Digital integrated forming method of false tooth attachment

Abstract

The invention discloses a digital integrated forming method of a false tooth attachment. The digital integrated forming method includes the following steps of 1, three-dimensional laser scanning; 2, data acquisition and processing; 3, 3D printing forming of the false tooth attachment. In the first step, according to an anterior tooth region implant fixing bridge, an extracoronal elastic attachmentfemale part, a posterior tooth region removable denture and an extracoronal elastic attachment male part which are made by an edentulous jaw model, a plaster model is prepared, white developing powder is sprayed to the metal portion of the model, a fixing bridge model is put on a laser scanner rotary table, a non-contact type three-dimensional analog converter is switched on, a horizontal laser beam is emitted to scan the plaster model, the scanning range is determined, after one face is scanned, the rotary table rotates by 90 degrees, and the other regions are scanned. After reconstruction is completed, images are clear, nest ditch pits and the attachment are accurate in structure, no obvious scanning blind region exists, convenience and rapidness are achieved, the false tooth attachmentis rapidly formed, and high efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of attachment dentures, in particular to a digital integral molding method for denture attachments. Background technique [0002] Attachment denture is a kind of removable partial denture, movable-fixed denture or fixed bridge with attachment as the main retention form. It is a special repair method for dentition defect or missing dentition. Gradually improving, it is no longer limited to simply restoring structure and function, but also puts comfort, convenience and aesthetics at the same position. Most patients are quite critical of the retention methods of traditional dentures. For example, the snap ring of removable partial dentures affects the appearance. , the base range is large, it is easy to cause a lot of discomfort, poor condition, poor retention; the condition of the complete denture is poor, it cannot be repaired or the repair effect is not reliable; the problem of leaving the remaining tooth ro...
