Description

Forming device for dental monolithic restorations

The present disclosure relates to a molding device that can be used for dental restorations, especially a molding device that can be used for single-piece dental restorations.

Dental restorations can generally be divided into full-face crown restorations or monolithic restorations. The dental crown restoration system is used for damaged teeth that need to be completely covered, such as tooth trauma or tooth decay caused by incomplete teeth. After repairing the affected tooth, it is polished and resized, and then the crown restoration is placed on the original tooth. superior. In contrast to crown restorations, monolithic restorations are used to improve the appearance of teeth and can be used to treat, for example, broken or fractured teeth, severe discoloration or uneven coloration, large gaps between teeth, smaller than average teeth, canines or Shaped teeth, etc., and more widely, can be used for dental beauty to make the dentition more tidy.

Whether it is a full-face crown restoration or a single-piece restoration, both are customized dental procedures because the dental restoration needs to fully fit the size of the individual teeth. In the prior art, when making a single-piece restoration, it is necessary to remove about 0.3 mm to 0.5 mm of tooth enamel, then remove the impression of the tooth to make a mold, and then make a single-piece restoration according to the mold. Before the tooth to be repaired, it is necessary to ensure the tightness of the restoration and the tooth, and then completely adhere to the tooth to be repaired and remove the excess adhesive, and finally adjust and modify the single-piece restoration.

In recent years, the production of dental crown restorations or single-piece restorations can be produced by 3D printing technology, that is, after removing part of the enamel of the teeth, a 3D stereo camera is used to take images, and the computer automatically simulates the tooth shape of the repaired part. After the restoration is completed, the restoration is cemented to the tooth to be repaired, the excess cement is removed, and the restoration is adjusted and modified.

Generally speaking, if the shape of crown restorations or single-piece restorations does not fit the teeth, it will not only cause poor appearance, but also cause problems such as tooth decay, gingival inflammation, atrophy, and even more serious periodontal disease. Furthermore, tooth enamel protects the outer layer of teeth, so reducing tooth enamel may also have a negative impact on the tooth itself.
