Summary
This study found that BioHorizons dental implants, designed for bone quality, showed high survival rates (99.4%) and minimal crestal bone loss. The bone-quality based design appears to reduce implant failure and bone loss across different bone densities.
Area of Science:
- Dental Implantology
- Biomaterials Science
- Oral Surgery
Background:
- Crestal bone loss is a critical factor in dental implant success.
- Understanding bone remodeling phases is essential for predicting implant outcomes.
- BioHorizons offers a bone quality-based implant system with various designs.
Purpose of the Study:
- To evaluate the survival rates and crestal bone loss associated with BioHorizons implants.
- To identify critical phases of bone loss during the implant treatment timeline.
- To assess the influence of implant design and bone density on outcomes.
Main Methods:
- Prospective study of 975 BioHorizons implants across four designs.
- Monitoring surgical survival and crestal bone levels at different stages.
- Analysis of bone loss during remodeling, transition, and early loading phases.
Main Results:
- Surgical survival rate was 99.4%, with 100% survival in D4 bone.
- Mean vertical bone loss: 0.21-0.36 mm (Stage I-II), 0.12-0.20 mm (Stage II-prosthesis).
- Mean early loading bone loss was 0.29 mm; no early failures occurred.
Conclusions:
- BioHorizons bone quality-based implant designs demonstrate high survival and minimal crestal bone loss.
- The implant system appears effective regardless of bone density.
- The identified bone loss phases provide insights into implant healing and maintenance.
