Immediate placement of Adjacent Implants in the aesthetic zone
The placement of a single implant is often used to demonstrate how it is possible to obtain a high degree of esthetics with dental implants. However the invaluable contribution of the adjacent natural teeth can never be ignored or underestimated. Supra-crestal fibres attached to the root cementum of juxtaposing teeth are entirely responsible for the maintenance of the tip of the interdental papillae which frames our implant-supported crown and helps to ensure an optimal esthetic outcome.
Placement of adjacent implants is much more problematic since it is widely recognised that in the absence of root cementum and supra-crestal fibres it is not possible to maintain a full length papilla and thereby not possible to frame our implant-supported crowns with an optimal gingival profile.
This presentation will consider how surgical technique, planning and timing of the placement of adjacent implants, as well as choice of component hardware can all contribute to achieving an optimal outcome with regard to both pink as well as white esthetics in the adjacent implant scenario.

Many advances have occurred over the last several years in surgical implant dentistry. It is essential for the practicing dentist to understand the science and clinical applications of procedures performed every day. Evidence for selection of graft materials and the reality of tissue engineering will be addressed, focusing on site development, sinus augmentation, and alveolar ridge augmentation. Since different alveolar ridge defects require a variety of surgical techniques and materials, we will review these issues. Here, clinical cases will be shown and presented with references to provide scientific basis for treatment protocols, along with some original research.

Recovering techniques for peri-implant soft tissue recession based on the MS Classification
Peri-Implant gingival recessions became a big complication for the aesthetic Implant treatments. For this time, the presenter wishes to present the classification of the gingival recession and relevant countermeasures.
Scientific rationale to optimize 3-dimensional site development
Presence of adequate bone volume to optimize ideal implant placement is a basic requirement for future successful and predictable results with osseointegrated implants. When patients do not have sufficient bone volume to receive appropriate implant length and diameter, augmentation procedures are indicated to alter compromised situations to ideal implant recipient sites. Numerous surgical procedures have been proposed and utilized to solve ridge deficiencies, however, selections of those depend not on evidence-based criteria but clinician’s own preferences and limited clinical experiences in most cases. In this presentation, current evidence-based guidelines of ridge augmentation are demonstrated to optimize site development.

Biological strategies for inter implant papilla
In the esthetic zone, best results can usually achieve using esthetic and biological guidelines of natural dentition and implant. But, we often have been esthetically poor results. Now, the some literatures have been necessary reported by utilizing the platform shifting implant, tissue sculpting of provionalization and CAD/CAM abutment and superstructures considered with the biological background.
So, we should be considered the following 3 major points.
1. Labial gingival level
2. Labial bone volume
3 .Interdental papilla
In this presentation, by analyzing my own clinical cases, the most appropriate surgical and prosthetic strategies will be demonstrated in order to recover and to maintain long-term stability for inter implant papilla.

Photofunctionalization of implant surfaces: A novel method to optimize implant-tissue compatibility
This lecture will discuss the scientific fundamentals of a chairside, rapid conditioning of dental implants via ultraviolet light (UV) immediately before use. This process, termed as photofunctionalization, induces marked physico-chemical changes of implant surfaces, which manifest biologically an enhanced strength of osseointegration and optimized bone-implant contact when compared to untreated implants. Photofunctionalization has been proven as effective and safe on any titanium-based implant surfaces or materials. Clinically, the speed of osseointegration evaluated by an increase in implant stability per month was 3 to >20 times greater in photofunctionalized implants. Pre-clinical and clinical studies revealed that quality and stability of periimplant marginal bone are improved around photofunctionalized implants. Clearly, the photofunctionalization is gaining a particular importance as it could have a significant impact on therapeutics using implant-related materials. In this context, the application spectrum of photofunctionalization is not only limited to implants, but also to implant abutments and titanium mesh. Although long-term studies are still needed, the current results suggest that photofunctionalization can enhance the outcome of implant therapy.

Sinus Floor Elevation Reconsidered
Current long-term statistical data reviews the dramatic change in implant failure patterns between the maxilla and mandible from 2002-2003. Two innovations have helped achieve more predictable results. First, it appears that implant surface design changes from a turned surface to a moderate rough surface (Dr. Jemt, 2014, AO Annual Meeting in Seattle) has been credited for the change in success / failure rates. Secondly, the past decade has seen modifications in surgical protocols, especially in the atrophic posterior maxilla. This presentation will review the transalveolar crestal approach (TAC) as a treatment option for sinus floor elevation and discuss potential influences of ISQ values to monitor the biological response of implant surface and connective tissues over ten years of clinical experiences in my clinic.
Consideration of the side-by-side implantation in the esthetic zone, by using the tunnel technique
The implant prostheses spread widely as the functional final restorations. And patients require esthetical result as well as functional result, especially in the anterior region demands esthetic result. However the characteristics of edentulous anterior region resulted in the thin bone architecture in the cross section. This thin bone architecture may result poor soft tissue support due to the minimal blood supply. Using the tunnel technique with ridge augmentation leads to rich blood supply, and may result the healthy soft tissue architecture surrounding anterior side –by- side implants.
The tissue biotype and labial tissue thickness are factors that may play a significant role, especially with regard to maintain the vertical soft tissue height. This presentation reports the relationship between ridge forms and crown contours.

Modified Transcrestal Sinus Floor Elevation Technique (Osteotome Surgical Technique) utilizing, biologics and CBCT.
Sinus floor elevation can be accomplished either through a lateral window technique or through a transcrestal sinus floor elevation technique. These sinus floor elevation has been a highly predictable surgical technique for increasing available bone height for implant placement in the deficient posterior maxilla. To achieve the optimum outcomes through a transcrestal sinus floor elevation technique, a number of strategies may be applied that have included modified osteotome surgical technique, graft-materials, biologics and CBCT. This modified osteotome surgical technique offer a minimally invasive and biologics shorten the time period of osseointegration. This presentation covers modified osteotome surgical technique utilizing biologics (EMD, PRP) and CBCT.

Immediate placement of implants into anterior extraction sockets: How far can we push the boundaries?
There is much controversy surrounding the immediate placement of implants into fresh extraction sockets, and what the parameters are in terms of where the limits lie. In this presentation, applying the current scientific literature to two clinical cases, the issues of fractured roots, adjacent missing/failing teeth, immediate placement, immediate restoration and implant stability, will be discussed, in order to demonstrate what can possibly be achievable in terms of functional and aesthetic success.
