Scientific background
Bone and soft-tissue remodeling after tooth extraction has been investigated thoroughly.
Clinical studies show that:
- after tooth extraction, severe volume loss occurs because of bone and soft-tissue resorption1–5
- two-thirds of resorption take place within the first three months1
Therefore, at the time of implant placement and if no Ridge Preservation is performed,
- the need for Guided Bone Regeneration is ten times higher6
- the need for Sinus Floor Elevation is two times higher and the number of more invasive procedures four times higher7

On the other hand, several studies, including randomized controlled clinical trials and meta-analyses, show that Ridge Preservation with Geistlich biomaterials can:
- prevent horizontal and vertical volume loss even in sites with thin buccal bone walls8
- optimize the bone and soft-tissue situation irrespective of the chosen time for implantation5,9-16
- improve the esthetic outcome by preserving the alveolar ridge volume and contour under pontics17
