Embodiment 1

[0061] This embodiment provides a dental card, such as Figure 1-Figure 9 As shown, a transparent card body 3 is included, and the card body 3 is provided with a card application value 2 and a plurality of measurement scale areas 1 .

[0062] Such as figure 1 As shown, it is the structural diagram of the 7.5 dental card, such as figure 2 As shown, it is the structural diagram of 8.5 dental card, such as image 3 As shown, it is a structural diagram of a 9.5 dental card. This embodiment includes but is not limited to the above three dental cards with applied values. The card body of each dental card is provided with applied values ​​(such as 7.5, 8.5, 9.5). When it is convenient to use, select a suitable dental card according to the application value, and place the transparent dental card in front of the tooth model 4 for comparative measurement. Due to the different tooth sizes of each person, different dental cards are selected. The 7.5 dental card is suitable for users w...

Embodiment 2

[0097] This embodiment provides a method for measuring the size of a dental model based on a dental card comparison, using the dental card described in Embodiment 1, such as Figure 10 As shown, including but not limited to two steps S1 and S2:

[0098] S1, align the measurement scale area on the selected tooth card with the tooth model 4 . Step S1 is specifically:

[0099] Use the middle transverse scale line 112 of the central incisor scale group 11 as the transverse reference line, and align it with the neckline of the central incisor 41 of the tooth model 4;

[0100] Take the common vertical scale line 111 of the two central incisor scale groups 11 as the vertical reference line, and align with the interdental line between the two central incisors 41 in the tooth model 4 .

[0101] A suitable measurement scale area needs to be selected before alignment. First, the dental cards of each model (placed before the tooth model 4) are compared with the tooth model 4, and the a...

Abstract

The invention belongs to the technical field of dentistry and specifically relates to a dental card and a method for measuring dental model sizes based on dental card comparison. The dental card comprises a card main body, wherein a plurality of measurement scale areas are arranged on the card main body; each measurement scale area comprises a plurality of adjacent and abreast measurement scale sets which are used for measuring tooth sizes; each measurement scale set comprises two parallel vertical scale lines with the equal height, a middle horizontal scale line and a lower horizontal scale line, the middle horizontal scale line and the lower horizontal scale line perpendicularly intersect with the vertical scale lines, the middle horizontal scale line is arranged in the middles of the vertical scale lines, the lower horizontal scale line is arranged at the lower parts of the vertical scale lines, and an inclined scale line is arranged between the two vertical scale lines. The dentalcard disclosed by the invention has the advantages of a simple structure, low cost and convenience in use; the tooth sizes can be obtained through reference comparison between the scale lines on the dental card and the tooth models, the tooth sizes can provide reference standards for manufacturing false tooth, and false tooth manufacturing accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of dentistry, and in particular relates to a dental card and a method for comparing and measuring the size of a dental mold based on the dental card. Background technique [0002] Dentures are dentures that are inlaid to restore functions such as chewing, aesthetics, and pronunciation after tooth loss or extraction. Denture repairs are divided into removable dentures and fixed dentures, and fixed dentures are further divided into implant dentures, post-crown dentures, and crown-sleeved bridges. Different users have different tooth sizes, so when producing dentures, it is necessary to carry out production and processing according to the tooth size of the user's teeth. [0003] In the existing denture production, the size of the denture mainly depends on the skill level of the technicians, and the skill level of the technicians is uneven, which in turn affects the accuracy of the denture production. The exis...
