DESCRIPTION

VARIANT OF THE PRECISION BIPHASIC GUIDE AND ITS METHOD TO FIX IN A LOW HEIGHT MAXILLARY BONE USING A TRIPOD WITH A SHORT DENTAL IMPLANT FUNCTION SURGICAL GUIDE

TECHNICAL SECTOR

The present invention belongs to the field of dental implantology.

The object of the present invention is a variant of the precision biphasic guide and its method for fixing a tripod with a short dental implant function in a low jaw bone using a surgical guide, which provides a comfortable, fast and safe way to fix a tripod, which can support the load of a prosthesis, in wide but low areas of the jawbone avoiding regenerative surgeries such as sinus lift or en bloc jaw reconstructions.

BACKGROUND OF THE INVENTION

Short dental implants are relatively recent implants. These are wide dental implants, typically greater than 5MM wide and short, typically up to 5MM high. These implants are aimed at short and wide areas of bone but, although presenting an acceptable osseointegration, they are very unpredictable when placing a prosthetic load on them, which significantly reduces their use. The Roxolid® SLActive® implant with short Loxim ™ from Straumann and the Anyridge® short implants from IDS are an example of existing short implants.

Microimplants, for their part, are very thin implants between 1.3MM to 2MM wide and approximately 10MM long whose use is exclusive in orthodontic treatments since they only support traction forces of up to 300g. The Unitek ™ implant from 3M is an example of an existing microimplant.

There are to this day multiple inventions that seek to combine a central dental implant with one or more thinner implants that cross it, inventions that seek to provide more stability to the first implant, although none of them provide a concrete, simple, practical and viable solution. application and clinical manipulation of the device, many of which are impossible to perform and impossible to put in the mouth or simply unrealistic. In addition, many of them do not provide a universal prosthodontic solution since they involve an abutment for cementation or prosthetic anchoring in their design. Some of these patents are listed below:

EXPLANATION OF THE INVENTION

In order to correct the defects described above, the invention proposes an invention that is simple to make and use, realistic, very versatile, ergonomic, respecting the established technical standards and very original. This invention is a variant of the precision biphasic guide and its method to fix a tripod with a short dental implant function in a low jaw bone using a surgical guide, which is made up of two elements, a buccal splint with concentric caps attached. by a set of rings of increasing internal diameter associated with a micro-drill guide and the body of the tripod with its legs. These elements must be designed with a geometry and precise measurements for the proper functioning of the device. This biphasic guide allows to fix a tripod consisting of a central body and three legs and, as its name indicates, the guide consists of two phases of use.

In the first phase of using the biphasic guide or fixing phase of the tripod body, we use the buccal splint and the tripod body. This splint allows in a first step to drill in the bone to later fix the body of the tripod. This body is a solid, cylindrical, glass-shaped object with a wide ground. This vessel contains a polyhedral cavity open upward, surrounded by a cylindrical wall and superimposed on the floor of the one that is cylindrical. Outside this wall is smooth and this floor is rough and has external helical threads. Inside this floor is perforated by a minimum of four perforations that start from the bottom of the cavity of the glass, a bottom that is also the upper base of the floor of the glass. Three of these perforations are inclined and cylindrical, identical to each other, and their central axes intersect with the central axis of the vessel at the same point above the object. These perforations do not touch each other. The centers of the entrances These perforations, located at the bottom of the polyhedral cavity of the vessel, draw an equilateral triangle. The outlets of these perforations are located on the sides or at the lower base of the floor of the vessel and their centers also draw an equilateral triangle, but larger than the one mentioned above. These three perforations surround without touching it a fourth cylindrical perforation, located in the center of the floor of the vessel, a perforation that does not cross the floor and is surrounded by a wall with internal helix threads. This serves to fix on the tripod body, by means of a simple head screw, the appropriate dental prosthesis when appropriate. The cavity of the vessel has the particularity of containing a polymorphous structure in the form of a cavity or alternatively of a projecting mound. The oral splint contains a series of overlapping caps that surround each other, with the largest diameter being the outermost. These bushings are attached by means of a ring, perfectly threaded to the uppermost part of the outermost or larger diameter bush, which allows them to be locked together and with the splint itself.

Thus, once the tripod body is located, in a second phase of use or phase of fixing the tripod legs, we remove the first ring, we remove the most central cap that has served to guide the placement of the tripod body, we introduce in the next bushing the micro-drill guide and we block the set with a new ring with a larger internal diameter.

The microdrill guide is a solid block with the shape of a cup without a shaft whose foot is polyhedral and whose calyx is cylindrical, alternatively containing an upwardly open and polyhedral cavity or a solid and cylindrical block. The foot of the guide has four holes. Three of these holes are inclined, they are cylindrical, identical to each other and their central axes intersect with the central axis of the guide at the same point above the object. These holes do not touch each other and go completely through the foot. The centers of the entrances of these holes, located at the upper base of the guide foot, draw an equilateral triangle and, the centers of the exits of these holes, located at the bottom base of the guide foot, draw an equilateral triangle of larger than previously described. These three holes surround without touching a fourth polyhedral hole, drilled from the center of the upper base of the guide foot downwards without going completely through it. This foot further contains a cavity-like or alternatively projecting mound-like polymorphous structure that are the exact antagonists of the aforementioned polymorphic structures of the tripod body, thus allowing a single oriented entry of the drill guide into the tripod body. Above and around this foot is the chalice of the guide which is alternatively a cylindrical ring that is fixed and surrounds the foot above and outside, and that contains a polyhedral cavity open upwards and delimited at the bottom by the upper base of the guide foot or a cylindrical block.

This guide is inserted into the cap of the surgical guide, repositioned in the patient's mouth and having removed the ring containing the caps, and is attached above the body of the tripod serving as a stopper and being fixed by the aforementioned ring and thus remaining perfectly interlaced to the body of the tripod and attached to it. In this phase we drill the bone through the body of the tripod to later position its legs, which are osteosynthesis screws. With the legs already placed on the bone, we can place a dental prosthesis on the tripod obtained when appropriate, thus serving this short dental implant tripod.

PREFERRED EMBODIMENT OF THE INVENTION

As already indicated, the variant of the precision biphasic guide and its method to fix a tripod with a short dental implant function in a low jaw bone using a surgical guide, is composed of two elements, a buccal splint with caps. concentric links joined by a set of rings of increasing internal diameter associated with a micro-drill guide and the body of the tripod with its legs. In the first phase of using the biphasic guide or fixing phase of the tripod body, we use the buccal splint and the tripod body. This splint allows, in a first step, to drill into the bone through its innermost sleeve, to later fix the tripod body. This body is a solid, cylindrical, glass-shaped object with a wide ground. This vessel contains a polyhedral cavity open upward, surrounded by a cylindrical wall and superimposed on the floor of the one that is cylindrical. Outside this wall is smooth and this floor is rough and has external helical threads. Inside this floor is perforated by a minimum of four perforations that start from the bottom of the cavity of the glass, a bottom that is also the upper base of the floor of the glass. Three of these perforations are inclined and cylindrical, identical to each other, and their central axes intersect with the central axis of the vessel at the same point above the object. These perforations do not touch each other. The centers of the entrances of these perforations, located at the bottom of the polyhedral cavity of the vessel, draw an equilateral triangle. The outlets of these perforations are located on the sides or at the lower base of the floor of the vessel and their centers also draw an equilateral triangle, but larger than the one mentioned above. These three perforations surround without touching a fourth cylindrical perforation, located in the center of the vessel floor, a hole that does not go through the floor and is surrounded by a wall with internal helix threads. This serves to fix on the tripod body, by means of a simple head screw, the appropriate dental prosthesis when appropriate. The cavity of the vessel has the particularity of containing a polymorphous structure in the form of a cavity or alternatively of a projecting mound. The oral splint that contains a series of cylindrical, hollow and imbricated caps that surround each other, the outermost being the one with the largest diameter attached to the splint. These bushings are first joined by means of a ring, perfectly threaded to the uppermost part of the outermost or larger diameter bush, which allows them to be locked together and with the splint.

In a second phase of use or phase of fixation of the tripod legs, we remove the first ring, remove the most central sleeve, insert the micro-drill guide in the next sleeve and lock the assembly with a new ring with a larger internal diameter.

The microdrill guide is a solid, cup-shaped block without a shaft whose base is polyhedral and whose calyx is cylindrical, alternatively containing an upwardly open, polyhedral cavity or a solid, cylindrical block. The foot of the guide has three inclined, cylindrical holes, identical to each other and their central axes intersect with the central axis of the guide at the same point above the object. These holes do not touch each other and go completely through the foot. The centers of the entrances of these holes, located in the upper base of the foot of the guide, draw an equilateral triangle and, the centers of the exits of these holes, located in the upper base of the guide draw a larger equilateral triangle than the one described above. This foot further contains a cavity-like or alternatively projecting mound-like polymorphous structure that are the exact antagonists of the aforementioned polymorphic structures of the tripod body, thus allowing a single oriented entry of the drill guide into the tripod body. Above and around this foot is the calyx of the guide, which is alternately a cylindrical ring that is fixed and surrounds the foot above and outside, and that contains a polyhedral cavity open upward and delimited below by the upper base of the guide foot or cylindrical block.

This guide is inserted into the next sleeve of the surgical guide, repositioned in the patient's mouth and having removed the retaining ring from the caps, and is attached above the tripod body serving as a stopper and being fixed by means of the aforementioned ring. and thus remaining perfectly interlaced to the body of the tripod and attached to it. In this phase we drill the bone through the body of the tripod to later position its legs, which are osteosynthesis screws.

With the legs already placed on the bone, we can place a dental prosthesis on the tripod obtained when appropriate, thus serving this short dental implant tripod.
