Fold edge type dental floss blade

Abstract

The invention relates to the technical field of oral medicine, in particular to a fold edge type dental floss blade, which comprises a guide master slice, a bolt, a cutting edge notch, a handle, a blade, a blade hole, a guide sub slice, a bolt hole and a guide groove. The external outline of the guide master slice is elliptic, the linear guide groove is arranged on the edge of the guide master slice, the edge of the guide groove and the external edge of the guide master slice are in arc transition, the external outline of the guide sub slice and the external outline of the upper half of the guide master slice are mutual mirroring shapes, the guide groove and the major axis of the ellipse of the guide master slice form an included angle of 45 degrees, and the inner end of the guide groove is provided with the cutting edge notch which is right angular and fold line shaped. The fold edge type dental floss blade avoids the larger damage vertical drawing force which is generated when a traditional dental floss pick is pulled out, and accordingly, the damage to the joint of the tooth root and the alveolar bone is avoided.

Description

technical field [0001] The invention relates to the technical field of stomatology, in particular to a turning blade type dental floss cutter. Background technique [0002] Existing dental floss sticks usually consist of a bow frame and a stretched polyester fiber dental floss. When in use, the dental floss is pressed into the interdental space (see the figure in the accompanying drawing). Figure 6 ), and then move back and forth between the teeth to take out the tartar, and then pull out the floss from the teeth. It is generally accepted by those skilled in the art that using a dental floss stick to remove tartar is a healthy operation method, and because the dental floss is soft, it will not cause damage to the teeth. But this view is wrong for the following reasons: [0003] 1. The shape of the crown usually has the characteristics of being large at the top and small at the bottom, which makes the gap between two adjacent teeth have the characteristics of small at the t...

[0004] 2. The chewing function of the teeth determines that the teeth have a strong ability to withstand vertical pressure, but the large and small structure of the root makes the tooth's ability to withstand tension relatively weak

Long-term use of existing dental floss sticks and repeated pulls on the teeth will greatly reduce the bonding force between the root and the alveolar bone, resulting in loosening of the tooth root. Therefore, many patients feel that the more the teeth are picked, the looser the teeth
