Peri-implantitis is the main cause of late failure (5-15% after 10 years). Smokers have a three times higher risk of implant loss. Insufficient bone integration leads to early mobility (1-3% of cases). Overloading due to bruxism (teeth grinding) requires wearing a night guard. Poor cleaning causes bacterial infections around the implants. Technical complications such as screw fracture occur in 5-10% of cases. Systemic diseases (diabetes) increase the risk of failure. Annual professional cleaning halves the risk of complications. Early detection through X-ray monitoring can prevent failure. Revision surgery is possible, but costly and complex.
