Description

Denture buckle assembly capable of inserting a card with a real tooth

The invention relates to a denture fastener assembly capable of inserting a card with a real tooth, in particular to a buckle assembly provided with an alignment structure.

Traditional dental implant surgery is performed on the patient's intended tooth implant, the gingival flap of the implant is opened, the alveolar bone is exposed, and the dental implant is drilled on the alveolar bone to form a bone cavity. After that, the artificial root of the implant is implanted into the bone cavity, so that the artificial root can be buried in the bone cavity and gradually integrated with the alveolar bone. In the above-mentioned dental implant surgery, since the implant is nailed into the alveolar bone, the oral cavity communicates with the blood vessel of the alveolar bone. If there is a slight gap around the implant, bacteria and food residues will permeate into it. Accumulation can easily lead to swollen gums and atrophy of the bones. In severe cases, bacteria may enter the blood vessels along the implants, thus affecting general health. Therefore, after traditional implant surgery, patients must pay great attention to cleaning to avoid other problems of subsequent complications.

Furthermore, the implants of these implant methods have a stress concentration at the lowermost end of the implant when the force is applied. On average, the human posterior teeth have a occlusal force of about 40 kg, which means that the lower end of the implants The point is repeatedly subjected to these occlusal stresses every day. When the implants create a gap due to stress, the chance of inflammation around the implant is increased. As a result, many patients have problems such as the loosening of the implants and the penetration of the implants and the flesh into the food, and the problems such as purulent pain and bacterial erosion have begun to occur, resulting in a crisis of inability to implant the teeth.

In order to avoid the aforementioned problems, the availability of detachable cap-type cartridges has succeeded in improving the aforementioned problems that conventional dental implant technology may face. These cap-type cartridge teeth can be attached to the denture by means of a snap-fit component provided on the real tooth. In this way, not only the gap generated after implanting the implant can be avoided, but also the bacterial infection is caused, and the denture is detachably coupled with the real tooth through the buckle assembly, so that the denture can be removed and cleaned. Traditional fixed implants are much hygienic. As mentioned above, in order to avoid the lateral stress caused by chewing during the patient's eating, the denture is indirectly transmitted to the buckle assembly through the denture, which causes the buckle assembly to loosen or even fall off under long-term stress, how to make the card The buckle assembly can be firmly combined with the real teeth, which is self-evident. However, if the fastener components are firmly combined with the real teeth, the deep gap is cut in the real teeth, and the patient is inevitably uncomfortable during the operation.
