research I lesion. The plastic and de-energised coverage often provestobedifficult(Tab.2).However,theclearroom stabilisation and the volume preservation (Fig. 3) are particularlytobehighlightedasthecoreadvantages. For the sake of completeness, I want to mention my use of a direct applicable GTR barrier for the cov- erage of periodontal bone defects—which is espe- cially indicated for an infestation of bifurcation—on theprotectionofaugmentationmaterial.Inthethen dental market, this barrier was available under the name Atrisorb® of the company Atrix Laboratories, Inc., Fort Collins, USA. Although the clinical healing processwasunremarkable,adimensionalstabilityof thisviscouslyappliedbarriermaterialsafterharden- ing was not traceable. At least, there was no disloca- tion of particles from the materials placed into the defect. Due to the few patients treated in this way, these were not included into the evaluation of the questionnaire.
