Restoration and Retention of Maxillary Anteriors with Severe Root Resorption
Background: The authors describe the treatment of three patients who had severe apical root resorption of maxillary lateral incisors caused hy ectopically erupting canines. Ectopically erupting canines derive from a normal path of eruption and may cause resorption of the adjacent teeth.

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.

Anterior Substructure Design Considerations for Lithium Disilicate Crowns
Considering anterior substructure designs for lithium disilicate crowns, a hybrid substructure design that supports a cusp to fossa anterior guidance relationships can increase the strength of the ceramic system without having to compromise the esthetic integrity of the crown. Refractive index values increase when the substructure thickens. Increasing the thickness of the substructure results in a crown of higher value.

Dental Ceramics: Material Properties and Clinical Applications Part 3 of 3
This presentation will give viewers a background of the physical and mechanical properties of current dental ceramics. The material properties of the ceramics will be used to explain clinical recommendations for selecting a restorative material and designing the prosthesis. Additionally, laboratory research data will be presented to help the clinician determine the best method to cement or bond an all-ceramic restoration. Finally, an overview of laboratory fabrication of all-ceramic restorations will be presented in order to show clinicians their options when sending out a laboratory prescription.

Multidisciplinary Esthetic Resolutions for Anterior Dentition: Integrating Science & Art
Not all patients can be treated the same; there are numerous methods and approaches we must consider before providing a service to our patients that include types of materials, surgery, minimally invasive restorative dentistry, prosthetics, etc. This lecture will take you through a decision tree of minimally invasive approaches to consider for multidisciplinary esthetic dentistry from a restorative and prosthetic point of view. Including a large emphasis on the science behind products and materials available in the market today.

Biologic and Surgical Strategies for Achieving Implant Esthetics – Part 2
Dr. André Saadoun describes delayed and staged implant placement.

Pure Dental Esthetics – From Titanium to Zirconia
The replacement of a single tooth with dental implants, especially when the patient has a high smile line, has been an esthetic challenge in implant dentistry. Typically, it requires very careful stages to create the final restoration as natural as possible. When there is loss of soft tissues, carefully made dental-gingival prosthesis becomes an alternative of therapy. For all cases with high smile line, achieving perfection in color and texture of the restoration it's not an easy task. Currently there are some ways to achieve better aesthetic results, including digital scanning of colors. This presentation describes step-by-step the application of a protocol developed in our clinic. Several cases will be discussed. In addition, recent technologies such as zirconium implants are also be discussed.

The Trial Smile Experience
Have you ever thought that if your patients only knew how much a smile makeover could enhance their faces, they would be interested in cosmetic dentistry? The Trial Smile Experience is an interactive exercise that demonstrates the facial improvement that your patients can expect to achieve, while building trust and eliminating their fear of the unknown. In addition, the model of the trial smile allows the clinician to communicate the esthetically driven aspects of the treatment plan to their technician and specialists. This tool is sure to create more cosmetic dentistry in your practice, and you will learn: • When the Trial Smile Experience is most effective • How to use digital photography for co-discovery with your patients • Techniques for performing an effective clinical mock up (trial smile) • How to use the mounted trial smile model and digital images to communicate with your technician and specialists

Diagnosing & Treatment Planning Gingival Esthetics
This program will look in depth at the concept of excessive gingival display and diagnosing the potential causes from vertical maxillary excess to altered passive eruption and super eruption following tooth wear.
