Description

Technical Field

[0001] The present application relates to the technical field of polishing abrasive tools, and in particular to a handheld denture polishing device. Background Art

[0002] Denture polishing is a common dental technique used to improve the appearance and texture of dentures, making them more comfortable, natural and durable. The polishing process uses special tools and abrasives to remove rough, uneven or excess material from the denture surface to achieve a smooth and bright effect. Denture polishing is an important process that can improve the appearance, comfort and service life of dentures, and improve the oral health and quality of life of patients. Sandpaper polishing is a method of mechanical polishing. At present, in clinical applications, sandpaper can only be held in the hand for grinding and polishing. This polishing method is inefficient and difficult to operate. It is difficult to achieve the polishing requirements required for removable dentures for polishing detailed parts.

[0003] In the related art, a Chinese patent document with authorization announcement number CN213828388U discloses a handheld denture polishing device, including a dental handpiece and a polishing component, the polishing component including a connecting rod, a buffer transition end and denture polishing sandpaper, the denture polishing sandpaper is adhered to the side wall of the buffer transition end through the adhesive on the back of the sandpaper base paper, and the buffer transition end is driven to rotate by a driving member in the dental handpiece, so that the denture polishing sandpaper polishes the denture.

[0004] However, in the above scheme, the denture polishing sandpaper is fixed to the side wall of the buffer transition end by means of adhesive. When the denture polishing sandpaper needs to be replaced, the sandpaper and the side wall are stuck together, making it extremely difficult for the operator to remove the sandpaper from the buffer transition end, which is not conducive to the reuse of the buffer transition end.
