Simple Case Treatment Planning: Diastema Closure.
This article demonstrates the use of a smile evaluation form as an adjunct in arriving at diagnosis and developing a treatment plan for a patient desiring Diastema closure. It also shows the importance of the diagnostic wax-up for temporization and visualization of case outcome. The case also demonstrates the use of soft tissue lasers to create a gingival harmony that enhanced the resulting esthetics. Feldspathic porcelain was used for the final restorations because they provide optimal esthetics and translucency.

Esthetic Smile Design: Limited Orthodontic Therapy to Position Teeth for Minimally Invasive Veneer Preparation.
The standards of dentistry are being elevated, with a greater emphasis being placed on esthetics along with functionality. Minimally invasive dentistry has become an essential component in creating restorations that are functional and have increased longevity. In the case discussed in this article, the patient underwent 9 months of orthodontic therapy to correct her improper overbite and overjet, and the spacing of her dentition so the teeth could be positioned for future minimally invasive restorations. Orthodontic therapy was paramount in positioning the teeth so that the future restorations would have ideal axial inclinations and be as minimally invasive as possible.

A new, hybrid material for minimally invasive restorations in clinical use.
A new type of material consisting of a ceramic substructure infiltrated with a composite material--referred to as a hybrid ceramic--is currently being introduced for dental CAD/CAM use. The characteristic brittleness of ceramic is thus replaced by an elasticity resembling that of natural human dentin. The material features a high fracture load value of 2980 N, and is straightforward to process in CAD/CAM milling machines. This article presents a case example describing the manufacture of a veneer restoration.

Feldspathic veneers: what are their indications?
Many different materials and treatment options are available in esthetic and restorative dentistry. Various newer products, such as pressed ceramics, offer enhanced functionality; however, in thinner dimensions, they lack the inherent esthetic beauty of traditional materials such as feldspathic porcelain. As patient demands for better esthetics have increased in recent years, so too has the need for restorative materials that closely mimic the patient's natural dentition. Initially used for the creation of porcelain dentures, feldspathic porcelain has emerged as the premier esthetic material for custom veneer restorations. In recent years, the use of hand-layered powder/liquid feldspathic porcelain has been revived based on its highly esthetic values and little-to-no preparation requirements. By keeping preparation to a minimum, less tooth structure is lost and procedures are much less invasive, which is exactly what patients desire.

Low-risk dentistry using additive-only ("no-prep") porcelain veneers.
"No-prep" porcelain veneers have been effectively in use for more than two decades, and the bonding of porcelain to 100% enamel has enjoyed extraordinary success. Today's refined techniques, new and improved materials, and better training in emulating nature have enabled additive-only veneers to rival, or in some cases even exceed, the results of traditionally prepared veneers. In this case presentation, the author uses conservative, additive-only dentistry to enhance a young woman's smile by creating improved anterior esthetics.

Finite element stress analysis of diastema closure with ceramic laminate veneers.
The purpose of this study was to use finite element stress analysis to examine the relative importance of variables such as porcelain laminate veneer (PLV) extensions, loading angle, and loading level for the case of feldspathic ceramic veneering of teeth to manage diastema.. A 3D maxillary central incisor including its internal anatomy and morphology was constructed with ANSYS software for different extensions of PLV. Internal boundaries defining the dentinoenamel junction, the pulp-dentinal junction, the interface between the enamel-luting cement, and the porcelain-luting cement were well defined. The von Mises stresses distribution and stress intensity were analyzed on the free extension of PLV for varying extensions, various angulations (0 degrees , 30 degrees , and 60 degrees ) on the incisal edge, and for different loading levels (50, 150, and 250 N).. The numerical values of stress were recorded. A significant difference in stress was observed. Increased stresses occurred with increased extensions, angulations, and loading levels. At 0 degrees angulation, compressive stresses were visualized in finite element analysis for various magnitudes of force. Higher stress values of 182 MPa and 211 MPa were obtained for the 2.5-mm extension in the mesial surface and in both proximal surfaces for 0 degrees angulation at 250 N magnitude of force. The stress occurring at 30 degrees and 60 degrees angulations was the combination of compressive and tensile stress. Higher values of 261 MPa and 232 MPa were observed when forces were applied on the mesial extension of the PLV and on both the proximal surfaces for 2.5 mm at 30 degrees , 250 N magnitude of force. A maximum stress value of 507 MPa was observed when PLV were increased in mesial width by 2.5 mm for 60 degrees angulation at 250 N magnitude of force.. The extensions of PLV in diastema closure have more of an esthetic than functional consideration, but critical factors such as angulations and the loading level acting on the free extension of PLV are important.
