Customized bone regeneration with Yxoss CBR®
Dr. Marcus Seiler | Germany

Yxoss CBR® is a customized titanium grid structure designed for the regeneration of bone defects – based on a patient’s CBCT or CT data. It stabilizes the graft in the optimal position and can be easily removed later.

Communication is part of the cure
Dr. Francesca Rossini | Italy, Dr. Michele Rossini | Italy

For patients, an edentulous area is a “gap;” the word “bone” makes people feel uncomfortable; and the word “surgery” in the context of dentistry creates confusion. What is important when explaining a dental treatment to patients?

How to plan bone reconstructions
Dr. Ueli Grunder | Switzerland

Anyone planning bone regeneration should never just follow a rigid decision tree, but focus instead on the most important connections and factors.

Immediate implant placement - Handling
Ass. Prof. Stephen Chen | Australia

Thick gingivae, an intact facial bone wall, sufficient bone volume on the apical aspect, no infection – ideal conditions for immediate implant placement. How to do it?

3-D imaging for treatment planning
Assistant Prof. George A. Mandelaris | United States

3-D imaging has revolutionized pre-treatment case analysis and treatment planning. This article addresses the role of CBCT imaging in interdisciplinary dentofacial therapy for skeletally mature patients requiring orthodontic therapy.

Regeneration during sleep
Dr. Klaus Duffner | Germany

Being unconscious and defenseless for hours at a time poses a risk for every living creature. What makes sleep so important that it is worth taking the risk?

Implant placement with GBR
Prof. Daniel Buser | Switzerland

Circumferential bone anchorage in the alveolar ridge is key to the long-term success of an implant. Therefore, bone defects at the implant site have to be corrected by means of GBR.

Taking the patient’s view into account
Dr. Michael McGuire | United States

Objective treatment outcomes are measurable and comparable. However, it is also worth taking the patient’s subjective measures into account. This is the goal of “patient-reported outcomes.”

The early days of GBR
Prof. Jan Lindhe | Sweden

Jan Lindhe shaped periodontology and implant dentistry research like few others. Here he looks back to the early days of oral tissue regeneration and compares 1985 to 2015.

Autogenous bone plus biomaterials
Prof. Matteo Chiapasco | Italy

Autogenous bone grafts stimulate new bone formation but are prone to resorption. Biomaterials are merely osteoconductive but maintain the volume. So, how about combinations of the two materials?

Socket Sealing
Ass. Prof. Stefan Fickl | Germany

Should the extraction socket be sealed with a soft-tissue punch graft or with a collagen matrix? The matrix has some advantages over the autologous punch.

Options post tooth extraction
Prof. Ronald E. Jung | Switzerland

Immediate implantation, spontaneous healing or Ridge Preservation – these are the available options after a tooth has been extracted. Which option is the best when?

How to use bone blocks
Prof. Carlo Maiorana | Italy

Surgeons can avoid complications with autogenous bone blocks if they use adequate incision techniques, rigidly fix the block and cover it with a suitable granulate bone substitute and membrane.

How prevalent is peri-implant disease?
Prof. Niklaus P. Lang | Switzerland

Estimates put the incidence of peri-implantitis at around one percent per year. But there are no clear definition criteria and the frequency of peri-implantitis differs by patient group.
