Description

The present invention relates generally to the design and use of tooth and gum cleaning instruments. More particularly, the present invention relates to the design and use of an improved toothbrush appliance for cleaning teeth, gums and / or orthodontic appliances.
(Cross-reference of related applications)
This application was filed on Nov. 13, 2007, US Provisional Patent Application No. 60/987410, filed Apr. 15, 2007, No. 60/911899, and filed Mar. 19, 2007. No. 60/895683, No. 60/895669 filed on Mar. 19, 2007, No. 60/987409 filed on Nov. 13, 2007, No. 60 filed on Oct. 12, 2007 No. 9/97405, and 60/911901 filed Apr. 15, 2007, each of which is hereby incorporated by reference in its entirety.

  Those who are not using fixed orthodontic appliances will feel that a conventional toothbrush is sufficient to remove plaque. However, orthodontic patients using braces and other fixation devices face unique problems when removing plaque around these appliances and their surrounding teeth and gums, i.e. gums. . For these types of patients, the level of plaque removal is acceptable because a fixed orthodontic appliance does not reach the area around and underneath the appliance where plaque accumulates, with conventional toothbrushes. It is not unusual to be not. Thus, in order to properly remove plaque using a conventional toothbrush, considerable manual dexterity is required for that part of the patient. Inadequate dental care can result in various forms of caries. Accordingly, there is a need for a toothbrush that can remove plaque that is inaccessible or difficult to reach with a conventional toothbrush at home or in a dental hygienist's clinic.

Furthermore, the various areas of the mouth require different types of cleaning. Various teeth and gum locations in the mouth, eg, mesial (eg, located along the curve of the dental arch towards the center of the front of the jaw), centrifugal (eg, for teeth or tooth surfaces) , Located farthest from the center and front of the jaw), adjacent surfaces (eg, tooth surfaces facing the centerline of the palate), between adjacent teeth (eg, between adjacent surfaces of adjacent teeth), Between teeth (eg, between adjacent faces of the same dental arch, or in relation to them), etc. can benefit from different brush structures. Gingiva, or gums, is divided into marginal areas (eg, surrounding the teeth), attachment areas and interdental areas, each with different problems in exposing and approaching.
Current interdental brushes are specialized instruments designed only to clean between teeth by pushing flat protrusions between the teeth in a manner similar to using dental floss. When the orthodontic appliance is in place on the teeth, an interdental brush can be inserted. However, such interdental brushes are only somewhat effective in cleaning and do not reach the full area of the teeth and gums. Furthermore, such brushes cannot clean the periphery and the interior of orthodontic appliances. Conventional adjacent brushes are less effective due to the presence of orthodontic appliances such as dental braces that attempt to clean the outside of the tooth surface and bend or displace the bristles. Hinders or at least reduces the cleaning of and around it and the affected teeth and gum regions.

Luposello, US Pat. No. 5,537,708, discloses one known toothbrush used to clean orthodontic appliances, including a head having a plurality of upwardly extending bristles. Two elongated brush members overlap vertically on the bristles. Both elongate brush members include an unattached end for insertion between the orthodontic wires and an opposite end connected to the handle of the toothbrush. Luposello is an upwardly extending bristle that combines any of the upwardly extending bristles with horizontal or vertical extension within the same cleaning surface, with any upwardly extending bristles demonstrating omnidirectional cleaning ability. Also not disclosed.
Massetti U.S. Pat. No. 4,317,463 discloses another known toothbrush with a handle having a cleaning portion at one end thereof. The cleaning portion includes opposing side members having one or more swabs extending laterally therebetween. The swab member is rotatable and includes a plurality of bristles extending therefrom. Massetti describes such a rotatable swab and does not consider the use of non-rotating cleaning elements. The rotatable cleaning element slides on the surface to be cleaned, such as the surface of a tooth or orthodontic appliance. Rotating makes them easier to bend rather than keeping the bristles relatively straight. The bristles bend and do not reach the pockets between the teeth for a complete clean. In addition, the bristles rotate to effectively contact the teeth and surrounding tissue / space and form a curve around the teeth rather than clean them. Furthermore, the rigid side members that hold the swabs with laterally extending bristles are more elastic, i.e. elastically, to orient the bristles between the teeth, gums and orthodontic appliances. It is less efficient than a deformable toothbrush holding an element.

  Certain embodiments provide a dental, orthodontic appliance, gingival (gum), tongue and / or cheek cleaning appliance. Certain embodiments include a plurality of bristles that are arranged to contact the surface of the teeth and gums, and further travel around and below braces or other orthodontic appliances without departing from the orthodontic appliance. Provide mouth-cleaning equipment. Non-rotating cleaning elements are more suitable for cleaning teeth, gums, other mouth tissues (eg, tongue and cheeks), and orthodontic appliances, where the cleaning element is on the surface to be cleaned. Not slipping is at least part of the reason. Certain embodiments provide a cleaning device that reaches teeth, gums, tongue, cheeks and orthodontic appliances in adjacent surfaces, adjacent teeth, between teeth and / or other areas. The cleaning element may be used to clean teeth, tongues, cheeks and gums, and for example during wires, undercuts and / or other areas of orthodontic appliances (such as dental braces) Reach inside and / or around it.

  The cleaning implement may be configured to include a cleaning portion, i.e., a head and a handle. The head and handle can be connected by a neck, for example. In certain embodiments, the cleaning instrument handle and head are formed using conventional injection molding techniques. In certain embodiments, the cleaning implement may be made from a plurality of components. Bristles and / or other cleaning elements may be attached to the head by gluing, binding, stapling, thermoforming, melting, welding, and the like. The cleaning element, head and handle may also be formed together using, for example, a single-step or multi-step injection molding process.

In certain embodiments, the bristles and / or other cleaning elements in the instrument head may be formed from a thermoplastic material such as wire strands, microfibers, copolymers or synthetic polymers (eg, nylon or polyester). The thickness and / or length of the bristles and / or other cleaning elements may be varied based on, for example, the desired mouth contact area, abrasion due to cleaning, and / or other criteria. In various embodiments, several cleaning elements can be provided, such as primary, secondary and / or multidirectional cleaning elements.
In certain embodiments, brushing or cleaning elements such as bristles contact the area around and below the orthodontic appliance, such as a dental brace, without deviating from the brace. In certain embodiments, bristles are used around the teeth and / or in order to access and clean the inaccessible parts of the teeth, tongue, cheeks and gums in the mouth for the purpose of removing plaque and other deposits. Or reach the back side. The brushing head is configured to reach the entire tooth in order to contact tissue and tooth surfaces within the oral cavity, for example, on the back side of the molar, and to clean the orthodontic appliance.
In various configurations, many of which are described below, the cleaning element formed in the head portion is substantially or substantially curved formed by a center / neck around which the bristles extend radially. Arranged in an arcuate or angled U-shape or V-shape can form a generally annular cleaning element. The center / neck is attached to or attached to the handle. The cleaning head may be implemented at various angles. The cleaning head may be in the same plane as the handle portion of the instrument and / or may be located in a different plane (eg, extending a certain angle above and outside the handle). In certain embodiments, angles may be employed in the head to form cleaning elements in multiple planes of the head portion. For example, the proximal portion of the head may be disposed in substantially the same plane as the head portion, and the distal portion of the head is inclined upward relative to a plane that is substantially parallel to the face of the distal portion of the head.

  Specific embodiments describing variations of mouth cleaning device design and utilization are provided in more detail below.

The mesial-centrifugal cleaner The molars (the teeth located behind the mouth) and the associated gums, as well as the mesial and / or distal regions of the edentulous (ie, missing or missing teeth) part of the mouth are clean It is extremely difficult to do and is therefore prone to periodontal disease. Commonly available toothbrushes are difficult to clean such areas of the mouth, even using different bristle heights and bristles of various angles. Current interdental brushes and conventional toothbrushes are not effectively designed to clean such problem areas. Certain embodiments are designed to improve the distal region of the teeth at the end of the dentition (ie, the array of teeth in the mouth), and the mesial and distal regions of the edentulous part. -Provide a centrifugal cleaner. For illustrative purposes, FIG. 1 provides an example of the distal region of the molar and the mesial and distal regions of the missing tooth, ie the edentulous part of the mouth.

The mesial-centrifugal cleaner 200 includes a head 210, a neck 220, and a handle 230. The head 210 can be, but is not limited to, for example, a twisted wire brush, cylindrical brush, or plastic or rubber material having bristles or similar cleaning elements extending from the center in a generally annular arrangement. It includes a central portion having bristles protruding in multiple directions, such as other similarly shaped devices. FIG. 2 shows some examples of mesial-centrifugal cleaner devices according to certain embodiments of the invention. As shown in FIG. 2, the instrument 200 has a portion of the head 210 (denoted as “A” in FIG. 2) perpendicular to the long axis of the handle 230. Portion A of head 210 is used to clean the mesial and distal regions described above (eg, as shown in FIG. 3). The head 210 also helps to reduce contact between the teeth and the center and can be used to clean the front tooth tongue area (eg, the tooth area proximate to the tongue as shown in FIG. 4). (Indicated as “B” in FIG. 2). As shown in FIG. 5, the appliance 200 reaches the distal surface of the tooth, the gum tissue near the distal surface of the tooth, and between the gum tissue and the distal surface of the tooth. The device 200 can also be used to clean the tongue and / or cheek surfaces. FIG. 6 demonstrates that the user can fold the neck portion 210 of the cleaning device 200 to easily access the difficult-to-access areas of the teeth and gums and make brushing more comfortable.
In operation, for example, the user grasps the handle 230 of the cleaning device 200 and uses both part A and part B of the head 210 to reach and clean various areas of the teeth and gums. . The bristles in the head 210 can contact the teeth, for example, for the purpose of cleaning the surface of the molar tooth and the tissue behind it. As shown in part A and part B, such cleaning is performed so that the configuration of the bristles extending radially around the center of the head 210 and the branches of the head 210 is beneficial to the user. To help promote.

Certain embodiments of the mouth cleaning device provide a variation on the mouth cleaning device. Mouth cleaning device (MCD) 700 includes a head 710, a neck 720, and a handle 730. The head 710 includes a central portion having bristles protruding in multiple directions, such as a wire brush, but is not limited thereto. The wire brush can be replaced with, for example, a cylindrical brush or other similarly shaped device made of rubber or plastic material.
FIG. 7 shows an exemplary MCD 700 that includes a head 710, a neck 720, and a handle 730. 8, 9 and 10 describe views of the head 710 as viewed from FIG. 10c, as viewed from FIG. 7b, respectively, as viewed from FIG. 7a. 8, 9 and 10 show examples of various configurations of the MCD 700. FIG. The length of the bristles can be uniform or can be variable, for example, to facilitate proper access to the area between the teeth, around the braces, and between the teeth and gums. The wire brush can be folded so that the bristles are more easily accessible to the tooth surface, the area between the teeth and the gums. FIG. 11 illustrates various applications of MCD 700 for cleaning teeth and gums, for example.

  The neck 720 connects the bristle portion, ie the head 710, to the handle 730. FIG. 12 demonstrates that the two ends of the wire brush can be joined together before the brush head 710 is embedded in the handle 730. FIG. 13 shows that the two ends of the wire brush can be embedded in the handle 730. FIG. 14 shows a configuration of an appliance 700 where only one end 720 of the wire brush 710 is embedded in the handle 730 and the other end can be adapted to other tooth cleaning appliances. In FIG. 15, the interdental toothbrush 740 is configured to have a shorter bristles and to be the tip of the unfastened end of the MCD 700. The interproximal toothbrush portion 740 may be made of thinner wires and / or bristles having different stiffnesses and / or lengths, for example. An example of another additional cleaning instrument is shown in FIG. FIG. 17 demonstrates that the neck 720 can be straight, curved, or bent to connect the head 710 to the handle 730 in various directions. The length of the neck 720 can vary, which can appear as an extension of the handle 730, for example. The handle 730 may be straight or curved for ease of use, as found in commercially available toothbrushes. FIG. 18 shows a variation of MCD 700 in which two parallel wire legs 712, 714 do not connect at the tip.

  In certain embodiments, the head 710 and / or neck 720 can be adjusted or bent by the user to achieve the comfort and / or efficiency he or she chooses. For example, the wire portion of the head 710 may include plastic protective material and / or other coatings to reduce discomfort and / or protect teeth or soft tissue upon contact.

In operation, for example, the user grasps the handle 730 and uses a plurality of bristles extending along the length of the head 710 to access the oral cavity to access the teeth, tongue, cheeks and / or gums. The head 710 is skillfully operated within. The configuration of head 710 allows the user to access and clean adjacent interproximal regions of the teeth, gums and cheeks, and other regions in the oral cavity, including in and around orthodontic appliances. It becomes possible.
Wire Twist Brush Loop Toothbrush In certain embodiments, a wire twist brush that can be bent to a commercially available toothbrush so that it is more easily accessible closer to the arch of the upper and lower front teeth and the back of the final molar A (WTB) loop is added.
In certain embodiments, a WTB loop 1910 can be attached to the toothbrush head 1920 as shown in FIGS. 19 and 20. A three-dimensional diagram is shown in FIG. As shown in FIG. 19, the loop 1910 may be configured to move and be adjustable to various positions relative to the brush head 1920 to contact a desired area in the mouth.
In certain embodiments, the WTB loop 1910 can be easily bent with finger pressure. Depending on the placement of the WTB loop 1910, it is possible to more easily approach a specific area of the mouth.

As an example, FIG. 38 shows a first embodiment in which the WTB 3410 is disposed in a recess or indent 3460 in the body 3420 and a second embodiment in which the WTB 3410 is disposed behind the protrusion 3470 of the body 3420. Show.

  In certain embodiments, the mechanism for attaching WTB 3410 to body 3420 may be fixed and / or removable. In the fixed mechanism, the bristles-free end of WTB 3410 is embedded in toothbrush body 3420. In a removable mechanism, the WTB 3410 can be attached to the body 3420 via a male / female connection (see, eg, FIG. 39). Other removable securing mechanisms can be used.

  In certain alternative embodiments, the embedded end 3430 (without bristles) of the WTB 3410 is mechanically secured within the body 3410 so that the end 3430 does not move when the WTB 3410 is bent back and forth. An example is shown in FIG.

In certain embodiments, other types of auxiliary tooth cleaning appliances can be attached to commercially available toothbrushes in the manner described above. An example is shown in FIG.
In operation, for example, bristles on the brush body 3420 can be used to clean teeth, gums, and other areas in the oral cavity. A WTB 3410 can be placed in the user's mouth to additionally clean between and around the teeth, orthodontic appliances, tongue, cheeks, and the like. Thus, the body bristles and the wire brush are complementary to each other to achieve complete cleaning.
