The disclosures herein relate generally to apparatus for cleaning mammalian teeth, and more particularly to a dental cleaning apparatus that is easily used to clean the different surfaces of mammalian teeth.
In one embodiment, a dental cleaning apparatus is disclosed that includes an elongated member having a brush portion and a handle portion respectively situated at opposed ends of the elongated member. The dental clearing apparatus also includes a plurality of bristle arrays situated approximately equiangularly spaced about the brush portion of the elongated member, each bristle array of the plurality of bristle arrays exhibiting a different bristle array geometry, each bristle array geometry being shaped to brush a different type of tooth surface.
In another embodiment, a dental cleaning apparatus is disclosed that includes an elongated member including a brush portion and a handle portion respectively situated at opposed ends of the elongated member. The dental clearing apparatus includes first, second and third bristle arrays situated at approximately 0°, approximately 120° and approximately 240° about the brush portion. The dental clearing apparatus also includes first, second and third tactile feel regions situated at approximately 0°, approximately 120° and approximately 240° about the handle portion. In this embodiment, the first tactile feel region is aligned with the first bristle array in a first plane. The second tactile feel region is aligned with the second bristle array in a second plane. The third tactile fee region is aligned with the third bristle array in a third plane. In this embodiment, the first bristle array and the corresponding first tactile feel region both exhibit a convex geometry. The second bristle array and the corresponding second tactile feel region both exhibit a concave geometry. The third bristle array and the corresponding third tactile feel region both exhibit a flat geometry.
The appended drawings illustrate only exemplary embodiments of the invention and therefore do not limit its scope because the inventive concepts lend themselves to other equally effective embodiments.
Mammalian teeth include surfaces with varying surface geometries depending on their position in the mammal's mouth. For example, front teeth may include convex anterior surfaces and concave posterior surfaces, while rearward teeth may include relatively flat anterior and posterior surfaces together as well as chewing surfaces.
The following is a list of elements that are referenced in
For example, rearward tooth 5 includes a substantially vertically flat anterior surface 5A, a substantially vertically flat posterior surface 5B and a chewing surface 5C extending therebetween as shown in
In another example, upper rearward tooth 2 includes a substantially vertically flat anterior surface 2A, a substantially vertically flat posterior surface 2B and a chewing surface 2C extending therebetween, also as shown in
In another example that is directed now to the lower rearward teeth, rearward tooth 31 includes a substantially vertically flat anterior surface 31A, a substantially vertically flat posterior surface 31B and a chewing surface 31C extending therebetween, also as shown in
DCA 200 includes multiple brushes 211, 212 and 213 situated about brush portion 202. Brushes 211, 212 and 213 may alternatively be referred to as bristle arrays. In the embodiment of
The statements above with respect to a particular brush geometry being used to brush a corresponding tooth surface type of upper teeth 1-16 apply as well to lower teeth 17-32 in a one-to-one relationship. For example, convex brush 211 may be used to brush the posterior concave surfaces of not only upper teeth 6-11, but also to brush the posterior concave surfaces of lower teeth 22-27. Likewise, concave brush 212 may be used to brush the anterior convex surfaces of not only upper teeth 6-11, but also the corresponding anterior convex surfaces of lower teeth 22-27. Moreover, flat brush 213 may be used not only to brush the chewing surfaces, flat anterior surfaces and flat posterior surfaces of rearward teeth 1-5 and 12-16 of the upper mouth, but also to brush the corresponding chewing surfaces, flat anterior surfaces and flat posterior surfaces of rearward teeth 17-21 and 28-32 of the lower mouth. In other words, the same principles disclosed above with respect to the upper teeth apply as well to the lower teeth. It is noted that teeth 5 and 12 are considered as being transitional teeth and can be brushed with either a convex or flat surface.
In another embodiment, the DCA may include 2 brushes such as convex brush 211 and concave brush 212 equiangularly spaced about brush portion 202 at approximately 0° and approximately 180°. In yet another embodiment, the DCA may include 2 brushes such as convex brush 211 and flat brush 213 equiangularly spaced about brush portion 202 at approximately 0° and approximately 180°. In still another embodiment, the DCA may include 2 brushes such as concave brush 212 and flat brush 213 equiangularly spaced about brush portion 202 at approximately 0° and approximately 180°. In these last 3 embodiments wherein the DCA includes 2 different geometry brushes, respective matching tactile feel regions may be aligned with the corresponding 2 brushes to denote the geometry (convex, concave or flat) of the respective brushes.
To use DCA 200, the user inserts DCA 200 into the mouth and brushes a particular geometry tooth surface with a corresponding mating geometry brush array. For example, to brush the posterior concave surfaces of front teeth 6-11, the user inserts DCA 200 into the mouth while orienting the convex brush 211 to brush these posterior concave tooth surfaces. In
When the user is done brushing with concave brush 212 and wishes to commence brushing with flat brush 213, without removing the brush from the mouth, the user rotates DCA 200 until the user feels flat tactile feel region 223. When the user's thumb or other member senses flat tactile feel region 223, the user immediately knows the orientation of flat brush 213. The user then proceeds with brushing by using flat brush 213 to brush the flat tooth surfaces or other appropriate tooth surfaces.
For ease of understanding and illustration, some of the features of DCA 200 have been emphasized and not drawn to scale. In actual practice, the brushes 211, 212 and 213 may exhibit a much lower profile than illustrated to allow for easier movement in the mammalian mouth. Using a smaller profile for brushes 211, 212 and 213 is helpful when DCA 200 is used on smaller mammals such as humans. Likewise, tactile feel regions 221, 222 and 223 may exhibit a much lower profile than illustrated for the same reason.
While
As noted,
While DCA 200 is shown in
In another embodiment, convex brush 211, concave brush 212 and flat brush 213 exhibit different respective colors. In this particular embodiment, convex tactile feel region 221 exhibits the same color as convex brush 211 to which it corresponds. Likewise, concave tactile feel region 222 exhibits the same color as concave brush 212 to which it corresponds. Further, flat tactile feel region 223 exhibits the same color as flat brush 213 to which it corresponds. This color arrangement may assist the user in the orientation and operation of DCA 200.
