Gewebebewahren

Gewebebewahren is a term used in German-speaking medicine and dentistry to describe an approach that aims to protect and preserve natural tissues during surgical interventions. The concept emphasizes maintaining the integrity of soft and hard tissues to support function, aesthetics, and long-term prognosis.

Core idea and principles

The central goal of gewebebewahren is to minimize tissue trauma and disruption of blood supply. This includes atraumatic handling of tissues, minimal incision lengths, careful flap management, and preservation of the mucosal envelope and periosteum. Planning relies on understanding tissue biology, imaging, and selecting techniques and instruments that limit tissue damage. Preservation of bone volume and the continuity of the interdental or gingival tissues is often highlighted to reduce postoperative recession and improve healing.

Applications

In dentistry, gewebebewahren is especially relevant in tooth extraction with socket preservation, implantology, and periodontal therapy. Techniques such as minimally invasive access, papilla-sparing flap design, atraumatic extraction, guided surgery, and use of resorbable membranes or graft materials may be employed to protect surrounding tissues. In other surgical fields, the principle guides procedures where tissue preservation is linked to better functional and cosmetic outcomes, such as reconstructive, oncologic, and soft tissue surgeries.

Outlook and considerations

Gewebebewahren is seen as a planning- and technique-oriented philosophy rather than a single procedure. Its effectiveness depends on case selection, surgeon experience, and patient-specific factors. While beneficial in many scenarios, complete tissue preservation may not be possible in all conditions, and trade-offs between oncologic safety and tissue conservation may arise.
