Definitions

  • the conventional procedure in oral rehabilitation with dental implants consists of the surgical placement of the dental implant, followed by a period of osteointegration of a few weeks, and only afterwards is the final ceramic or metal ceramic restoration manufactured.
  • the restoration can be placed immediately after surgery, but in this case the procedure is referred to as "immediate rehabilitation" and the restoration itself is provisional and made of acrylic resin.
  • the present device allows surgical guidance during the placement of the dental implant, with such precision that the final restoration of ceramic or metal ceramic material can be placed immediately after surgery, i.e. the clinician places the dental implant and the final restoration, which has been previously manufactured, immediately after surgery and in the same clinical session. Therefore, the patient receives in a single session the implant and the final restoration, thus saving several weeks.
  • the conventional procedure in oral -rehabilitation with dental implants consists of the surgical placement of the dental implant, followed by a period of osteointegration of a few weeks, and only afterwards is the final ceramic or metal ceramic restoration manufactured.
  • the restoration can be placed immediately after surgery, but in this case the procedure is referred to as "immediate rehabilitation" .
  • This immediate rehabilitation is provisional, i.e. the restoration remains in the oral cavity for a pre-established period of a few weeks or months, and it is made of acrylic. After this period of time, a final or permanent restoration is required, for which purpose another two or three sessions will be necessary.
  • This invention consists of two pieces that function together, guiding the dental implant surgery with such precision that the final restoration can be placed in the same clinical session, immediately after the placement of the dental implants.
  • These pieces are: - a dental implant carrier, built with a screw pitch exactly identical to that of the dental implant, but having a wider diameter; and - a guide for the dental implant carrier, also threaded in the same way, which will help to guide the carrier during the surgical procedure.
  • This dental implant carrier guide is stabilized in the mouth with the help of the neighbouring teeth and using high precision acrylic resin.
  • This set (acrylic and dental implant carrier guide) can also have its stability increased by the use of bone pins .
  • the drills used to prepare the bed of the implant are used in accordance with the axis and position of the dental implant carrier guide, which is stabilized in the mouth by using small metal sleeves which guide the functioning of these drills by fitting into the dental implant carrier guide. These sleeves have a handle which facilitates their use, and their inner and outer surfaces are unthreaded.
  • the implant can be placed as follows: the dental implant carrier and the implant to be placed are connected. This set is then connected to the motor/hand piece that will rotate it in order to place the dental implant .
  • the positioning of this set inside the dental implant carrier guide will be made through the upper occlusal access or laterally, through the lateral access.
  • the dental implant itself can be placed into the bone; it is essential that the guidance of the dental implant carrier by the dental implant carrier guide starts before the dental implant engages the bone. In this way, maximum precision is guaranteed.
  • the dental implant is thus guided into its final position by permanent contact between the dental implant carrier guide and the dental implant carrier, until the metal stop on the carrier touches the guide and thus halts the descent of the implant .
  • the whole set (dental implant carrier, dental implant carrier guide and high precision acrylic) is removed from the mouth and the dental implant remains in its predetermined position.

  • the dental implant carrier (1) connects to the dental implant (2) forming a single piece, as represented by (3) in the attached figures.
  • This connection between the carrier and the implant can be obtained in several ways, for example with a screw through a nut on the implant and a tap on the carrier, the nut/tap parts having any appropriate configuration (square, hexagonal, etc.)
  • This set consisting of the implant carrier (1) and the dental implant (2) , is placed in position (Fig. 3) inside the implant carrier guide (3) (Fig. 2) through its occlusal or lateral access.
  • the guide (3) is provided with a side window or opening (6) which allows the carrier/implant set to be placed laterally.
  • the implant carrier (1) is driven through the guide (3) during the descent using a rotational movement. This movement is maintained until the metal stop (7) of the implant carrier (1) touches the guide (3) .
  • the dental implant carrier guide (3) is stabilized in the mouth using the neighbouring teeth and high precision acryl ⁇ c resin; however, this whole set can also be fixed with the help of bone pins, thus increasing its stability.

Abstract

La présente invention concerne un dispositif de précision pour la mise en place d'implants dentaires, constitué d'un guide de précision chirurgical pour le placement d'implants dentaires, caractérisé par le fait qu'il comprend un porte-implant dentaire (1) ayant un pas de vis exactement identique à celui de l'implant dentaire (2) à mettre en place, et un guide/matrice (3), également fileté avec un pas de vis identique à celui de l'implant dentaire; dans ce guide de précision chirurgical, seul le filet (4) du porte-implant dentaire (1) entre en contact avec le filet du guide (3) du porte-implant afin de créer une zone ou surface de contact minimale entre les deux pièces, de sorte que la précision de ce système de guidage est suffisante pour permettre la mise en place de la restauration finale, dans un matériau de céramique ou métallo-céramique, immédiatement après une intervention chirurgicale et satisfaisant les niveaux d'ajustement connus dans les techniques classiques.
