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.

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....
