This is a dental measuring tool used to check the degree of tooth grinding when grinding and capping teeth. As shown in the "Reference Front View," this tool consists of a gripping portion, an interocclusal measurement portion, and a grinding shoulder measurement portion. For example, when grinding and capping a lower jaw tooth, as shown in "Reference Figure 1 Showing the State of Use," the tip of the interocclusal measurement portion is inserted between the ground lower jaw tooth and the upper jaw tooth to measure the gap. Furthermore, as shown in "Reference Figure 2 Showing the State of Use," the grinding shoulder measurement portion is placed along the ground lower jaw tooth, and the shoulder (foot-like portion) of the lower jaw tooth is measured using the tip diameter of the grinding shoulder measurement portion, and the height of the lower jaw tooth is measured using the scale on the grinding shoulder measurement portion.

The utility model relates to the field of jaw crushers, and particularly discloses a jaw crusher and a jaw plate thereof, the jaw crusher comprises a fixed jaw plate and a movable jaw plate, the fixed jaw plate and the movable jaw plate respectively comprise a plate body, a positioning piece and a plurality of jaw teeth, the plurality of jaw teeth are parallel to each other and are distributed at equal intervals along the width direction of the plate body, and the jaw teeth are detachably connected to the plate body. The positioning piece is connected to the upper end of the plate body through a bolt and abuts against the upper end of the jaw tooth, so that the jaw tooth is limited on the plate body. The jaw teeth are detachably connected with the plate body, and when the jaw teeth in the middle of the plate body are seriously abraded, the jaw teeth in the middle can be independently detached and replaced, so that the operation difficulty of jaw tooth replacement is reduced, meanwhile, the utilization rate of other jaw teeth with small abrasion is increased, and the stability of the jaw teeth in the crushing process is ensured through the arrangement of the positioning piece.

The invention relates to the technical field of oral endothelial valve repair, and particularly discloses an oral endothelial valve repair postoperative occlusion limiting device which comprises an upper tooth socket and a lower tooth socket which are matched with healthy side upper jaw teeth and healthy side lower jaw teeth respectively, and the end of the upper tooth socket is connected with the end of the lower tooth socket through a curved surface connecting piece. The surface, facing the lower tooth socket, of the upper tooth socket is of a bionic structure of maxillary teeth; the lower tooth socket comprises a lower base, an upper tooth seat and a plurality of adjusting blocks, the lower surface of the lower base is matched with mandibular teeth, the upper tooth seat is arranged on the uppermost adjusting block, and the upper surface of the upper tooth seat is of a bionic structure of the mandibular teeth; flanges are arranged on the two sides of the upper tooth base, a groove body is formed between the two flanges, limiting protrusions are arranged on the surfaces, located in the groove body, of the flanges, clamping grooves matched with the limiting protrusions are formed in the inner side surface and the outer side surface of each adjusting block, and the limiting protrusions are clamped into the clamping grooves to lock the upper tooth base and the adjusting blocks. And according to the swelling condition of an operation area, the healthy side can be precisely limited, and the occlusion height can be dynamically adapted.

The invention discloses a sectional type appliance for quickly correcting posterior tooth locking by stress dispersion connection, which comprises a sectional type tooth socket body, the sectional type tooth socket body is a shell-shaped cavity for wrapping the tongue side and the cheek side of a complete dentition, the sectional type tooth socket body comprises a tooth socket body for covering other dentitions and a tooth socket body for covering posterior tooth locking / reverse locking, and the shell-shaped cavity is a shell-shaped cavity for covering the tongue side and the cheek side of the complete dentition.
