[0032] FIG. 3 shows an exploded perspective view of the elements that make up the drilling guide of the present disclosure.

[0033] FIG. 4 shows an exploded perspective view of some of the elements of FIG. 3 according to a possible embodiment of the disclosure.

[0034] Lastly, FIG. 5 shows a schematic representation of the mouth of a patient in which the angle comprised between the vertical of the bone tissue plane and the axis angle towards the mesial is represented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0035] As may be seen in FIGS. 1 to 5, in which a preferred embodiment of the disclosure is shown, the guide for planning and drilling dental implants is structured such that it comprises: [0036] A support (1);

[0037] A plate (2) in the form of a horizontal sheet that is fastened on the support (1) but may move and be detached with respect to it, and is therefore interchangeable and which comprises an angle at at least one of the ends thereof.

[0038] Furthermore, according to a possible embodiment of the disclosure, said plate (2) comprises, at at least one of the ends thereof, a means for regulating the angle (not shown) such that different angles for drilling the bone tissue may be selected using a single plate, thus removing the need to use different plates for each one of the angles. Said means for regulating the angle may be formed by, for example, a hinge or similar that, alongside the blocking means, enable the position of said end of the plate to be positioned and fixed at will or in predetermined positions and angles α, from 0° to 60°. [0039] A guide body (3) located at the angled end of the plate (2) for correctly guiding said drill bit or drill responsible for perforating the bone tissue with the appropriate angle and depth.

[0040] According to a possible practical embodiment shown in the figures, said guide body (3) is made up of a cylindrical body that has a wide radial slot to facilitate the insertion of the drill in the case of compromised openings.

[0041] Furthermore, according to another possible embodiment of the disclosure, said guide body (3) may be detached and is interchangeable, thus enabling it to be substituted for another depending on the diameter and length of the drill, equipping the guide of the disclosure with even greater versatility. [0042] A rod (4), preferably cylindrical, with one upper end and one lower end, wherein: [0043] The upper end is joined to the support (1) through rotation means (5) that enable the relative movement between both.

[0044] According to a possible practical embodiment, shown in FIG. 4, said rotation means (5) are formed by a ball-shaped extremity that cooperates with a spherical cavity in the support (1) such that said support (1) may rotate freely on the upper end of the rod (4), facilitating the placement and orientation thereof. [0045] The lower end is inserted in the bone tissue of the mouth of the patient, fastening thereto due to retention means (6).

[0046] According to a possible practical embodiment of the disclosure shown in FIG. 4, said retention means (6) are constituted by a conical section that increases in diameter as it moves away from the lower end, such that adjustment between the rod (4) and the bone tissue is carried out by friction.

[0047] According to another possible embodiment, said conical section may also comprise a certain surface roughness obtained by means of any method known with the aim of improving the fastening between the rod (4) and bone tissue.

[0048] Furthermore, and as may be seen in the figures, especially in numbers 1 and 3, the plate (2) comprises horizontal movement means (7) that enable the distance between the rod (4) and the guide body (3) located at the angled end of said plate (2) to be varied.

[0049] According to a possible embodiment of the disclosure shown in said figures, the horizontal movement means (7) are formed by a rail or groove through which the assembly formed by the support (1) and the rod (4) may be moved. Specifically, in said exemplary embodiment, the movement is achieved due to the effects of a tightening element (10) that fastens the support (1) to the plate (2) by means of a second rod (12) or similar that is inserted through said rail in a hole (13) in the upper portion of the support (1).

[0050] Furthermore, it is possible to facilitate the insertion of the drill, in the cases where the openings are compromised, due to said rail or groove, which runs to the guide body (3). In other words, the rail or groove therefore has a dual function, constituting of, on the one hand, horizontal movement means (7) and, on the other hand, constituting a hole to facilitate the insertion of the drill when necessary.

[0051] Furthermore, as may be seen in the figures, the support (1) has a lower body (8) that serves to house both the second rod (12) of the tightening element (10) and the upper end of the rod (4), thus meaning that in the case in which said upper end has a ball, it has a complementary spherical cavity.

[0052] Moreover, according to a possible practical embodiment shown in FIGS. 1 and 3, the plate (2) has position markers (11) such that the surgeon may have a reference of the relative movement between the support (1) and said plate (2).

[0053] Nevertheless, according to a possible practical embodiment of the disclosure, shown in FIG. 4, said upper end of the rod (4) may be joined to the support (1) by means of an intermediate element (9) that is housed in the lower body (8) of said support (1).

[0054] Lastly, the guide of the disclosure is embodied with any material that fulfils the mechanical and biocompatibility requirements and which may be sterilised, such as metals like stainless steel or titanium, plastics, etc.
