Four questions on Straumann biomaterials

After tooth extraction, a series of physiological changes affecting the surrounding alveolar bone take place. This process includes bone formation as well as volumetric resorption, and the latter can compromise implant placement in a prosthetically driven position or the clinical outcome. In an upcoming webinar, which will be broadcast live on 7 July, Drs Susy Linder and Michel Dard will explain the clinical decision-making process after tooth extraction. Prior to the online presentation, the experts answered a few questions for Dental Tribune International on the use of biomaterials in this regard.

How can biomaterials help to prevent bone resorption after tooth extraction?
Dard: The general principle of biomaterials is to act as a space holder between and/or inside the granules, depending on their size, for bone grafting materials like cerabone and underneath the material itself for membranes like Jason membrane. Depending on the clinical situation, these materials can be used alone or together because they complement each other. These two space maintainers facilitate biological fluid intrusion, vascularisation, bone marrow development and eventually bone growth. Because they protect the “living space”, they can be considered bone promoters, avoiding bone resorption after tooth extraction.

Which treatment methods after tooth extraction will you discuss in your webinar?
Linder: We will discuss hard- and soft-tissue management for immediate implant placement and alveolar ridge preservation/augmentation (including socket sealing, socket filling and guided bone regeneration) with the use of bovine bone grafts, collagen membranes and soft-tissue grafts. Moreover, we will address the importance of the use of healing enhancers during these treatment approaches.

Which Straumann biomaterials will you cover in your webinar, and what advantages do they offer for treatment outcomes and patients?
Linder:
We will discuss cerabone and Straumann XenoGraft. These bovine bone grafting materials are easy to handle and to apply. Furthermore, they are excellent performers, as they present short- and long-term volume stability and osteoconductive properties.

In addition, we will present the user-friendly collagen Jason membrane, which has high tensile strength and reliable thickness. It serves as a scaffold for both nutrition transfer and long-term barrier function. Moreover, it allows secondary healing in case of exposure and is suitable for complex procedures.

We will also speak about Straumann Emdogain. These enamel matrix derivatives are indicated for periodontal regeneration and enhance healing. Emdogain promotes angiogenesis, modulates inflammation, and reduces post-surgical pain and swelling. These properties can improve patient satisfaction and morbidity.

What has been your personal experience with the Straumann biomaterials?
Dard:
Cerabone and Jason membrane are easy to use. The first one is to be mixed with blood just before its application and the second to be hydrated before application. Both biomaterials show a high level of usability, and this property will be further discussed in our webinar.

Editorial note: The webinar, titled “Confidence in extraction socket management and immediate implant placement with Straumann Biomaterials”, will be presented live on Tuesday, 7 July, at 12 p.m. CEST. Participants will have the opportunity to ask questions about the topic as well as earn a continuing education credit by answering a questionnaire after the lecture. Registration on the Straumann Campus is free of charge.
