The ability to develop a reliable bond between a ceramic restoration and the tooth is a key element in the clinical success with CAD/CAM direct ceramic restorations. Composite resin luting agents are currently the preferred material of choice for adhesively bonding ceramic restorations. They provide several advantages, such as a durable and strong bond to the tooth and ceramic, good color match...

STATEMENT OF PROBLEM Little information exists regarding the outcome of crown build-ups on endodontically treated teeth restored with metal-ceramic crowns or with only a direct-placed composite. PURPOSE The aim of this study was to evaluate the clinical success rate of endodontically treated premolars restored with fiber posts and direct composite restorations and compare that treatment with ...

QDT 2005 1 he restoration of missing or compromised tooth structure requires dental materials that offer toothlike esthetics, functionality, biocompatibility, and longevity. Silica-based ceramics (eg, feldspathic porcelain) offer all of these necessities and are the materials of choice for esthetic all-ceramic restorations (eg, laminate veneers, ceramic inlays and onlays, and full-coverage jack...

The teaching activity of training of the students has a decisive role in the medical activities developing a competitive future for the dental practitioner. The modern restorative dentistry is developing the natural in all aspects, integrating the substitute, the flawless into the dental somato facial equilibrium. These issues are analyzed in terms of options for aspects of classic or modern me...

Metal–ceramic systems represent a high-strength treatment associated with long-term success, but they have several disadvantages, mainly in terms of esthetics and biocompatibility. Over the past decade, a number of novel all-ceramic crown and bridge systems have been developed, with the capability of restoring anterior, posterior and multiple units. The search for new methods has been driven, i...

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. MATE...

STATEMENT OF PROBLEM Computer-aided design and computer-aided manufacturing (CAD/CAM) generated restorations are gaining popularity. However, limited clinical evidence is available for single-unit posterior CAD/CAM restorations fabricated with established and newer crown materials. PURPOSE The purpose of this clinical study was to assess the restoration quality of and gingival response to CAD...

STATEMENT OF THE PROBLEM The success of metal- ceramic- restorations (MCR) depends on the presence of strong bond between porcelain and metal substructure. PURPOSE The purpose of this study was to evaluate the effect of hot pressing technique on the bond strength of a metal-porcelain composite in comparison to layering technique. MATERIALS AND METHOD Thirty Nickel-Chromium specimens were pr...

The marginal fit is one of the most important criteria for long-term success of all-ceramic restorations.[1] When considered clinically, a casting becomes acceptable only when the marginal gap between the prepared tooth and the casting is indiscernible both visually and also while probing. The marginal gap may lead to increased retention of plaque. This changes the distribution of microflora as...

Digitalization has become part and parcel of contemporary prosthodontics with the probability of most of the procedures being based on the digital techniques in the near future. This digital revolution started in the latter half of the 20th century by converting analog objects/signals into digital bits and bytes. Recent developments in all-ceramic materials and systems of computer-aided designi...
