Uneventful open-healing using resorbable collagen membranes

The survival rate of implants placed immediately into extraction sockets with bone and soft tissue regeneration in an “open-healing” technique was 100% after 4 years in function.1

Essential protection from long-term complications
Ass. Prof. Stefan Fickl | Germany

For long time, soft tissue management was seen as purely esthetic. But around implants both keratinized tissue and sufficiently thick soft tissue have protective functions.

Bisphosphonates as contraindication for augmentations?
Prof. Bilal Al-Nawas | Germany

Not all patients on anti-resorptive therapy have a high risk of osteonecrosis of the jaw. When is implantation possible, and what should a dentist consider?

Geistlich Bio-Oss® and Geistlich Bio-Gide® in combination with orthodontic tooth movement

Do tooth movement modalities have an impact on the intrinsic healing pattern of intrabony defects treated with Geistlich Bio-Oss® and Geistlich Bio-Gide®? A preliminary histological evaluation gives the first answers.1

“Most patients like the idea of getting a customized solution”
Verena Vermeulen | Switzerland, Dr. Luis Marcelo Calderero | Switzerland

Bone block or GBR? Form-stable membrane or customized titanium scaffold? We discussed vertical ridge augmentation treatment options with two experts: Dr. Isabella Rocchietta, London/ United Kingdom and Prof. Bilal Al-Nawas, Mainz/Germany.

“This technique reduces the difficulties to less than half”
Enea Simonato | Italy, Verena Vermeulen | Switzerland

Many, many techniques are available to gain vertical bone height—including meshes, non-resorbable membranes, bone blocks or osteotomies. Prof. Matteo Chiapasco, Italy, has successfully used most of them. Why did he switch to Yxoss CBR®?

Should we compress biomaterials or not?
Verena Vermeulen | Switzerland

Does bone regeneration work better in a defect site loosely filled with a bone substitute material, or is compression of the biomaterial beneficial? Prof. Jung-Chul Park, Korea, is among the first researchers to investigate this question in a clinical study. Here he talks with Niklaus Stiefel from Geistlich’s research department about existing evidence and speculation in the field of compressive forces.

“Customized treatments are definitely beneficial”

The number of possible treatments for bone augmentation is quite large. Which one is advisable to use and for what situation? How do new technologies work? We met Prof. Andy Temmerman, University of Leuven, during Osteology Barcelona and he gave us some insights into the topic.

“Simplified treatment is not necessarily good treatment”
Verena Vermeulen | Switzerland

Do dentists and patients have unrealistic expectations about what technology can do? With AAP past president Dr Don Clem, we discussed the search for simplified treatment, predictability and what it really takes to become a better surgeon.

Geistlich Bio-Oss® is an option for augmenting atrophic bone

Causing a low pro-inflammatory response, Geistlich Bio-Oss® integrates into the augmentation site, serves as a scaffold, and reduces the ingrowth of connective tissue.1

Use of Yxoss CBR® in the anterior area
Prof. Frank Liebaug | China

The disadvantages of bone blocks for large bone augmentation are significant – graft resorption, harvest site morbidity, poor graft integration and limited blood supply. Yxoss CBR® provides an alternative approach using particulate graft material.

When the company meets the university

Geistlich believes in strategic collaborations with universities, and with the University of Geneva, Geistlich found a new partner for quality research. Prof. Irena Sailer, Head of Geneva’s Division of Fixed Prosthodontics and Biomaterials, and Dr. Birgit Schäfer, Geistlich’s Executive Scientific Manager, talk about synergies between the two organizations.

“Explantation is a decisive turning point for the patients”
Verena Vermeulen | Switzerland

Explantation can be a last resort to handle an infected implant. Dr. Mauro Merli, Italy, has gained experience in this unpleasant procedure and the subsequent rebuilding of jaw bone. Here he shares his insights into minimally invasive techniques, suitable materials and the value of listening to the patient’s expectations.

Proper flap and suture techniques are key to success
Dr. Luca De Stavola | Italy

Major bone augmentations with either Guided Bone Regeneration or a bone block increase bone volume significantly. But without proper flap techniques, wound dehiscences can jeopardize success.
