Updating Classifications of Ceramic Dental Materials
The indications for and composition of today’s dental ceramic materials serve as the basis for determining the appropriate class of ceramics to use for a given case. By understanding the classifications, composition, and characteristics of the latest all-ceramic materials, which are presented in this article in order of most to least conservative, dentists and laboratory technicians can best determine the ideal material for a given treatment.

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.

Retrospective Analysis of 26 Complete-Arch Implant-Supported Monolithic Zirconia Prostheses with Feldspathic Porcelain Veneering Limited to the Facial Surface
The purpose of this retrospective study was to evaluate the clinical performances of 26 implant-supported, complete-arch, monolithic zirconia restorations with facial feldspathic porcelain veneers for the rehabilitation of completely edentulous patients. Eighteen patients were treated with a total of 26 complete-arch fixed prostheses. The mean follow-up time was 20.9 months. In total, 154 implants were placed supporting 309 retainers and pontics. The results of this retrospective evaluation showed that monolithic zirconia restorations with facial porcelain veneer provided satisfactory clinical performance and suggest that these rehabilitations are a viable treatment option for completely edentulous patients.

The "Hybrid Abutment": A New Design for Implant Cemented Restorations in the Esthetic Zones
Cemented implant restorations are widely used by many dentists. The traditional abutment design resembles a natural tooth prepared for a crown with a similar taper and a chamfer finish line. A frequent complication associated with implant restorations in the esthetic zones is the recession of buccal gingiva over time. Abutment morphology, among several other prosthetic factors, may play an important role in the stability of gingival margin in esthetically sensitive areas, but this has never been thoroughly analyzed. With many considerations in mind and recent techniques released, this article proposes the "hybrid abutment: design (HAD), a new design that includes a combination of the two types of features - a feather edge on the buccal side, and a chamfer finish line on the lingual side. This article also presents a rationale for the use of different abutment designs for different situations.

Finding Z: A Mathematical Method For Predicting Tissue Position After Implant Abutment-Restoration Placement
A visible abutment-restorative interface is a problematic consequence, especially in the esthetic zone. This article presents formulas to predict the vertical tissue position around the abutment-restoration, which can be used both as a guide to the clinical situation and as an aid to computer-aided design and computer-aided manufacturing design.

Consecutive Case Series of Monolithic and Minimally Veneered Zirconia Restorations on Teeth and Implants: Up to 68 Months
The aim of this study was to evaluate the performance of monolithic zirconia in function and minimally veneered zirconia (feldspathic ceramic, not in function, on then facial surface to enhance tooth esthetics or replace gingival structures) on both teeth and implants. The restoration parameters monitored in the patient base were fracture, cracking, or chipping of the zirconia structure and/or the minimally veneered feldspathic ceramic. There were no observed complications with respect to these parameters associated with any of the restorations included in this study.

Surface Roughness of Restroation Margin Preparations: A Comparative Analysis of Finishing Techniques
This study compared the margin profile and surface roughness created by the tips of four different finishing instruments: fine diamond, dura white stone, tungsten carbide, and ultrasonic diamond-coated tips (UDTs). The aim was to determine which of these instruments produced the smoothest finish and created the most evenly contoured margin characteristics. It was hypothesized that UDTs would produce a rougher dentin surface than a fine diamond bur, that a tungsten carbide bur would provide a smoother finish than a fine diamond, and that the dura white stone would produce an intermediate finish.

Reconstruccion Protesica Gingival
La apariencia saludable del tejido circundante y su arquitectura son componentes esenciales para lograr la estética dental. Para crear el efecto de DENTICION NATURAL, es indispensable que el tejido gingival, se vea similar al de los de los dientes circundantes. La cirugía periodontal, siempre y cuando sea predecible es y ha sido un tratamiento de elección, previo a la colocación de la prótesis definitiva. Pero en algunos casos la cirugía es imposible o indeseable. La utilización de la CERAMICA ROSADA, es una solución para defectos gingivales, no solo donde la cirugía gingival no es posible, sino como un tratamiento opcional no quirúrgico o como primera opción.

Clinical Performance of Porcelain Laminate Veneers: Outcomes of the Aesthetic Pre-evaluative Temporary (APT) Technique
The article evaluates the long-term clinical performance of porcelain laminate veneers bonded to teeth prepared with the use of an additive mock-up and aesthetic pre-evaluative temporary (APT) technique over a 12-year period. Sixty-six patients were restored with 580 porcelain lamintate veneers. Over 12 years, 42 laminate veneers failed, but when the preparations were limited to the enamel, the failure rate resulting from debonding and microleakage decreased to 0%. Porcelain laminate veneers presented a successful clinical performance in terms of marginal adaptation, discoloration, gingival recession, secondary caries, postoperative sensitivity, and satisfaction with restoration shade at the end of 12 years. The APT technique facilitated diagnosis, communication and preparation providing predictability for the restorative treatment. Limiting the preparation depth to the enamel surface significantly increases the performance of porcelain laminate veneers.
