Biologic Considerations for Immediate Placement and Immediate Loading
Dr. Georgios Romanos presents the research and clinical data that has prompted the successful utilization of immediate implant placement and immediate loading in a variety of settings.

Managing Esthetic Implant Complications
Dental implant success today is judged not only by osseointegration but also by bone, tissue stability and of course long term esthetic results. Cosmetic predictability can often be difficult to attain, and esthetic implant failures can be multifactorial and patient management issues. Once esthetic implant failures occur, many cannot be fully corrected. Some complications must be addressed by an interdisciplinary dental team. In this summary of case reports, surgical considerations are provided, including cases of facial asymmetry/recession due to facial implant placement or bone loss resulting from technique/treatment failures, as well as papillary deficiencies. Restorative considerations for correcting failures are also discussed.

Bone Augmentation vs Short Implants: Making Clinical Decisions for Tooth Replacement at Sites with Alveolar Ridge Atrophy
There is often some degree of atrophy in sites planned for implant placement. An array of therapeutic options is available for implant placement in sites with vertical atrophy of the alveolar ridge, including ridge augmentation, sinus augmentation in the maxilla, nerve repositioning in the mandible and tilted implants. Short implants have been systematically evaluated as an alternative in sites with vertical alveolar ridge atrophy with favorable clinical outcomes comparable to standard-length implants. Decision making for selection of appropriate therapeutic modality for sites with vertical alveolar ridge atrophy has to consider many theoretical, surgical and prosthetic considerations. Surgical and prosthetic guidelines will be provided for application of short implants for posterior sites with limited vertical height.

Piezosurgery on Impacted Teeth
In the latest years, Oral surgery has strongly suffered of the technological innovations introduced in this field. In particular, the use of ultrasound applied to surgery has changed some of the most frequent clinical procedures, such as the extraction of third parties molars included, thus spreading an innovative concept in all dentistry: piezoelectric surgery or piezosurgery. So taking care of about 10 years of simple and complex extractive surgery I had the need to elaborate a lecture in which they are described in a simple and linear way the surgical techniques for the avulsion of the dental elements included, to provide a repeatable and predictable approach and method in order to reduce their invasiveness and traumaticity procedures

Complete Management of the Implant Site: From Simple Cases to Complex Situations
The health and the structure of the peri-implant tissue is vital for a long term prognosis of aesthetic and functional dental treatments. The prevalence of peri-implant diseases and recessions is a problem that must be overcome by a perfect treatment planning, along with a step-by-step design of the future restorations. When the clinician places an implant, he must consider the 3D positioning regarding the hard and soft tissue. When one decide to restore an implant, he must be aware of the gingival volume and it’s position. In this presentation, we want to show fully documented cases, from bone grafting, soft tissue enhancement, to final restorations.

Tissue Engineering and Platelet Derived Growth Factors: Evidence Based Therapy
Platelet derived growth factors are now routinely utilized in reconstructive therapy. This presentation describes very detailed and evidence based guidelines for clinicians interested in enhancing their abilities in tissue engineering, especially as it relates to bone augmentation. Specifically, while successful bone augmentation requires the standard surgical parameters of space maintenance, low pressure on the grafts and tension-free flap closure, optimization of this goal requires management and enhancement of the local biological conditions with growth factors. Towards that end, platelet concentrates through the constant release of growth factors are able to promote and enhance new vascularization, provide plasma protein, normal lipidemia, as well as increased collagen and fibrin activity.

Digital Workflow for Anterior Implant Aesthetics
We have seen excellent results in the aesthetic zone when immediate implant placement techniques have been used. A review of the current literature reveals and confirms the re-education of mid-buccal facial recession is best when an immediate provisional is used. If we can digitize this information and create a crown-root form matrix, we can allow tissue to maintain the exact 3D position of the crown and root of the tooth that is to be replaced. A technique using "dicom" files and "STL" files of the original tooth-root will be demonstrated. This will allow ideal healing of the surrounding hard and soft tissues in for any implants restoration.

Use of Stereolithographic Models as Diagnostic & Restorative Aids for Predictable Immediate Loading of Implants
Implant dentistry has evolved into one of the most predictable treatment alternatives in all of medical science. Advances in the surgical and prosthetic components, implant designs and surface technologies, and imaging techniques have allowed for significant modifications to occur with respect to one- and two-stage surgical protocols, accelerating treatment times to the benefit of patient and clinician. This article presents a technique to improve surgical and restorative accuracy, allowing for predictable placement and immediate loading of implants through use of CT imaging, stereolithographic models, and CT-derived surgical templates.

Effect of Different Cementation Techniques on Retained Excess Cement and Uniaxial Retention of the Implant-Supported Prosthesis
The aim of the study was to identify the different techniques of cementation (half filling, practice abutment, and venting) that will reduce the amount of retained cement and the effect of these techniques on retention of implant supported prostheses. The venting and practice abutment techniques are suitable methods of reducing retained excess cement with optimal retention values.

Treatment Planning 2000: An Esthetically Oriented Revision of the Original Implant Protocol
The purpose of this article is to outline the blueprint for a comprehensive multidisciplinary treatment philosophy, designed for developing the foundation for optimal esthetics in implant therapy. In addition, the important synergistic relation of the osseous, gingival, and restorative triad in creating the esthetic profile is described. The need to enhance the individual components of this triad is emphasized as the basis for a revised implant protocol actualized for treating the complex partially…
