CLINICAL CASE

1 – Initial clinical situation showing an extended horizontal and vertical bone gap at former positions of teeth 3 and 4 which were extracted 8 weeks earlier.
2 – CBCT showing a deficient vestibular contour and the corresponding bone defect. 3-D design of Yxoss CBR® derived from the patient’s anatomy.
3 – Surgical situation with horizontal and vertical bone defect.
4 – After testing the adaptation of Yxoss CBR® to the defect, it is filled with a graft consisting of 30% autologous particulate bone and 70% granules of Geistlich Bio-Oss®.
5 – Yxoss CBR® fixed with titanium screws.
6 – Adaptation of Geistlich Bio-Gide® over the structure. Complete, tension-free wound closure will follow.
7 – Sites at the day of the procedure after sutures placed. Tunnel between #23,24 and partial thickness flap raised between #23,22.
8 – Radiographic situation after 6 months of healing, before reopening.
9 – Insertion of two implants (Straumann® BLT). The resonance frequency measurement shows ISQ values of 70-75.
10 – Insertion of the healing abutments and adaptation of the flap.
11 – Soft tissue maturation 12 weeks after implant insertion.
12 – Clinical situation after prosthetic finalization, 18 months after surgery. X-ray shows stability of marginal bone levels.
