Definitions
- the present invention deals, as its name indicates, both with a procedure for manufacturing dental prostheses, as well as with dental prostheses themselves, both constituting a clear advance both in the quality and in the speed of the final product.
- the invention is aimed at the manufacture of dental prostheses, such as dentures, where traditional artisan or purely manual techniques are combined or merged with other more recent ones based on digital design, thus obtaining a result that has the advantages of both. techniques.
- the present invention deals with both new digitally designed dental prostheses and the procedure, also digital, for their manufacture.
- Said prostheses therefore come to replace those commonly known as “removable” or “fixed” acrylic teeth, which are manufactured with manual or artisanal procedures. Thanks to it, therefore, a better design is achieved as well as greater precision, which helps to minimize the errors produced by human intervention in the referred artisanal procedures.
- acrylic teeth belong to families or collections of teeth with standardized geometries that are chosen by the patient or their specialist. according to your preferences (shape and color), oral morphology, resemblance to your own teeth, etc.
- this model with the acrylic "splint" teeth already assembled and adjusted on it is placed in a flask or mold to be able to pour liquid resin under pressure that occupies the space of the wax (which acts as the patient's gum). that holds the necks of the teeth and then proceed to cure the dental prosthesis obtained by adding heat (either to the water bath, microwave, etc.), ending with a final treatment of the prosthesis that gives it the final appearance .
- these types of artificial teeth are manufactured by combining several different acrylic resins that reproduce the natural layers of enamel and dentin, all of them created based on the polymerization of acrylic monomers, crosslinking and reinforcing agents, acrylic resins, pigments and other non-toxic additives forming a unique composition to achieve the best performance and thus achieve with the union of the layers a compact set of appearance and behavior similar to natural teeth, both for its color and its stability, as well as its mechanical characteristics (hardness, resistance to abrasion and external agents, etc.).
- these layers of acrylic resin are manufactured on the basis of producing a highly cross-linked and reinforced high molecular weight acrylic polymer whose robust weave of high molecular weight cross-linked chains provides teeth with great resistance to abrasion and unalterable coloration. , which also has a light effect similar to natural teeth.
- this polymerization is carried out by means of a process of selective injection-compression molding of the layers, known by its acronym in English SICM (Selective Injection-compression molding), which inhibits the formation of porosities, prevents polymerization contractions and over everything achieves the chemical adhesion of the layers, by curing and hardening all at the same time, which gives the tooth greater physical and chemical resistance.
- SICM Selective Injection-compression molding
- this method consists in that, on a digital image of the patient's mouth, obtained either by direct scanning of the same or by scanning a model obtained by any conventional technique, both the dental pieces such as the gum that make up the prosthesis.
- the gingiva In the case of the gingiva, this can be manufactured using 3D printing or milling, that is, by machining a piece with increased geometry compared to the final one.
- milling when milling is used, it has the double disadvantage of, on the one hand, that it is a long and expensive process due to the amount of material that is wasted and, on the other, that it is very difficult to obtain results aesthetically similar to reality due to the complex geometry of the gums.
- teeth can also be made by 3D printing or milling.
- this process is long and expensive on the one hand due to the abandonment of material and, on the other, it is also difficult to obtain aesthetically similar results to reality due to the geometry of teeth.
- the aesthetic appearance of said dental pieces is far from appearing natural given the degree of finish that these types of techniques allow, mainly because they are made of a single-color base material. For this reason, the pieces thus manufactured are usually used only as temporary prostheses intended to be in the mouth for a very short time.
- the gingiva and teeth are assembled by gluing with resin or another known component and, finally, the usual final treatment of the prosthesis is carried out, which gives it the final appearance.
- the procedure for manufacturing dental prostheses and dental prostheses included in the present application solve the aforementioned drawbacks in the processes known in the state of the art, resulting in prostheses or dentures that reproduce with total precision and accuracy both the design made by computer that adapts to the patient's mouth, such as the dental aesthetics required in a definitive prosthesis, all this quickly and economically and without impairment of the quality required of this type of definitive prosthesis as they are made more precisely, minimizing errors.
- the invention that is now described consists, on the one hand, in the combination or fusion of the processes already known in the state of the art.
- the traditional or artisanal process shown in Figure 1 uses the method of manufacturing acrylic dental pieces by means of the mentioned process of selective injection-compression molding of the layers (SCIM) that today achieves very good results both aesthetic as well as functional, but with the novelty that said dental pieces are part of digital libraries so that they can be digitally manipulated during the prosthesis manufacturing process.
- SCIM selective injection-compression molding of the layers
- the method of the invention uses modern 3D printing processes for the manufacture of the gingiva, as is already being done in the processes of the state of the art described above and which can be seen in Figure 3.
- the procedure of the present invention is based on, from the digital information of a patient's mouth, an existing digital library of dental pieces and a software tool, to design the most suitable dental prosthesis for each patient in a fully digital way.
- the gingiva is manufactured using a 3D printing technique and the dental pieces in acrylic material using a selective layer injection-compression molding (SCIM) process.
- SCIM selective layer injection-compression molding
- the invention is characterized in that the subsequent union or assembly of the teeth on the gums is carried out by means of tongue and groove between both.
- the aforementioned teeth and the gingiva are designed so that the teeth comprise a hole or female part in their lower base that joins the gum and, for its part, the gum comprises an extension or protruding male part.
- both parts will fit precisely thanks to the design of said tongue and groove is also part of the digital design of both, so that once manufactured their coupling will be optimal.
- both the female part located in the tooth and the male part located in the gum are designed according to the type of tooth, that is, if the tooth is an incisor, the total dimensions of said tongue and groove will not be the same as if it is an incisor, a molar, etc., since its digital design takes into account the masticatory loads that each one supports, as well as the amount of material available in the tooth so that it does not affect its aesthetics . In this way, an optimal union is achieved in terms of resistance, functionality and aesthetics.
- Said tongue and groove joint will also be reinforced with the use of a suitable cement, glue or acrylic resin to ensure a durable and reliable joint between the teeth and the gum, greatly improving the performance of the processes currently carried out.
- Figure 1. Shows a block diagram of a method of manufacturing removable or fixed dental prostheses according to a first technique already known in the state of the art.
- Figure 2. Shows a block diagram of a method of manufacturing removable or fixed dental prostheses according to a second technique already known in the state of the art.
- Figure 3. Shows a block diagram of the manufacturing method of removable or fixed dental prostheses according to the present invention.
- Figures 4a), 4b) and 4c) Show as many views of a tooth, in this case a central incisor.
- Figures 5a), 5b) and 5c) - Show as many views of a tooth, in this case a lateral incisor according to the present invention.
- Figures 6a) and 6b) - Show as many views of a tooth, in this case a molar, according to the present invention.
- Figure 7. Shows a perspective view of a gingiva according to the invention, in which the extensions or male parts on which the teeth are mounted can be seen.
- a preferred embodiment for the method of manufacturing dental prostheses of the present invention comprises the following steps:
- This digital image can be obtained either directly with an intraoral scanner or by making a physical model of the mouth in plaster and then scanning it. In both cases, detailed information on the morphology of the patient's mouth will be obtained, which can be digitally managed in the process using the appropriate computer equipment and software.
- the digital design of both the gums is carried out (4) as well as the necessary dental pieces (1) that make up the functional and dimensional personalized dental prosthesis for said patient, where for the subsequent union of both they have tongue and groove means, specifically, the teeth (1) are designed in a that comprise a hole or female part (2) in their lower base (3) for attachment to the gum (4) and, for its part, the gum (4) is designed in such a way that it comprises the corresponding extensions or male parts (5 ) destined to receive each one of the teeth (1) specific for each position.
- the tongue and groove joints that is, the female parts (2) located on the teeth (1) and the corresponding male parts (5) located on the gingiva (4), are designed depending on the type of dental piece (1), its shape and functionality, that is, said joints have to be large enough to guarantee the hold between tooth (1) and gum (4) but without affecting the aesthetics of said teeth (1 ).
- each of the tongue and groove joints between each tooth (1) and the gum (4) vary for each case, being different for each type of tooth (1) depending on their mechanical stresses and their morphology as seen in Figures 4 to 7.
- the gingiva (4) designed for a typical patient will comprise a plurality of connections or male parts (5) emerging superiorly and which may all be different integers, or at least, different between each type of tooth (1) (central incisors, lateral incisors, molars, premolars, canines, etc.).
- the advantage that the male part (5) is located in the gum (4) and not vice versa has its reason in that for the gum (4) to receive a male-type connection from the tooth (1) in an adequate length, said female part would need in some cases to have to be inserted into the bone bed of the patient, which in addition to delaying and making the process more expensive, would obviously entail significant discomfort for the patient derived from the need to make holes for the accommodation of the female part in its bone bed.
- connection or female and male parts (2, 5) are designed so that said assembly is unambiguous, that is, that each tooth (1) can only be mounted in a single position on the corresponding male part (5) in the gum (4).
- Figures 4 to 7 show a possible embodiment of the invention in which the female part (2) present in the dental piece (1) and the male part (5) of the gum (4) have a conical half-round shape. which ensures that both can only be assembled in a single and unambiguous position, defined during the digital design stage, and therefore eliminates the possibility of alignment or placement errors when both parts are assembled to form the prosthesis.
- the teeth (1) and the gingiva (4) are manufactured separately. More specifically, according to a possible preferred embodiment, the gingiva (4) is manufactured, on the one hand, by means of a 3D printing technique using the appropriate materials and, on the other, the dental pieces (1) in acrylic material also preferably using a selective layer injection-compression molding (SCIM) process.
- SCIM selective layer injection-compression molding
- the assembly is carried out by tongue and groove between them which, thanks to the elements or male (5) and female (2) parts described above, is carried out quickly and without errors since they only allow mounting in a single univocal position.
- the tongue and groove joint between tooth (1) and gum (4) is reinforced with the use of a suitable cement, glue or acrylic resin that ensures a durable and reliable joint between the referred teeth (1 ) and the gingiva (4), greatly improving the performance of the processes currently carried out.
- the female parts (2) located in the teeth (1) have different dimensions depending on the type of tooth (1) where they are located, since these dimensions are dictated both by the shape of the dental piece (1) as its functionality, being necessary a greater section or tongue and groove dimension the greater its masticatory load and / or the mechanical forces or stresses to which it is subjected when it is operative on the patient's mouth. This, of course, also conditions the size of the male parts (5) of the gingiva (4) on which the corresponding dental pieces (1) will be mounted.
- both the female parts (2) of the teeth (1) and the corresponding male (5) and present in the gum (4) have a design that allows their tongue and groove in a single unequivocal position, having chosen for the examples shown in said figures that of a conical half-round shape, but it can be any other that fulfills that function and does not prevent a correct tongue and groove.
- either the inner surface of the female part (2) of the dental piece (1), or the outer surface of the male part (5) of the gum (4), or both, may have means grip such as small bumps, roughness, scratches, etc. that facilitate the action of a cement, glue or acrylic resin used to ensure a durable and reliable bond between the teeth and the gum.
