The increased risk of biomechanical issues with implants, components, and prostheses is a result of implant malposition. The bending moment acting on the implant restoration is created or amplified by the displacement of the implant axis from the imposed functional load. The effects of this can take many different forms, and they can include biological, mechanical, and aesthetic issues as well as implant failure. Dental implant restorations have a high success rate, but to reduce difficulties, they need to be carefully planned and managed. The most frequent reasons for the restorative and mechanical failure of dental implants are covered in this article, along with possible preventative measures.
