A spliced ​​metal denture and manufacturing method thereof

Abstract

The invention discloses a spliced ​​metal denture and a manufacturing method thereof, belonging to the technical field of metal dentures, comprising tooth enamel surface layer, hard layer, wrapped soft layer and tooth edge, the middle part of the hard layer protrudes upwards , forming a raised block, the upper surface of the raised block is provided with a layer of tooth enamel surface layer, the lower end of the wrapped soft layer is close to the gums, and the wrapped soft layer is consistent with the upper surface of the gums, the raised The connection between the block and the side forms an oblique downward tooth groove, the upper end of the wrapped soft layer is located in the tooth groove on both sides of the hard layer, and the inner surface of the wrapped soft layer is in contact with the hard layer. Layers are connected to each other. Metal alloy is used as the framework of the denture, and the load-bearing performance of the denture is significantly improved; the wrapped soft layer is closely connected with the inner wall of the oral cavity, the denture is not easy to loose, and the local performance of the denture is optimized.

Description

technical field [0001] The invention relates to the technical field of metal dentures, in particular to a spliced ​​metal denture and a manufacturing method thereof. Background technique [0002] Oral problems caused by defects and deformities of teeth and dentition affect people's chewing, pronunciation and aesthetics, and can also easily cause periodontal tissue lesions and loosening and deformation of adjacent teeth. These oral problems can be effectively addressed with denture restorations. Due to the special environment of the oral cavity and the special purpose of the teeth, denture materials need to meet the requirements of physical and chemical stability, service life, mechanical properties, biocompatibility and aesthetics. Buckle on the teeth of the oral cavity, remove the medium after solidification, and form a denture mold, place steel wires in the denture mold as a connecting skeleton, prepare a composite resin solution and fill it into the denture mold, and rel...

AI Technical Summary

Problems solved by technology

Due to the special environment of the oral cavity and the special purpose of the teeth, denture materials need to meet the requirements of physical and chemical stability, service life, mechanical properties, biocompatibility and aesthetics. Buckle on the teeth of the oral cavity, remove the medium after solidification, and form a denture mold, place steel wires in the denture mold as a connecting skeleton, prepare a composite resin solution and fill it into the denture mold, and release it after static pressure molding to form a denture base. Composite resin is the base of the denture; however, the steel wire is easily deformed and has no supporting force. The base made of composite resin is hard, and it takes a long time for the denture wearer to adapt, and the internal tissues of the oral cavity are easily worn by the hard base, which is comfortable. The integrally formed denture has the characteristics of easy preparation, but its local performance is poor, such as the smoothness and hardness of the tooth part, the support performance of the base part, the connection performance between the base surface and the oral surface, etc.
