Dental implantation structure capable of randomly adjusting angle

Abstract

The invention discloses a dental implantation structure capable of randomly adjusting an angle, which comprises an implant, a connector and an abutment. The outside of the implant is provided with a screw thread; the center of the upper part of the implant is provided with a cylinder; the upper part of the cylinder is provided with a screw thread; the center of the connector is provided with a hole; the upper part of the connector is provided with a grooving; lug blocks at both sides of the grooving are provided with screw holes; the lower part of the abutment is provided with a bump in fit with the grooving of the connector; and the bump is provided with a hole; the connector is connected with the implant by a nut and is connected with the abutment by a screw. The angle between the abutment and the implant can be randomly adjusted, so that a bone region around the implant, which is rich in bone mass, can be sufficiently utilized; regions such as the maxillary sinus, the mandibular canal and the nasal cavity which are absolutely dangerous for the dental implant are avoided; and meanwhile, excellent common path insertion is obtained and the dental implantation structure has high clinical application value.

Description

technical field [0001] The invention relates to an oral cavity dental implant structure, in particular to an implant structure whose angle can be adjusted arbitrarily. Background technique [0002] In the 1960s, Professor Branemark of Sweden founded the theory of "osseointegration" of titanium, which laid the theoretical foundation for dental implants. Dental implants have become one of the main restoration methods for missing teeth due to their strong chewing force, beautiful and comfortable appearance, and no harm to adjacent teeth. [0003] If the alveolar bone or one side of the missing tooth is severely resorbed, especially the maxillary sinus, mandibular canal, and nasal cavity, which are dangerous areas for dental implants, various types of bone grafting and periosteum-guided bone tissue regeneration can be used , distraction osteogenesis, maxillary sinus lifting and other techniques to restore the width and height of the alveolar bone, or mandibular nerve transfer t...

AI Technical Summary

Problems solved by technology

[0007] 2. The angle between the abutment and the implant has been fixed, and the angle between them can reach 30-60 degrees, while the abutment cannot rotate along the central axis of the implant

[0008] 3. The angle between the central axis of the abutment and the central axis of the implant is fixed, and the abutment can rotate 360 ​​degrees along the central axis of the implant, but the angle of the abutment relative to the implant cannot be adjusted

[0009] 4. The abutment and the implant are connected by a hinge, and the hinge has a partial spherical structure, such as the patent application disclosed in CN1022...
