Causes of Dental Implant Failure

Dental implants are often the first choice for replacing missing teeth. Implants work by fusing to the jawbone, allowing them to support artificial teeth. While most people have success with dental implants, they do occasionally fail. Let’s look at why dental implants sometimes fail and what you can do to avoid this.

Failed Osseointegration

Osseointegration is the process of the implant fusing to the bone. When this process occurs, the implant becomes a permanent part of the bone, acting as an anchor for the artificial teeth. Implant failure can occur if the osseointegration process does not occur. This failure has a higher risk of occurring if you have uncontrolled diabetes, low bone density, or untreated gum disease. Poor oral hygiene can also impede the osteointegration process, so it’s critical to take proper care of your teeth, gums, and implants.

Failing to Follow Post-Operative Instructions

When you get your dental implants, your oral surgeon will provide you with a list of post-operative instructions that must be followed. You will need to take antibiotics to prevent infection and eat soft foods until further instructed. Failing to take the antibiotics could lead to an infection that causes the implants to fail. Also, if you eat hard foods too soon, your implants can become unstable and move or fracture. The oral surgeon would then need to remove the implants.

Nerve and Tissue Damage During Implant Placement

Oral surgeons must be careful when placing dental implants. Skilled oral surgeons use drilling techniques that protect the tissue and are careful when placing the implants, so they are not too close to any nerves. If you use an inexperienced oral surgeon, he or she might damage the nerves or soft tissue, causing pain, numbness, and even implant failure.

Occlusal (Bite) Overload

Excessive force is another situation that can cause implants to fail. The extra force can cause bone loss around the implants, making them unstable. This can also cause crowns to break and implants to fracture. If you clench or grind your teeth, then you’re at risk for occlusal overload. To help reduce the stress put on your implants, you can wear a night guard when sleeping.

Inflammation and Infection Around the Implants

Soft tissue and bone support the implants, allowing them to function as the roots of the teeth. Peri-implantitis is a chronic infection that causes gum and bone inflammation, leading to bone loss. Poor oral hygiene, osteoporosis, a history of periodontal disease, and smoking make people more likely to develop peri-implantitis. It is critical to visit the dentist at the first sign of swollen gums to treat the condition before it destroys the bone.

Implant Rejection

Implant rejection, whether early or late, is uncommon, but possible. You are at risk for early implant rejection if you have an extreme sensitivity to foreign objects or experience an allergic reaction to the implant. While poor oral hygiene, trauma to the implant site, and smoking can cause late implant rejection.
