Evidence-based decision making: replacement of the single missing tooth

Single-tooth replacement may be effected through various methods, including the use of a resin-bonded fixed partial denture, a conventional fixed partial denture, and a single implant-supported crown. Although the introduction of newer therapeutic modalities, surgical and restorative techniques, and restorative materials has significantly expanded available treatment options, a greater demand is now placed on the diagnostic and treatment planning acumen of the clinician. The questions confronting each clinician are when to apply each treatment modality and how to use these therapeutic approaches to their maximum benefit for the patient. This article focuses on the factors that should be considered when making such clinical decisions and offers a framework within which to formulate appropriate treatment algorithms.
