Crown repair adjacent gap dynamometer for stomatology department

Abstract

The invention discloses a crown repair adjacent gap dynamometer for a stomatology department. The crown repair adjacent gap dynamometer comprises a bottom plate, a lifting unit, a rotating unit and acontroller. The controller is arranged in the middle of the front side surface of the bottom plate. The lifting unit comprises a motor, a fixed block, a lead screw, a movable block and a mounting plate. The bottom end of the fixed block is connected with the middle part of the upper surface of the bottom plate. A groove is formed in the front side of the fixed block. A lead screw is rotationally connected with the inside groove. The bottom end of the motor is connected with the top end of a fixed block. An output shaft of the motor is connected with the top end of the lead screw. The movable block is slidably connected with the groove in the front side of the fixed block. A screw hole in the side of the movable block is in threaded connection with the lead screw. The front side of the movable block is connected with the middle of the rear side of the mounting plate. A rotating unit is arranged on the front side of the mounting plate. A fixed unit is arranged on the top end of the mounting plate. The crown repair adjacent gap dynamometer for the stomatology department has the advantages of simple structure, convenient use and accurate measurement.

Description

technical field [0001] The invention relates to the technical field of oral cavity measuring equipment, in particular to a force measuring instrument for the adjacent gap for dental crown restoration. Background technique [0002] Dental surgeons generally use dental floss when installing fixed crowns on patients, and feel the closeness of contact between the restoration and the restoration, or between the restoration and the adjacent teeth, to judge whether the new crown is related to the new crown, or whether the new crown is related to the adjacent teeth. Whether the adjoining gap between them is tight. When the doctor thinks that the adjoining relationship is normal, he will use adhesive to permanently bond the crown to the abutment tooth. A loose adjoining relationship may cause easy gaps between the crown and the adjacent teeth. Impacted food will affect the patient's use, and the tight adjacent relationship will cause the patient's discomfort. Since the existing techn...

Problems solved by technology

[0002] Dental surgeons generally use dental floss when installing fixed crowns on patients, and feel the closeness of contact between the restoration and the restoration, or between the restoration and the adjacent teeth, to judge whether the new crown is related to the new crown, or whether the new crown is related to the adjacent teeth. Whether the adjoining gap between them is tight. When the doctor thinks that the adjoining relationship is normal, he will use adhesive to permanently bond the crown to the abutment tooth. A loose adjoining relationship may cause easy gaps between the crown and the adjacent teeth. Impacted food will affect the patient's use, and the tight adjacency will cause the patient to feel uncomfortable. Since the existing technology relies entirely on the doctor's touch, it is impossible to objectively obtain a value to judge whether the adjoining gap is appropriate
