Given the popularity of dental implants, determining their prognosis is an integral component of dental practice. An accurate prognosis is crucial to development of an appropriate treatment plan and may require alterations as overall status or the status of implants or natural teeth change. The importance of an established set of factors for determining implant prognosis would be highlighted in dentist-patient communication and in interdisciplinary collaboration. The main objective of the proposed prognostication system is short- and long-term success of dental implants. The aim of this study was to review evidence-based prognostic factors including surgical, peri-implant, prosthetic, and overall considerations in implant dentistry and to propose a new prognostication system. A blind survey was taken by 67 prosthodontists, periodontists, and oral surgeons at three dental schools to assess the importance of each consideration based on clinical experience and available evidence. The results supported incorporation of the comprehensive review of evidence-based prognostic factors into the proposed dynamic system for dental implant prognostication.
