Bolt retention structure integrally formed with artificial crown and manufacturing method of matching bolt channel

Abstract

The invention discloses a manufacturing method for a bolt body retention structure and a matching bolt way integrally formed with an artificial crown, and belongs to the technical field of dental prostheses. The method includes the following steps: (1) collecting the three-dimensional spatial information of the teeth of a patient; (2) designing an artificial tooth crown having a bolt body retention structure; (3) integrally forming and manufacturing the artificial tooth crown having the bolt body retention structure; (4) designing a bolt way structure matching the bolt body retention structure; (5) manufacturing the bolt way structure; and (6) installing the bolt way structure in a denture base of a false tooth in cooperative fixation with a bolt body. The material of the bolt body adoptsa dental zirconium dioxide material, and integral forming can be performed with an adjacent crown of an abutment teeth, so that high precision can be achieved, and processing technologies can be greatly simplified; the size and position of the bolt body can be adjusted according to the widths and heights of tooth bodies, so that individuality manufacturing can be realized; the bolt body and the artificial crown are all the zirconium dioxide materials, so that beautiful wearing can be achieved; corrosion situations cannot occur under oral saliva environments; and convenient wearing on and off of the patient can be realized, and wearing effects and comfort level of false teeth can be improved.

Description

technical field [0001] The invention relates to a plug retaining structure integrally formed with an artificial crown and a method for manufacturing a matching plug channel, belonging to the technical field of dental restorations. Background technique [0002] Dentition defect is a common clinical oral disease. The loss of teeth in patients results in impaired masticatory function, which in turn affects the patient's digestive system and general condition. For the restoration of missing teeth, methods such as removable partial dentures and implant dentures are often used clinically. Traditional removable partial denture repairs often have adverse reactions such as warping, swinging, and mucous membrane compression. A clasp is required, which affects the appearance, and the denture is large in size and poor in comfort. The cost of implant denture restoration is high, or the condition of the patient's jaw is poor, and it is impossible to implement implant surgery. The bolt-t...

Problems solved by technology

[0004] Existing plug-in plug-in attachment dentures ( Figure 1A and Figure 1B ) production steps are complicated, requiring high operating techniques for clinicians and technicians, and the production of plugs is limited to metal materials, which are formed by casting and grinding, or the finished metal plugs are welded to the metal bottom crown of the retained abutment by laser, The production process is complicated; corrosion and peeling may occur in the environment of oral saliva; and the metal is exposed, which is not beautiful
