The present disclosure will be described hereinafter in conjunction with the drawings and embodiments. The following embodiments are for illustrative purposes only, but shall not be used to limit the scope of the present disclosure.
An object of the present disclosure is to provide a tooth processing device and a tooth processing method, so as to remove a decayed tooth portion of a user accurately.
The present disclosure provides in some embodiments a tooth processing device which, as shown in
According to the tooth processing device in the embodiments of the present disclosure, in the case that it is necessary to remove the decayed tooth portion, the tooth image of the user is collected by the image collection circuit on the dental model 1 worn by the user, then the collected tooth image is analyzed to determine the decayed tooth portion, and then the dental drill 3 is moved to the decayed tooth portion, so as to remove the decayed tooth portion through grinding. As a result, it is able to remove the decayed tooth portion accurately through image analysis, independent of skills of a dentist.
The dental model 1 is of a hollowed-out housing having a shape approximately identical to teeth of the user. In the case that tooth problems occur and the dental model 1 is worn by the user, the tooth image may be taken by the image collection circuit on the dental model 1. To be specific, the dental model 1 includes an upper portion and a lower portion. In the case that the dental model 1 is worn by the user, the upper portion of the dental model 1 corresponds to upper teeth of the user, while the lower portion corresponds to lower teeth of the user. The image collection circuit may be arranged at a side of the upper portion to collect an image of the lower teeth, and arranged a side of the lower portion to collect an image of the upper teeth.
The decayed tooth portion is black while a normal tooth portion is white or light yellow, so it is able to determine the decayed tooth portion through color comparison. To be specific, the processing circuit 2 includes a color comparison sub-circuit (not shown) configured to compare a color of the tooth in the tooth image with a predetermined standard color, and determine a tooth portion whose color is different from the predetermined standard color as the decayed tooth portion. Then, the dental drill 3 may be moved to the decayed tooth portion under the control of the processing circuit 2, so as to remove the decayed tooth portion through grinding.
The dental drill 3 is capable of moving freely on the dental model 1. To be specific, as shown in
In addition, as shown in
After the removal of the decayed tooth portion through grinding, the clean liquid may be injected into the user's mouth, so as to clean the user's mouth. To be specific, the clean liquid may be water.
In addition, the tooth processing device may further include an ultrasonic wave generation circuit (not shown) arranged on the dental model 1. The processing circuit 2 is further configured to, after the clean liquid has been injected into the user's mouth via the liquid supply port 5, control the ultrasonic wave generation circuit to generate an ultrasonic wave so as to vibrate the clean liquid. Through the ultrasonic wave, it is able to clean a surface of the tooth and a slit between the teeth in a better manner.
In addition, as shown in
Here, as shown in
In addition, after the removal of the decayed tooth portion, it is also necessary to fill up the tooth missing portion. Prior to filling up the tooth missing portion, it is necessary to determine an amount of a dental filling material to be used.
In a possible embodiment of the present disclosure, the tooth processing device further includes an infrared scanning circuit (not shown). After the injection of the clean liquid into the user's mouth via the liquid supply port 5, the infrared scanning circuit is configured to scan the user's mouth, and determine a position and a shape of the tooth missing portion in accordance with a boundary between the clean liquid and the tooth in an infrared scanning image acquired by the infrared scanning circuit, so as to determine the amount of the dental filling material to be used.
In another possible embodiment of the present disclosure, the dental model 1 is made of a deformable material, which may be selected in accordance with the practical need. The processing circuit 2 is further configured to, after the tooth occlusion, determine the position and the shape of the tooth missing portion in accordance with a deformation amount of the dental model 1, so as to determine the amount of the dental filling material to be used.
In addition, as shown in
After the determination of the amount of the dental filling material to be used, the dental filling material may be injected to the ground tooth portion via the dental drill 3. The dental drill 3 is provided with a receiver for receiving therein the dental filling material. The processing circuit 2 is further configured to, after the decayed tooth portion has been completely removed, inject the dental filling material to the ground tooth portion via the dental drill 3, so as to fill up the tooth missing portion. In this way, it is able to fill up the tooth missing portion through the dental drill 3, rather than using any additional device. The dental filling material may be injected into the receiver in the dental drill 3 via the liquid supply port 5, and injected to the tooth missing portion via a hole in the dental drill 3. Due to its ultra-thin structure, it is able for the dental drill 3 to fill up the tooth missing portion to the maximum extent. As a result, it is able to prevent the occurrence of any other tooth problems due to the incomplete dental filling operation, and meanwhile facilitate the removal of impurities as compared with the related art where an oversize slit occurs in the case that the dental filling operation is performed manually.
In addition, as shown in
The present disclosure further provides in some embodiments a tooth processing method for use in the above-mentioned tooth processing device, which includes steps of: after the dental model 1 is worn by the user, collecting, by the image collection circuit, the tooth image; and analyzing, by the processing circuit 2, the collected tooth image so as to determine the decayed tooth portion, and controlling the dental drill 3 to move to the decayed tooth portion so as to remove the decayed tooth portion through grinding.
According to the tooth processing method in the embodiments of the present disclosure, in the case that it is necessary to remove the decayed tooth portion, the tooth image of the user is collected by the image collection circuit on the dental model 1 worn by the user, then the collected tooth image is analyzed to determine the decayed tooth portion, and then the dental drill 3 is moved to the decayed tooth portion, so as to remove the decayed tooth portion through grinding.
