Combination with 3D via F. Khoury’s technique

Dr. Mehdi Merabet
Marseille, France


Clinical challenge

A pneumatized sinus cavity was localized in the area of the anteriormaxilla. Due to the atrophic alveolar crest it was impossible to place the implant in a correct position to achieve an appropriate esthetic rehabilitation.


Clinical outcome at a glance


  • Later sinus floor elevation in combination with bone regeneration with 3D using F. Khoury’s technique.
  • Fixed prosthetic restoration in the upper and anterior area.


  • Two-stage sinus floor elevation treatment.
  • Sinus floor elevation using Geistlich Bio-Oss® maintains long term stability of the augmented bone volume.
  • Using Geistlich Bio-Oss® particles in combination with autologous bone chips limits the resorption rate of the augmented site.

Aim / Approach

Lateral sinus floor elevation with Geistlich Bio-Oss® was performed in the area of the right canine/premolar. In this case the minimal invasivelateral window approach allows a better blood supply in the reconstructedregion.

Following the sinus floor elevation abone reconstruction of the alveolar crest was performed with 3D using F. Khoury's technique. The bone block was harvested from the ramus. After preparation of the two blocks each were fixed with a screw in the upper frontal area. The residual spaces between and around the blocks were filled with a mix of Geistlich Bio-Oss® particles and autogenous bone chips.


Grafting with Geistlich Bio-Oss® particles in the sinus cavity maintains the long term stability of the regenerated bone volume. It provides the patient a comfortable and predictable solution.

Reconstructing the alveolar crest with 3D via F. Khoury's technique in combination with the use of Geistlich Bio-Oss® minimizes the volume/size of the harvested bone block. Due to the slow resorption rate of Geistlich Bio-Oss® particles the bone volume is maintained and therefore the aesthetic result.
