What Are Common Dental Implant Failures?

The implant is the most advanced option today to replace lost teeth. However, the risk of implant failures may still occur subjectively and objectively by the patients or physicians.

How to know if the dental implants are in trouble? What are common dental implant problems? How to solve them? Invite you to LN Dental clinic.

Implant failures in restoration

Some people are too happy to have new teeth that they eat and chew well.  Sometimes, not following the doctor’s instructions, trying hard food will result in broken or cracked restoration.

The patients do not take care of oral hygiene and keep restoration good frequently, leading to inflammation and affecting the implant abutment.

If you are in this case, you can visit the clinic IMMEDIATELY. The doctor will examine to adjust the correct occlusion and start with a new restoration.

Implant failures in implantation

Failure in implantation may have one or more of the following clinical signs: having a sensation of a wobbly implant; swelling in the implant area, soreness, pus, or bleeding; recognizing bone digestion around the implant site through X-ray images.

If the implant is not fully integrated bone, it should be diagnosed as soon as possible to avoid further alveolar bone resorption, causing new difficulties and may impact the aesthetics when re-implanting.

Situation 1: Loose implant

Once the implant is loose, it is necessary to remove it immediately. The next treatment depends on the implant site – the front or molar teeth, the degree of infection, the bone resorption, and the ability to achieve initial stability with the new implant.

Countermeasures for implant failure include:

  1. Replace the damaged implant with a new one with a larger diameter.
  2. Bone regeneration treatment, bone grafting at the same time with the implant replacement
  3. Treatment stage by stage, firstly regenerating tissues (hard tissue and soft tissue), then conducting the implantation after the wound has healed.

In case there is no inflammation, enough bone volume, and thick bone wall, it is possible to conduct a new implant, can make a new restoration after three months.

Situation 2: Dropping implant

It is necessary to remove the inflamed granular tissue and infected bone and then re-evaluate the tissue to plan the appropriate implant to ensure the success of the implant.

If there is a lot of bone digestion, an artificial bone graft or cubic bone graft is required to increase bone volume. The new implant will be conducted after 6-8 months.

If the patients do not want to continue the implant procedure, other restoration options may be considered.

Recommendations to prevent tooth implant failures

Cases of implant failure are now relatively rare in hospitals, dental addresses. But it is a nightmare for patients and doctors once they happen. In many cases, this risk can be avoided by planning a proper treatment and careful performance process in the dental clinics with modern equipment, carried out by a trained doctor in the implant.

“Systemic and local” risk factors such as diabetes, radiotherapy, smoking, oral hygiene, periodontal disease or history of periodontal disease, bone type, and other significant bone density will result in the implant treatment.

Clinicians need to assess the risk ratio – the advantages and disadvantages of each case, plan treatment and anticipate risk factors before treatment.

When the patient’s risk factors are uncontrolled, the dental implant’s ability to fail and complications may still occur despite the corrective efforts. Sometimes there will be many problems at the same time.

Therefore, patients and treating physicians need to comply with preventive measures to cope with systemic and local risk factors. If these risk factors have not been addressed yet, the dental implant treatment plan should be eliminated, and choose other alternative treatment options.

Finally, if the doctor determines that the case or patient exceeds their capacity, they should recommend a dental implant specialist who is more suitable for the patient.

Some important notes:

  1. For unsuccessful implants due to infection, granular tissues and dead cell layers must be scraped off before having new implantation (if possible)
  2. There must be enough soft tissue and hard tissue when transplanting. In the case of bone deficiency, it is necessary to increase bone growth at the implantation area, especially the aesthetic teeth site – front teeth.

The dental implant is a perfect solution. However, it is carefully to choose clinics and doctors. Surgical performance is high requirements in all aspects, such as the doctor’s technique, medical equipment, and the patient.
