Summary
Short implants (length < 10 mm) show comparable survival rates to standard-length implants (≥ 10 mm) in grafted bone. This systematic review indicates short implants are a viable, cost-effective alternative for treating atrophic arches.
Area of Science:
- Dental Implantology
- Oral Surgery
- Biomaterials
Background:
- Dental implant success relies on osseointegration and long-term stability.
- Grafted bone presents unique challenges for implant placement.
- Comparing short and standard-length implants in augmented bone is crucial for treatment planning.
Purpose of the Study:
- To systematically review and compare survival rates of short versus standard-length implants in grafted bone.
- To analyze secondary outcomes including marginal bone loss and prosthesis survival rates.
Main Methods:
- Systematic review of randomized controlled trials (RCTs) published until June 2016.
- Searches included electronic databases and manual bibliographical searches.
- Data analyzed for implant survival, marginal bone loss, and prosthesis failure rates.
Main Results:
- Eight RCTs involving 458 short and 488 standard-length implants were analyzed.
- Implant survival rates were high for both groups (96.7% for short, 97.3% for standard).
- No significant differences were found in implant failure, marginal bone loss, or prosthesis failure rates between short and standard implants.
Conclusions:
- Short implants demonstrate comparable survival and stability to standard-length implants in grafted bone.
- Short implants offer a potentially more affordable and less invasive treatment option for atrophic arches.
- Further long-term RCTs are recommended to confirm the long-term predictability of short implants.
