Prosthetic complications in implant dentistry

Abstract

Rehabilitation with dental implants is a common practice to replace missing teeth. There are two options: screw-retained or cement-retained prostheses. However, these treatments can present prosthetic, biological and aesthetic complications. Single implants with ceramic crowns are a preferable alternative, avoiding tooth preparations, but facing the challenge of fractures. Multiple screw-retained dentures present a risk of ceramic chipping, especially with angled abutments. Implant-supported overdentures are less invasive but may have complications with O-rings and abutments. The choice between internal and external connections, with or without intermediaries, affects the prevalence of loosening, favoring international connections. The selection of the prosthetic crown depends on specific criteria, considering failures and complications of each type, cemented or screw retained. Therefore, the present work aims to report the nuances and complications associated with different approaches to implant prostheses to make informed clinical decisions.
