Description

CONCAVE AND CONVEX DENTAL RAKE Inventor: Daniel Cubillo Burón, of Mexican nationality, domiciled at Av. Insurgentes Sur No. 4031. Edificio Ottawa, Depto. 104, Colonia Santa Úrsula Xitla, Tlalpan, C. P. 14000, in Mexico D.F. EXTRACT The present invention refers to a dental rake, whose combination of parts that form it allow to replace the horizontal movement of traditional toothbrushes by an anatomical vertical movement achieving a complete and effective cleaning of the internal and external faces of teeth and molars, as well as massage of gums, tongue, palate and inner face of the cheeks, and consists of two heads that have a concave and convex curvature respectively, in which the bristles are, and these heads are interchangeable and are placed or incorporated to a handle by a simple pressure mechanism. One embodiment of the present invention consists of two rakes, one with a concave head and the other with a convex head, made in one piece, that is, said heads are not exchanged on a single handle.

BACKGROUND OF THE INVENTION It has been no less than 25 years that dental associations and dentists in particular require practically correct tooth brushing. A wide variety of toothbrushes are known in terms of size, curvature and design of the handles, number of rows of bristles, cutting of the bunches of bristles, different degrees of hardness of the bristles depending on whether they are natural or of synthetic materials. , but all of them agree that the head of the brush and the handle are collinear, forcing the user to perform a horizontal movement - usually fast - when brushing the teeth. Which is disadvantageous, because to dislodge food waste from the interstices of teeth and molars it is necessary to make a vertical movement by forcing the wrist, so that most people do not usually do it; In addition, brushes that are already known to move horizontally in a fast and violent way cause the gums to be withdrawn, and moving in this way is contrary to the enamel sense of the teeth. It is common for dentists to attribute many of our cavities and gum problems to poor brushing. These comments are extended to a supposed (or real) bad education that we give our children in regard to dental and oral hygiene. Now, what is it that dentists demand of us? 1. Vertical movement of brushing.- Dentists say that it is about following the anatomical design of the tooth as well as the enamel growth direction. 2. Turns.- Also, Dentiostas recommend to print to the brush small energetic turns so that the bristles expel residues of food from the interstices of the teeth and molars 3. Retraction of the gums. The turn mentioned in the previous point offers another great benefit. It consists of preventing the retraction of the gums, which exposes the ivory of the root, which causes real rows of decay along the length of the teeth. In addition, this rotation provides a massage in the gums and decongesting them, strengthening them and favoring good blood circulation. All this helps to avoid certain infections, one of them being pyorrhea. 4. Cleaning the wisdom teeth. - Dentists insist that the last molars, both upper and lower, be cleaned as much as possible, trying to rub the hidden part of the wisdom teeth, which are practically inaccessible. 5. Cleaning of the internal faces of the denture.- Dentists warn that if the internal faces of the denture are not cleaned periodically, it must be cleaned with the cavitron insert, in order to remove the tartar as well as the bacterial plaque. , which are again cause of tooth deterioration (detartragia). DOES THE TRADITIONAL BRUSH ENABLE TO FULFILL ALL OF THESE RECOMMENDATIONS? Analysis of the foregoing 1. Vertical brushing movement.- The traditional brush induces a natural horizontal movement due to the characteristics of its own design, which forces to achieve a vertical movement forcing shoulder, elbow and wrist. This is how these forced movements and the movement induced by the traditional brush design come into conflict. If this is a difficulty for adults, it should be taken into account that it results in "torture" in terms of habits of dental hygiene in a child. 2. Turns.- If the traditional design induces horizontal movement and vertical movement is forced, we agree that it is totally contradictory to a rotation; therefore it is necessary to achieve the rotation of the brush by forcing the wrist. Once again the design of the brush with the movements recommended by dentists is in conflict. 3. Retraction of the gums.- The previous point explains why a satisfactory massage on the gums can not be achieved either. 4. Cleaning the wisdom teeth.- With the traditional brush it is difficult to reach the faces, especially external, of the wisdom teeth and turn them around to clean the sides of the bottom of the cheeks. 5. Cleaning of the internal faces of the dentition.- With the traditional brush the cleaning of certain areas of the internal face of the denture is achieved. However, the area that is more dangerous from the point of view of tartar and plaque, corresponds to the internal part of the lower front teeth.

D2SCRIPTI0N DETAILED The object of the invention is to eliminate the drawbacks of these brushes by means of the concave and convex dental rake described herein, which by having two crosspieces or interchangeable heads, one concave and the other convex, and because these are placed perpendicularly in relation to the handle and by incorporating the heads by means of a simple pressure mechanism, it allows the teeth and molars to be cleaned on all their faces, adapting to most of the curves of adult or child dentures since the rake or concave head dislodges food waste from the interstices of the teeth and molars with efficiency similar to that of dental floss and reaches the wisdom teeth by turning them over, while the rake or convex head combats tartar and bacterial plaque on the inner side of the tooth. teeth and teeth also thanks to the curvature of the concave and convex heads follow the anatomical shape of the teeth and that the present concave and convex dental rake replaces the horizontal movement of the traditional brush with a vertical rake-like movement that is achieved by its design, consisting of the fact that the head or part where the bristles and the handle are perpendicular and not collinear as in the brushes already known. With both heads of the concave and convex dental rake, the movement follows the anatomical shape of the denture and the direction of the enamel that also grows vertically longitudinally, resulting in an effect totally opposite to that of the traditional brush that rubs the enamel transversely. In addition, the slow vertical movement of the concave and convex dental rake helps prevent the gums from becoming withdrawn and therefore the denture is not emaciated, exposing areas without enamel to caries or certain infections such as pyorrhea. Likewise, the concave and convex dental rake modifies the antiaatomic movement of the hand when using the traditional brush, by an anatomical vertical movement and forced by the own design and shape of the dental rake, all of which makes it more comfortable, easy to use, effective, practical and durable in its construction. The characteristic details of this concave and convex toothbrush are clearly shown in the following description and in the accompanying drawings, as an illustration of that and serving the same reference signs to indicate the same parts in the figures shown: Figure 1 shows the concave head, the convex head, the handle and the pressure mechanism by means of which the heads are incorporated in conventional perspective. With reference to said figures, this concave and convex dental rake is formed by three elements (Fig. 1, A, B and C) consisting of a concave head (B), a convex head (C) and a handle (A) . In more detail, the concave head (B) has the average curvature of the front of the denture and in the front or concavity it has a series of bundles of bristles (G) which are perpendicular to the base of the concave head (B) ) that is, following its curvature. This concave head (B) has downwards a straight stem (F) with a decrease (D) at the end and in it a small projections (H) to fit the handle (A). The convex head (C) has the average curvature of the internal part of the denture and in the front or convexity it has a series of bundles of bristles (G) which are perpendicular to the base or convex head (C) that is to follow its curvature. This convex head (C) has a rod (E) facing down with a curvature necessary to allow the desired row of teeth to be cleaned without crashing or clogging with the opposite row of teeth, and having a decrease at the end (D) and in it small projections (H) to fit the handle (A). The handle (A) is straight and has in the upper part a recess (L) with small recesses (J) to adjust the concave (B) and convex (C) heads and at the lower end it has a hole (K). All the edges of the concave and convex dental rake (Fig. 1) are rounded to avoid chafing. The concave (B) and convex (C) heads may consist of one or more rows of bristles (G), as hard or soft as desired; as thick or thin as you like, so as to achieve from a rake effect to a brush effect, from the idea of evicting food waste to the concept of massage of gums, tongue, palate and inner face of the cheeks.

The concave and convex dental rake (Fig. 1) can be made of plastic or other appropriate material, just like the bristles (G). The modality of the concave and convex rake (Fig. 2 A and B) is that each rake has its own handle. Its characteristics and properties are identical to that described above in the case of interchangeable concave and convex heads on a single handle. Samples have been made under many variants, and practice has indicated that the most viable prototypes are the subject of this patent. In practice it has been possible to establish an evaluation of the prototypes and observe that they did respond correctly to the analysis carried out for conventional brushes. 1. Vertical movement of brush.- The dental rake obliges, by its own design, a natural vertical movement. Therefore, the anatomy of the arm, of the teeth and the movement induced by the design of the rake, come into harmony. 2. Turns.- The design of the dental rake itself, including that with a single row of bristles, achieves the desired goal, within the vertical movement itself, without requiring any type of twist of the wrist. It is much easier to teach children how to brush their teeth because they have the right tool. 3. Retraction of the gums.- If the horizontal brushing movement causes contraction and retraction of the gums, it turns out that the dental rake, by its own design, does not allow "frantic" movements and in the process leads to the desired result, which consists of in attracting as much as possible the gums towards the tooth. In addition, it has been observed that in the first brushes with the dental rake are caused, without violence, small hemorrhages that decongest the gums.

Claims (1)

1. 4. Cleaning of the wisdom teeth.- With the dental rake it has been possible to observe the following: by the vertical "forced" movement and the curvature of both the concave and convex head, easy access is obtained to the wisdom teeth, being able to "turn them around". 5. Cleaning the internal faces of the teeth.- In the dental rake, the convex head has been designed to comfortably clean the internal faces of the teeth and teeth in their entirety, in a deep and pleasant way. It is worth mentioning the benefits that the constant use of the dental rake would bring to the general health of its users, by eliminating the negative consequences of inadequate oral hygiene. Having described the invention, it is considered as a novelty and, therefore, the content of the following is claimed as property: CLAIMS 1.- A concave and convex dental rake that is formed by three elements consisting of a concave head and an interchangeable convex head on a single handle. Also, this rake can be replaced by two rakes, each with its own handle, these two rakes being equivalent to the three-piece rake described above. 2. A concave and convex dental rake in accordance with that claimed in Clause 1, characterized in that the concave head has the average curvature of the front of the denture and in the front or concavity has a series of bundles of bristles perpendicular to the base or concave head following its curvature. 3. A concave and convex dental rake in accordance with that claimed in the previous clauses, characterized in that the convex head has the average curvature of the internal part of the denture and in the front or convexity has a series of bundles of bristles perpendicular to the base or convex head, that is, following the curvature. 4. A concave and convex dental rake in accordance with that claimed in the previous clauses, characterized in that the concave head has a straight stem downwards and the convex head also has a rod but with a curvature necessary to allow the cleaning of the row of teeth. desired teeth without crashing or clogging with the opposite row of teeth, and because said ends at the ends have a decrease and in them small projections to fit the single handle under pressure. This description is equally valid in the case of replacing the interchangeable heads on a common handle with two rakes, each one in one piece, one of them having a concave head and the other with a convex head. 5. A concave and convex rake in accordance with that claimed in the previous clauses, characterized in that the handle is straight and has in the upper part a recess with small recesses to adjust the concave and convex heads under pressure when the heads are interchangeable, and at the lower end it has a hole to be hung. 6. A concave and convex rake in accordance with that claimed in the previous clauses, characterized in that all its edges are rounded to avoid chafing, because the concave and convex heads can consist of one or more rows of hard or soft bristles and because it can be of plastic or other appropriate material, like bristles. 7. A concave and convex rake in accordance with that claimed in the previous clauses, characterized in that it follows the anatomical shape of the denture and because it replaces the horizontal antiaatomic movement of the arm and the hand, by an anatomical vertical rake movement, which it is achieved forced by the own design and form.
