Description

The structure of dental implants

This creation is about the structure of a dental implant, especially a dental implant structure that uses a buffer ring to concentrate the external force on the abutment on the implant.

Dental implant is a dental restoration technique that uses artificial tooth roots to install dentures to make up for missing teeth; artificial tooth roots are also called implants. The root of the tooth that replaces the natural tooth becomes the foundation for installing the crown. After the patient's alveolar bone and the implant are closely combined, the denture crown can be installed on the implant. Installing dentures through artificial roots can not only provide occlusal force close to natural teeth, but also have better comfort and aesthetics than traditional removable dentures and bridges. After dental implants, if you can keep your mouth clean and hygienic, and receive regular dental checkups, you can maintain Under good conditions, dental implants can be used for a long time and thus become an important method of restoration of missing teeth.

When teeth are missing, the function and appearance of the missing teeth can be restored by three implant methods, including implants, fixed dentures, and removable dentures. Among them, dental implants use artificial roots (implants) to fix the crowns to beautify the appearance and maintain chewing power.

After the conventional dental implant is installed in the oral cavity of a dental patient, because the dental implant is a foreign object, when it is installed on the dental implant, it has less cushioning force after being subjected to the bite force and occlusal force. Therefore, When dental patients use dentures for chewing, compared with real teeth, there is a big difference, and they do not have the same elasticity as real teeth, which will cause patients to reject dental implants and have a gap in their psychological expectations.

Continuing from the above, when the tooth is stressed, the periodontal ligament on the tension side is straightened and slightly stretched, and transmits the force to the alveolar bone; in the compressed part, the periodontal ligament has the function of buffering the pressure to avoid the alveolar bone. Excessive impact, and can protect the blood vessels and nerves in the apical area and the periodontal ligament; while the conventional dental implant, when its abutment is stressed, the force transmission is uneven, and there is no periodontal ligament in the compressed part. Buffering will lead to the loosening of the implant and the failure of the dental implant. In order to solve this problem, the industry needs a dental implant structure that can effectively transfer the external force on the dental implant to the harder alveolar bone.

In view of the above-mentioned problems of the prior art, the present invention provides a structure of a dental implant, which includes an implant, a buffer ring and an abutment. The external thread of the implant is used to fix the alveolar bone of the human body, and the implant is An upper outer edge is provided with a limit portion, the limit portion is sleeved with a buffer ring, and a support is arranged above one of the buffer rings. The body of the support is in contact with the implant and the upper part of the buffer ring. The screw is arranged under one of the main bodies, and the screw is correspondingly screwed to the inner thread of the implant; this structure is used to receive the lower pressure on the abutment, so that the buffer ring is concentrated on the implant, so as to avoid uneven stress on the overall structure and increase the The service life of dental implants.
