What is dental implant Dental implant is not really planting a tooth or several teeth like natural teeth, but is a “denture” restoration method in which the implant material is embedded into the alveolar bone (implant), and then a denture is made on top of it. It is a kind of missing teeth restoration method based on the lower structure implanted in the bone tissue to support and fix the upper dental prosthesis. It consists of a lower supporting implant, a linking device and an upper dental prosthesis. Dental implants are one of the restorative techniques for missing teeth nowadays. Advantages of dental implants 1, dental implants have high stability, not like ordinary movable dentures may fall off when eating or talking; 2, artificial tooth roots are deeply planted in the alveolar bone, functional stimulation of the alveolar bone, can protect the alveolar bone structure, to avoid its atrophy; 3, protection of neighboring teeth, dental implants rely on their own roots to exist independently, and do not need to grind or just a little adjusted to grind the health of the teeth, will not cause dentures and healthy teeth contact surface. Food embedded in the healthy teeth caused by new caries; 4, solid artificial tooth roots: dental implants through the base of the fixed device on the pile, the upper denture fixed, good fixation and stabilization can increase the sense of comfort, have a good chewing power; 5, dental implants beautiful appearance, like natural teeth, when you speak the facial expression as natural as the original, to increase your self-confidence. Disadvantages of dental implants 1, the price of dental implants is relatively expensive. 2, dental implants are not suitable for all people to do, the general condition is good, physical and mental health, bone and teeth development has been stereotypes of adults suitable for dental implants, such as bleeding disorders, high blood pressure, heart disease, diabetes and other systemic diseases, in the treatment of the disease stabilization before accepting the dental implant surgery; allergic to titanium metal can not be done. Dental implant success rate In the mid-1980s, foreign scholars put forward the implant 5-year success rate of more than 85%, 10-year success rate of more than 80%. With the improvement of implant technology and the perfection of implant system, most of the recent literature reported that the 5-year success rate of implants is above 95% and the 10-year success rate is above 90%. Longer implants have been reported to have been used successfully for more than 40 years.
