UNLABELLED The fixed replacement of a single posterior missing tooth for those patients who cannot have either implants or conventional laboratory-generated fixed prostheses has always been a challenge to clinicians. The development of fiber-reinforced composites (FRCs) has opened up new possibilities of chairside treatment options to manage these types of clinical situations. Techniques using ...

conclusions the treatment reported for reattachment of the tooth fractures and post and core techniques are reasonably easy while providing immediate and lasting results in patients’ regaining of social confidence and functionality. introduction the fracture of front teeth is one of the routine presentations of traumatic injuries. the treatment of a fractured tooth involving the pulp includes r...

Patient demand for esthetic dentistry with minimally invasive procedures has resulted in the extensive use of freehand bonding of composite resin to anterior teeth. Preservation of remaining tooth structure and using as much enamel to bond to have made the procedure very predictable. In order to achieve maximum esthetics, the dentist must be able to use multiple layers of composite to mimic too...

Finite element analysis (FEA) was used to investigate the influence of different post systems on the stress distribution of weakened teeth under oblique-load application. A maxillary central incisor root obtained from a sound tooth was weakened by partial removal of dentin inside the root canal. Seven two-dimensional numerical models, one from the sound tooth and six from the weakened root rest...

merization of dental composite materials during lightcuring is a leading cause of adhesive restoration failure, resulting in postoperative sensitivity, marginal staining, and recurrent caries.1 This polymerization contraction shrinkage creates stresses as high as 13 MPa between the composite material and tooth interface2 (1 MPa = 145 psi). This stress can exceed the tensile strength of the enam...

The aim of the study was to determine the static load-bearing capacity of fractured incisal teeth restored with the conventional adhesive-composite technique or by using fiber reinforced composites (FRC). Upper incisal teeth were prepared by cutting the incisal part of the crown horizontally. Restorations were made by three techniques. Group A (control group) was restored by reattaching the ori...

Improper design involving the intaglio surfaces of the pontics can lead to food impaction, plaque accumulation and a subsequent severe inflammatory tissue response. Proper choice of pontic material and design is a crucial determinant ensuring clinical success of fixed partial dentures. This article elucidates restorative and comprehensive management of pontic induced hyperplastic gingival enlar...

introduction: the restoration of endodontically treated teeth is a topic that has been studied extensively but it is still a challenge for dental practitioners. the aim of this study was to evaluate fracture resistance, fracture patterns and fracture location of endodontically treated human maxillary premolars restored with direct and indirect composite resin and ceramic restoration. methods: e...
