Why does dental implant fail?

Dental implants have become the most common treatment option for the restoration of missing teeth, and it is also a future treatment trend. However, there is a certain chance that dental implants will lead to failure. Although it is very small, it is still heard.

Let me give you two extreme examples

The first patient in human history to receive a titanium implant-Gosta Larsson. Gosta Larsson passed away in 2005. At the time of his death, his dental implants were still intact. His dental implants have accompanied him through 40 years of life.

The implant with the longest lifespan is maintained by Sven Johansson, the second patient in the world to have dental implants. Sven has received 6 implants in the upper jaw and 5 implants in the lower jaw. It has been used for nearly 50 years. Dental implants that have been used for 50 years.

In 2014, there was an evaluation of 7711 implants from 23 different medical teams, followed by an average of 13.6 years, and finally found that the success rate was 94.6%. This means that 94.6% of patients can continue to use implants after 13.6 years without replacement. Some people will misunderstand that 94.6% of patients took 13.6 years and then needed to replace the implants.

Planting process

At present, with the development of science and technology, the success rate of dental implants is generally around 95%, and the doctor’s skills can reach more than 98%. Dental implant is a medical behavior, no one can keep the success rate at 100%, only doctors and patients work together to infinitely approach 100% possibility.

The definition of dental implant failure is different. Overall, the initial surgical contact failure rate of dental implants is 1%-5%, and the failure rate after long-term use is between 2% and 10%. The main reasons for the failure of dental implants are incomplete pre-assessment, personal health factors of the patient, and inadequate oral cleaning.

After dental implant restoration

Strict implant inspections must be carried out before dental implants. The patient’s physical condition, oral CT calculation, dental system and density calculation, occlusal records, etc., can be implanted only if these are suitable, which is also a prerequisite for dental implants.

Implant placement CT

Infection is the main reason for the failure of dental implants. For patients with insufficient bone mass, bone meal or other devices must be filled before the implant to strengthen the stability, but the growth of these bones must be assisted by good blood circulation. However, if infection occurs during the operation, the joint between the implant and the bone will be affected, and the artificial tooth root will loosen.

Dental implant failure

Although dental implants are not major operations, wound healing also requires nutrient supply, and nutrition in the oral cavity depends on blood circulation. However, the nicotine in cigarettes will constrict blood vessels and inhibit blood circulation, resulting in reduced wound healing ability, and also Increased the chance of infection. After the dental implant surgery is completed, smoking must be quit, and many patients with dental implant failure are also related to smoking.

Tobacco stained teeth

Poor oral hygiene not only affects the growth of artificial tooth root implants, but also has a key impact on later use. Many patients have long-term inflammation and infection due to periodontal disease and poor oral cleaning after artificial dental implants, which will shorten the life of artificial dental implants.

Dental implants can restore more than 90% of the chewing ability of missing teeth. After all, they cannot be compared with the original teeth. If you often eat too hard food, have the habit of grinding teeth, often chew betel nuts, etc., excessive use of dental implants may also shorten the chewing ability. Service life.

Periodontitis

Generally speaking, the length of artificial tooth root is about 8mm or more. Research has found that under ideal conditions, after 10 years of use of artificial tooth root, the surrounding bone will absorb about 1mm. Therefore, under normal circumstances, there is more than 80% chance of a successful artificial tooth implant, which can be used for at least 20 to 30 years.

Dental implants

Clinically, it has been found that some periodontal patients neglected the cleaning of oral hygiene, which shortened the artificial tooth root by 2 to 3 mm in just one year, which greatly shortened the life of artificial tooth implantation, and finally had to re-implant the tooth. Dental implants are not done once and for all, and more attention should be paid to the cleaning of the oral cavity in order to be used for a longer time.

Don't be too nervous after the implantation fails, you can take it out and wait for the bone to heal before implanting, or you can use other repair methods.
