-Traumatic dental injuries (TDIs) are a serious public health problem. Epidemiology of dental trauma indicates that these injuries are more prevalent in child population of the world. Children are the sufferers in two-thirds of all TDIs observed. Although being a major fraction, crown-related fractures are a less severe form of TDIs with respect to their complications and sequelae. However, as with other types of traumatic injuries, the delay in seeking for immediate care following a traumatic injury and the lack of appropriate treatment may compromise long-term outcomes. This article reviews the occurrence, management, and prognosis of crown-related fractures in primary and permanent teeth in light of the recent literature.

“…Clinical procedures to lengthen crowns not meeting this requirement involve using build‐up materials to replace lost tissue2 or adding grooves or boxes in the tooth 1. Alternatively, the amount of remaining tooth accessible for preparation can be improved by moving the tooth orthodontically3, 4 or repositioning the tissues surgically,5 a technique which is among the most commonly performed surgeries in general dental practices 6…”

Effects of geometry on fracture initiation and propagation in all‐ceramic crowns

et al. 2008

The complex and patient-unique geometry of posterior all-ceramic dental crowns represents a particularly interesting set of challenges to understanding stress concentration and fracture evolution in response to loading. A series of numerical and physical experiments, with both single cycle and fatigue loading, show that geometry profoundly influences the stress concentration and fracture initiation and propagation. In stylized crowns with uniform axial wall height, stresses concentrate beneath the indenter. As the height of the axial wall increases, loads to cause failure increase linearly. In crowns with variation in axial wall height around the periphery, stresses concentrate both beneath the indenter and at the margin of the core ceramic. The magnitude of the stress concentration at the margin is directly related to the amount of variation in axial wall height around the periphery of the crown. Anatomically correct veneered zirconia core crowns subjected to single-cycle loads, fracture in areas of greatest stress concentration identified by finite element models. Fractures and stress concentrations that occur in response to single-cycle loading are important indicators of initiation sites for fatigue failure. (c) 2008 Wiley Periodicals, Inc.

Several techniques have been proposed for clinical crown lengthening procedures. Crown lengthening in esthetic zone can be classified in two basic types: Restorative and non-restorative cases after the crown lengthening is executed.Atraumatic surgical extrusion using a specially designed instrument called periotome was performed in four cases on isolated teeth in esthetic zone.The technique presented is an alternative approach to periodontal surgical procedures consisting orthodontic extrusion and osseous recontouring. It does not result in functional or esthetic deformities especially in the anterior esthetic zone.
