International Journal of Implant Dentistry

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

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
p value^a	0.287	0.778	0.0355
