Description

Combined cobalt-chromium alloy porcelain tooth support

Technical Field

The utility model relates to the technical field of dental medical instruments, in particular to a combined cobalt-chromium alloy porcelain tooth bracket.

Background

Teeth are the hardest organs of the human body, and have the functions of keeping the facial appearance, assisting pronunciation and the like besides the functions of incising and biting, chewing and the like. Teeth can be classified as incisors (incisors), cuspids (tiger teeth), premolars, and molars. Each tooth is composed of a crown exposed outside the alveolar bone, a root growing inside the alveolar bone, and a neck between the crown and the root. The main constituent of a tooth is dentin (dentin), which is surrounded by enamel (in the crown portion) and cementum (in the root portion). The cementum is also provided with periodontal ligament composed of fiber for fixing teeth in alveolus. The center of the tooth is provided with a pulp cavity filled with pulp and rich blood vessels and nerves. Along with the gradual improvement of the social living standard, the requirements of people on healthy teeth beautification are higher and higher, and the regret is made up by a way of imbedding porcelain teeth for patients with teeth deficiency. At present, in the clinical practice of dentistry, before the porcelain tooth is cast in, a dentist firstly grinds a tooth gap on two lateral abutment teeth by a lathe so as to be beneficial to the porcelain tooth bracket to be sleeved in the tooth gap and used for reinforcing the porcelain tooth, and in addition, a layer of tooth glaze surface of the two lateral abutment teeth needs to be grinded by the lathe so as to be beneficial to the abutment teeth sleeved in the tooth socket to accord with the previous occlusion state. Because the enamel is the hardest part of the tooth and is a natural protective layer of the tooth, the anti-damage capability is reduced after the enamel is grinded by a lathe, the tooth is easy to be decayed, in addition, the pain stimulation to the dental pulp nerve is caused by the instantaneous high temperature generated in the process of grinding the enamel by the lathe, even if nerve block anesthesia is carried out in advance, the tooth enamel is difficult to endure, and simultaneously, more tooth hidden troubles are brought to the patient later.

When the prior combined cobalt-chromium alloy porcelain dental stent is used, the following problems can exist:

1. the combined cobalt-chromium alloy porcelain tooth support used at present is not suitable for different crowds due to the fact that the distance between tooth sockets is fixed and the oral cavity of each person is different in size, and practicability is reduced.

2. When the existing combined cobalt-chromium alloy porcelain tooth bracket is installed, the fixing plate may scratch the palate of a user, the user may move around, and inconvenience is brought to the installation of a doctor.
