Short implants without bone augmentation vs. long implants with bone augmentation: systematic review and...

Area of Science:

• Dental Implantology
• Oral Surgery
• Regenerative Medicine

Background:

• Anatomical limitations like the lower alveolar nerve and maxillary sinus proximity in atrophied jaws can complicate dental implant surgery.
• Bone augmentation is often required to overcome these limitations, increasing treatment complexity and duration.

Purpose of the Study:

• To conduct a systematic literature review comparing short dental implants with standard-length implants following bone augmentation.
• To determine the efficacy and safety of short implants as an alternative in complex anatomical situations.

Main Methods:

• A systematic literature search was conducted using the PRISMA methodology.
• Clinical trials published between 2010 and 2020 were retrieved from the Medline database.
• Keywords included "short versus long implants," "augmented bone," and "clinical trial."

Main Results:

• Meta-analyses revealed no statistically significant difference in implant loss rates at 1, 3, and 5 years between short and standard implants.
• Complication rates were significantly higher in the control group (standard implants) after 1 year.
• Marginal bone loss showed no statistically significant difference between the groups across all follow-up periods.

Conclusions:

• Short dental implants represent a suitable alternative to standard-length implants, particularly when bone augmentation is a consideration.
• Utilizing short implants may lower the risk of complications due to the potential avoidance of bone augmentation procedures.
