Definitions

  • the present descriptive report refers to a utility model application for a screw/pin to be used for anchorage in the implantation of dental prostheses.
  • BR 102014021198-5 entitled “IMPLANT DENTAL IMPROVEMENT”, which claims a pin for implant that has concave-shaped threads at its ends and gradual diameter reduction in the central part of its body, which promotes a space between the pin and the patient's bone mass, in order to allow the accumulation of blood clot and protein secretions responsible for the prompt restoration and healing of the injured region;
  • the inventor notes that the pins found on the market, as well as the one mentioned above, because they have smooth parts do not offer pressure dissipation of the force at the time of mastication in the entire bone area around the implant.
  • the exposed regions of the heads (or extremities upper) where the implants are inserted extend beyond the bone, which can cause implant fixation problems or present vulnerable spaces for the accumulation of bacteria.

  • Figure 6 top view of the bone implant screw
  • Figure 7 inferior view of the bone implant screw
  • Figure 8 illustrative view of the bone implant screw introduced into the bone, having received the threading of a dental implant.
  • Said screw (1) is formed by a cylindrical body equipped with threads (2) along its entire length, from one end to the other.
  • the upper end of the screw (1) has a recessed central section (3), with a slight inclination, ending in a hexagonal socket (4), also recessed, whose center projects an internal threaded hole (5).
  • the opposite, lower end of the bolt body (1) is chamfered (6).
  • the lower middle portion of the screw body (1), below its central point, is pierced by a hole (7), whose ends are directed downwards, inclined in opposite directions, tearing the screw body (1) in two grooves. flow (8) opposed.
  • the cylindrical body of the screw (1) has a shape similar to a pin, as it is straight and not conical, having approximately 10mm in length and 4mm in diameter.
  • the lower beveled end (6) of the screw (1) has an angle of approximately 170° inwards, towards the center, creating a kind of tip that gradually thins the threads (2) .
  • the hole (7) that goes through the body of the screw (1) is approximately 2/3 of the latter's diameter.
  • the grooves (8) extend from the opposite ends of the hole (7) and descend in inclination, but in a rectilinear way, without following the curve of the body, until exceeding the chamfered lower end (6), which is torn by these, forming a channel for directing the scraped material towards the hole (7).
  • the grooves (8) tear the body of the screw (1) as well as its threads (2), as in a drill, exposing by its edges a kind of saw provided by the contours of said threads (two).
  • the threads of the thread (2) are square or truncated.
  • the screw (1) is limited by its main configurations, but these do not restrict small variations, which can be applied without mischaracterizing the invention, such as, for example, different fittings for prostheses at the upper end of the screw (1) ); different measurements and angulation of the threads (2); different angles of the grooves (8); different measures of the body of the screw (1) and diameter of the hole (7) through; be used in association with bone fixation plates and osteogenic distractors.
  • the screw (1) as main technical effects, can be cited:
  • the fully threaded body of the screw (1) allows its tight introduction, up to its upper end, without the need to leave the head exposed beyond the bone (O), which facilitates the introduction, adjustment and seating of the implant (I);
  • the internal threaded hole (5) allows a tight fixation of the implant (I) by its thread (R);
  • the chamfered lower end (6) appears as a kind of tip that gradually thins the threads (2), creating a support for the beginning of the bone perforation, which proceeds without the need for previous perforation;
  • the grooves (8) whose edges appear like a saw, help to scrape the bone, opening the way and creating the fillets in the bone for the introduction of the screw (1);
  • the through hole (7) determines both the beginning of the grooves (8) and an internal space for the settlement of the bone material and anchorage in the osseointegration process, promoting there a kind of autogenous graft for an accelerated bone healing, ensuring good fixation of the screw (1) during the healing process;
  • the square or truncated shape of the threads (2) have a better anchorage inside the bone, with a greater area of contact, allowing better bone healing;

Abstract

L'invention concerne une vis (1) pour fixation osseuse et implants osseux de prothèses dans des procédés odontologiques. Cette vis est formée par un corps cylindrique doté de filetages (2) sur toute sa longueur, dont l'extrémité supérieure de vissage et mise en prise de l'implant est rentrante, et dont l'extrémité opposée, inférieure, est chanfreinée (6). La partie médiane inférieure du corps de la vis (1) est traversée par un trou (7), dont les extrémités sont orientées vers le bas, inclinées dans des directions contraires, divisant le corps de la vis (1) et ses filetages (2) en deux sillons (8) opposés.
