CLINICAL CASE

1 – Exposure of the alveolar ridge and buccal bone.
2 – Horizontal and vertical osteotomies of the distracted segment.
3 – The upward lift of the transported segment, achieving a height gain of 7 mm.
4 – Geistlich Bio-Oss® Block is trimmed in a dry state with a piezo surgical device to the required dimension and shaped to completely fit into the recipient site.
5 – The coronally shifted segment is fixed with miniplates and miniscrews and thus immobilizes also the biomaterial block.
6 – The coronally shifted segment is fixed with miniplates and miniscrews and thus immobilizes also the biomaterial block.
7 – Intra-operative situation following implants insertion 4 months after interpositional grafting.
8 – Periapical X-ray evaluation immediately after implant insertion.

CLINICAL CHALLENGE:

  • Insufficient alveolar ridge height for implant placement and proximity to the alveolar nerve
  • Autologous bone harvesting is associated with patient discomfort

AIM/APPROACH:

  • Interpositional grafting with Geistlich Bio-Oss® Block for vertical augmentation
  • Alveolar ridge volume preservation and minimizing patient morbidity
