Major bone augmentation

Tooth loss, trauma or tumour resection can lead to large bone deficiencies in the alveolar ridge. Reconstructive measures are indicated to augment poor bone quantity.

Autogenous bone blocks harvested from the lower jaw or the iliac crest are the prevailing material used to reconstruct larger ridge defects. However, autogenous bone blocks are subject to a certain degree of resorption1,2.

Application of Geistlich biomaterials to a bone block graft diminishes resorption

  • Geistlich Bio-Oss® bone substitute placed over the graft reduces shrinkage3,4.
  • Geistlich Bio-Gide® collagen membrane covering the augmented area further decreases hard tissue resorption1,2,5-7.

Combining autogenous bone with Geistlich Bio-Oss® and Geistlich Bio-Gide® better preserves augmentation in the long term.
