Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Horizontal bone gain (mm)

    Horizontal bone gain will be assessed using CBCT scans performed preoperatively, immediately postoperatively, and 6 months postoperatively. Measurements will be taken at standardized reference points perpendicular to the alveolar ridge.

    6 months

Secondary Outcomes (3)

  • Vertical bone gain (mm)

    6 months

  • Gained bone volume (mm³)

    Immediate postoperative

  • Graft resorption volume (mm³)

    6 months

Study Arms (2)

Prebent titanium mesh

ACTIVE COMPARATOR

Ridge augmentation was performed using a prebent titanium mesh adapted on a stereolithographic model. The graft consisted of a mixture of autogenous bone and xenograft in a 60:40 ratio. The mesh was fixed using titanium screws to maintain space for bone regeneration.

Procedure: Prebent titanium mesh augmentation

Customized PEEK mesh

EXPERIMENTAL

Ridge augmentation was performed using a patient-specific CAD/CAM milled PEEK mesh. The graft consisted of a mixture of autogenous bone and xenograft in a 70:30 ratio. The mesh was fixed using titanium screws to maintain space for bone regeneration.

Procedure: Customized PEEK mesh augmentation

Interventions

Guided bone regeneration using a prebent titanium mesh combined with a mixture of autogenous bone and xenograft in a 60:40 ratio.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adult patient of both sexes presenting with a partially edentulous maxillary ridge with a horizontal bone defect.
  • The horizontal ridge dimension measured 2mm below the alveolar crest should range from 2-5 mm.
  • No local pathosis that may interfere with bone healing.

  • All patients suffering from any systemic disease that may affect bone healing.
  • Heavy smokers (more than 10 cigarettes per day)
  • Patients with parafunctional habits such as bruxism and clenching
  • Poor interest and cooperation from the patient.
  • Patients who have undergone any horizontal augmentation procedure at the site of interest
