Description

Technical Field

[0001] The utility model belongs to the technical field of movable dentures and relates to a customized denture capable of protecting gums. Background Art

[0002] Removable dentures, also known as removable dentures, are restorations that can be removed and worn by the patient. They include removable partial dentures and full dentures. Removable dentures use the remaining natural teeth, the mucosa under the base and the bone tissue as support, and rely on the denture retainers and bases for retention. This type of denture uses artificial teeth to restore the shape and function of missing teeth, and uses base materials to restore the shape of the defective alveolar ridge, jawbone and surrounding soft tissues. As a removable denture, it has brought good news to many patients with missing teeth. However, if the connection is not tight, it may cause a series of problems to the gums.

[0003] If the connection of the removable denture is not stable, it may cause it to frequently loosen and shift during use. In this case, the friction between the denture and the gums will intensify. In the long run, the gums may be worn, causing symptoms such as redness, swelling, and pain. More seriously, long-term friction may also cause gum atrophy and gradually expose the alveolar bone, which not only affects the health of the oral cavity, but may also affect the retention effect of the denture. Therefore, there is an urgent need for a customized denture that can protect the gums to solve the above problems. Utility Model Content
