Summary
Customized titanium meshes alone showed comparable results to those with collagen membranes for bone augmentation. While membranes showed slightly better outcomes, both methods proved effective for soft tissue healing and bone regeneration.
Area of Science:
- Oral surgery and implantology
- Biomaterials science
- Regenerative medicine
Background:
- Alveolar bone defects often require augmentation for dental implant placement.
- Customized titanium meshes are used for bone regeneration, but their efficacy with resorbable membranes needs evaluation.
- Soft tissue healing is crucial for successful bone augmentation outcomes.
Purpose of the Study:
- To assess the role of resorbable membranes over customized titanium meshes in bone augmentation.
- To compare soft tissue healing and bone regeneration between meshes with and without membranes.
- To evaluate healing complications and regenerated bone volume in patients needing implant-supported restorations.
Main Methods:
- Thirty patients with alveolar bone defects were randomized into two groups: custom meshes only (Mesh-) or custom meshes with cross-linked collagen membranes (Mesh+).
- Data collected included complications, pseudo-periosteum thickness, bone density, planned bone volume (PBV), regenerated bone volume (RBV), regeneration rate (RR), and vertical bone gain (VBG).
- Implant survival in regenerated areas was also assessed, with statistical analysis performed at α = 0.05.
Main Results:
- Healing complication rates were 33% for Mesh- and 13% for Mesh+, though not statistically significant.
- Regenerated bone volume (RBV) was 803.27 mm³ for Mesh- and 843.13 mm³ for Mesh+.
- Regeneration rate (RR) was higher in Mesh+ (82.3%) than Mesh- (74.3%), but without statistical significance. All implants placed were clinically stable.
Conclusions:
- Customized meshes alone are not inferior to those covered by collagen membranes regarding healing complications and regeneration rates.
- While not statistically significant, customized meshes with membranes showed superior outcomes for all evaluated variables.
- Both augmentation techniques demonstrated effectiveness, supporting their use in implant dentistry.
