Abstract [en]

The primary choice for initial restoratioon of a crown-fractured front tooth has for long time been resin composite material. The restoration can in most cases be performed immediately after injury if there is no sign of periodontal injury and the tooth responds to a sensibility test. The method´s adhesive charater is conservative to toothstructure and with minimal risk of pulpal complication. In addition it offers an esthetic solution to the patient immediately after an injury, which may bring a little joy in a sad situation. The resin composite build-up is often changed or repaired couple of times, before the tooth is resored with a porcelain or porcelain fused to metal crown, at a time when the pulp is out of danger for more invasive preparation. In some cases an endodontictretment is still necessary. After crown therapy a gingival inflammation may occer due to the usual sub-gingival preparations. Afer some years in situ, the crowns may present an esthetic problem due to exposure of un-esthetic crown-margins. The invasive permanent crown restorations are thefore often not sucessful on a longterm scale. On other hand a conservativedirect restoration of an extensively fractured incisor crown with composite may be an exceedingly demanding procedure, involing esthetic acceptability, function and biological aspects and require significant skills, which may influence durability. When are we ready to consider the non-invasive resin composite crown build-up as a permanent restoration? Has its durability improved? Do today´s materials and techniques result in a better prognosis? Where are the problems? In this chapter these matters will be discussed with focus on factors in clinical procedures, which can influence the longevity of the restoration.
