Comparison of Customized Allogenic Versus Autogenous Bone Block Graft for Alveolar Ridge Augmentation
Trial Parameters
Brief 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).
