28 I I user report _ bone augmentation implants1_2010 _Introduction The substitution of lost teeth by dental implants is being increasingly used to support prosthetic crowns or bridges. Many of these cases are associ- ated with bone loss that requires the filling of the defects by some kind of bone substitute. The recent improvements in synthetic bone materials have led to increased predictability and explain the ever-in- creasing use of such materials in various bone aug- mentation indications. Over the last years, one could observe a trend to bring products on the market that seem to be the next generation to supplement granular materials. Thesearethematerialsthathavetheirowncohesion and are presented in the form of a paste. Some ex- amples are easy-graft™ (Degradable Solutions, Schlieren, Switzerland), consisting of granules em- bedded in a sticky polymer matrix, Bond Bone™ (Augma Biomaterials, Karkur, Israel), a hardening calcium sulfate paste, Fortoss Vital (Biocomposites, Staffordshire,England),granulesembeddedinahy- droxylsulfatematrix,andPDVitalOsCement®(Pro- duits Dentaires, Vevey, Switzerland), a hardening calciumphosphate(brushite)cement.Wehavebeen workingwiththelattermaterialforacoupleofyears now. The large number of positive results obtained and the ease of use of the cement explain our great satisfaction with the product. Nevertheless, to get good results with this product requires to re-think the way of working because this material, like the pasty materials in general, cannot be placed the same way as one would place granules in a defect. The goal of this article is to exemplify the posi- tiveresultsobtainedwiththeVitalOscementintwo kinds of indications which seem to be the most ad- equate indications for the use of this product: im- mediate implantation and sinus lift in one-step.
