1. has good retention and stability, and its chewing function is better than that of traditional denture.
2. No damage to adjacent teeth;
3. It has no lasting effect on alveolar bone absorption;
4. As long as there is good osseointegration, it can be used for a long time. According to statistics, the success rate of artificial dental implants is 85% in five years and above 80% in ten years.
Main disadvantages:
1. The treatment cycle is long, usually taking four to six months;
2. The treatment cost is more expensive than general dental implants.
Methods: Pure titanium artificial tooth root was implanted into the patient's jaw, fused with the jaw by bone bonding, and then porcelain crown was installed on it.
At present, imported pure titanium artificial roots (implants) are widely used in dental implants in China, and the prices of different implants are different, generally around 6000-8000, and the more expensive ones are around 12000. In addition, some patients need to do some other necessary examinations and treatments before and after tooth implantation, such as blood routine examination, X-ray film, systematic periodontal treatment, treatment and filling of adjacent teeth, maxillary sinus elevation and alveolar ridge elevation. In this case, the cost of dental implants will increase a lot, but 30 thousand yuan is really too expensive.
In addition, in order to ensure the quality, it is very important to choose hospitals and specialists correctly for implant restoration.
Supplement 1: success rate of dental implant, existing use time. The success rate of dental implants is closely related to implant materials, implant techniques, alveolar ridge conditions of patients, oral hygiene and personal use. With the improvement of implant materials and techniques, the success rate of dental implants is also increasing. I listed a conservative limit earlier, and the statistics of the United States are at least 5 percentage points higher. It is said that some of the earliest patients have been using the function of normal driving for more than 30 years. The introduction time of this technology in China is about 15 years, so it has not been reported for such a long time.
Generally speaking, the service life of removable dentures is 5-7 years, and that of fixed teeth is 8- 10 years. Therefore, the service life of dental implants is much longer than these two kinds of dentures.
Supplement 2: The worst result of planting failure is that the implant is loose and falls off.
The reasons of dental implant failure include indications and improper implant selection; Operation error; Improper design or manufacture of the prosthesis (referring to the porcelain teeth on it); Abnormal force impacts implants (including violent occlusion), etc. The loosening of the upper porcelain crown leads to chain reactions such as food impaction, gingival atrophy and inflammation around the implant. The alveolar bone is absorbed and the implant loosens and falls off.
After missing teeth, dental implants should be the first choice as long as the economic conditions permit, but you must go to a regular hospital and choose a qualified and experienced doctor to do it.
