Patients with missing teeth often lack sufficient bone to receive a dental implant and require bone augmentation grafting. This can be accomplished using a custom titanium ridge augmentation matrix CTRAM. The matrix is designed via 3D computer aided design CADsoftware using a virtual jaw model derived from pre-surgical cone beam computerized tomographyCBCT. The matrix is then printed in titanium alloy and sterilized. The CTRAM is surgically fixated to the deficient alveolar ridge, filled with freeze-dried bone allograft FDBA, and covered with a resorbable collagen membrane. In this prospective observational study, up to 14 patients treatment planned to receive one or more dental implants will be consented for evaluation of the clinical outcome of bone augmentation using CTRAM. The changes in their alveolar ridge dimensions will be assessed by three methods.
