Abstract
Description
L'invention se rapporte à un dispositif visant à un positionnement spatial précis des implants dentaires. Un implant dentaire est une racine artificielle placée dans l'os destinée à remplacer de façon fixe ou amovible une ou plusieurs dents absentes. La mise en place des implants dentaires est réalisée par forage osseux au moyen de forets calibrés de différents diamètres avec pour objectif d'obtenir un logement dans l'os dont le volume est en rapport avec la forme, le diamètre et io la longueur de l'implant utilisé . La localisation précise du ou des implants est essentielle. En effet, tel une fondation sous une maison, il est souhaitable d'avoir le ou les implants dentaires à un emplacement précis (en général, à la verticale) de la ou des dents artificielles 15 que l'on souhaite construire pour des raisons évidentes d'hygiène, d'équilibre et de répartition des forces, de volume osseux suffisant autour des implants, de faisabilité de l'édifice prothétique et d'esthétique. Les systèmes actuels passent, en général, par l'utilisation 20 d'une fraise boule de petit diamètre (fig.1) avec laquelle un pointage est réalisé dans l'os. The invention relates to a device for precise spatial positioning of dental implants. A dental implant is an artificial root placed in the bone to replace fixed or removable one or more missing teeth. Implantation of the dental implants is performed by bone drilling using calibrated drills of different diameters with the objective of obtaining a housing in the bone whose volume is related to the shape, the diameter and the length of the implant. implant used. The precise location of the implant (s) is essential. Indeed, as a foundation under a house, it is desirable to have the dental implant or implants at a specific location (generally, vertically) of the artificial tooth or teeth 15 that one wishes to build for obvious reasons hygiene, balance and distribution of forces, sufficient bone volume around the implants, feasibility of the prosthetic building and aesthetics. Current systems generally involve the use of a small-diameter ball mill (FIG. 1) with which a pointing is made in the bone.
On peut alors évaluer la distance entre : • Les dents existantes et le centre du ou des futurs implants (f ig.2), • La distance entre les centres des futurs implants 5 (fig.3). Cette technique demeure toutefois imprécise pour plusieurs raisons : • Localiser le centre de l'implant ne donne aucune ~o information sur le diamètre final de l'implant, • Les implants dentaires existent dans différents diamètres et il est difficile de projeter le diamètre final des différents implants. ls Le dispositif ob jet de l'invention a pour but : • de localiser et de visualiser le diamètre du ou des implants choisi à un stade précoce de la mise en place quel que soit le diamètre du ou des implants choisi, • de valider la distance entre le ou les implants et la ou 20 les dents résiduelles contigües du secteur à implanter, • de valider la distance entre les implants quel que soit le diamètre des implants choisi. L'invention et sa mise en oeuvre apparaîtront plus clairement à l'aide de la description qui va suivre, faite en référence aux dessins annexés illustrant uniquement à titre d'exemple quelques situations cliniques d'utilisation. Description de l'invention lo Foret dentaire (fig.4) d'une forme telle qu'il présente : 1. Une tige (1) d'un diamètre adapté à un usage à l'aide d'instruments rotatifs dentaires et/ou implantaires classiques. Celle-ci pourra être de différentes longueurs afin de pouvoir être utilisée dans différentes 15 situations cliniques, 2. un élément de pointage (2) en son centre visant à valider un point de forage (centre de l'implant souhaité) et à stabiliser le foret dans l'espace, 3. une périphérie ressemblant à une scie cloche (3) dont 20 les bords sont tranchants visant à faire un marquage osseux afin de visualiser le diamètre final de l'implant souhaité. Cet instrument sera décliné avec différents diamètres de scie cloche pour être adapté au diamètre du ou des implants que l'on envisage de poser. Les matériaux utilisés seront compatibles avec 5 • l'usinage de l'os, • les procédés actuels de stérilisation We can then evaluate the distance between: • The existing teeth and the center of the future implant (s) (fig.2), • The distance between the centers of the future implants 5 (fig.3). However, this technique remains imprecise for several reasons: • Locating the center of the implant gives no ~ o information on the final diameter of the implant, • Dental implants exist in different diameters and it is difficult to project the final diameter of the implants. different implants. The aim of the objective device of the invention is: to locate and visualize the diameter of the implant (s) selected at an early stage of placement regardless of the diameter of the implant (s) chosen, to validate the distance between the implant (s) and the adjacent residual tooth (s) of the sector to implant, • to validate the distance between the implants irrespective of the diameter of the implants chosen. The invention and its implementation will appear more clearly with the aid of the description which follows, made with reference to the accompanying drawings illustrating only by way of example some clinical situations of use. DESCRIPTION OF THE INVENTION The dental drill (FIG. 4) has a shape such that it has: 1. A rod (1) of a diameter suitable for use with dental rotary instruments and / or classical implant. This may be of different lengths in order to be used in different clinical situations, 2. a pointing element (2) at its center to validate a drilling point (center of the desired implant) and to stabilize the drill in the space, 3. a periphery resembling a hole saw (3) whose edges are sharp for bone marking in order to visualize the final diameter of the desired implant. This instrument will be declined with different bell saw diameters to be adapted to the diameter of the implant or implants that are planned to pose. The materials used will be compatible with 5 • the machining of the bone, • the current processes of sterilization
On peut ainsi dessiner dans l'os l'emplacement des futurs implants (f ig.5). On peut s'assurer que : io • le diamètre choisis est judicieux, • la position du ou des implants est adaptée au volume osseux disponible, • l'espacement entre le ou les implants et la ou les dents résiduelles est adéquat (f ig.6), 15 • l'espacement entre les implants est adéquat (fig.7et8), et ce à un stade précoce de l'intervention chirurgicale sans avoir réalisé le forage complet et invasif du logement implantaire. 20 It is thus possible to draw in the bone the location of the future implants (f ig.5). It can be ensured that: • the chosen diameter is judicious, • the position of the implant (s) is adapted to the available bone volume, • the spacing between the implant (s) and the residual tooth (s) is adequate (Fig. 6), 15 • the spacing between the implants is adequate (fig.7 and 8), and this at an early stage of the surgical procedure without having completed the complete and invasive drilling of the implant housing. 20
