Initial implant failures are due to the failure of initial osseointegration between the surface of the implant and surrounding bone due to a change in the treatment plan. The main causal factors are contamination, infection, peri-implantitis, trauma during or after surgery, inadequate healing and early burdening. The success of an implant procedure depends on many factors, but certain medical habits and conditions can increase the risk of an implant wobbling. Gum disease and bruxism (teeth grinding) can damage a healing implant, while diseases such as osteoporosis, which attack bone strength and density, can make it difficult to attach the implant screw.
Ongoing cancer treatment can also cause an implant to stop, as radiation therapy can sometimes inhibit the ability of bones to heal. Factors related to implant design can trigger early implant infection and cause implant failure. These factors include the use of non-biocompatible implant material or surface coating, contaminated implants, and an incorrect design of macroimplants or microimplants, which may hinder the stability of the primary implant. Smoking can increase the risk that the dental implant will fail, depending on where in the mouth the implant is placed.
This multi-stage procedure has a very high success rate, as 90 to 95% of implants last without problems for 15 years or more. During healing, we'll look at ways to reduce the risk factors that caused the implant to fail, such as stopping smoking or waiting for a cycle of cancer treatment to finish. Late implant failures are often the result of other health factors, as well as the pressure placed on the prosthetic tooth. It is imperative that your dental hygienist uses appropriate protocols, such as sterility, prevention of bone overheating, right flap design, stable insertion and placement of implants where there is enough bone.
Before receiving their dental implants, patients often ask if failure is a possibility, how often it can occur, and what is the likelihood of success in a second attempt in the event of a failure. Bone density and general bone health are an important consideration when it comes to implant dentistry. This may be due to the implant being placed in poor quality bone (i.e., in the back jaw) or in insufficient natural bone, or because the osteotomy is too large. Early failure can also occur when the immediate placement of the implant is performed at a site where there was a periapical pathology in the extracted tooth, or when an implant placed immediately and immediately provisioned is overloaded.
The reasons for dental implant failure include teeth grinding, an allergic reaction to the materials used, poor dental impressions, infections, nerve damage, implant movement, problems with the underlying jaws, and various medication-related conditions. Having a dental implant is more than just improving your smile, it can help prevent the many health problems associated with missing teeth. Froum, clinical professor at the DDS and director of clinical research in the Department of Periodontics and Implantology, New York University School of Dentistry, New York, New York; private practice, New York, New York. However, over the years, with the increase in the number of patients with dental implants, including some of my own, who have complications, doctors are more often faced with the question of why implants fail.
Similarly, Canullo and his co-workers13 demonstrated that a poorly positioned implant has a probability ratio of 48.2 (CI 11.4-204) of having peri-implantitis. Many factors can increase the risk of this happening, such as having certain medical conditions, an infection at the implant site (peri-implantitis), or complications from surgery. The crown of the dental implant (the false tooth) must match the surrounding teeth perfectly; there must be a perfect fit. .
