Summary
Titanium meshes combined with dental implants successfully regenerated horizontal bone, achieving significant bone gain. This approach demonstrated high implant survival rates with manageable complications, indicating a promising regenerative treatment.
Area of Science:
- Dental Implantology
- Periodontology
- Regenerative Medicine
Background:
- Guided bone regeneration (GBR) is crucial for dental implant success in atrophic alveolar ridges.
- Titanium meshes are utilized for GBR, but their outcomes with simultaneous implant placement require further evaluation.
Purpose of the Study:
- To assess horizontal bone augmentation using titanium meshes placed concurrently with dental implants.
- To determine implant survival rates and complication profiles in this patient cohort.
Main Methods:
- A retrospective multicenter study included 25 patients with 40 implants.
- Titanium meshes (i-Gen®) were used for simultaneous guided bone regeneration and fixed over implants.
- Cone-beam computed tomography (CBCT) evaluated horizontal bone gain; implant survival and complications were primary and secondary outcomes.
Main Results:
- Mean horizontal bone gain of 3.67 mm (±0.89) was observed post-mesh removal.
- Implant survival rate was 97.5% after one year, with mean marginal bone loss of 0.43 mm (±0.15).
- Common complications included mild edema (48%) and discomfort (40%), resolving within a week. Titanium mesh exposure occurred in 24% of patients.
Conclusions:
- Simultaneous placement of titanium meshes with dental implants provides predictable horizontal bone reconstruction.
- The technique shows favorable implant survival and manageable complication rates.
- Further prospective randomized controlled trials with larger sample sizes are recommended to confirm these findings.
