Problems solved by technology

(1) When titanium implants and metal abutments are used to restore the anterior teeth area with high aesthetic requirements, the metal color will be revealed in the case of insufficient alveolar bone depth or thin free gingiva in the primary surgery ;Recent studies have found that titanium metal implants will release metal ions to produce black lines on the gingival margin, which seriously affect the aesthetic effect of dental implant restoration and cannot meet the needs of patients; (2) Titanium metal has high thermal conductivity , It is easy to cause damage to the surrounding gum tissue and bone tissue when heated; (3) After the titanium implant system is repaired, if there are dissimilar metals in the mouth, the two will form a galvanic couple, resulting in galvanic phenomenon, and the patient will feel tingling; (4) Titanium implant system Metal implants and abutments are relatively soft, and they are easily damaged by scalers during periodontal maintenance after implant restoration; (5) It is also found that patients who have been restored by metal dental implant systems will have CT or MRI examinations. Artifacts, which bring inconvenience to the diagnosis of oral and maxillofacial diseases

specific Embodiment approach 1

[0015] As shown in Figures 1, 2, 3, and 4, all devices of the one-stage and two-stage zirconia dental implant systems are made of zirconia.

specific Embodiment approach 2

[0017] As shown in Fig. 1, the device of the one-piece zirconia dental implant system is composed of an implant body part 1, a gingival part 2 and an abutment part 3 as a whole. The diameter of the implant transgingival part 2 is slightly larger than the diameter of the tail end of the implant body part 1, so that the implant is tapered. The surface of the implant body 1 is threaded, and the surface of the thread can be sprayed with hydroxyapatite coating, and a self-tapping groove 4 can be arranged at the tail end. The gingival part 2 is formed by the continuation of the implant part 1. Viewed from the axial plane, the upper end of the gingival part can be designed as a flat linear shape, or it can be designed as a curved shape similar to the edge of the gingiva, like a wave; the surface of the gingival part 2 is smooth, Plaque is not easy to adhere; a shoulder 5 is set at the boundary between the transgingival part 2 and the abutment part 3, and the angle of the shoulder 5 i...

specific Embodiment approach 3

[0019] The two-stage zirconia dental implant system consists of an implant 1 , an abutment 2 and a central retaining screw 3 in FIG. 4 . As shown in Figure 2, the diameter of the gingival part 7 of the implant 1 is slightly larger than the diameter of the tail end and is tapered. The surface of the gingival part 7 is smooth, and the plaque is not easy to adhere to, which is conducive to self-cleaning; the surface of the implant 1 has threads , the surface of the thread can be sprayed with hydroxyapatite coating; the end of the implant 1 can be provided with a self-tapping groove 3, so that the implant can be positioned on the alveolar bone. The outer diameter of the transgingival portion 7 of the implant 1 is slightly larger than the outer diameter of the abutment 2. After the two are connected, the inner diameter of the implant coincides with the outer diameter of the abutment to form a platform 4, which has a platform transfer function. The connection between the implant 1 a...

Abstract

The invention discloses a zirconium oxide tooth implantation system, and is characterized in that all devices are made of zirconium oxide. The system is divided into a one-stage type and a two-stage type. A one-stage type implantation body is provided with screw threads, the surface of a dentogingival part is smooth, and the body is combined with the base station integrally. The surface of the two-stage type implantation body has a smooth type and a screw-thread type, and the implantation body and the base station is embedded with each other by polyhedral angle and Moll's taper and is connected and fixed by the central screw nail. The invention has the following advantages that: the zirconium oxide implantation body without toxic side effect is capable of being integrated with alveolar bone; the total porcelain crown supported by the zirconium oxide base is attractive in appearance; and the zirconium oxide implantation teeth can resist the functionating of good occlusal force without influencing CT and nuclear magnetic imaging inspection.

Description

technical field [0001] The invention relates to oral medical equipment, and specifically belongs to the technical field of dental implantation. Background technique [0002] Since Professor Branemark first applied the cylindrical threaded dental implant made of pure titanium to the clinic in 1965, he created a precedent for modern dental implant. After more than 40 years of development, modern dental implant technology has become mature and clinically applied. It has been widely used and has become one of the important methods for repairing dentition defect and loss. Up to now, there are more than 100 dental implant systems for clinical use in the world. After clinical verification, the two-stage fully buried implant is approved. At present, the dental implant systems used clinically are all made of metal titanium. With the deepening of clinical application and research, it has been found that titanium implant systems have the following defects. (1) When titanium implants ...
