Embodiment Construction

[0019] The process of using local reinforcement technology to make bonded bridges is the same as that of traditional reinforced fiber bonded bridges: first, prepare the abutment teeth; then make impressions and pour super anhydrite; secondly, select the resin material of the corresponding color through colorimetry; finally The resin is built up in layers and cured in layers until the final shape.

[0020] Before the resin is layered and solidified, it is first necessary to select a suitable bracket according to the size of the restored tooth. Take the bonding bridge of the first molar as an example to illustrate: if the characteristic dimensions of the restoration are shown in Table 1, then the bracket can be determined to the specifications shown in Table 2 according to the requirements of the content of the invention.

[0021] After the bracket is determined, the accumulation and curing of the resin can be started. During this process, stents should be embedded at the cor...

Abstract

A glass fibre reinforced composite resin adhesive bridge for repairing the back teeth deficiency in oral cavity features that a rectangular supporting frame is additionally arranged at the proper position in occlusal region and a rectangular hollow supporter is additionally arranged at the proper position in the connection region. Its advantages are high strength and high load-bearing power.

Description

technical field [0001] A glass fiber-reinforced composite resin bonding bridge is mainly used for oral restoration of missing posterior teeth. Background technique [0002] With the improvement of people's living standards, changes in diet structure, population aging and other factors, the number of dental patients in my country has increased sharply. The second national oral health epidemiological sampling survey shows that: in our country, each person has 2.5 decayed teeth on average; my country has entered an aging society, and people over the age of 60 account for 10% of the total population. At present, about 3 billion teeth in the country need to be filled, and about 1.3 billion "dentures" need to be inlaid. Among them, the phenomenon of missing posterior teeth due to dental caries and other factors is very common. At present, there are mainly three repair methods as follows: [0003] (1) Double-ended fixed bridge This is a restoration method widely used clinically...
