Summary:

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. Based on a virtual wax-up of the final restorations, CAD/CAM-fabricated preparation splints served as a guide and endured a most minimally invasive preparation design. Milled polymer provisional enabled the patient to visualize the final treatment outcome and served as a fracture-resistant temporary restoration to test the increased VDO. Monolithic lithium-disilicate ceramic, defect-oriented restorations with reduced ceramic thickness enabled a functional and reliable reconstruction of the severely compromised dentition. The case report documents a practical, digital approach and discusses the advantages related to treatment time, ease of treatment, and predictability.

Prosthetic Gingival Reconstruction in a Fixed Partial Restoration - Part 1: Introduction to Artificial Gingiva as an Alternative Therapy
The Class III defect environment entails a vertical and horizontal deficiency in the endentulous ridge. Often, bone and soft tissue surgical procedures fall short of achieving a natural esthetic result. Alternative surgical and restorative protocols for these types of prosthetic gingival restorations are presented in this three-part series, which highlights the diagnostic and treatment aspects as well as the lab and maintenance challenges involved.

The Key Role of the Provisional Restoration as a Blueprint in Esthetic Tx
Thru the direct Aesthetic Provisional Application technique, the provisional will serve as a preparation guide, aesthetic guide to both patient and lab as well as an occlusal guide. This gives the practitioner total control over the case, gives the patient a true visualization of what the permanent teeth will look like and gives the laboratory an accurate tooth position to be copied into final form. The d-APA is done with flowable compostite in the patient’s mouth thru a series of additions and reductions to the teeth to gain final position. Although challenging, the technique becomes very rewarding by placing artistry and control into the hands of the dentist.

Contemporary Bio-Materials and Combined Techniques for Esthetic Reconstruction
State-of-the-art technology offers conservative and esthetic alternatives to re-establish the shape and color of anterior teeth as well as the white and pink harmony. Tooth reduction for any restorative technique obliges us to be as conservative as possible. In this presentation we will share a short description of different material options developed in esthetic dentistry. We will present a case managed with a combination of techniques including: monolithic lithium-silicate ceramic veneers and cut-back/layering.

Minimally Invasive Restorations through Maximum Visualization Premium Member Content

Minimally Invasive Restorations through Maximum Visualization
This presentation will highlight providing minimally invasive restorations for patients, aided through technology such as magnification, illumination, percussion diagnostics and current dental material choices. Of critical importance today is the realization that patients are living longer and want to retain their teeth for a lifetime. With these factors in mind, the preservations of tooth structure is even more critical today than in former generations. For restoration longevity of minimally invasive restorations there must be a commitment to precision aided by magnification, understanding the physical properties of materials, controlling and managing the occlusal forces, learning how to measure and monitor the mechanical stability of tooth and implant stability with new technology breakthroughs and preventive control instructions.
