Description

Technical Field

[0001] The utility model belongs to the technical field of all-ceramic dentures, and in particular relates to an all-ceramic denture with good friction resistance. Background Art

[0002] Dentures are a general medical term for restorations made after partial or complete tooth loss in the upper and lower jaws. Dentures are divided into two types: removable and fixed. Fixed dentures (commonly known as "fixed dentures") cannot be removed and worn by the patient themselves. Currently, single fixed dentures are made. Although they are customized according to the needs of tooth implantation to ensure that the dentures can fit the teeth on both sides well, the postoperative wrapping of the denture by the gums generally needs to be slowly restored. During the recovery period, the gap between the denture and the roots of adjacent teeth is poorly sealed by the gums, which will cause food debris to easily enter when eating. The corruption and growth of food debris will greatly inhibit the recovery time of the gums and easily contaminate and decay adjacent healthy teeth. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide an all-ceramic denture with good friction resistance, which solves the problem that the current single fixed denture is customized according to the needs of tooth implantation to ensure that the denture can fit the teeth on both sides well, but the postoperative wrapping of the denture by the gums generally needs to be slowly restored. During the recovery period, the gap between the denture and the roots of adjacent teeth is not well sealed due to the poor gum sealing, which will cause food residues to easily enter when eating. The corruption and breeding of food residues will greatly inhibit the recovery time of the gums and easily contaminate and decay the adjacent healthy teeth.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: an all-ceramic denture with good friction resistance, including a denture, a mounting groove is opened on the lower side of the denture, a plug-in column is inserted into the inner side of the mounting groove, a threaded column is arranged at the lower center of the plug-in column, movable grooves are opened on both sides of the denture, a filling block is slidably arranged on the inner side of the movable groove, and a spring sheet is arranged between the filling block and the inner side wall of the movable groove.

[0005] The beneficial effects of the utility model are as follows: when the denture is inserted, the filling block is squeezed by the adjacent teeth, which will squeeze the spring sheet one inward, and at the same time, the spring sheet one will reversely squeeze the filling block, so that the filling block is close to the side walls of the adjacent teeth, and the filling block is close to the side surfaces of the adjacent teeth. When customizing the denture, the side surfaces of the filling block can be made according to the contact surfaces of the adjacent teeth so that they can fit together with the contact surfaces of the adjacent teeth. In this way, when the denture is installed, the filling block will close the gap between the denture and the adjacent teeth, thereby preventing food residues from entering, preventing the corruption and growth of food residues that inhibit the recovery time of the gums, and preventing them from contaminating and corroding the adjacent healthy teeth.

[0011] The beneficial effects of this improvement are: the insertion groove is provided for insertion into the positioning column, which facilitates the connection and positioning of the denture top and the denture seat, and increases the fit and stability of the connection between the denture seat and the denture top.

[0012] In order to increase the sealing of the connection between the denture seat and the denture top;

[0013] As a further improvement of the above technical solution: a sealing groove is provided on the upper side of the denture seat, and a separator ring is provided on the lower side of the denture top corresponding to the sealing groove, and the separator ring is fitted and plugged into the sealing groove.

[0014] The beneficial effect of this improvement is that the sealing groove and the separation ring are arranged to fit together, so as to increase the sealing property of the connection between the denture seat and the denture top, and prevent food residues and saliva from entering and being retained, thereby causing corruption and breeding of bacteria.

[0015] For better strength and friction resistance;

[0016] As a further improvement of the above technical solution: the denture seat and the denture top are both made of ceramic material, and the outer sides of the denture seat and the denture top are provided with a smooth porcelain layer.
