Titanium Mesh vs Customized PEEK Mesh for Horizontal Maxillary Ridge Augmentation: A Randomized Clinical Trial

Sponsor: Basma Alsheikh

Summary

Background: Reconstruction of the deficient maxillary ridge in three dimensions is crucial for the successful placement of implants. Prebent titanium meshes are an established modality for GBR, while patient-specific PEEK meshes have recently emerged with some possible advantages over the former. This study compared the effectiveness of these two modalities for bone augmentation. Materials and Methods: 14 patients with 28 augmented sites in the maxillary ridges of primarily horizontal bone deficiencies, often associated with minor vertical components, were randomly assigned to two groups. The control group (n=7) was augmented with a prebent titanium mesh, while the study group (n=7) was augmented with a customized milled PEEK mesh. Both were grafted with a mixture of autogenous bone and xenograft. The primary outcome was horizontal bone gain. Secondary outcomes included vertical bone gain, gained bone volume, and graft resorption. These parameters were assessed by CBCT preoperatively, immediately postoperatively, and at 6 months before implant placement.
