“Cell-to-Cell Communication: Guided Bone Regeneration” is a masterful animation movie from Quintessence Publishing Group. Geistlich Biomaterials supported the production and now offers an exclusive short version.

Invisible to the human eye, Guided Bone Regeneration takes place in the microcosm of the cells. What tasks are performed by osteoblasts, osteoclasts, pericytes, thrombocytes, fibroblasts and all the other cells? How do they communicate among themselves?


A recently published study with 10 yrs of data shows that autologous bone blocks resorb only minimally if they are protected by a slowly resorbing bone substitute and a collagen membrane.1

Bone blocks harvested from the retromolar region or the chin are the gold standard for the regeneration of large horizontal bone atrophies. The advantages: mechanical stability and the ability to stimulate new bone formation. Major disadvantages, however, are donor site morbidity and the marked resorption of the graft in situ. The literature describes resorption rates between 18 and 60 percent.2-8


The next EAO congress will be taking place from 29 September to 1 October 2016, this time in Paris. Stability, inflamed extraction sockets and peri-implantitis will each be headlining the Geistlich symposium and Geistlich hands-on workshops.

Stability is key to achieving successful outcomes in bone and soft tissue regeneration. But how to achieve stability? How can biomaterials contribute to a stable environment? Prof. Ronald Jung, Switzerland, will answer these key questions in the Geistlich symposium at the EAO congress on Thursday morning. 

Prof. Frank Schwarz, Germany, is going to tackle another key topic in both his symposium lecture and his practical workshop: peri-implantitis. Where are the limitations of non-surgical therapy? How is advanced peri-implantitis to be treated?


Le thème central de ce numéro est sans conteste l’augmentation osseuse.


Daniel Buser y expose ses résultats à long terme pour les augmentations latérales et Matteo Chiapasco présente la combinaison idéale d’os et de biomatériaux pour différents types d’augmentations.  

L’avenir de la régénération osseuse guidée est présentée par Christer Dahlin et Reinhart Gruber nous donne un aperçu du rôle des vaisseaux sanguins dans la régénération.

Enfin Paul Buxton, à la tête d’une équipe de recherche au sein de Geistlich Pharma AG, nous explique comment la connaissance et la compréhension des cellules intervenant dans la régénération permettent le développement de nouveaux produits.
