Summary:

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.

The "Hybrid Abutment": A New Design for Implant Cemented Restorations in the Esthetic Zones

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.

Surface Roughness of Restroation Margin Preparations: A Comparative Analysis of Finishing Techniques

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.

CAD/CAM Solutions for Minimally Invasive All-Ceramic Rehabilitation of Extended Erosive Lesions

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.

Ultimate Solution for Minimally Invasive Feldspathic Veneers
Full monolithic zirconia with external stain technique is one of the popular preference techniques used today. There are many selections of multi-layered zirconia disks and blocks available in the market, which enable dental technicians to produce faster and more esthetic results. When it comes to anterior fabrication, however, full monolithic is not always the best option to process the case. There are many varieties; unique translucencies and characterization that can be seen naturally, making it nearly impossible to achieve with just an external stain technique. That is to say, in order to achieve a natural and lifelike fabrication, a layering technique must be done. This lecture will speak about all ceramic layering technique with current technology of digital tools and how these technologies may be able to assist us.

Restoring the Pink and White Esthetics. Clinical Case Presentation
Every esthetic case is a challenge. As clinicians we need to understand and combine different treatment modalities and materials to achieve outstanding esthetic and functional results. This clinical case will demonstrate the importance of the little details, and how they influence the final result. We’ll go step by step thought the analyze, planning surgical and prosthetic procedures with focus on the key points that I find to be crucial.

Choosing Anterior Ceramics – The Concept of Restorative Volume - Part 1 of 2
In this lecture the author presents reviews significant literature and integrates it with clinical experience to select relevant factors that could provide a logical and practical guideline for restorative decisions in anterior teeth.The presented Concept of Restorative Volume is based on structural, optical, and periodontal factors. Each of these factors will influence the short and long-term behavior of restorations in terms of esthetics, biology, and function.

Interdisciplinary Team Dentistry for Total Dentofacial Esthetics - Part 2
Orthodontics sets up the foundation for future prosthetics in cases with periodontal, surgical and restorative dentistry requirements. Adult orthodontics simplifies complex clinical situations. Making it easier for restorative dentist to achieve better esthetic & functional results. Orthognatic surgery combined with orthodontics corrects skeletal discrepancies in order to have the patient ready for prosthodontic replacement of multiple missing teeth. Cases combined with implants to restore form & function will further illustrate the importance of multidisciplinary dentistry. Today´s practice requires a team approach that will be presented. In order to meet the patient´s demands for better esthetics and to obtain long term occlusal stability of our results.

Minimally Invasive Oral Rehabilitation... No More Crowns Please Premium Member Content

Minimally Invasive Oral Rehabilitation... No More Crowns Please
Many patients are in need of oral rehabilitation but cannot afford it, and we see them suffer and deteriorate feeling helpless. The traditional full mouth rehabilitation, is often excessive (it is extremely rare when a patient really needs a full mouth), and because is expensive, it is rarely accepted. Additionally most commonly crowns are used for rehabilitation, specially on patient with parafunctions. In this eye opening presentation, Dr. Ruiz demonstrates how adhesive dentistry breaks many of the rules we have been taught, as well as the importance of proper occlusal management.
