Description

Technical Field

[0001] The utility model belongs to the technical field of all-ceramic dentures, and particularly relates to an all-ceramic denture with a reduced probability of ceramic chipping. Background Art

[0002] All-ceramic dentures are porcelain restorations that cover the entire crown surface and do not contain metal inner crowns. Since the inner crowns are no longer made of metal, but are made of high-strength porcelain materials that are close to the color of teeth, they are more beautiful than metal-based porcelain restorations and have been widely used in clinical practice, especially in the aesthetic restoration of anterior teeth. All-ceramic dentures are also a type of denture that can be installed later. The appropriate all-ceramic denture is selected for installation based on the different tooth vacancies of the patient. The stability of the all-ceramic denture after installation determines its comfort in later use and its corresponding service life. If the all-ceramic denture is loose after installation, it will not be able to effectively crush the food during the chewing process, making eating inconvenient. The looseness will also cause a certain psychological pressure on the user, making it impossible to give full play to the effectiveness of the all-ceramic denture.

[0003] Secondly, if the all-ceramic denture is loose, it may aggravate the wear on the surrounding teeth. The surrounding teeth may not be dentures themselves, which will cause wear on the user's own teeth. The wear of the all-ceramic denture itself will also reduce its service life.

[0004] In summary, the insufficient stability of all-ceramic dentures will affect their subsequent use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
