CLINICAL CASE

1 – 3D reconstruction from CBCT images showing horizontal maxillary atrophy at the two-teeth gap.
2 – Intraoperative view of the atrophied anterior maxillary site. Tenting screws are placed to support the collagen membrane.
3 – Application of a mixture (1:1) of autologous bone chips from the retromolar area and Geistlich Bio-Oss®.
4 – Coverage with a double layer of collagen membrane Geistlich Bio-Gide®.
5 – Tension-free, primary wound closure by mattress and single interrupted sutures.
6 – Situation at re-opening after 6 months showing vital bone and reconstructed ridge contour.
7 – Guided implant placement in regenerated bone with stent (additional implant placement at position 22).
8 – Final prosthetic restoration.

CLINICAL CHALLENGE:

  • Insufficient alveolar ridge width for implant placement
  • Donor site morbidity after autologous bone block harvesting and resorption of autologous bone

AIM/APPROACH:

  • Horizontal alveolar ridge augmentation with Geistlich Bio-Oss® and Geistlich Bio-Gide®
  • Minimizing autologous bone harvesting and resorption protection
