Full-process digital production method of complete dentures

Abstract

The present invention provides a full-process digital production method of complete dentures, which includes obtaining the three-dimensional data STL files scanned in the mouth of patients with complete edentulous jaws; Relative positional relationship, obtain the three-dimensional data STL file of the centric occlusal tray by scanning; obtain the DICOM file of the spiral CT or CBCT of the edentulous patient wearing the centric occlusal tray; the advantages of this method are as follows: 1. The fitting of the four digital files constructs the three-dimensional space of the patient's maxillofacial region, and sets the occlusal plane of the try-in denture and the shape and position of the anterior teeth with reference to its anatomical structure, so as to improve the try-in effect of the try-in denture. 2. Utilize the final impression scanning and replication technology to accurately manufacture the shape of the final denture base. 3. The final denture is obtained by bonding different colors and high-strength resin discs that are cut separately with an adhesive to obtain the base and artificial dentition. The cutting precision is high, the strength of the resin disc is high, and the artificial teeth have good wear resistance.

Description

technical field [0001] The invention specifically relates to a full-process digital manufacturing method of a complete denture. Background technique [0002] According to the existing clinical experience, a pair of biofunctional complete dentures with good adsorption properties can be produced. In the traditional technology, the production steps include: [0003] S01: Select a suitable finished product tray to make the initial impression of the upper and lower jaws, and pour the initial model; [0004] S02: Use the centric occlusal tray to record the occlusal relationship between the upper and lower jaws, and transfer the relationship to the simple jaw frame; [0005] S03: Make a personalized tray and wax embankment on the initial model; [0006] S04: Install a gothic arch tracing device on a personalized tray; [0007] S05: Use the personalized tray to make the final impression in the mouth, and use the Gothic bow to record the horizontal jaw position relationship, and u...

Problems solved by technology

The Chinese patent with authorized notification number CN111743648A discloses a centric occlusal tray, a method of use and a method for making digital complete dentures. The centric occlusal tray can obtain the relationship between the upper and lower jaws and the dental The occlusal plane, the post-production dentures are used to verify the correctness of the occlusal relationship. If it is incorrect, a series of corrections are required, and the process is more complicated
