Abstract

The invention discloses a self-shrinking preformed crown retention joint strip which comprises a functional joint strip, the functional joint strip comprises a force application section and at least two sections of pasting strips, the force application section is used for being attached to the surface of a preformed crown, the at least two sections of pasting strips are arranged at the two ends of the force application section respectively, at least one section of pasting strip is connected with the force application section through a shrinking strip, and the other section of pasting strip is connected with the shrinking strip. The functional joint strip integrally forms an integral structure, the at least two sections of the joint strips are respectively used for being adhered to chewing mucous membranes on the surfaces of alveolar cavities on the lip side and the tongue side of the preformed crown, and the contraction strip is made of a shape memory material. When the retention joint strip is used, after the force application section is attached to the preformed crown, the remaining parts on the two sides are aligned with the lip face and the lingual face of the preformed crown, and force is applied downwards from the two faces to complete attachment of the functional joint strip. The force application section can apply pressure to the preformed crown through contraction of the contraction strip, and the joint strip is convenient to use, simple in operation process, low in requirement for skills of physicians and wide in applicability.

Description

technical field [0001] The invention belongs to the technical field of tooth restoration, and relates to a self-shrinking preformed crown retaining sticker. Background technique [0002] In recent years, the number of people with dental defects in our country has shown an increasing trend, and with the development of the economy, the people's pursuit of the aesthetic appearance of teeth has become more and more intense, and the development of the dental restoration discipline and industry has ushered in a new spring. Among various restoration methods, metal-porcelain full crown restoration has the advantages of high accuracy, superior aesthetic performance, good biocompatibility, and structural stability compared with inlay restoration. Therefore, this type of restoration method has become more patient choice. Glass ionomer cement is often used in clinically cemented restorations. The initial curing time of the cement is 2 to 6 minutes, and the basic curing time is 24 hours...
