Description

Technical Field

[0001] The utility model relates to the technical field of dental implants, in particular to a one-stage dental implant system. Background Art

[0002] The dental implant system can implant dental implants into the upper and lower jaws of the human body at the site of missing teeth through surgical procedures. After the surgical wound heals, a prosthetic denture is installed on the upper part to solve the functional and aesthetic problems caused by missing and damaged teeth.

[0003] Traditional dental implants are mostly made of metal materials such as titanium alloy, pure titanium, and tantalum. During clinical use, a potential difference will be generated in the oral cavity, causing electrochemical corrosion, affecting the service life of the dental implant and the abutment and the health of the patient. Due to the particularity of metal materials, some patients will naturally have allergic reactions, causing secondary pain to the patient. Dental implants and abutments made of metal materials are metallic in color. As the patient ages, the gums shrink and the alveolar bone is absorbed, which easily exposes the dental implants and abutments, affecting the beauty of the patient's oral cavity. The neck of traditional metal dental implants is relatively rough, which is very easy to attach plaque, greatly increasing the incidence of peri-implantitis. Traditional metal dental implants are mostly two-stage, with a micro-motion effect between the implant and the abutment, which increases the absorption of the alveolar bone and reduces the success rate of implantation. At the same time, due to the two-stage structure, the strength of the implant or abutment is low, and mechanical complications such as implant or abutment fracture are prone to occur. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a one-stage dental implant system which has no electrochemical corrosion effect, no metal allergy, low incidence of peri-implantitis, low bone absorption rate, beautiful appearance, immediate load-bearing and high strength.

The base is installed on the top of the dental implant. The inside of the base contains an inverted cone structure and a screw channel. The inverted cone structure is installed in cooperation with the shoulder portion. The screw channel is opposite to the internal thread structure. The base screw connects the denture with the base to the dental implant. The dental implant is straight or angled. In the straight dental implant, the axis of the shoulder portion is parallel to the axis of the root. In the angled dental implant, there is an angle between the axis of the shoulder portion and the axis of the root.

[0006] The utility model discloses a one-stage dental implant system, wherein the ceramic material is one of zirconium oxide, alumina toughened zirconium oxide and zirconium oxide toughened alumina.

[0007] The utility model discloses a one-stage dental implant system, wherein the shoulder taper of the shoulder portion is the same as the inner taper of the base, and the range is 10° to 60°.

[0009] The utility model discloses a one-stage dental implant system, wherein the gingival penetration part is in a trumpet shape to simulate the structure of a natural tooth.

[0010] The utility model discloses a one-stage dental implant system, wherein the outer side of the base is provided with straight and annular grooves.

[0013] The utility model discloses a one-stage dental implant system, wherein the angle is 0° to 45°.

[0014] The difference between the one-stage dental implant system of the utility model and the prior art is that the dental implant in the one-stage dental implant system of the utility model adopts a one-stage structural design, which solves the bone absorption caused by the micro-motion effect between the base and the implant and improves the success rate of the implantation operation. The dental implant adopts a one-stage structural design, which improves the strength of the implant and avoids the occurrence of mechanical complications.

[0015] Dental implants and bases are made of ceramic materials, which will not produce potential difference and electrochemical corrosion effect.
