Summary:

The all-ceramic, full-coverage restoration has long been the center of the profession's ardent quest for the consummate esthetic restoration. Over the years, we have come to acknowledge the optimal esthetics of the all-porcelain crown, but its tendency to fracture over time rendered it an "alternative" restoration for specifically selected cases when compared to the "workhorse" of porcelain-fused-to-metal restorations. The initial dental feldspathic porcelains exhibited low shear strength with a definitive brittleness that readily fractured during function and poor marginal fidelity due to the poorly controlled sintering shrinkage. Early changes in composition tried to reinforce this material, utilizing a luminous materials and other additives such as leucite. While this still proved to be inadequate, an advantage from the addition of these products, particularly leucite, was to raise the coefficients of thermal expansion and the melting points to facilitate the bonding of the ceramic to a reinforced metal substructure. However, the all-ceramic restoration still provided vastly superior esthetic results due to its optical properties, beyond the inherent color of the ceramic, and compensation had to be made for the lack of light transmission and refraction over the stronger but opaque metal core.

CAD/CAM Solutions for Minimally Invasive All-Ceramic Rehabilitation of Extended Erosive Lesions
Dental erosion is a global health problem that can lead to significant functional and esthetic impairments of the affected patients. Treatment of sever cases with augmented loss of the vertical dimension of occlusion (VDO) represents a challenge for both the dental team and the patient. CAD/CAM technology was used in the presented case to analyze the inter-occlusal space. The case report documents a practical, digital approach and discusses the advantages related to treatment time, ease of treatment, and predictability.

Predictable Implant Aesthetics Utilizing A Custom Fabricated Provisional Abutment & Impression Coping
Mastering the art of predictable implant aesthetics can be challenging. One of the most stressful areas for most dentists is the process of creating a beautiful provisional that will guide tissue and predictably communicate the aesthetic outcome for the final restoration in the aesthetic zone. Combining the use of a custom fabricated provisional abutment, provisional restoration and a custom fabricated impression coping many of the aesthetics challenges can be addressed. This information can then be communicated to the laboratory to ensure the most predictable aesthetic outcome possible. This program is designed to simplify and streamline the entire process of implant provisionalization and impression. This program will provide a systematic, step by step approach to tissue management, provisionalization and impression of implant cases.
