Description

Technical Field

[0001] The utility model belongs to the technical field of fixed dentures, and particularly relates to a fixed denture based on inlays. Background Art

[0002] A fixed denture is an oral restoration method that grinds adjacent teeth and uses them as abutment teeth to support the missing tooth restoration. Its core structure consists of the following three parts: retainer, pontic, and connector; the retainer is the part of the abutment tooth, the pontic is the part of the artificial tooth, and the connector is the structure connecting the retainer and the pontic. The traditional connection method is a full-crown fixed denture, and the artificial tooth is connected through the crown. This method has many disadvantages.

[0003] The full-crown fixed denture needs to grind most of the tooth tissue of healthy adjacent teeth, which may cause pulp exposure or secondary caries, resulting in damage to adjacent teeth. If the adjacent teeth are in poor health, they are likely to become loose or break after restoration, and they cannot be cleaned by themselves. Dental plaque is likely to accumulate between the adjacent teeth and the pontic, increasing the risk of caries and gingivitis and affecting stability; the cost of the full-crown retainer is relatively high, which will increase the production cost. If the pontic is not properly designed, it may break due to excessive occlusal force, and there may also be problems such as insecure bonding and easy detachment.

[0004] Chinese Patent CN107854188A discloses a minimally invasive denture retention device and its installation method. The retention device includes a retention beam, which includes a first installation base and a second installation base. The two installation bases are fixedly connected by bonding, and fixing wings and clamping protrusions are arranged at the left and right ends of the two installation bases. In this application, the retention beam is made and installed at the tooth loss site, and dovetail grooves and retention grooves are ground on the inner sides of the healthy teeth on both sides to fix the retention beam, and the retention beam is used as the abutment tooth for installing the dental crown.

[0005] This patent has a larger wear area on the teeth by setting through grooves on the inner sides of the healthy teeth on both sides, and it is prone to problems such as difficult cleaning. The retention beam and the dental crown are installed separately, and it is easy to fall off during use, and it is easy to cause the healthy teeth to break from the worn part, affecting the firm stability of the denture.
