The subject disclosure relates to brushing, scrubbing, and general cleaning, and more particularly, to implements which concurrently brush plural tooth surfaces.
The field of teeth cleaning includes a number of approaches to brushing teeth. In the very basic, conventional approach is to provide a manually operated single brush head which the user applies to a single tooth or two overlapping teeth at a time until the user moves on.
Other approaches use electric powered toothbrushes in response to the ineffective approach of manual toothbrushes. Some electric toothbrushes power a single head in either a rotary motion (where the brush head spins) or in a reciprocating motion. Still, the single brush head approach requires time to apply the brush to each tooth.
Some devices have proposed multiple toothbrush heads but are limited in their effectiveness because of choice in the range of motion which for some is, for example, along an axis into and out of the user’s mouth. As may be seen, this may be ineffective because the direction of brushing does not follow the front face of the front teeth, which are the teeth most visible to others. Still yet, the rear surface of the front teeth may likewise be generally missed by such an approach.
In some instances, conventional brushing devices lack enough bristles to adequately reach each tooth surface simultaneously.
As can be seen, there is a need for a device that improves the coverage of teeth and thereby reduces the amount of time it takes.
In one aspect of the disclosure, a teeth cleaning system is disclosed. The system comprises: an arcuate tray configured to receive a set of teeth, wherein the tray includes: an inner arcuate wall, an outer arcuate wall, a baffle positioned transversely across between an inner surface of the outer arcuate wall and an inner surface of the inner arcuate wall and defining an upper channel for receiving teeth of an upper jaw and defining a lower channel for receiving teeth of a lower jaw, and a plurality of bristles positioned in the upper channel and in the lower channel; a handle; a connector, wherein the arcuate tray is coupled to the handle by the connector; a motor coupled to the handle; and an oscillator coupled to the connector, wherein the oscillator is configured to move the arcuate tray side-to-side along the same plane as the baffle in response to operation of the motor.

It is understood that other configurations of the subject technology will become readily apparent to those skilled in the art from the following detailed description, wherein various configurations of the subject technology are shown and described by way of illustration. As will be realized, the subject technology is capable of other and different configurations and its several details are capable of modification in various other respects, all without departing from the scope of the subject technology. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive..
The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The appended drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be apparent to those skilled in the art that the subject technology may be practiced without these specific details. Like or similar components are labeled with identical element numbers for ease of understanding.
In general, exemplary embodiments of the subject technology provide a cleaning system for teeth that provides improved coverage area and an improved range of motion to more effectively brush teeth with motorized actuation. It will be appreciated that, aspects of the system include an arrangement of bristles that provide greater bristle density than in previous systems. The greater density covers more tooth surfaces to be brushed. The system includes a motor to automatically actuate the brushing features. The system may automatically brush all tooth surfaces during operation. Another aspect contributing to the improved brushing performance includes the motion of actuation used in some embodiments. The system may be configured to actuate the brushing in a side-to-side range of movement, which may be more natural to users.

In some embodiments, the outer arcuate wall 115, the inner arcuate wall 145, and the top and bottom surfaces of the baffle 135 include a plurality of receptacles (holes) (
In an exemplary embodiment, the bristles may be arranged in a density of approximately 42 bristles per hole and 452.4 bristle-hairs per square centimeter. Embodiments may vary the bristle density between 324 bristles per cm2 - 646 bristles per cm2. As will be understood, the density of bristles may vary depending on factors such as bristles per hole, number of holes, spacing of holes, diameter of holes, and diameter of bristle strands used. For example, in embodiments that use softer bristles with thinner strand diameters than the embodiment with 42 bristles per hole, there may be approximately 84 bristles per hole which yields approximately the same density but with a softer brush rating. Similarly, embodiments using firmer bristles with thicker strand diameters may use 24 bristles per hole to achieve the same density. Accordingly, the bristle density may be manipulated by increasing or decreasing the strand diameter and/or the number of strands per hole. In addition, the other aforementioned factors (relating to hole position, size, and spacing) may be manipulated to generate a bristle density within the disclosed range. For example, more empty areas between holes may require more bristles to provide the same density and vice versa.
Thus, when referring to “bristle density”, the subject disclosure encompasses in general the density of bristle material per area with the understanding that substitutions may be made in any of the underlying factors of bristle density while still falling within the scope of the technology herein. The bristle material per area may be based on the diameter of a bristle used in an embodiment multiplied by the numbers of bristles per unit of area.
Embodiments may include 327 to 653 holes overall on the surfaces 120 and 125, and on both sides of the baffle 135. In an exemplary embodiment, there may be approximately 480 holes overall on the surfaces 120 and 125, and on both sides of the baffle 135. Embodiments may position holes with a distance of 1.8 mm to about 0.75 mm between holes. In some embodiments, there may be approximately 7.72 holes per cm2 of a surface (120, 125, 135) to approximately 15.38 holes per cm2. In an exemplary embodiment, there are approximately 11.31 holes per cm2.
There may be approximately 42 bent bristles/hole. Embodiments may include a range of approximately 25-55 bristles per hole. The bristle thickness may range from 0.01 mm to 0.2 mm. For embodiments with 42 bristles per hole, the bristle thickness may be approximately 0.15 mm. In total, there may be approximately 13,100 to 26,120 bent bristle hairs inserted into the tray assembly 110. In an exemplary embodiment, there may be 19,200 bent bristle hairs inserted into the tray assembly 110. As will be seen, the density of bristles is above the conventional density of bristles in previous systems, which leads to improved coverage of the brushing area for the surfaces of teeth. With a minimal range of motion, the system 100 is able to brush teeth more efficiently. It will be appreciated that this is a significant improvement in technology since the range of space available to move laterally within a user’s mouth is limited. The density of bristles 130 in the subject technology allows for better brushing effectiveness in the limited range of lateral movement.
In some embodiments, the inner surface 120 of the outer arcuate wall 115 and/or the inner surface 125 of the inner arcuate wall 145 may include slots. See

This camera 320, flash 318, and hardware/software may provide simple scan or dual scan capabilities according to certain embodiments. A machine learning component may exist on the PCB 322 to enable automatic capturing of simple scans for routine oral and dental photography. These images may be processed internally by the teeth cleaning system 300 or may be transmitted to a remote server for analysis by external software and/or dental professionals. A transmitter or transceiver may be used to transmit said data to an external network. A deep scan option may also be available for more in-depth dental imaging. This imaging and processing may enable the detection of dental plaque, tooth decay, gingivitis, periodontitis, gum recession, tooth surface shade, and demineralization. In some embodiments, in-depth dental imaging may also detect misplacement of the teeth, oral cancer, and other health-related symptoms, including exhaustion, depression, pulse, blood pressure, etc. It can be difficult for a user to keep track of his or her dental health and detect inconsistencies when they arise, especially if the user does not or cannot visit a dental professional regularly. These features can offer effortless oral health monitoring on a consistent basis, allowing users to detect any symptoms in the early stages before they evolve into serious health issues. The teeth cleaning device may also include a lift to wake sensor (not shown) that enables the features of the handle assembly 200 after the user lifts the device. This sensor may be controlled by the hardware, firmware, and software on the PCB.
In some embodiments, the hardware and software of the teeth cleaning system 300 uses machine learning technology to automatically detect a person’s face and teeth to make the process of capturing the necessary images less time consuming and cumbersome. An initial scan of the user’s teeth, gums, mouth, and face may be necessary to set a baseline for this type of machine learning technology. Data storage may be required to store said images and deep scans of said images. Directions or instructions for taking the scans, images, or videos of the user’s teeth and gums may be given by the teeth cleaning device 300 through a speaker (not shown) or by instructions on the display screen 316. The directions may also be given through an app on a user’s mobile device that communicates with the teeth cleaning system 300 through a network. These directions may include commands concerning placement, movement, or handling of the teeth cleaning system 300 while the images or scans are being taken. More specifically, the directions for the scanning may be sent from an external server or cloud network and may be triggered by the user’s input in the app on the user’s mobile device. In some embodiments, complex instructions may be required to ensure that the teeth cleaning system 300 can detect the user’s face, smile, and teeth. The images or scans taken by the teeth cleaning system 300 may be updated or annotated by the user, software, or dental professional in certain embodiments. Segmentation and/or cropping out may also be necessary to process and analyze the user’s teeth and gums. A user’s interaction with the app on a mobile phone may enable additional features of the teeth cleaning system, including tracking of dental activities, dental appointments, videos of dental care, dental care tips, etc.
The flash 318 may be covered with a type of Fresnel lens to light up the teeth as well as autofocus technology that improves the quality of the images or scans taken of the user’s teeth and gums. The camera 320 may be a 5-mega pixel camera that offers colored images or could also be an IR camera (LiDAR). The hardware and software (at least partially on the PCB 322) ensures that the data from the corresponding images or scans may be acquired, processed, and sent to the external server or cloud network according to a secure protocol to protect the user’s health data. As discussed above, these images and scans may be part of a broader oral care system where teledentistry is available. The high-resolution images and scans may be accessed and analyzed by a dental professional, which may enable remote diagnostics and treatment. Additionally, the dental professional may utilize the benefit of machine learning technology for assistance in dental treatment as the catalog of dental images may provide a better overall view of the user’s dental health. Teledentistry may also be accomplished through the corresponding app on a mobile phone.
