El rejection of a dental implant It occurs when the body does not properly accept the implant placed in the maxillary or mandibular bone. Although dental implants have a Success rate over 95%, in some cases complications may occur.

It is essential to identify the symptom in time to avoid more serious problems.

 

How does rejection of a dental implant manifest?

Symptoms may vary, but the most common are:

  1. persistent pain  (not to be confused with normal postoperative discomfort).
  2. Implant mobility: A successful implant must be completely fixed.
  3. Swelling and redness around the gum.
  4. Spontaneous bleeding or when brushing.
  5. Suppuration (presence of pus) indicative of infection.
  6. Swollen face from dental implant, especially if it persists for more than a few days.

 

How long does it take for the body to reject a dental implant?

Rejection can occur in two phases:

  • Early rejection: It occurs in the first 3-4 months after implant placement. It is usually due to poor integration with the bone or infections.
  • Late rejection: It may even appear after years, due to chronic infections, peri-implantitis or occlusal overload.

 

Dental implant rejection after years

How do you know if your body is rejecting a dental implant?

If you notice any of these symptoms, go to your dentist immediately:

  • Intense pain or that increases over time.
  • Swelling abnormal that does not decrease.
  • Infection in the dental implant (symptoms such as pus or bad smell).
  • Mobility of the implant.

Important: Pain in a dental implant after years could indicate late rejection or peri-implantitis.

Causes of dental implant rejection

  1. Peri-implant infections (peri-implantitis).
  2. Dental bone graft rejection, if a previous one has been done.
  3. Bad implant placement:Incorrect placement may cause inadequate distribution of forces, damage nearby anatomical structures, or affect osseointegration.
  4. Systemic diseases uncontrolled such as diabetes.
  5. Smoke in excess.
  6. Oral hygiene deficient.
  7. Mechanical overload or malocclusion.

Risks of dental bone graftIn the event of rejection of an implant: Graft loss, infection or insufficient integration.

Can dental implant rejection be caused by poor placement?

Yes, may be caused by poor placementAlthough the term “rejection” is often associated with a reaction of the body to the implant material (which is very rare because titanium is highly biocompatible), in most cases, what is interpreted as rejection is actually a failure of osseointegration, and one of the most common factors is incorrect placement.

If you suspect that an implant may be poorly positioned, the ideal thing to do is to perform a 3D X-ray (CBCT) to assess the exact position of the implant and the integrity of the surrounding bone.

Badly placed dental implant rejection

When should a dental implant be removed?

It is recommended to remove the implant if:

  • There significant mobility.
  • There is a persistent infection that does not improve with antibiotics.
  • El Pain is constant and affects the quality of life.
  • The implant is misplaced, causing damage to the bone or gum.

Solution for dental implant rejection

  1. Early diagnosis by X-rays and clinical evaluation.
  2. Infection treatment if present.
  3. Removal of failed implant, if required.
  4. Guided bone regeneration before placing a new implant.
  5. New implants with better surgical techniques and biocompatible materials.

FAQs

  • I have lost a dental implant, what do I do? See your dentist immediately. Do not try to reposition it yourself.
  • Dental implant rejection after years, is it possible? Yes, it may be due to peri-implantitis, overload or poor placement.
  • Dental bone graft rejection: is there a solution? Generally yes, with a new graft or bone regeneration techniques. In these cases, it is important that you put yourself in the hands of a dentist with experience in advanced bone regeneration cases. Dr. Alejandro Prieto is a reference in this area.
