Short versus Standard Length Implants with Sinus Floor Elevation for the Atrophic Posterior Maxilla

Area of Science:

• Dentistry
• Oral Surgery
• Implantology

Background:

• Maxillary sinus floor elevation is a common procedure for standard length dental implants in atrophic posterior maxilla.
• Short dental implants offer a less invasive alternative by avoiding augmentation procedures.

Purpose of the Study:

• To compare clinical and radiological outcomes of short dental implants in pristine bone versus standard length implants with sinus floor elevation.

Main Methods:

• A clinical study compared 126 short implants (pristine bone) with 312 standard implants (sinus floor elevation).
• Outcomes assessed included cumulative survival rates, 5-year survival rates, marginal bone loss, and oral health-related quality of life (OHRQoL).

Main Results:

• Cumulative survival rates were high for both groups (91.8% for short implants, 92.4% for standard implants).
• Mean marginal bone loss was significantly lower in the short implant group (0.70 mm) compared to the augmented group (0.96 mm).
• Both groups reported comparable and promising OHRQoL.

Conclusions:

• Short dental implants in the resorbed posterior maxilla achieve similar clinical and radiological results to standard implants with sinus floor augmentation.
• Short implants may be a viable alternative, potentially reducing invasiveness and complications associated with augmentation procedures.
