Abstract

Restoration of primary teeth, severely destroyed by trauma or caries is a commonly faced problem in a pediatric dental clinic. In the past, the only option would have been to extract the affected teeth and replace them with prosthetic substitutes. Anterior tooth loss eventually leads to speech disturbances, development of parafunctional habits and psychological problems. Satisfactory restoration of these teeth, improving esthetics, along with the management of function has always been a challenge for pediatric dentist. An ever increasing demand for esthetics has led to innovation and development of newer treatment modalities for these problems. In an attempt to widen the treatment options as biologically and conservatively as possible, tooth structure is used as a restorative material to rehabilitate severely destroyed tooth crowns. This technique consists of bonding sterile dental fragments, obtained either from the patient or from a tooth bank, to the teeth. Such a technique was termed as 'biological restoration'. This article aims at reviewing the evolution, techniques and outcome of such biological restorations.
