Custom Titanium Ridge Augmentation Matrix (CTRAM): Ideal Augmentation Technique?

custom-meshWith major yearly advances in CAD/CAM dentistry (computer-aided design and computer-aided manufacturing), it seems inevitable that new augmentation techniques will be developed that should lead to major improvements over current treatment protocols. One very interesting area of development is a novel bone augmentation technique using a custom titanium ridge augmentation matrix (CTRAM). The CTRAM is fabricated by utilizing information digitally obtained from CBCT scans to produce virtual augmentations and custom designs, which are then additively manufactured.

A recent study 1 reported on 2 cases using the custom titanium ridge augmentation matrix (CTRAM) method and concluded:

The CTRAM design allows for preoperative planning for increasing alveolar ridge dimensions to support dental implants, reduces surgical time, and prevents the need for a second surgical site to gain sufficient alveolar ridge bone volume for dental implant therapy.1

Another study 2 went even further in praising CTRAM stating:

The combination of CT imaging and CAD technology to create CTRAM from virtual 3D models of the jaw allows for precise pre-surgical planning, resulting in an ideal augmentation of the patient’s defect. This technology enables 1) pre-surgical determination of required bone for ridge augmentation to facilitate future implant placement, 2) reduction of intraoperative time, and 3) application of the critical principle of rigid space maintenance.2

What are your thoughts on CTRAM and it’s potential adoption in GBR?

      Yes, the idea is excellent but I would think the cost would have to competitive with conventional matrices to make it “worth it”. I wonder if the CT obtained matrix might be milled from something resorbable…THAT would be nice.
