Summary:

Clinicians have been diagnosing, treatment planning, placing, and restoring modern dental implants using periapical and panoramic imaging films to assess bone anatomy for several decades. Two-dimensional film images have been found to have limitations because of inherent distortion factors, and the non-interactive nature of film itself provides little information regarding bone density, bone width, or spatial proximity of vital structures. Digital radiography permits some interaction to enhance diagnostic interpretation but ultimately remains two dimensional (2-D). It was not until CT scan technology became available for dental applications that the three-dimensional (3-D) properties of the jawbones and vital structures became apparent. The advent of 3-D reconstruction using CT or cone beam CT (CBCT) empowers clinicians with tools to simulate implant placement, bone grafts, or orthognathic surgical procedures in a true and accurate virtual environment. There are three basic views that a CT scan will provide: panoramic, axial, and cross-sectional. The fourth view contains the 3-D reconstruction, and may differ in quality depending on the scanning machine and the software that is used to manage the CT data.

Soft Tissue Recession Around Implants 2
Implant therapy is a predictable method of replacing lost teeth and involves consideration of numerous surgical and restorative criteria. Part I of this article explained the behavior of the hard and soft tissue around the implant and reviewed various parameters that influence tissue remodeling. Part II emphasizes surgical factors (eg, tridimensional implant placement, platelet-rich fibrin, and the use of connective tissue grafts) and restorative factors as means of limiting soft tissue recession around implants.

The Bio-Derm Ridge Plumping Technique for Pontic Site Development
Seibert Class III apicocoronal and buccolingual alveolar ridge defects with associated gingival mucosal atrophy and absence of interdental papillae are common in edentulous areas within the anterior esthetic zone of the maxilla. Normal emergence profiles, critical to achieving esthetic restorations, require restoration of normal hard and soft tissue morphology, including re-establishment of adjacent interdental papillae.

Prosthetic Soft Tissue Development From Single to Full Arch Reconstruction
In addition to surgical intervention is the creation of the specific emergence profile that is essential in the aesthetic zone. The emergence profile composed of 2 parts, the abutment and the subgingival part of the crown. The shape of abutment can be individually shaped so that it gives natural appearance and varies individually (depending on the depth, angulation and diameter of the implant). Sometimes it even dictates the implant position. From a surgical perspective, soft tissue height, position and thickness need to be diagnosed and corrected when needed. From the prosthetic point of view, the emergence profile has to be created to mimic the natural appearance and maintained over time in respect to the biological changes. The course teaches step by step how to be successful with implant prosthetics from single tooth, partially edentulous to full arch reconstruction.

Bone Grafting & Implant Dentistry; Classification, Surgical Site Understanding & Membrane Selection Part 1 of 3
Once a tooth is extracted, the natural wound-healing cascade paired with irreversible alteration occurs. Hard tissue grafting techniques combined with the sound understanding of the surgical site theater will help the practitioner to make the proper decision in order to successfully treat their patient. The usage of biological modifiers and surgical barriers are proposed to assist in improving the predictability of the advance surgical care.
