With the reestablishment of function no longer a clinical issue, the aesthetic challenge takes precedence, with patients expecting natural-looking results. Since the late 1980s, a leucite-reinforced pressed-glass ceramic (IPS Empress, Ivoclar Williams, Amherst, NY) has been utilized in the anterior region for full crowns and veneers and in the posterior region for crowns, inlays and onlays. This article presents results achieved with the IPS Empress all-ceramic system, which features a unique combination of strength and natural light transmission qualities that resemble the characteristics of natural teeth.

The proper fabrication of provisional restorations is integral to the overall success of restorative dentistry, as these templates are the initial architecture for the completed case. In a clinical setting, restorations may be utilized for an extended period, during which time the clinician and patient must feel confident. Due partially to a new generation of dental materials with unique properties, provisionalization can be predictably achieved. This article reviews the clinical criteria for the fabrication of interim restorations using a light cure/dual phase temporary crown and bridge material (Provipont DC, Ivoclar Vivadent, Amherst, NY) and its effect on the overall success of restorative procedures, including anterior and posterior restorations.

The introduction of restorative materials known as compomers is revolutionizing the field of restorative dentistry. This versatile material combines the most positive attributes of both glass ionomers and composite resins, such as continuous fluoride release, excellent adhesion, ease in placement, exceptional shade blending, and high polishability. This article examines the advantages of the compomer (Compoglass, Ivoclar Vivadent, Amherst, NY) in relation to those of other restorative materials, details the indications for its use, and provides a procedural analysis of its application through a comprehensive description of a case report.

With the continued increase in patient expectations for appearance-related restorations, the final result may be deficient in aesthetic qualities, such as color, contour, and shape. This is generally due to a breakdown in communication among the patient, dentist, and laboratory technician with regard to basic smile design principles prior to fabrication of the restoration. With the introduction of advanced porcelain systems (IPS Empress System, Ivoclar Williams, Amherst, NY), the clinician and technician can produce restorations that mimic the optical characteristics and color vitality of natural teeth. This article presents methods to improve communication, effectively evaluate smile design principles, and fabricate aesthetic all-ceramic restorations.

Although the benefits of pit and fissure sealants are widely recognized, many clinicians may not routinely include their application as part of a preventive oral health care regimen. This reticence may be due to lack of knowledge regarding technique, appropriate patient populations, and additional advantages to sealant use. This article reviews the background, properties and advantages of Helioseal F (Ivoclar Vivadent, Amherst, NY), which is a resin-based, light-curing, fluoride-releasing pit and fissure sealant. The author also provides a checklist of advantageous sealant properties and discusses sealant techniques and the patient profile of sealant candidates.

This article reviews a method for placement of full dentures in completely edentulous maxillary and mandibular arches. The selection of a maxillary central incisor is discussed along with the facial/tooth measurement, incisal papilla as a landmark in the maxilla, the midline, and the positioning of the remaining maxillary anterior teeth. The "S" position of the mandibular incisors, occlusion, and the verti-centric dimension are reviewed. The four basic tints of the denture bases are listed, and precision processing is recommended in fabricating the final dentures from information gained from the provisional restorations.

The ceramo-metal restoration still forms the backbone of modern restorative dentistry, despite many new systems. This article discusses a unique ceramo-metal system, its advantages, and clinical and technical applications teamwork between the dentist and the technician is emphasized. IPS Classic (Ivoclar Williams) is a ceramic system with several exclusive features. It encompasses Color Visions, a computer-generated shade system, and the IPS Impulse modifier system allows the ceramist unlimited creativity in color development.

Dr. Ronald Jackson is a graduate of West Virginia University School of Dentistry. After a general practice residency and service with the Navy in London, England, he began private practice in Middleburg, VA, in 1976. His practice emphasizes comprehensive restorative and cosmetic dentistry. In an effort to identify leaders in the field of restorative and cosmetic dentistry for Signature readers, I asked Dr. Jackson to meet with me to discuss his experience with inlays and onlays as well as his efforts to educate patients about the different types of restorations available to them. Dr. Jackson has published many articles and lectures extensively on esthetic inlays and onlays. He has twice been a featured speaker at the annual meeting of the American Academy of Cosmetic Dentistry and is scheduled to present at the 1995 meetings of the American Academy of Esthetic Dentistry and the American Society for Dental Aesthetics. Dr. Jackson is an accredited member of the AACD and holds visiting faculty appointments to the postgraduate programs in esthetic dentistry at the State University of New York at Buffalo and Baylor University Schools of Dentistry. He is on the editorial boards of three dental publications and consults to a number of dental manufacturers in the area of new product development and clinical testing of materials.

In developing improved dental materials and application techniques high standards and goals are set by the clinicians and the manufacturers. This article summarizes the prerequisites and desirable qualities required of composite resins for long-term process. A particular composite has demonstrated predictable and consistent long-term results and has established its place in quality dentistry. The applications for this composite resin are outlined in a clinical procedure. Its anterior/posterior universality is recognized. Several pre- and postoperative examples, in function for up to 12 years, are used to illustrate the results.

The ceramo-metal restoration still forms the backbone of modern restorative dentistry, despite many new systems. This article discusses a unique ceramo-metal system, its advantages, and clinical and technical applications; teamwork between the dentist and the technician is emphasized. IPS Classic (Ivoclar Williams) is a ceramic system with several exclusive features. It encompasses Color Visions, a computer-generated shade system, and the IPS Impulse modifier system allows the ceramist unlimited creativity in color development.
