Description

One-section type dental implant dental nail Technical Field The invention belongs to the technical field of medical instrument for oral implantation and restoration, and particularly relates to an oral implant dental nail which has an integrated single-section structure and has high-efficiency bone combination and convenient implantation characteristics, and is particularly suitable for an alveolar bone implantation and restoration scene of a patient with tooth deficiency. Background The dental implant restoration is the first-choice restoration mode for patients with dentition defect and dentition deficiency at present, the core component is an implant dental nail, the component is directly implanted into alveolar bone and is used as an artificial tooth root to bear the functions of retention, stress and bone combination, and finally the dental crown is connected to complete the chewing function reconstruction. The dental implant dental nail of the current clinical mainstream mainly adopts a sectional structure and is mainly divided into a three-section type implant and a two-section type implant, wherein the three-section type implant consists of three independent parts of an implant main body, a base connecting section and a repairing base, and the two-section type implant is assembled by two parts of the implant main body and the base. The segmented structure exposes a plurality of technical defects which are difficult to overcome in long-term clinical application, and the technical defects are as follows: 1. the operation flow is complicated, and the wound of the patient is large. The sectional implant needs to finish the operations of implantation, healing, abutment connection, prosthesis installation and the like step by step, generally needs 1-2 times of secondary operations, has a plurality of operation incisions and long operation time, causes great pain in the operation of a patient, and has a soft tissue healing period of up to 3-6 months after the operation, thereby seriously affecting the life quality of the patient. 2. Secondary surgery presents multiple medical risks. After the sectional implant is combined, the gum is required to be cut off secondarily, soft tissues are stripped off to install the abutment, the operation wound is increased, the complications risks such as gum infection, alveolar bone absorption, postoperative bleeding and swelling are greatly increased, and meanwhile medical consumables, labor and time cost are additionally increased in secondary operation, so that the economic burden of a patient is increased. 3. The bone-joining efficiency is low and the retention stability is poor. The traditional sectional implant has the advantages of single smooth thread or common thread structure on the outer surface, limited contact area with alveolar bone, insufficient adhesion and growth space of bone tissue, low bone combining speed and low combining strength, easy loosening and falling of the implant after operation, and even implant failure caused by poor bone combining, and the clinical failure rate is about 5-10%. 4. The drainage of body fluid is not smooth, is easy to cause inflammation. After the traditional implant is implanted, the gap between the implant and the alveolar bone can not rapidly drain tissue fluid and exudates, so that local effusion and bacterial breeding are easily caused, peri-implant inflammation is caused, the alveolar bone is continuously absorbed, and finally the implant is disabled. 5. The method has the advantages of high requirements on machining and assembling precision, high cost, strict requirements on production equipment and process control and high machining reject ratio of parts, and meanwhile, the multi-part assembling process is complex, the assembling error easily causes connection looseness and uneven stress, and the production cost and the later maintenance cost are further improved. 6. The controllability of the implantation operation is poor. The traditional implant has no anti-slip structure on the surface, is easy to slip and deviate in the implantation process, causes deviation of implantation angle and depth, and influences the repairing effect, and the end part of the implant has no guide structure, so that the bone resistance of the cutting alveolar bone is large during implantation, and bone tissue damage is easy to cause, and bone healing is influenced. In order to solve the problems, although some attempts of integrated implants exist in the industry, the existing integrated implants only achieve the core functions of osseointegration, anti-slip, guiding, body fluid drainage, retention connection and the like, which are not synchronously optimized, have the defects of insufficient osseointegration, difficult implantation, unstable retention and the like, and cannot meet the clinical high-efficiency, safe and low-cost planting requirements. Therefore, developing an integrated one-piece structure, which has the advantages of lo
