I research Fig. 1_Example for different non- resorbable, titanium-mesh- reinforced ePTFE membranes, which are available in different forms and sizes depending on the manufacturer. Fig. 2_Close up clearly shows the titanium-mesh reinforcement in the non-resorbable membrane material. _Dental implantology has developed to a reli- able and successful clinical routine procedure for all thosecaseswhereanadequatebonematerialisavail- able. But this precondition is not always met. Never- theless, today also patients with a bone situation which is not optimal for implant insertion do wish an improvement of function and aesthetics—they actu- ally consider this to be granted. _Introduction Theuseofbarriermembranesfortheregeneration of bone defects has changed dental implantology in the course of the last 20 years a lot. The principle titled as “membrane-protected bone regeneration” was first described by Hurley et al. in 1959. Already in the 1960s, a research group around Bassett and Boyne tested and described micro porous cellulose acetatelaboratoryfilters(Millipore)forthetreatment of cortical defects on long bones and the osseous re- construction of the jaw. The basic idea of the authors wastousefiltermaterialfortheisolationofbonede- fectsagainstthecellsoftheadjacent,fibroussofttis- sue and to create an appropriate milieu for osteoge- nesis. However, these pioneering studies did not im- mediately lead to a broad clinical application of bar- rier membranes on patients. Actually, the clinical possibilities of the membrane technology were not recognised until the early 1980s where the research group around Karring and Nyman systematically in- vestigated the use of barrier membranes in different experimental and clinical studies on parodontal re- generation.
