After a failed implant, it is usually possible to have another implant. However, it is important to find the cause of the first failure and to reflect on it and take appropriate countermeasures. After the extraction of the implant, you should wait 3-6 months for the local bone tissue to fully grow before considering the implant again. The older the patient, the slower the recovery of the alveolar bone. Generally speaking, the success rate of re-implantation is slightly lower than the initial one. Implant failure includes the following reasons, such as contamination of the implant, loss of bone, which can lead to poor stability of the implant and implant failure. There are also the patient’s own conditions, such as patients who smoke or drink more alcohol, which can also affect the survival rate of the implant in the mouth. There is also a situation where the patient eats with the implant during the recovery period within three months, which also affects the time the implant stays in the mouth and leads to failure. The above-mentioned situations lead to the failure of dental implants. It is important to analyze the causes and to exclude these factors when restoring the implants again in order to make them successful again.
