Following tooth extraction, the alveolar ridge undergoes horizontal and vertical dimensional changes. It is common to see approximately 50% of the alveolar width and height resorbed1,2 within the first three months3. This can lead to ridge deformation and other complications.
Problems associated with ridge resorption for crown and bridge restorations include:
- Gap between the pontic and the soft tissue of the ridge
- Impaired phonetics
- Impaired esthetics
- Hygiene complications
Problems associated with ridge resorption for implant placement procedures include:
- Insufficient bone for implant placement
- Need for subsequent invasive Guided Bone Regeneration treatment
Ridge preservation with Geistlich biomaterials
The use of scientifically documented biomaterials such as Geistlich Bio-Oss Collagen® and Geistlich Bio-Gide® in ridge preservation procedures can provide new bone formation and restore the hard tissue2,3. Regenerative treatment also may result in:
- Reduced number of secondary augmentations at implant placement2.
- Superior volume preservation under pontics4.
A regenerative approach with Geistlich Bio-Oss Collagen® and Geistlich Bio-Gide® to prevent hard tissue loss following a tooth extraction.
Gap formation when no ridge preservation is performed.
Ridge contour preserved when ridge preservation is performed.
Sealing an extraction socket with Geistlich Mucograft® Seal can further improve soft-tissue parameters in extraction sockets with preserved buccal walls5.
These cases illustrate approaches for ridge preservation with Geistlich Biomaterials.
