What are dental implants? Most people don’t know it very well, and may only have heard of its name and know that it works very well. Let’s listen to oral experts, explain the issues that everyone cares about. What are dental implants? Dental implants are actually restorations consisting of implants and an implant-supported upper denture.
In layman’s terms, dental implants are implants made of artificial materials that are implanted into the alveolar bone in the edentulous area through surgery to replace the root. Make beautiful porcelain crowns, so that patients can have a new tooth in the shortest time. What functions do dental implant materials need to have?
(1) Good biological properties:
Histocompatibility means that the material has a good affinity when it comes into contact with the soft and hard tissues and body fluids of the body after implantation.
Biomechanical compatibility, when hard tissue and body fluids are in contact, the mechanical properties (elastic modulus and other parameters) of the material are similar to those of bone tissue, so as to avoid excessive stress concentration on the interface between the implant and the bone tissue when the implant is stressed.
(2) Good mechanical properties: The planting technology is based on the development of modern mechanical processing. Only good processing performance can meet the needs of morphological design. Occlusion is the basic function of teeth. The implant can bear static and dynamic chewing and occlusal forces, and will not be broken, deformed, and worn during long-term use.
(3) Good processing and forming performance: A large number of standardized implants with the same dimensions and fine surface processing are used clinically, and sometimes individual implant materials are made according to individual anatomical characteristics to restore the defective hard tissue.
(4) Good resistance to disinfection and sterilization: The implant must be strictly sterilized before implantation, so it is required that the implant material used will not be affected by high pressure, high temperature, immersion and fumigation of various disinfection liquids and gases, ultraviolet rays and Degeneration occurs due to radiation exposure and other treatments, and there will be no residual disinfection substances, so as to ensure the safety and success of implant surgery.
How long do dental implants last?
How long the dental implant can last is the first concern of the patient, and also the concern of the implant doctor. The Swedish branemark implant system has a relatively long-term statistical observation report. A 24-year report published in 1990 from the first clinical implant in 1965. Follow-up observations of 4636 implants placed in 759 maxilla or mandible of its 700 edentulous patients,
The 5-year success rate reaches 84% to 92% in the upper jaw and 91% to 99% in the lower jaw;
The 10-year success rate reaches 81% to 82% in the upper jaw and 89% to 98% in the lower jaw;
The 15-year success rate was 78% in the upper jaw and 86% in the lower jaw.
It has been more than 30 years since its earliest implantation in patients, and its restoration and implants are still performing normal functions, so how long the implants can maintain remains to be studied.
For the success of implants, the retention time is an important indicator. In the past, it was considered that the implant survival rate of 5 years was 85%, and the survival rate of 10 years was 80%. The conditions for success are now higher. . Finally, it is suggested that consumers should choose a qualified dental institution, preferably a more professional digital dental institution, which will have better effect and be safer.
