Description

Technical Field

[0001] The utility model belongs to the technical field and relates to a removable denture that reduces damage caused by hard food. Background Art

[0002] Removable dentures, also known as removable dentures, are a type of prosthesis that can be removed and put on by the patient. They use the remaining natural teeth, mucosa and bone tissue under the base as support, and are retained by the denture retainer and base. They are designed to restore the shape and function of missing teeth, as well as the shape of the defective alveolar ridge, jawbone and surrounding soft tissue. When removable dentures cannot effectively relieve chewing pressure during use, the following problems may occur:

[0003] Chewing pressure that cannot be effectively buffered may cause excessive pressure on the mucosa and bone tissue under the base. In the long run, this may cause mucosal ulcers and pain, and even induce absorption and remodeling of bone tissue, further affecting the retention and stability of the denture. Removable dentures cannot relieve pressure during chewing, and may also have an adverse effect on adjacent natural teeth. Excessive pressure may cause damage to the periodontal tissue of natural teeth, induce periodontal disease, and may even cause natural teeth to loosen or fall off. Therefore, there is an urgent need for a removable denture that can reduce damage from hard food to solve the above problems. Utility Model Content
