Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to dental cleaning, and more particularly to dental cleaning, and more particularly to dental cleaning, and more particularly to dental cleaning, and more specifically to dental cleaning, and more particularly to dental cleaning, and more particularly to dental cleaning, and more specifically to dental cleaning, and more particularly to dental cleaning, and more particularly to dental cleaning, and more specifically to dental cleaning, and more specifically to dental cleaning, and more particularly to dental cleaning, and more particularly to dental cleaning, and more particularly to dental cleaning, and more particularly to dental cleaning, and more particularly to dental cleaning, and more particularly to dental cleaning, and more particularly to dental cleaning, and more particularly to dental cleaning in various configurations designed for improved cleaning of the mouths of a wide variety of individual patients in the setting of increased edentulism. Relating to a system for providing toothbrushes.

×Oral hygiene instructions to be used in the garden Over the years, dental professionals have taught that it is advisable to use a hand brush for 8 minutes to debride the mouth and at the same time break up bacteria-laden tartar. Generally recommended.

With the use of a power toothbrush, this time can be reduced to 4 minutes by power motion.

However, whether by power or manual method,
Areas where many problems occur in the oral cavity (intradental area)
Inserting brushes into terproztmal areas requires the correct brush design.

It is desirable to use brushing (br%giLing) to remove as much bacteria-containing tartar as possible from the interdental spaces and below the free gingival margin, as well as from the tooth surfaces; The bacteria in the calculus, which is responsible for the deterioration of the gums, is in the form of calculus/9 by isolating the cutaria from their groups, i.e. preventing the calculus from forming on the teeth and destroying the group formation of bacteria. It has recently been recognized that it can be rendered inactive for up to 24 hours. Therefore, the teeth are brushed with a rotary movement parallel to the occlusal plane to slow down the free gingival margin rather than in an up-down interlock, and such rotational movement also reduces the structural erosion of the tooth caused by up-down brushing. (strsC cre erosion)
It is emphasized that this should be avoided.

The construction of currently available toothbrushes neither facilitates the use of the desired rotational motion nor provides a means to facilitate access into the interdental spaces and free gum line, parallel to the occlusal plane. To provide a toothbrush that not only discourages rough brushing and encourages and facilitates the desired rotary brushing motion, but also provides a means for bacterial fluid to reach interdental spaces and free subgingival margins. There is currently a lot of decoration.

Several proposals have been put forward to provide increased access to the interdental and free external gingival margins of the teeth. The most important of these is U.S. Patent No. 4209.8 for Ernε8t.
No. 71, which patent is incorporated herein by reference. U.S. Pat. No. 4,209,8, cited above? No. 1 discloses a toothbrush with a head that provides increased access to the teeth, but the characteristics of the brushes mean that it is difficult to provide brushes in a wide variety of configurations. For example, some stores sell different hand toothbrush handles and electric toothbrush handles in various combinations, such as those that can be paired with various types of bristles, various degrees of stiffness, and various sizes of heads. must maintain different inventories. Therefore, with a relatively large mouth, Bro
Patients who have a zident(TM) electric toothbrush head and who desire soft, round-tipped natural bristles will likely not be satisfied with a toothbrush used in small hands that has stiff nylon bristles with a cropped tip.

Additionally, a good home dental program (Aomgden
tal program) features the use of different toothbrush designs. For example, if a patient brushes twice a day, he or she brushes the gum area in the morning.
Use a brush that maximizes eαning),
You may also wish to use a brush to maximize cleaning of the interdental areas before going to bed. Once upon a time,
A dentist may wish to instruct the use of a specific type of toothbrush, such as a toothbrush designed to treat certain periodontal disorders.

,-The main function of a toothbrush is to clean,
It is well known that toothbrushes are perishable due to their properties. Micro-particles and fine particles often remain between the bristles. Similarly, in a moist environment, the bristles often tend to remain damp and rotten at room temperature for long periods of time between uses of the toothbrush.

People have used various methods to prevent putrosive conditions. In addition to harshly rinsing the dental plan before and after each use, multiple toothbrushes are used that allow for long periods of inactivity between uses of a particular toothbrush. Septic conditions have also discouraged the use of toothbrush designs that use large amounts of bristles, as these large amounts of bristles make it difficult to keep the toothbrush head dry. be.

Various disposable toothbrush designs have been submitted in the prior art. Prominent among these is U.S. Pat. ing.

The above-mentioned patent W-f No. 4.227.276 discloses the use of a removable handle that can be shaped into any shape when heated in hot water. This provides a partial solution to another problem in the prior art, which is the customization of toothbrush handles for individual users.

Although a toothbrush handle of a particular shape is more desirable, it would also be desirable to provide a toothbrush handle, especially in a highly specialized or expensive variety, having a disposable brush. For example, if the user is spending the night at home,
When desiring to use a brush, the user will want to have the convenience of portability. Users may also desire a proprietary toothbrush bed configuration that has the convenience of use.

When a user is visiting, if someone she knows has an electric toothbrush nondle, she can use the electric toothbrush to keep her toothbrush reasonably sterile if the environment is deceiving. It may be desirable to have an I-endle that allows attachment to the noondle.

U.S. Pat. No. 3,994,039 discloses various methods of brushing teeth, which patent is incorporated herein by reference. These two methods include various combinations of forward and vertical brush movements designed to effectively clean teeth.

Similarly, electric toothbrushes have been designed to provide a variety of brushing motions, primarily in an attempt to provide the brushing motion recommended by dentists. These include, in addition to vertical and horizontal motion, combinations of vertical rolling motion and horizontal and rolling motion. Recently, short circular motions have received wide acceptance in dentistry. These different motions have generally been designed for use with a single brush, usually having a single rectangular or circular shape, with little attention paid to improving the brush design.

Therefore, it is an object of the present invention to provide a handle that can be configured in different ways.
- A system for permitting the use of an improved toothbrush design in a wide variety of toothbrush environments, including in-person toothbrush trays, in dental applications, and in environments away from the home. The goal is to provide the following.

Another object of the present invention is to provide a system for improved dental hygiene in which improved heads can be used that are easily convertible either with different heads or with clean heads.

Yet another object of the present invention is to provide a modified plush head for removably attaching to the handle for imparting various angles and positions to the head relative to the user's grip. The objective is to provide a toothbrush system that can. For example, the brush head can be tilted 1'801i on the handle, so that either a left-handed or a right-handed user can use the brush. This allows people with serious minimal dexterity problems, such as those with arthritis, the elderly, or the disabled, to use the brush with either their right or left hand.

Yet another object of the present invention is to provide a wide variety of handle holders, including manual handle holders, electric toothbrushes, portable handle holders, and handle holders that can be used only by hand or attached to an electric toothbrush. An object of the present invention is to provide a toothbrush having an improved head that can be used with a variety of handle ruders.

Yet another object is to provide a wedge-shaped toothbrush head configuration that is made acceptable by reducing the stiffness of the bristles at those points of primary contact with the gums and the gingival border areas of the teeth.

Yet another object is to provide a wedge-shaped toothbrush that is more acceptable to patients because they can cut out the conventional head into a 44 (!) shaped plan head.

Another uninvented purpose in history is to contrast the interconjunctival space and below the free giugival margins, make it sized to fit, place it in position 1a, and The bristles of the river bank are ft-width thick, and this creates a lingual cavity (l) where the accumulation of tartar is comparatively large.
Ingu, al cavity) and molars and premolars from the oral cavity. It would be advantageous to provide a self-brushing paulownia body having bristles that are particularly adapted to promote the desired rotary brushing motion while making it possible to brush the teeth on both sides of the arch.

In one aspect, the invention contemplates a handle having a tip extending from the handle and terminating in an attachment means for attaching a bristle retaining head having a major axis perpendicular to the longitudinal axis of the handle portion. There is. The bristle-retaining head is formed as a flat back from which a plurality of embedded bristles project in a predetermined array symmetrical about the lateral short axis of the head. There is. The bristle distribution, which can be packed into tufts of the '4i type, has a wedge-like form of such tufts with one of the tufts arranged as an adjacent top at each opposite end of the bag. The length of the head along the main axis is such that the bristles, including the apex, are spaced a certain distance apart, and the handle is in the occlusal plane when the mouth is in the open, toothbrushing position through handle operation. When placed along the teeth, it simultaneously facilitates the penetration of the bacterial fluid into the interdental spaces and free gingival margins of the teeth of both the maxillary and mandibular arches. The tuft forming the top of the simulant can be centered against the rounded end of the head on the main axis, or if the end of the head is tapered, the tuft may be
The tufts forming Li* are arranged along the rear or front side edges of the head. The transverse form of obliquity away from each apex accommodates the 5 callop contour of the gingival margin, thereby improving the ability of the bristles to penetrate below the free margin of the gingiva, while protruding at the gum line. Improves the ability of these bristles on the apex to penetrate into the interdental space.

The area of setae adjacent to the short axis of the head bristles is the wedge-shaped region of the head containing setae within the cluster of paddy, in order to facilitate the bending of the cluster when achieving these simultaneous penetrations, with the intention of being described below. These bristles placed on both ends can be cut to shorter lengths.

The modified hourglass-shaped head is kept parallel to the occlusal plane to give the toothbrush an additional ability when the main axis of the head is particularly pulsating when cleaning anterior teeth during gingival intrusion. ij along the head front and failure
Transverse-shaped bristles and tufts are provided at the l septum.

Other types of heads have also been provided, such as porosity rectangles with semi-circular ends, wedge and inverted wedge shapes, and gingival serge heads.

When viewed from the front, the bristles exhibit a gentle curvature from the center to approximately the fourth row of bristles. The disassembly attachment means can be designed as a fraction grip, bolt actuation, screw actuation, clip actuation slide or lock actuation. This attachment of the head to the handle can be designed in such a way that it can be inserted into the handle with a 180JJ turn or, conversely, with the horn of the hashidor reversed. .

Therefore, in other respects, an improved cacce-ssabi injection to the interdental and free gingival margins of the teeth.

Ig+ refers to a toothbrush structure comprising a transverse shape with two heads and a top at both ends, the handle of which is located near the lower part of the hourglass-shaped profile (top IMl). Attaches to the head (and can be removed from it), so the head can be easily removed and attached to other heads with the same hourglass shape or 1111 shape.
Can be exchanged. Different plug handles can be substituted for the handle so that the toothbrush can be used with a powered front brush handle or a manual brush handle.

In yet another aspect of the invention, a toothbrush of the type having an hourglass shape with bristles having serpentine sections extending from both ends of the hourglass, in the handle extending from the central part of the hourglass l'', is provided in the head holding the bristles. This has been improved by providing removal means for the head, thereby allowing modification of the head for increased sterility and for use with a variety of heads and handles.

In yet another aspect of the invention, a modular brush system is provided in which a variety of handles can be selectively attached to a number of brush heads, at least one of the heads having a sand-time shape. It has a contour of , so that different heads can be selected according to the user's different dressing characteristics and arranged on the head to maintain sterility when brushing.

1 to 3, the basic form of the toothbrush structure according to the present invention includes a handle portion 13, to which a removably acidic brush head 15 is attached as described below. I'm getting kicked out.

In the preferred design, the brush head 15 has an hourglass-waisted shape with a narrow h:1 minute 17 between the two flared portions 19.

The handle portion 13 extends from the narrow portion 17, thereby creating a somewhat vertical arrangement between the brush head 15 and the handle 13.

The handle 13 has a divine arrangement to make brushing easier. Near the illustrated gallery is a series of ridges.

Referring to FIGS. 1 and 61 in the preferred embodiment, the brush head 15 has two peaks 43 extending from a wide fc section 19 and a convergent section 45 extending from a narrow section 17. It is formed by the bristles 41. This allows improved access to the gingival margin and exposed adjacent teeth as well as the interdental areas, thereby allowing for ``brushing rather than brushing'' for pine surge and cleaning in these areas. It relies on the structure of

This brush configuration allows users to reach both interdental spaces and free gingival margins.

Historically, this brush allows the user to choose whether to clean the upper and lower teeth at the same time, especially in the dorsum of the arch, or to clean the upper and lower teeth separately.

C Yu quits the club in response to this attempt.43) Well,
The W is set correctly so that the user can quickly create a charcoal fire between the bacteria above and the source below. Therefore, it is possible to destroy tartar caused by this bacteria. The 411 bacteria that are destroyed are the ones that cause tooth decay.

The general shape of the head 15 is that of an hourglass-like waistband with more bristles in the wide areas 19, corresponding to the gingival areas of the patient's upper and lower jaws.

A preferred embodiment of a "standard size" head has a dimension of 14 mm in the widened portion 19. The narrow part 17 of the waist like an hourglass is lOs.
The + dimension is on the shoulder. The overall width of the head 13 is 24m
It is. The swollen area corresponding to the gingival area 199-3
Contains two vertical rows of tufts of setae. The narrowed part also has three vertical rows of bristle tufts. The width of the widened portion 19 follows the curvature of the hourglass and includes four rows of tufts each. The narrowest part (ie, the central part) consists of three rows of tufts each. The widened part has 111 tufts of hair with a length of 10 m. The narrowed portion 17 has a length of 8 mm.

It has a dark blue outer shape that ends at the most sieving position of i, and continues horizontally from the last dimension to 35 sieves. This handle 13 can be provided in stainless steel or plastic.

Referring to Figure $1 and Section 41, certain bristles 47Fi-
are chosen as the next contact bristles. These primary contact bristles 47 are on the periphery of one rasping surface at the top 43;
Therefore, it is possible to easily contact the tooth and gum surfaces before the other parts of the bristles 41. If all bristles 41 have the same stiffness or modulus of elasticity, then the primary bristles 47 will likely be able to exert the highest force on the patient's mouth, which will cause the secondary contact bristles 47 to form an extremely stiff indentation. part 4
The abrasion effect equivalent to the abrasion effect of the bristles in No. 5 is added.

To increase light contact for any given bristle thickness, the sub-contact bristles 47 are made more beamy than the other bristles, as described in the examples below.

The fVJ shaped nylon bristle toothbrush of Figure 5 is made of nylon bristles, most of which have a zero thickness to reduce the abrasive properties of these bristles on the free gingival margin area. .25 trrm, and the second contact bristles 47 are made 0.20 mu thick.

In situations where the patient does not wish to switch over to a new type of brush head, the patient can use a 51'' brush head of the design of Rutobi Shumei shown in Figure 7. As shown, the brush head 51 of conventional design also includes a paddle attachment 77, which is attached to the preferred hourglass-shaped brush "ped 19 mounting portion 2.

If this is possible and necessary, the user is guaranteed a clean brush head for one use. This not only makes it possible to use a brush head with a preferred design, but also allows Elijah to use a brush head with a preferred design. to QJ Noh.

Referring to Figure 4A's 8, a handle 55 is provided for attachment to an electric toothbrush handle (not shown).

The handle 55 has an attachment portion 29 that is identical to the attachment portion on the handle 13.

This makes the compatibility of handle 13.55 with brush head 15.51 +=J-enabled. The handle 55 includes a handle 57 for attachment to the particular toothbrush handle for which the handle 55 is designed.

6. #i Double toothed recess 59 allows use of handle 55 in locations where electric toothbrush heads are not available or cannot be plugged into a suitable power source.

However, it will be readily appreciated that by using the handle 55, the user does not need to purchase a complete toothbrush head, especially for using an electric toothbrush. This is a serious matter, especially where the user, for social reasons, does not want to show that the whole toothbrush was purchased for use on someone else's toothbrush handle.

Referring to FIG. 9f, the brush head can be provided separately from the handle in a conventional Glister package 61. In the illustrated Nogku-Solo 1, two types of brush heads 15.63 are shown, however, the configuration of the bristles is specific to the particular selection of the 11 brush heads. An indicia 65 on the package indicates that the bristles 41 are of special construction, facilitating selection at the time of betting. 1. The brush head can be attached to any handle with many types. The @ person is not limited in any way by the choice of pattern.

Providing a disposable brush head eliminates the need for the user to carry a tube of toothpaste. Particularly during travel, toothpaste poses a problem of inconvenience even when it is in the user's suitcase and no toothpaste remains in its tube.

To this end, the toothpaste can be provided with a brush head, as implied by the indicia 65 in FIG. 9.

Although the invention has been described with respect to specific embodiments shown in the figures, it will be obvious that various modifications may be made to the invention.

For example, the embodiment of FIG. 4 also has the potential to be useful with a conventionally designed fc toothbrush or with a handle that extends to an electric toothbrush.

As mentioned above, the preferred interdental brush head is not limited to the configuration of plan head 15 of FIGS. 1-4. 10-11, a wedge-shaped head 71.73i is formed with primary contact bristles 47' extending across the top in four rows in various tuft patterns according to the manufacturer's convenience. I can do it. Further, referring to FIG. 11, by providing a reduced thickness t for the primary contact bristles 47' in PJ4' tar 7 s, the intermediate bristles 77 between the tops can be provided without the narrow tuft configuration. can.

Is this still brush head 7373? j! Advantageously, the brush spatula door 1,73 has the contour of the brush head 63 (No. 91J) to provide improved contact with the interdental space and the gingival area.
