No results posted yet for this study

Summary

The aim of this study is to determine whether jawbone augmentations using allogeneic and autogenous bone blocks lead to comparable three-dimensional clinical and radiological outcomes.

In addition, the study seeks to investigate whether there are differences regarding safety, biocompatibility, complications, and PROMs.

Furthermore, it aims to clarify whether differences exist between the two groups with respect to implant condition (one year after implantation and during annual follow-ups for up to five years).

Conditions

  • Alveolar Bone Loss

Interventions

PROCEDURE

Alveolar socket preservation with graft and flap surgery

Partially edentulous patients in need of implant therapy and presenting an insufficient bone volume (horizontal ridge width \<5mm) to allow placing a standard diameter implant defect-free in a prosthetically ideal position will be included. In the control group, the blocks will be adapted to the defect site morphology. With a small drill, holes for fixation will be prepared and the bone blocks will be immobilized with one or two screws. Subsequently, a layer of bone particles will be applied if needed to cover the autogenous bone and to fill up voids.

PROCEDURE

allogenic bone block augmentation

Partially edentulous patients in need of implant therapy and presenting an insufficient bone volume (horizontal ridge width \<5mm) to allow placing a standard diameter implant defect-free in a prosthetically ideal position. Based on CT/CBCT scans of the patient, the allogenic bone block has already been virtually designed using 3D CAD/CAM technology prior to surgery. The individually milled bone graft Botiss maxgraft® bonebuilder (allogenic bone block), optional addition of MinerOss® A (allogenic bone granules) will then be covered with Argonaut® (porcine collagenbased membrane).
