Description

Single-section type internal hexagonal oral implant dental nail Technical Field The invention belongs to the technical field of oral medical appliances, in particular to an oral implant dental nail with an integrated structure, which is particularly suitable for alveolar bone implantation repair operation after permanent tooth loss, realizes single implantation, high-efficiency bone integration and stable retention through structural optimization, and belongs to technical improvement of dental implantation repair core components. Background The missing teeth are clinically common oral diseases, and the dental cast or unplugged can be caused by trauma, decayed tooth, periodontal disease and the like, so that not only the chewing function and the facial beauty of a patient are affected, but also a series of oral problems such as alveolar bone absorption, adjacent tooth inclination and the like can be caused. The dental implant restoration is a preferred scheme for restoring the missing teeth at present, the core component of the dental implant restoration is an implant dental nail, and the structural design of the dental nail directly determines the success rate of implant surgery, the healing efficiency after surgery and the long-term use stability. The existing oral implant dental nails mainly used in clinical mainstream are of a three-section split structure, and are mainly formed by assembling three independent components of an implant base station, an intermediate connecting section and an implantation repairing section, wherein the structure exposes a plurality of technical defects which are difficult to solve in long-term clinical application; and the contact area of the dental nail and bone tissue is limited, the bone cell adhesion and growth speed are slow, the bone combination period is long, the survival rate is low, and the implant is easy to loosen and fall off. Secondly, the head of the three-section dental nail is only connected by adopting a simple plane or threads, a special clamping structure is not adopted, the binding force between the head and the upper repairing part is insufficient, the repairing body is easy to loosen and shift after long-term chewing stress, and the service life and the use safety of the implant are influenced. Furthermore, the end part of the traditional dental nail is a flat mouth or a small-angle conical head, so that the resistance is large when the dental nail is implanted into an alveolar bone, a doctor is difficult to accurately control the implantation depth and angle, the alveolar bone is easy to crack and the implant is easy to deviate, and the probability of operation failure is increased. Finally, the three-section split structure needs to process three independent parts respectively, then high-precision assembly is carried out, the processing technology is complex, the cost is high, bacteria are easy to remain in an assembly gap, postoperative infection is caused, and the overall qualification rate and clinical applicability of the product are poor. Aiming at the pain points in the prior art, an implant dental nail with a simplified structure, convenient operation, high bone integration efficiency and stable retention is needed in the industry so as to solve the inherent defects of the three-section dental nail and improve the clinical effect of dental implant restoration.
