Definitions

  • the present invention patent application consists, as indicated in its statement, in a "PERFECTED DENTAL IMPLANT", whose new construction, conformation and design characteristics fulfill the mission for which it has been specifically projected with maximum safety and efficiency.
  • the implant object of the invention is designed with the aim of replacing missing teeth, recovering masticatory, phonatory, aesthetic functions and maintaining a high degree of stomatognathic system functionality.
  • the state of the art of the plantology allows the replacement of dental pieces by means of threaded and impacted implants to which they are attached, if necessary, the straight or angled transepithelial emergent (if the implant has been inclined in the bone bed that is work for placement) to end the placement of the prosthesis, either with thread retention or by joining between surfaces with special dental cement.
  • the first type it is a cylindrical implant of pure titanium or coated with a layer of hydroxyapatite or titanium dioxide, of equal diameter and slightly greater than the bone bed practiced, being initially stabilized by slight friction when introduced or impacted.
  • the second requirement of anti-rotational stability is achieved by generating channels in the cylindrical surface where, when a bone is formed, it prevents, once subjected to the actions, a connection side to the rest of the components (emergent, prostheses, due to the rotational force that is generates by tapping the pop-up and the definitive retaining screw of the prosthesis) and on the other to the functional actions of masticatory loading; the rotation or mobility of the implant.
  • Other systems instead of channels employ perforations perpendicular to the surface in the lower zone, leaving spaces where bone formation and growth facilitates anti-rotational stability.
  • the implant In relation to the second type of implants, threaded, it is also a cylindrical implant, but on its surface a thread of different pitch and shape is worked from the intermediate to the lower zone, leaving the upper third or coronal area of the smooth implant, of this way when the thread reaches the lower area and once the bone bed of smaller diameter has been carved, the implant is threaded being initially stabilized.
  • notches are carved in the lower area and the implant is perforated perpendicularly, so that when the bone grows it prevents rotation.
  • a harmonic design of the body and the implant head has been obtained, following a proportion in its surface areas and in its geometry, to avoid crown-root discrepancies and achieve diameters in line with the final prosthesis.
  • the height of the transepithelial abutments can be reduced, in relation to the retentive stop of the clinical retentive screws of the definitive prosthesis, due to the reduced height of the internal and external hexagons.
  • the fixing installation technique in the The mouth is surgically similar to that of the other systems, being able to choose between a submerged or non-submerged technique (when the implant is covered by soft tissue or not).
  • the invention relates to a piece for dental implants, whose design based on a Single body is formed by a conical head that extends into a cylindrical zone, which in turn extends inferiorly into an apical tip, also conical.
  • a substantially truncated conical hole is provided, which in addition to allowing greater self-retention force, ends in hexagonal areas that prevent and reduce the relative movement of rotation between the implant and the prosthetic components.
  • Figure ns 1 is a partially sectioned front elevation view of the improved dental implant (10).
  • Figure ns 2 is a top plan view of the implant (10).
  • the implant (10) consists of three clearly defined and formally distinct zones: the conical head (24) , the cylindrical body (16) and the conical apical tip (17).
  • the conical head (24) has in its upper zone a conical recess (11) which extends downwards according to a step (12), which in turn extends into a chamfered vertex (13).

Abstract

L'invention concerne un implant dentaire perfectionné à connexion multiple, constitué d'une broche en matière biocompatible, comportant une tête conique (24), une zone cylindrique (22) et une pointe conique (17) filetée destinée à l'os cortical. Un prisme hexagonal (11) a été usiné dans cet implant, depuis son extrémité inférieure jusqu'au début de la tête (24) au niveau de son extrémité supérieure. Dans la base supérieure de ce prisme hexagonal a été pratiqué un orifice tronconique (21), au bout duquel se trouve une cavité hexagonale (22), centrée sur l'axe de la pièce, sur la base inférieure de laquelle un évidement conique (23) et un taraudage (20) ont été usinés. Les arêtes supérieures de l'hexagone extérieur (11) et l'extrémité de la tête (24) ont été usinés de manière à présenter un profil conique, afin de faciliter l'accouplement avec les composants prothétiques associés à l'implant (10), lequel est destiné à remplacer des racines dentaires mortes.
