Post and core followed by crown is a common treatment option to restore the form, function, and esthetics of an endodontically treated tooth. Although uncommon, it is possible that patients may present with fractured core during the crown cementation appointment due to various reasons, including trauma and composite debonding. Depending on the extent and severity of the fracture, retrofitting the crown on a fractured core can be a preferred option. This technique describes the fabrication of vacuum-formed thermoplastic template adapted on an elastomeric putty index obtained from the inner aspect of the crown to build back the composite resin core in original shape. This technique is simple to perform, and the additional time and cost of preparing new crown can be avoided. Clinical Relevance to Interdisciplinary Dentistry This technique demonstrated the preparation of a vacuum-formed thermoplastic template adapted to the polyvinyl siloxane putty index obtained from the inner aspect of the crown. The technique facilitated chairside repair of the fractured core, thus the additional time and cost of preparing a new crown can be avoided. The effect of the temperature onto the flexible putty during the adaptation of the thermoforming sheet needs to be carefully evaluated.
