‘Radiographic evaluation of different techniques for ridge preservation after tooth extraction: a randomized controlled clinical trial’ published by Jung et. al. 2013, evaluated radiographic changes of the alveolar ridge following application of different ridge preservation techniques.
Horizontal bone loss in the Geistlich Bio-Oss® Collagen groups (using either Geistlich Mucograft® Seal or autogenous tissue punch), were reported at 17% and 18% respectively, 6 months following tooth extraction. Where no graft was used (spontaneous healing), horizontal bone loss of 43% was observed. But the ß-TCP / synthetic bone graft group showed horizontal bone loss of 78%.
So the groups using Geistlich biomaterials maintained 82% of the ridge width, compared to only 22% in the ß-TCP group.
The authors concluded that horizontal bone loss following tooth extraction was significantly reduced using a slowly resorbing grafting material.’
