How direct bonding satisfies an esthetic need.

The patient was more than satisfied with his appearance and with the cost of the procedure. After the wedding, he was ready to begin a more conventional series of treatments with orthodontia. Within the past several years, we have significantly progressed in our ability to provide complete in-office, long-term comprehensive dentistry. This article was written to help dentists visualize the potential of both materials and techniques for direct, in-mouth restorative dentistry. As more composites or composite replacement materials become available, practitioners will learn to perform direct-placement techniques even more skillfully. The majority of patients appear to covet white, bright teeth--sometimes to a degree that is beyond their normal color. This patient was no different. As a dentist, I have learned to give in to patients' demands. After all, it is their teeth.

Achieving and maintaining predictable implant esthetics through the maintenance of bone around dental implants.

The position of gingival soft tissues depends on the position and health of the underlying alveolar bone. Implant designs are evolving to maintain bone at predictable positions on the implant body through the development of stable and simplified prosthetic choices in abutment designs. The positioning of the restorative abutment deep inside the implant allows the abutment-implant joint to remain stable for a prolonged service life. With this stability, the titanium abutment allows the connective tissue and junctional epithelial seal ("biological width") to form and remain on the side of the abutment, rather than the side of the implant. Abutment joint stability plus well-defined implant surface topographies allow predictable implant rehabilitation in challenging situations. With the use of a mechanically and biologically stable joint interface, the prosthetic flexibility of a two-piece modular-style implant system allows the greatest flexibility for application in routine surgical and restorative implant dentistry.

Effect of the cavity configuration factor on the marginal microleakage of esthetic restorative materials.

PURPOSE: To evaluate the effect of the cavity configuration factor (CF) on the marginal microleakage of cervical restorations with four aesthetic restorative materials. MATERIALS AND METHODS: Conventional cavities, 2.9 mm in diameter and 1.5 mm deep, with CF=2.7 and "saucer"-shaped ones with CF=2 were created in 60 extracted premolars. The following groups were established: G1: Z100/Single Bond, G2: Freedom/Stae, G3: Vitremer/Primer and G4: Durafill/Durafill Bond, following each manufacturer's directions. Thermocycling of the specimens was performed in an aqueous solution of 2% buffered methylene blue, with the temperature varying between 5 to 55 degrees C, for a total of cycles of 60 minutes per day, for 7 days. The specimens were then sectioned and evaluated by two observers using photographs acquired from a stereomicroscope. The values were subjected to Kruskal-Wallis analysis and the Dunn and Wilcoxon test. RESULTS: The averages of the microleakage scores observed in the conventional and "saucer"-shaped cavities were respectively: G1: 0.66/0.46; G2: 0.92/0.69; G3: 1.8/1.86; G4: 3.54/2.3.
