Knowledge regarding the types of complications that can occur with the dental procedures is an important aspect of treatment planning, dentist patient communication and post treatment care. Because the design of clinical implant studies has not been standardized the reporting of clinical complications tends to vary. Implant success and failure are dynamic time-linked conditions, and require periodic reevaluation and, if needed, a salvation treatment. Implant failure is a static end-result condition that requires removal of a failed implant.
