This case report demonstrates sequential periodontic, orthodontic and prosthodontic treatment modalities to save and restore deep horizontally fractured maxillary central incisor. The location of fracture was deep in the mucosa which reveals less than 2 mm of tooth structure to receive the crown. The procedures like surgical crown lengthening, endodontic post placement, orthodontic forced erupt...
STATEMENT OF PROBLEM Dentin and core materials that substitute for missing dentin are dissimilar materials. A core material with a lower elastic modulus may deform more under applied stress and therefore result in reduced stress concentration at the core/dentin junction. PURPOSE This in vitro study examined the effect of core stiffness on the fracture resistance and failure characteristics of...
AIM The aim of this study was to evaluate the fracture resistance of various provisional crown materials using an in vitro model test system. METHODS AND MATERIALS In the present study polycarbonate crowns, prefabricated by the manufacturer (3M Polycarbonate Crown), and the temporary crowns, fabricated in the dental laboratory environment, were fabricated using bis-acryl composite (Protemp II...
Two possible causes of crown dilaceration are trauma and developmental disturbances, and it has also been proposed that it might be associated with some developmental syndromes. This article details the diagnosis and describes the alterations in endodontic treatment procedures while managing crown dilaceration in maxillary central incisor. Diagnosis, endodontic access cavity preparation, root c...
Trauma may result in craze lines on the enamel surface, one or more fractured cusps of posterior teeth, cracked tooth syndrome, splitting of posterior teeth, and vertical fracture of root. Out of these, management of some fractures is of great challenge and such teeth are generally recommended for extraction. Literature search reveals attempts to manage such fractures by full cast crown, orthod...
This study investigated the effect of a crown-lengthening ferrule on the fracture resistance of endodontically-treated teeth restored with two dowel-core systems. Thirty-two extracted mandibular first premolars were sectioned perpendicular to the long axis at a point 1.0 mm occlusal to the buccal cementoenamel junction. Following endodontic treatment, the teeth were randomly assigned to four gr...
OBJECTIVE To review the literature searching for a consensus for the choice of orthodontic extrusion as treatment for crown-root fracture. MATERIALS AND METHODS An electronic search was performed in the databases PubMed, Cochrane Central Register of Controlled Trials and Scopus and a manual search of the Journal Dental Traumatology. RESULTS Forty articles were found in PubMed and 38 in Scop...
objectives: fracture strength is an important factor influencing the clinical long-term success of implant-supported prostheses especially in high stress situations like excessive crown height space (chs). the purpose of this study was to compare the fracture strength of implant-supported fixed partial dentures (fpds) with excessive crown height, fabricated from three different materials. mater...
Restoration of crown-root fractures with the involvement supracrestal attached tissues represents difficulties for clinicians, as these types require a multidisciplinary approach adequate treatment and successful prognosis. Depending on location fracture, different approaches, such periodontal crown lengthening procedures, rapid orthodontic or surgical root extrusion tooth extraction followed b...
