CLINICAL CASE 1 – Patient with missing teeth 3, 4 and 5 in combination with horizontal and vertical atrophy. Situation incompatible with ideal and prosthetically guided implant insertion. 2 – Initial CBCT showing vertical and horizontal bone deficit. 3 – 3-D model obtained from CBCT with the corresponding Yxoss CBR® design. 4 – Final titanium scaffold ready for use. 5 – Exposure of the bone defect with full thickness flap. 6 – Fixation of Yxoss CBR® filled with a mix of autologous bone chips and Geistlich Bio-Oss® using two titanium screws. 7 – Coverage with a Geistlich Bio-Gide® membrane. 8 – Tension-free hermetic suture of the flap. 9 – After 8 months, the adequate rooting of the bone graft is assessed by CBCT and the insertion of the implants is planned in a prosthetically guided manner. 10 – 8 months after the GBR the scaffold is removed and two endosseous implants are inserted. 11 – Radiography with three elements supported by implants. 12 – Final prosthetic reconstruction 3 months after implant placement, without the need of a temporary interim solution.
