably developed to act as a foundation, maintainer and protector, aiming at full adaptation to the oral environment, according to the professional's expectation and seeking harmony of the user, in this case the patient.
  • This invention is a composite and complex structure for dental prostheses, the purpose of which is to improve resistance in treating edentulous patients.
  • Implantology is a process of oral rehabilitation, advocated in the mid 1980s by prof. Branemark, aiming to create an anchor system for fixed prostheses through titanium implants. After the creation of the surgical shop with drills, the implant is threaded, creating full intimacy and adaptation. After osseointegration, the subsequent phase is the placement of a crown to replace the missing dental element. This can be individualized, where each implant receives its respective crown, or otherwise, some implants receive more teeth, but must be joined to withstand the chewing efforts.
  • Biocompatibility refers to the compatibility and relationship between a given material and the biological environment in which it must remain. In the case of Implantology, biocompatibility depends on the interactions between implants and adjacent tissues, and may vary between individuals and according to the region of the mouth.
  • Bioceramics as a substitute for natural teeth, has 4000 years of history, being verified in the Mayan civilization (1,000 BC to 900 AD), in skulls, showing the replacement of missing teeth by substitutes carved in mother of pearl. Its clinical practice in dentistry, however, only began in the eighteenth century, with the use of porcelain in dental crowns. With the advances made in the In the twentieth century, in processing technology, ceramic materials began to perform better mechanically, intensifying their applications in the fields of medicine and dentistry.

  • Yttrium oxide stands out as the most widely used material for zirconia stabilization. Polyethylene stabilized by itria results in a ceramic material of high toughness. This stabilization can contain the crack propagation, generating a compression in the area, with opposite force to the crack propagation, preventing its fracture.
  • force is a quantity, measured in Libras or Newton, whose definition includes not only the amount but also the direction in which the force is acting, since a given amount of force acting vertically on a Implant, for example, does not exert the same effect as a force acting in a lateral direction.

Abstract

La présente demande de brevet d'invention concerne un squelette pour prothèses dentaires, pouvant permettant de dissiper les forces masticatoires et de réduire la tension sur l'ensemble prothétique, soit le revêtement, la structure, le pilier et l'os alvéolaire, offrant ainsi une fiabilité et un longévité accrues pour les travaux de restauration buccale. Cet effet est obtenu par modelage du squelette (E) en courbe descendante par la cavité occlusale (Oc) jusqu'à l'appui (A), contournant le tissu mou ou la gencive (T) sur 360 degrés, se terminant au niveau de la limite latérale (AI) et formant une base concave appropriée pour le parfait emboîtement du revêtement (R) esthétique, fonctionnel et résistant.
