Finishing and polishing techniques: direct composite resin restorations.

Contemporary clinicians are responsible for delivering realistic restorations that closely resemble the existing natural tooth structures. In order to achieve such aesthetic results, the use of exemplary materials is required. Recent advancements in composite resin systems have improved the practitioner's ability to deliver optimal results using chairside techniques. The incorporation of a precise finishing and polishing protocol further allows the clinician to seal the restoration and maintain natural surface luster and contour. This article presents the necessary finishing and polishing protocol to ensure long-term aesthetic results.

[Computer-assisted occlusal finishing].

The finishing of a fixed appliance case is one of the greatest challenges in our specialty and is playing an ever-increasing role in treatment considerations as patients become more demanding. The quality of the finishing is, in fact, often seen as an indicator of the orthodontist's skills. The finishing of a lingual case is subject to exceptionally exacting requirements. This often leads not only to longer chair times towards the end of the treatment but to longer treatment times overall. The procedure described in this article permits high-quality finishing with no greater clinical resource input than with conventional labial appliances. Five essential factors are presented and discussed.

Composite tints: mixing composite materials to alter color and techniques to simulate hypocalcification and craze lines.

The purpose of this article is to teach advanced composite techniques based on sound material science and advanced artistic principles. The effects of oxygen inhibition, shrinkage, wear, filler content, and composite chemistry are reviewed. Color blending using composite translucency to show through underlying and surrounding tooth structure achieves improved color matching and color transition from tooth structure to a composite restoration. Mixing color tints modifies composite color, and applying composite tints produces effects such as hypocalcifications and craze lines.

Study on the effect of Y2O3 addition to the fluorescent property of dental porcelain.

The appearance of dental porcelains is comparable to natural teeth. This study discusses the effect of Y2O3 addition to the fluorescent property of dental porcelains. The composition of dental porcelains contained Y2O3 as the fluorescent agent and base frit. The combinations of Y2O3 added consist of a series with 0.5, 1.0, 1.5, 2.0 and 2.5 wt% respectively, based on the total composition. In the extreme condition, fluorescent agents are added from 5.0 up to 10.0 wt%. In order to enhance the fluorescent property of dental porcelains, an opacifiying agent, cerium oxide (CeO2) was also added to dental porcelains composition. The fluorescent property was determined using Spectroline EF-1400C/F that emits 240 nm wavelength ultraviolet light. The microstructure was examined by Scanning Electron Microscope (SEM). The result shows that, the fluorescent properties displayed are similar to natural teeth when subjected to ultraviolet light. SEM micrograph was able to show the fluorescent agent dispersed in glass phase. Increasing additions of Y2O3 gave the fluorescent properties near to natural teeth.

Achieving optimal aesthetics using contemporary porcelain materials: a case report.

While the selection of an appropriate material contributes to restorative success, a thorough treatment plan with enhanced clinician/technician communication is required to ensure an appropriate and aesthetic result. A concise understanding of the patient's existing condition, desires, and expectations is critical to ensure restorative success. This case presentation demonstrates the clinical and laboratory protocols for the development of predictable, functional, and aesthetic porcelain restorations in treating severely compromised maxillary anterior dentition.

Using the golden proportion in aesthetic treatment: a case report.

Many dental patients are unhappy with their smile but believe a beautiful smile is outside their budget. The first step is to listen to the patient in order to understand what his or her primary concerns are. The second step is to examine carefully and analyze the case to develop a treatment plan that will fulfill as much as possible of the patient's desires within the context of his or her constraints (financial or otherwise). Also, remember that dentistry doesn't end when the last veneer is placed or the last bill is paid. The final step is to maintain a strong relationship with your patients to ensure good oral hygiene and restorations that are as long-lasting as they are beautiful.
