A Review of the Risk Factors Involved in the Late Failure of the Dental Implant

Dental implants are increasingly being used to replace missing or lost teeth. Despite significant advances in materials, techniques, and implant design, implant failure remains a major concern for both the dentist and the patient. The most common causes of implant failure are peri-implantitis and a lack of osseointegration. Other causes of implant failure include occlusal overloading, compromised or poor medical status of the patient, habits that harm oral tissues, and implant selection. The most pressing issue that all implantologists face today is the occurrence of complications and failures in implants. To further improve treatment outcomes, the etiologies and factors associated with implant failures should be identified. Osseointegrated dental implants have long been regarded as the closest substitute for missing teeth.
