Technology and structure of fused light composite epoxy resin on the surface of inner crown

Abstract

The invention aims to provide a method for fusing the light-curing composite epoxy resin material on the surface of an inner-layer tooth crown body and a structure thereof. The invention is characterized in that the zirconium dioxide material or the metal material for burning porcelain teeth is adopted during the surface treatment and the automatic grinding (model stacking) of an inner-layer tooth crown body, wherein the inner-layer tooth crown body is coated with a coating modifier to rough the surface of the inner-layer tooth crown body. Meanwhile, the structure of the tooth crown body is built up by means of the coating layer fused with the light-curing composite epoxy resin material and is ensured to be firm and durable. Meanwhile, the pressure generated during the collision of a dental implant body and a natural tooth can be reduced effectively, so that the ervice life of dental implant body is prolonged effectively.

Description

technical field [0001] The invention relates to a technique and structure of a dental prosthesis, in particular to a dental crown with zirconia material or metal material for firing porcelain teeth as the surface of the inner crown body using physical characteristics, mechanical principles or chemical Methods and other technologies combined with the process and structure of light composite epoxy resin. Background technique [0002] A denture consists of a bottom-up implant and a crown; and the current restoration techniques for the crown generally fall into the following categories: [0003] 1. The repair technology of using metal firing ceramic powder; 2. The repair technology of using metal surface particles and then mechanically bonding composite resin; 3. The repair technology of using zirconia firing ceramic powder; 4. Heating and dissolving alumina , After die-casting, the repair technology of sticking to zirconia; 5. After heating, dissolving and die-casting lithium ...

Problems solved by technology

[0009] In addition, generally speaking, all-ceramic crowns are more expensive than metal-ceramic teeth. Therefore, if the production technology of photo-composite epoxy resin can be applied to metal-ceramic teeth, it will be beneficial to make materials similar to all-ceramic crowns at a lower cost. The quality and strength of the prosthesis, but the current metal-ceramic bonding technology between metal and ceramics is still unable to combine the surface of the metal material with light composite epoxy resin, and the technical level is still at the level of purely mechanical bonding such as casting. , its strength is poor, causing the crown body to easily peel off with the use of time
