Description

DESCRIPTION REPORT OF THE INVENTION "STRUCTURE GUIDELINES GUIDE FOR OBTAINING FIXED PROSTHESIS PROVIDED FROM FITTING OPENING, ADJUSTMENT AND FIXING OF PREVIOUS MANDULAR IMPLANT IMPLANTS

APPLICATION FIELD

The present title patent and object of description and claim of this title is an inventive solution of relevant utility in the human medicine sector, notably in the field of dentistry and specifically in the field of implantology, finding particular benefit in the manufacture of Dental or partial dentures supported by dental implants, also known as fixed dental prostheses.

DEMAND FOR INVENTION -

From the patient's point of view: the inventor identifies the imperative need to ensure the making of a dental prosthesis, notably an implant-supported dental prosthesis, with differentiated quality, not only in terms of the final finish, but especially to ensure its perfect positioning and fixation. close to the remaining alveolar ridge, such that once applied to the patient's jaw or jaw, it provides the patient with outstanding comfort and convenience, especially during the chewing exercise, immediately after implant placement.

From the perspective of the implantodontist: the inventor identifies the imperative need to ensure the manufacture of a prosthesis, notably a total or partial fixed prosthesis supported by implants, such that when the procedure of "application" of that prosthesis in the patient it is performed in an agile manner, provided with ergonomics of application for the dentist, ensuring a perfect adherence of the prosthesis to the implants previously fixed in the individual's jaw or jaw so that it eliminates, or to the least minimize the need for adjustments of this prosthesis to the implant set.

As a result, a drastic reduction in the time required for the procedure of adjusting and fixing the dental prosthesis in the maxillo-mandibular bone structure is required, around 20% of the conventional time, thus converging to a favorable ergonomic condition for both. the implant dentist as for the patient, especially due to the fact that the reduction of the procedure time reduces the mental and physical stress of both mentioned actors.

From the perspective of the fixed prosthesis: the inventor identifies the imperative need to ensure the making of a prosthesis, notably an implant-supported dental or partial prosthesis, which once fixed to the individual's jaw or jaw, is effectively "functional" without For this, its structure operates in a tensioned way, minimizing the possibility of fatigue of its structure and thus extending its useful life on the bone rim that received it.

INVENTION REQUIREMENTS

In line with the demand of the inventor, the applicant devised an unprecedented "guiding guide structure for obtaining a fixed implant supported prosthesis provided with openings with a snap function, adjustment and emergency fixation of dental implants previously applied to the maxillary bone structure. mandibular structure ", being that this structure is a complete physical model that, besides reliably reproducing the organic form of the gingival relief, the mandible maxillary relation (vertical dimension) and the occlusion (dental arrangement), already available in conventional technique, unpublishedly adds a plurality of projections whose position and spatial inclination accurately reproduce the position and spatial inclination of the respective plurality of prosthetic emergencies, such as cylinders, of the corresponding fixation implants supporting the fixation of the dental prosthesis itself so that when this model is used for the prosthesis itself, by the professional (dental technician), for example, will entail obtaining the body of the prosthesis, which reproduces a surface perfectly adjustable to the gingival relief, also provided with corresponding "passage openings" properly aligned with the aforementioned prosthetic emergencies (cylinders) of dental implants previously fixed to the maxillary or mandibular bone structure. The implants, when making the prosthesis in the laboratory, are not yet installed. Implant projections in the guide are made from the virtual surgical planning. Surgery, that is, the actual definition of implant positioning is performed after the prosthesis is made. The prototyped guide guides the prosthetic to make a structure (prosthesis) based on planning, ie future position of implants.

As evidenced in the previous paragraph, the "plurality of reliable protrusions" by ensuring a perfect coupling of the "dental (or partial) + dental implants" set thus confer the novelty requirement associated with the activity. inventive, as it does not follow from obvious or obvious other solutions known in the art when making such prostheses. Ultimately, the invention "in the form of a structure first generated in 3D technology, ie digital and later consolidated in the making of a physical model is provided with industrial applicability, being economically viable and therefore meeting the stringent patentability requirements. , notably as a patent for invention, as provided for in Articles 8 and 130 of Law 9.279.

TECHNICAL BACKGROUNDS

In order to provide truthfulness; and to consolidate the context explained in the topics of the introductory table, a brief explanation about the medical area pertinent to oral health and conservation will be presented, especially regarding implant dentistry, including the understanding of procedures and products known in implant dentistry treatments, showing within this context the current state of the art for the use, fabrication and implantation of "implant supported dental or partial prostheses", where after critical analysis of these, once exposed to professionals with expertise in the field of implant dentistry, these will be able to identify its limiting aspects, thus consolidating the identification of the needs of demands for the unprecedented "orientation guide structure for the formation of openings in implantable fixed prosthesis" fixed in the maxilla and / or mandible arch of an individual undergoing nature treatment. of implant dentistry.

The. Tooth health: Individual teeth loss occurs due to factors known as dental caries, gum disease, trauma, poor hygiene, among others, where the absence of a tooth and the consequent presence of the gap left by it impacts the dynamics of teeth. the other teeth, as they move in these free spaces, converging in functional imbalance of the entire dental arch.

In addition to the absence of one or more teeth, in the absence region there is a phenomenon of alveolar bone resorption (disappearance due to absorption by the organism), which is the alveolar bone where the roots of the teeth are implanted.

B. From the restoration of the dental arch:

In order to treat the dental arch

Through restoration of masticatory, aesthetic and phonetic functions, and to minimize the negative effects generated by the absence of tooth (s), there is an area within dentistry, called implant dentistry, which among other competences stands out for its development of dental implantation techniques, which in turn implies the development of a large portfolio of dental prostheses.

ç. State of the art:

cl Dental prostheses: may be removable or fixed, the latter finding representatives such as crowns and total (or partial) fixed prostheses supported by implants, and for the purpose of understanding the present demand of this patent the invention elects the latter as development paradigm.

In turn, implant supported dental prostheses are formed by the dental prosthesis + fixation implants set.

Basically the piece "dental prosthesis" can be composed of a main body component, made of acrylic resin, for example + dental arrangement (sets of artificial teeth). c.2 Manufacturing process of implant supported dental prostheses:

c.2.1 Obtaining the dental arch model of the individual: In earlier times and still quite often in modern times, the "physical model" of the dental arch, jaw and or jaw, is obtained conventionally, where the dentist takes a impression (or manual molding) of the dental arch of the individual, both the jaw and the jaw, by means of a moldable mass, which once applied to the buccal cavity, is expected a certain time of hardening of this mass, so that it is obtained the structural stability of this "impression" or molding, thus defining the "primary mold", where in possession of such a mold the prosthetic professional pours plaster within the said molding, in order to obtain a "jaw model" (in the example - model without this). teeth) and or the jaw ", to which the professional starts to assemble and fix the plurality of dental prostheses.

Obtained the "physical models" of the two arches of the patient, which will receive the prosthesis and the opposite, called antagonist to the other, they are properly mounted next to a prosthetic device, technically called "articulator"

However, once the physical model is assembled in the articulating device, it will have the following information:

- Gingival relief;

- the distance between the arches and

consequent height of the teeth; and

- The teeth arrangement. c.2.2 Planning and execution of dental implants: the professional with reliable information about the occlusion and gingival relief of the alveolar ridge and / or jaw defines, with the aid of the articulating device, the best cartesian position and spatial inclination of the teeth. dental implants that will ultimately promote fixation of the fixed prosthesis (s), and with this information the professional proceeds to the application of these fixation implants by drilling the gingival relief and bone layer of the alveolar edge of the jaw and / or jaw with subsequent application of screws (dental implants which in most cases are cylindrical or tapered) which at the end of fixation define a plurality of prosthetic emergencies, such that the jaw and / or jaw are ready for use. receive the "dental prosthesis" itself. In addition to the implant, a prosthetic part (prosthetic abutment) is placed between the implant and the prosthesis, which is important because it allows to change the angle of the axis defined by the implant.

c.2.4 Preparation of the prosthesis for fixation: Once the dental prosthesis has been obtained, using the maxillary mandibular models provided each of the dental arrangement, the dentist should promote a plurality of passing holes on the prosthesis body. where the Cartesian coordinates of these holes must coincide with the Cartesian spatial position of the plurality of fixation implants previously installed in the buccal cavity (maxillary and or mandible).

c.2.5 Fixation of the dental prosthesis in the oral cavity: the dental professional promotes the positioning of the dental prosthesis close to the oral cavity seeking the alignment of the passing holes with the prosthetic emergencies (cylinders), where once properly assembled the described set is consolidated. the fixation with these prosthetic emergencies, by applying adhesion resin. Alternatively, and in contemporary times, professionals in implant dentistry to make models of the mandible and jaw, use a technique such that from the data collection by means of computed tomography of the individual's dental arch these data are digitized, using specific software for this purpose, such that a three-dimensional "digitized virtual virtual model" of the individual "dental arch" is generated for each individual.

In turn, the "three-dimensional digitized virtual model" is taken for reading in a rapid prototyping 3D printing equipment, so that in the end the prototype of the physical model is obtained, notably from the body of this total prosthesis, either for the man. - dibula and or to the jaw.

This technique of obtaining digitized dental prostheses is revealed in patent documents, and among many, the inventor believes it is pertinent to cite:

- US 5725376, deals with the making of a dental implant through the creation of a computerized model that provides structural details of the jaw, information about the gingival relief and the teeth proposed for this specific prosthesis and that consequently enables the preparation by dental technique. rapid prototyping of the prosthesis itself.

This invention is distinctive, as having a computerized model, the practitioner has at hand three-dimensional information of the bone structure of the gum surface and the previously documented and referenced images of the teeth, thus allowing Cartesian positions to be defined for the precise execution of the procedure. fixation of the dental implant fixation.

- US 20110177476, deals with obtaining a prosthesis to be fixed on the maxilla and or maxilla of the dental arch of an individual, which is fixed by means of fixation implants previously defined in that dental arch, where this prosthesis includes a structure which is configured to be screwed onto these implants.

Problem ID:

The detailed study of the known solutions evidenced in the state of the art for implant supported dental prostheses reveals that, although they are made with great fidelity, when led to the expert appraisal of the dental implantation procedure, they unanimously understand that there is a significant and relevant degree of difficulty in this procedure, notably by the fact that once the aforementioned total prosthesis is made, it is mandatory to make through openings in the posterior part of the prosthesis itself.

In addition, it is a concrete fact that for the accomplishment of the abovementioned openings, the dentist performs it with a high degree of inaccuracy, due to the fact that individualized markings are necessary, even for approximation to the Cartesian coordinate. of the plurality of emergencies of dental implants already installed in the bone structure of the maxilla and or mandible.

As a result of the inaccuracy in the marking and execution of the passing openings in the total prosthesis, lies the fact that the lack of alignment of the "passage openings + emergencies (cylinders) of the plurality of fixation implants" converges in a fixation with unwanted tensioning of the total prostheses, passing through a fixation of this prosthesis that generates discomfort in the individual's dental arch and ultimately may make the aforementioned fixation impractical, which converges on the rendering of the previously made dental prosthesis.

Still due to the complexity of the operation of mounting + adjustment + fixation of the dental prosthesis with the emergence of the fixation implants, the long time required to do so results, which in turn leads to a high degree of compromise in physical comfort. both the dentist and the patient himself.

Cause of the problems: the inventor understands that the problems listed are due to the absence of devices that guarantee a perfect Cartesian (x, y) positioning of the dental openings through the corresponding Cartesian coordinates of the prosthetic emergencies of the plurality of implants. fixations previously applied to the patient's jaw and or jaw.

PROPOSAL OF THE INVENTION

The inventor, aware of the gap that exists for the perfect application of the dental prosthesis to the prosthetic emergencies of the plurality of implants previously fixed to the jaw and or jaws; and consequent deficiency of the application of this prosthesis, proceeded to the development of an unprecedented technique of confection of the improved dental prosthesis, whose distinguishing feature is the relevant fact that, once made, it is already provided with plurality of openness. bypass grafts with the same Cartesian coordinate (x, y, z) as those mentioned by the pluralities of the fixation implants already fixed to the maxilla and / or mandible.

The. Technical feasibility: For such a technical condition of open-ended dental prosthesis to be feasible, the inventor, using 3D modeling technology to perform prosthetic surgical planning, and devised a "mathematical model" (technical term used in activity). product design using CAD tool) that adds the following information:

1. 3D model of the bone structure, the

xila and / or the jaw;

2. 3D model of gingival relief superimposed on the surface of the maxillary and / or mandible alveolar bone;

3. 3D model of the dental arch, ie, dental arrangement applied to the model of bone structure and gingival relief of the jaw and / or jaw;

4. Ratio of teeth height; and

5. 3D model of the plurality of angular inclined cylindrical projections and Cartesian coordinates x, y and z, corresponding to the emergence coordinates of the fixation implants previously applied to the mandibular maxillary bone structure. In fact, they are implanted immediately before the prosthesis installation and their positions, as well as the prosthesis, are also defined in the virtual planning.

B. Distinctive feature:

bl Guide structure: for making the denture with through openings for adjustment and fixation of emergencies of the plurality of fixation implants, translated by the set of 3D models of the bone cavity, gingival relief, occlusions and distance between teeth and cylindrical projections. the latter is effectively the object of differentiation from the prior art, and such a set of 3D models is the reference for the prototype generation in the form of a physical model, which prototype generated using rapid prototyping technology, such as selective laser sintering on various printing platforms. b.2 Procedure for making the complete prosthesis: Preliminarily the professional assembles the following set of physical parts next to the articulator:

- first physical model of the jaw (for example) obtained by conventional physical modeling procedure;

- Second physical model, this one of the guide structure, which is complementary to the first physical model, obtained exclusively by 3D modeling procedure with subsequent printing with rapid prototyping technology, because only this way it is possible to define the cylindrical projections in the Cartesian inclinations and coordinates x, y and ζ corresponding to the respective Cartesian inclinations and coordinates x, y and ζ of the emergencies of previously planned implants performed in the bone structure of the maxilla as in the present example;

The assembly procedure of the physical models mentioned in the articulator apparatus allows the prosthetic professional to obtain the correct spatial position information between the maxilla and mandible on the x.y and z axis.

Having the first and second physical models of the mandible and jaw with the guide structure, properly adjusted in height in accordance with the previously defined vertical distance, the prosthetic professional proceeds to section the plurality of cylindrical projections, thus eliminating the segment formed by the occlusal third of the teeth [occlusal face] of the maxilla (in line with the present example), such that it results in the second physical model formed by a superficial area (equivalent to the gingival relief of the maxilla). ) and plurality of discrete projections (remaining from the section procedure of this physical model). According to the technical condition obtained up to the present point of the description, the necessary condition is created for the prosthetic professional to perform manual resin modeling procedures in the intermediate space formed between the lower part of the first model (maxilla) with plurality of discrete projections with the second physical model (in this case the jaw).

At the end of the described procedure, the dental prosthesis of the maxillary arch is obtained, referring to the present invention, where this prosthesis is differentiated by presenting a plurality of openings formed by the action of the plurality of discrete projections defined in the physical model of the maxilla. (in the example).

b.3 Application of the open dental prosthesis: the dental professional must have the following technical condition:

- Have the dental prosthesis provided with a plurality of openings;

- Have the patient, in the case of the present example, his jaw already prepared with the plurality of fixation implants properly installed in the alveolar bone;

Having in mind the technical condition described above, it is sufficient for the dentist to proceed, after standard preparation of the patient, the fixation of the prosthesis fixed on the jaw in such a way that it seeks the alignment of the plurality of openings of this dental prosthesis with the respective plurality. emergencies of implants previously applied to the patient's maxilla bone structure.

The inventor draws attention to the relevant fact that with the inventive technique now idealized the procedure of mounting the dental prosthesis next to the emergencies of the implants is immediate, without the need for adjustments because when the opening of the dental prosthesis the diameter of these already It is performed "the largest" precisely to allow the slight absorption of variations in the final implant positioning that the previous surgical technique can provide.

Finally, to consolidate the fixation of the fixed prosthesis on the alveolar ridge of the jaw, the professional applies resin in the space between the diameter of each prosthesis opening and the emergence (prosthetic abutment) of the respective fixation implant.

DETAILED DESCRIPTION

The following detailed description is to be read and interpreted with reference to the presented drawings which are not intended to limit the inventive scope, which is limited in the appended claims.

The. From the state of the art:

The inventor understands that, to provide a better understanding of the demand of the present invention, it is pertinent to present the conventional constructive concept of a dental prosthesis supported by fixation implants, further highlighting the problems identified as lack of precision, reliability, quality, durability and operational dynamics, resulting from the need to make through openings in the body of the prosthesis itself as soon as it is made.

As shown in the previous paragraph in Figure .1, a representation of a model (A) is shown, notably a jaw overlapped by a gingival relief (Ge) which is in turn overlapped by a dental prosthesis (Pr), which in turn is formed by a resin body (Ca) to which is axially anchored a plurality of artificial teeth (De) for example, where the constructive concept resin body (Ca) + set of teeth (De ) is shown by Figures 2a and 2b respectively.

In order to make the fixation of the total prosthesis (Pr) close to the gingival relief (Ge) feasible, it is mandatory to make a plurality of through openings (Ib) on the surface (Ia) of the resin body (Ca), where to do so. The dental professional makes use of drill-type equipment, and it is usual to use a tapered cutter or grinder (Es), as shown in figure .3a and figure .3b respectively.

The relevant fact in this procedure, which is considered restrictive, is the need for the dentist to make the individual openings (lb), that is, one by one, where the markings for the drilling imply the mandatory condition to proceed with repetitive movements of placement of the prosthesis in the patient's mouth, adjust this prosthesis with the emergencies (In) of the implants, where such adjustment procedure becomes more complex as there are openings (Ib) previously performed with the execution of a new opening (Ib) for another emergency (In) implant to be performed.

Ultimately once prepared, the resin body (Ca) already with its surface (1a) provided with the plurality of through openings (Ib) the dental prosthesis (Pr) is definitely positioned over the gingival relief (Ge), such that such openings (Ib) are aligned with the prosthetic emergencies of the fixation implants (In) previously fixed to the bone structure of the jaw (elected for the present description) as shown in Figure .4. This can only be made after the placement of the implants and not before as in the case of this (our) patent, that is, the implants are placed, the impression is made, the model and then the prosthesis confection is started.

b · Process for obtaining the guide structure: As illustrated by Figure .5, the inventor makes mandatory use of CAD / CAM technology, ie, English-language acronyms representing "Computer Aided Design" and "Computer Aided Manufacturing" ", where the operator (Op) of this system handles information in the following steps:

Step (1): As evidenced in figure .5 by patient-specific dental arch hardware / software (Pc), obtained by 3-dimensional facial computed tomography, which generates specific digital data including reference information. gingival reveal (Ge), bucomaxillary positioning and positioning (virtual planning) of dental implants, both in the patient's maxilla and mandible;

Stage (2): in possession of the 3D models of the bone structure (Os) and gingival relief (Ge) of the patient's jaw or jaw, where as an example in the description of this cartouche, dental prosthesis is elected ( Pr) for the patient's jaw, where still making use of CAD software, this same operator (Op) initiates the modeling of the guide structure (1), having as a paradigm the preliminary implantation planning, such that digitally models a plurality of columns (Pi) that have exactly the Cartesian inclination and coordinate x, y and ζ of each of these pillars (Pi), then generating their mathematical model, and in addition the 3D modeling is performed. to the new jaw dentition (according to the example of the present detailed description), where the practical result of such a multiple modeling procedure is appreciated through figures 6a; 6b and 6c respectively, where the guide structure (1) is formed of the following elements:

- bone structure image (Os);

- gingival relief image (Ge); - dental arrangement image (De), notably the occlusal third of the teeth; and

- image of the plurality of pillars

(Pi)

Step (3): Still making use of a 3D modeling CAD software, the middle and cervical third of the teeth (notably the lower teeth) are deleted from the 3D model of this second model, as evidenced by Figures 6a; 6b and 6c respectively; and

Step (4) Holding the 3D digital model, showing the bone structure (Os) plus plurality of guide pillars (Pi) emerging from the gingival relief (Ge) + gingival relief (Ge) + occlusal third of teeth (De), the operator (Op) uses CAM software and generates a physical model, which is referred to in this cartouche as the first physical model (ml), using rapid prototyping printing technology. physical model is identical to the 3D virtual model viewed in CAD software; as shown in the lower part of figure .7;

c · Process of obtaining the total prosthesis: for this procedure, the prosthetic professional must have the following physical resources:

- articulating apparatus;

- first physical model (ml): obtained by rapid prototyping, and differentiated by presenting a plurality of guide pillars (Pi) and occlusal third of the teeth (De)

- second physical model of the mandible (m2): conventionally made in plaster, and representative of the antagonist dental arch to the patient's jaw (according to the example where the denture in the jaw is elected),

With these resources, the prosthetic professional proceeds to the sequential steps:

Step (1): Assembly of the first physical model (ml) and the second physical model (m2) on the articulator apparatus, with conventional adjustments / adjustments as shown in figure .7;

Step (2) Adjustment / Adjustment of the model according to physical model (m1), mounted on the articulating device (not shown), very common and necessary in the area of implant dentistry, together with a first model (m2), which in turn is made so conventional, in plaster, and representative of the antagonist dental arch of the patient's jaw (according to the example in which the making of the denture in the maxilla is elected), as evidenced by figure .7. This condition is necessary to establish the interocclusal relationship and the vertical occlusion size of the patient. It is at this point of the cartouche the relevant comment that the models are of dental prostheses but the inventive technique can be applied in partial dentures.

Step (3): The prosthetic professional proceeds to section the plurality of guide abutments (Pi) thereby eliminating the segment formed by the occlusal third of the teeth (occlusal face of the teeth) of the jaw (in line with the present example), in such a way which results in the first physical model (ml) formed by a surface area (equivalent to the gingival relief of the jaw) and a plurality of discrete projections (Pi ') remaining from that section procedure of that physical model (ml), as evidenced by the figure. 8;

Step (4): confection of the dental prosthesis (Pr), where still in the articulating apparatus, as evidenced by figure .9, the prosthetic professional performs manual resin modeling procedures in the intermediate space formed between the upper part of the second model ( m2) and the lower part with plurality of discrete projections formed in the first physical model (ml), and at the end of the described procedure the dental prosthesis (Pr) of the maxillary dental arch (elected as an example for the description of the present invention) is obtained, as shown in figure .10.

Step (5): Removal of the dental prosthesis (Pr) from the articulating appliance, as evidenced by Figure .11, where this dental prosthesis (Pr) presents the resin body (Cal) and tooth arrangement (De), as as a conventional dental prosthesis, being differentiated by presenting a plurality of openings (Ca2) formed by the action of the plurality of discrete projections (Pi ') defined in the first physical model (ml).

These openings (Ca2) have a nominal diameter greater than the emergence diameter (In) of the defined fixation implants and applied to the bone structure (Os) of the patient's maxilla (Ma), a difference that is necessary to provide the prosthesis adjustment margin. (Pr) when fixed on the gingival relief (Ge) of the maxilla (Ma).

d. Dental application process: For this procedure, the dental professional must have the following physical resources:

Dental prosthesis (Pr) differentiated with the plurality of openings (Ca2), as evidenced by Figure 11; - maxilla (Ma) provided with a plurality of fixation implants (In) and their emergencies, with the cartesian angles and coordinates x, y and ζ corresponding to how preliminarily planned having as a paradigm tomographic record information on the patient's face; as evidenced by FIG. 12;

With these resources, the dentist proceeds to the sequential steps:

Step (01): Placement and assembly of the dental prosthesis (Pr), with its overlap to the gingival relief (Ge) of the maxilla (Ma), for example, such that the emergencies of the implants (In) pass through the respective openings. (Ca2) defined on the surface (Cal) of the resin body of this dental prosthesis (Pr); as evidenced by figure .13. In this procedure the larger diameter of the openings (Ca2) in relation to the diameter of the emergencies of the implants (In) is beneficial because it allows discrete adjustments for the perfect positioning of the dental prosthesis (Pr) over the gingival relief (Ge); and

Step (02): fixation of the dental prosthesis (Pr) to the gingival relief (Ge) where the dentist uses a bottle (Fr) of resin (Re), notably an acrylic resin, so that it is applied. in the void between the opening (Ca2) and the implant emergence diameter (In), which is a metal cylinder screwed to the implant as shown in Figure 14.

As a practical result, for the dental professional, the guide piece (1) makes it possible to obtain a dental prosthesis (Pr) with pre-defined openings (Ca2), which provides easy and precise coupling to the emergence of the fixation implants (In ), having as reference in the correct positioning (x, y, ez) because it counts on the registration of the gingival relief, conferring a prosthesis, notably a fixed denture with the best bite adjustment possible, thus reducing the operative time and consequently sharp reduction. the discomfort of both the implant surgeon and the patient.

The choice of the preferred embodiment of the invention in the form of a constructive concept of the differentiated dental prosthesis (Pr) with a plurality of previously defined openings (Ca2) in the resin body, as well as its fabrication process and ultimately its assembly procedure and Attachment to the gingival relief of a patient's mandible and or jaw, which is the object of claim in this cartouche, described in this detail topic of the invention is provided by way of example only. Changes, modifications, and variations (such as the inclusion of a metal framework for dental reinforcement) can be performed for any other embodiment of both the dental prosthesis (Pr) of its fabrication process and assembly and application procedure. to the patient by those skilled in the art without, however, departing from the objective disclosed in the application of the present patent, which is exclusively defined by the appended claims.
