Implant-supported conical crowns: Historical development and review of innovative systems
Rolf Vollmer, Martina Vollmer, Mazen Tamimi, Rainer Valentin, Germany
Using conical crowns on antirotational implant connections historically required the expensive fabrication of customized primary and secondary crowns. The Kobold system is a double-crown system using prefabricated components. It is suitable for immediate restoration using a splinted superstructure as well as for simple conical crown restorations on two or more implants or for extending existing restorations on natural abutments.

3-D Planning, Navigation, and additional Questions concerning practical Dentistry
Friedhelm Heinemann, Torsten Mundt, Manuel Pfeifer, Werner Götz, Christoph Bourauel, Reiner Biffar, Germany
It is the aim of this paper to reveal those patient cases where implantological prosthetic treatment with three-dimensional imaging by means of digital volume tomography (DVT) or computer tomography (CT) should be applied in order to analyze and eliminate errors. It is made clear that the increasing population with implants also requires an exact determination of the implant localization and diagnostic imaging of long term integrated implants.

Extraction and Immediate Implant Placement Using a Combined Hard and Soft Tissue Augmentation and Provisionalization Technique
Suheil M. Boutros, USA
Provisionalization of Endosseous implants at the time of placement has become more prominent in the field of dental implantology over the past several years, especially in the esthetic zone. The advantages of this modality of treatment include immediate tooth replacement, containment for bone grafting, soft tissue augmentation, formation and maintenance of esthetic soft tissue contours, minimizing the number of surgical procedures, the treatment time and an improved sense of the patient s perception of the implant treatment process. Although the survival rate for this technique is high and predictable, post treatment gingival recession and bone resorption in the aesthetic zone are potential limitations. This
case report presents a surgical technique for the preservation and augmentation of anterior aesthetics that combines minimally invasive extraction, immediate implant placement, a combined soft and hard tissue augmentation and immediate non-functional loading and the use of an implant system that allows platform switching to preserve the buccal bone...

The reconstruction of edentulous jaws aims first at augmenting the ridge width by gaining volume, and then at promoting growth of healthy and functional bone, able to support the prosthetic implant restoration over many years. The bone atrophy following tooth loss is due to a lack of mechanical stimulation and is emphasized by the pressure applied by the prosthesis and-in the posterior region-by the progressive pneumatization of the maxillary sinuses. The challenge of bone augmentation materials is to promote sufficient bone capital allowing adequate placement of implants. Nowadays, thanks to the recent breakthrough in understanding of cell metabolism, there is a great trend to develop synthetic materials for this purpose, in order to decrease the surgical trauma and the number of interventions. This is reflected by the number of products available on the market. PD Vitals Cement is a relatively new synthetic bone substitute that has been extensively studied in animal models. Although its use in clinical practice has shown positive results already, the histological data still needs to be developed and studied in details. The objective of this study is to evaluate the performance of PD Vitals Cement for the osseous regeneration of atrophic areas to allow subsequent placement of dental implants. Performance is assessed through clinical and radiological follow-up as well as histological examination to evaluate the osteogenic potential of the material in six patients. The selected indications for this study are the sinus floor elevation and the horizontal ridge augmentation, two procedures performed in two steps, allowing collection of cores when installing the implants....

Skin reaction around auricular implant abutment using different attachment mechanisms
Walid Sadig, Ziad Salameh, Saudi Arabia
With the advent of osseointegration in dental rehabilitation and recent advances in surgical and laboratory techniques, it has been possible to transfer and extend the osseointegration principle to facial rehabilitation.1 Retention, stability and aesthetics have been significantly improved with the use of endosseous implants, contributing to natural appearing prostheses...
