Fatigue Resistance and Crack Propensity of Novel "Super-Closed" Sandwich Composite Resin Restorations in Large MOD Defects
To asses the influence of conventional glass ionomer cement (GIC) vs resin-modified GIC (RMGIC) as a base material for novel, super-closed sandwich restorations (SCSR) and its effect on shrinkage-induced crack propensity and in vitro accelerated fatigue resistance. A standard MOD slot-type tooth preparation was applied to 30 extracted maxillary molars. A modified sandwich restoration was used, in which the enamel/dentin bonding agent was applied first, followed by a Ketac Molar or Fuji II LC base, leaving 2mm for composite resin material. Shrinkage induced enamel cracks were tracked with photography and transillumination. Samples were loaded until fracture or to a maximum of 185,000 cycles under isometric chewing, starting with a load of 200 N and gradually up to a maximum of 30,000 each...

Direct Posterior Bonded Restorations - An Outline of a Clinical Technique
In this study, the authors explore current concepts in direct posterior bonded restorations

Bringing Composite Resins to an Art Form in the Anterior Segment
Esthetic dentistry has evolved tremendously over the past twenty years and has gained unprecedented acceptance by both dentists and patients alike. Currently, the use of high-end technology and state-of-the-art materials enables specialists and general practitioners to perform esthetic procedures at the utmost level of scientific soundness while effecting like-life results.

Successful Composite Resin Restorations - Part 2 of 2
Amalgam has been a durable successful dental restorative material; however this material has recently come under question due to its mercury content and disposal. Composite resin materials range from flowable to highly filled condensable type viscosities. There are many factors that influence the success of posterior composite resin restorations. This presentation will identify the factors that limit success (size, patient type, caries risk, shrinkage, curing light) and the materials that can be successfully used to restore posterior teeth. Beginning with flowable materials and their clinical application the presentation will discuss the open sandwich technique, use of flowable posterior restorations, sectional matrices and fluoride, calcium and phosphate releasing materials.

Restorative Material Selection in Modern Prosthetics
The scope of restorative dentistry is changing at a rapid pace. Technological evolutions in optical scanning, 3D printing, milling and new age materials is in a revolution versus old world concepts. What to choose, why and then when makes the dental team and lab a critical part of the material selection team. What materials are the strongest, most durable and esthetic are key elements in this new world. This presentation will provide you an up to date review of the current materials available and the scientific literature to support specific guidelines as to the selection process. Zirconium, Lithium Disilicates, alumina etc. will be discussed as well as the correct cementation materials with these new products.

Principles of Clinically Successful Shade Taking - The Science & Art - Part 3
Dr. Ed McLaren demonstrates his actual clinical protocol for taking a shade on a patient requiring a single anterior crown.

Trouble-Free Highly Esthetic Composite Restorations
During this webinar we will discuss through pictures and HD videos, a methodological approach on how to consistently succeed highly esthetic trouble-free and durable composite restorations.

Preventing Subgingival Margins by Implementing Supra-gingival Dentistry Protocol
Restorative margins ending subgingival are considered “normal” and out of the control of the restorative dentist, but in reality subgingival margins are mostly avoidable and preventable! We have the technique and materials to be able to consider all of the above part of the history of dentistry.
