Table 2 Volumetric gain stratified by the occurrence of premature CTRAM exposure

From: Volumetric changes in edentulous alveolar ridge sites utilizing guided bone regeneration and a custom titanium ridge augmentation matrix (CTRAM): a case series study

Case outcome Mean planned augmentation volume (mm3) Mean post-graft volume (mm3) Mean percentage bone fill
Premature CTRAM exposure 438.687 274.403 61.296 ± 33.69
No premature CTRAM exposure 293.211 311.948 104.851 ± 15.52
