Description
Technical Field
The invention relates to the technical field of complete denture processing, in particular to a complete denture integrated numerical control processing method and system.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
When the teeth are completely lost, the chewing function is seriously affected, the nutrition intake is insufficient, the physical health is affected, and the social and psychological effects of the old are negatively affected by the collapse of the 1/3 soft tissue under the face caused by the missing dentition, so that the life quality and the physical health of the old are further affected. At present, the restoration mode for the dentures mainly comprises classical mucosa supported complete denture restoration and implant supported complete denture restoration, and although the implant denture raised in recent years can better restore and reconstruct the oral functions of dentures patients without teeth, the old people have poorer jawbone conditions, often have systemic diseases, relatively larger risks, psychological resistance, unwilling to perform operations and high cost, and the subsequent maintenance difficulty is high, so that the conventional restoration treatment method for the dentures patients without teeth still adopts the complete denture restoration with non-implant support. In addition, even if the implant support mode is adopted for the toothless jaw repair, the conventional complete denture repair still plays a very important role in the stages of preimplant diagnosis design, intraoperative positioning, osseointegration period transitional repair and the like.
Traditional complete denture processing procedures are tedious, long in period and high in technician experience requirements, and young technicians often do poor complete dentures. The digital repair technology can remarkably reduce the manufacturing difficulty, reduce the manufacturing period and improve the manufacturing efficiency, the direct digital processing method of the complete denture has high manufacturing efficiency, and the cut polymethyl methacrylate (polymethyl methacrylate, PMMA) resin cake has no polymerization shrinkage, high precision and less residual monomer. The most common digital complete denture processing method is a two-step cutting method, namely, a PMMA (polymethyl methacrylate) base color resin cake is used as a material, a denture base with an artificial tooth positioning hole is cut in a numerical control mode, a PMMA tooth color resin cake is used as a material, a single artificial tooth/artificial tooth row is cut or a finished artificial tooth is directly used, and the two artificial teeth are bonded to complete the complete denture. This approach is most widely used in existing complete denture systems, but it is a disadvantage of this approach that the split formation of the base and teeth may create large errors in the bonding of the teeth into place. The one-step processing method can effectively avoid the errors, namely, special cutting resin cakes are used for integrally processing the dentition of the base, and the artificial teeth and the base are not required to be bonded. There are two types of common at present, one is a double-color resin disk, and the gingival margin is required to be dyed in the later period; the other is a specially designed gum color base color interface, the shape of the interface is like a resin disk of a shell, and the gum edge is not required to be treated later, but software matched with the interface is required to be used. Therefore, no complete denture integrated digital processing technology which can be molded at one time without post-treatment of gingival margin dyeing and does not depend on matched software exists.
