Abstract
It is popular in these days to use a CT simulation data to determine the bone graft volume in dental implant
cases with bone defect and the precise implant placement position. However there has been no report on
converting the simulation data three-dimensionally to fabricate bone augmentation materials.
In this study a HA bone graft was fabricated from a sintered HA block using a CAD/CAM technique based
on the bone augmentation volume data determined by the simulation data. The HA graft was evaluated by
comparing with a resin graft model fabricated by a three dimensional printing (3DP) method based on the
same simulation data.
The HA bone graft by CAD/CAM and the resin bone graft by 3DP was well consistent each other in the
shape , size, and adaptability.
