Why do Implant Fails ?
Planning before a dental implant procedure
Proper planning by a surgeon entails the doctor completing a thorough examination of your mouth to assess the health of your gums and jaw bone.
Dental X-rays give your surgeon and idea of your overall oral health, thus providing clues as to whether a dental implant will succeed.
Planning also involves an understanding of your medical history. This includes any medical conditions you have, as well as any medications you take.
When there’s a lack of understanding or proper planning, a surgeon may proceed with a dental implant even when the person isn’t the right candidate for one.
This can cause improper placement of the implant and stress at the implant site, resulting in the growth of aerobic bacteria which can trigger infections or an abscess.
Careful planning is also how your surgeon identifies issues that could interfere with an implant. For example, you may need a sinus lift before getting an implant to ensure success.
As you look for an experienced surgeon, talk with friends or family who’ve had a dental implant and ask for their recommendations.

Early dental implant failure
Definition: The implant doesn’t properly fuse with the bone (osseointegration), which means the implant is unstable and must be removed.

1)Infection at the implant site
An infection can develop during or after surgery. Risk factors for an infection include having an autoimmune disease, smoking, and bad oral hygiene.

2)Insufficient bone support/Poor Bone Quality or Quantity: If the jawbone is too soft or thin to support an implant, the healing process might not occur properly, leading to failure. This is why proper assessment and bone grafting (if needed) are essential before placing an implant.

3)Allergic reaction: You may develop a reaction if you’re allergic to titanium alloy

4)Failure to follow your doctor’s instructions
Your activities and habits have an impact, too. It’s imperative that you follow your surgeon’s post-surgery instructions to lower the risk of complications. You may be instructed to eat soft foods until the implant site heals, practice good oral hygiene, and avoid hard candy.
5)Poor placement: Incorrect positioning of the implant can affect its stability.

Late dental implant failure
1) Peri-implantitis is a pathological condition that occurs in the tissues surrounding dental implants, characterized by inflammation in the peri-implant connective tissue and progressive loss of supporting bone.
• Causes:
Similar to periodontitis, the primary cause is bacterial plaque and biofilm accumulation around the implant, leading to inflammation and tissue destruction.
2) Medical conditions
Dental implant failure is a possibility if you’re diagnosed with an autoimmune disease or conditions like rheumatoid arthritis and uncontrolled diabetes, which causes the body to heal at a slower pace. Slow healing can prevent osseointegration, where the implant fuses or integrates with your jaw bone.
3)Nerve or tissue damage may occur when a surgeon places an implant too close to a nerve.
4) A dental implant placed in the upper jaw may protrude into the sinus cavity.
5) Injury to the area surrounding a dental implant may loosen the implant, resulting in failure
6) poor oral hygiene: plaque deposition/calculus, food deposition.
