Background Crown fracture is the most common type of fracture and frequently affects the anterior teeth. Crown fractures have been treated in several ways depending on the location and kind of fracture. This case emphasizes reattachment of fractured fragments using fiber-reinforced post. Also this case report underlines the related aesthetic concerns of reattaching of the fractured fragment. ...

Considering tooth crown engineering, three main parameters have to be taken into account: (1) the relationship between crown morphology and tooth functionality, (2) the growth of the organ, which is hardly compatible with the use of preformed scaffolds, and (3) the need for easily available nondental competent cell sources. In vitro reassociation experiments using either dental tissues or bone ...

OBJECTIVE To report the effects of a primary tooth trauma on the underlying permanent tooth germ. CLINICAL PRESENTATION AND INTERVENTION A 12-year-old girl was referred to our clinic with a complaint of poor aesthetic appearance. The crown of the permanent maxillary left central tooth exhibited an increased clinical crown height with an 'enamel hyperplasia' in the cervical third and had hypop...

Young patients are often frequently involved in traumatic dental injuries. The most common type fracture in permanent anterior teeth is a crown fracture. Direct restorative procedures using composite and fiber posts can be an esthetic and conservative approach in the case of extended fracture of an anterior root-filled tooth with little remaining coronal tooth structure. Currently, prefabricate...

OBJECTIVE The reattachment of the crown fragment to a fractured tooth is a conservative treatment that should be considered for young patients with crown-root fractures to the maxillary incisors if the subgingival fracture can be exposed to provide isolation. Gingivectomy, the surgical or orthodontic extrusion of the apical fragment is necessary to expose the subgingival fracture. This report d...

OBJECTIVES The aim of the investigation was to examine the forms of the crowns in the maxillary anterior tooth segment and corresponding gingival characteristics among healthy Taiwanese subjects. MATERIALS AND METHODS The crown width at the apical third (CW), length (CL), gingival angle (GA) and the interdental papilla height were assessed from the diagnostic stone model using a calibrated pe...

AIM The purpose of this case report is to describe the clinical procedure for fabricating fiber-reinforced composite (FRC) onlay composite resin restorations using a FRC as the substructure. BACKGROUND A variety of therapeutic modalities are available to restore teeth with moderate coronal defects in the posterior region of the mouth. For patients who refuse complete crown restorations or whe...

BACKGROUND Understanding mechanisms responsible for changes in tooth morphology in the course of evolution is an area of investigation common to both paleontology and developmental biology. Detailed analyses of molar tooth crown shape have shown frequent homoplasia in mammalian evolution, which requires accurate investigation of the evolutionary pathways provided by the fossil record. The neces...

Novel-design bonded porcelain restorations, the so-called Type IIIA BPRs, represent a reliable and effective procedure when restoring large parts of the coronal volume and length in the anterior dentition. While traditional treatment approaches involve the removal of large amounts of sound tooth substance (with adverse effects on the pulp, gingivae and crown biomechanics, as well as serious fin...
