N D Ruse, M J Sadoun
Advances in digital impression technology and manufacturing processes have led to a dramatic paradigm shift in dentistry and to the widespread use of computer-aided design/computer-aided manufacturing (CAD/CAM) in the fabrication of indirect dental restorations. Research and development in materials suitable for CAD/CAM applications are currently the most active field in dental materials. Two classes of materials are used in the production of CAD/CAM restorations: glass-ceramics/ceramics and resin composites...

OBJECTIVES: This work aims to review the key factors affecting the polymerization efficiency of light-activated resin-based composites. The different properties and methods used to evaluate polymerization efficiency will also be critically appraised with focus on the developments in dental photopolymer technology and how recent advances have attempted to improve the shortcomings of contemporary resin composites. METHODS: Apart from the classical literature on the subject, the review focused in particular on papers published since 2009...

OBJECTIVES: To provide a brief summary of the background theory of interfacial fracture mechanics and develop an analytical framework that identifies the critical factors for the analysis of the initiation and propagation of adhesion failure in composite restorations. METHODS: A conceptual framework utilizing interfacial fracture mechanics and Toya's solution for a partially delaminated circular inclusion in an elastic matrix, which can be applied (with caution) to approximate polymer curing induced cracking about composite resins for class 1 cavity restorations...

Composite dental restorations represent a unique class of biomaterials with severe restrictions on biocompatibility, curing behavior, esthetics, and ultimate material properties. These materials are presently limited by shrinkage and polymerization-induced shrinkage stress, limited toughness, the presence of unreacted monomer that remains following the polymerization, and several other factors. Fortunately, these materials have been the focus of a great deal of research in recent years with the goal of improving restoration performance by changing the initiation system, monomers, and fillers and their coupling agents, and by developing novel polymerization strategies...

Advancements in material research and adhesive technology have enabled the development of freehand bonding techniques that allow the preservation of remaining tooth structure and conservation of tooth structure during preparation-all while reinforcing the remaining tooth structure and improving the longevity and aesthetics of the restoration. In this article, the clinical concepts discussed were utilized with a recently developed composite resin material to restore the maxillary anterior dentition. Although the long-term benefits of this material remain to be determined, the utilization of this nanohybrid composite in this clinical presentation demonstrated an optimal functional and natural aesthetic result in the anterior region...

Restorative dentistry evolves with each development of new material and innovative technique. Selection of improved restorative materials that simulate the physical properties and other characteristics of natural teeth, in combination with restorative techniques such as the proximal adaptation and incremental layering, provide the framework that ensures the optimal development of an esthetic restoration. These advanced placement techniques offer benefits such as enhanced chromatic integration, polychromatism, ideal anatomical form and function, optimal proximal contact, improved marginal integrity and longer lasting directly placed composite restorations...

The rapid developments in biomaterials has led not only to improved materials but also to the development of clinical techniques made possible by these advances. Adhesive dentistry remains one of the fastest changing fields and this will most likely continue well into the next decade. Patients' aesthetic awareness and, to some extent, concern about amalgam has produced a growing demand for posterior tooth-coloured restorations. Originally this was met by ceramo-metal crowns and subsequently by the development of posterior composite resins...

In the search for an optimal treatment to restore the aesthetically prominent maxillary anterior dentition, new materials are continually introduced. The attention of the patients has shifted from function to aesthetics, biocompatibility of the materials utilized, and conservative preparation of teeth to be restored. To fulfill patient expectations, an advanced treatment modality has recently been developed. It combines porcelain with composite resin, thereby integrating the strength and resilience of composite resin with the aesthetic advantages of porcelain...

Efforts have been made during the last several years to develop polymer formulations that could replace ceramic materials for the restoration of occlusal surfaces. In most cases, resins have exhibited insufficient wear resistance, whereas the ceramic materials have had a history of excessively abrading whatever opposes them occlusally. Based on recent clinical information, it appears that major successes have been achieved in reaching the goal. The author discusses these advances and proposes a possible replacement for amalgam, based on new technology...

Discolouration and altered morphology of teeth are clinical problems commonly presented by patients seeking dental treatment. These patients usually complain of poor dental aesthetics, impaired speech as well as adverse psychological effect. Recent advances in the development of tooth-coloured materials, techniques in the application of these materials and treatment of tooth surfaces to accept and retain such materials have made it possible for the aforesaid dental conditions to be corrected by the process of bonding tooth-coloured materials to the teeth affected...

This article reviews the development, composition, chemistry, recent technological advances, and extent of use of composite resin restorative materials, adhesives, and pit and fissure sealants. The problems related to the clinical behavior of these materials in the oral environment are dealt with, and methods of minimizing their present deficiencies are suggested. Future directions that might be taken to improve these materials and solve some of the inadequacies that these materials exhibit are also discussed...

Research aimed at developing durable adhesion between esthetic restorative materials and tooth surfaces has been progressing for over 35 years. Inherent deficiencies in many esthetic materials have directed research toward new adhesive agents and modifications in application techniques. Overcoming these deficiencies has been difficult and many questions remain despite encouraging developments. A new generation of resin dentin-bonding agents has surfaced and may further adhesive efforts with modern composite resins...
