Dental implant failure causes, treatment, and diagnosis: A literature review

Despite the high success rates and stability of dental implants, failures do occur. The most important etiological factors for early implant failure are surgical trauma together with bone volume and quality, while etiology of late failures is more controversial. Occlusal overload and peri-implantitis could be associated with late failures. Suboptimal implant design and improper prosthetics also play an important role in implant complications and failure. Early detection and treatment of initial progressive bone loss around dental implants by mechanical debridement with plastic/titanium/gold-plated instruments, antimicrobial therapy, and regenerative therapy are the keys for the revival of early failing implants. The aim of this paper is to describe different causes of failure in detail and treatment modalities to deal with dental implant failure.
